The Inspiration Behind This Bistro Egg Sandwich Recipe

The journey to perfecting this ultimate egg sandwich recipe began during a memorable bloggers retreat in the vibrant heart of downtown Nashville. It was there, at a charming and bustling spot named “Steadfast Coffee,” that I first encountered their truly exceptional egg sandwich. It was an instant favorite, unlike any I had tasted before, prompting an immediate desire to meticulously recreate its magic in my own kitchen.

Steadfast Coffee’s rendition was a masterpiece of textures and flavors. It featured scrambled eggs, expertly cooked to resemble a single, fluffy omelet patty rather than loose, crumbly curds. This substantial and tender egg base was then generously layered with the distinct kick of grainy mustard, a rich spread of their unique Calabrian mayo (a creamy mayonnaise infused with savory Italian peppers specifically from the Calabria region), fresh, peppery arugula greens, and wonderfully tart pickled onions. All these incredible components were perfectly nestled within a golden, perfectly toasted brioche bun.

From the very first bite, I knew I had stumbled upon something truly special. It was a symphony of bold and nuanced flavors: the vibrant pungency from the pickled onions and the spicy-sweet depth of the sauces, perfectly balanced by the subtle sweetness and buttery richness of the brioche bun, all rounded out by the comforting heartiness of the egg and cheese. Despite its substantial and gourmet appearance, the sandwich was so harmoniously balanced that I devoured the entire thing and still felt light and perfectly satisfied afterward. These sandwiches aren’t just incredibly delicious; they’re also visually stunning, making them absolutely ideal for a gourmet brunch spread. Plus, any leftovers reheat wonderfully, maintaining their deliciousness. For those planning to feed a larger gathering, I even have a brilliant make-ahead tip for the eggs that will save you precious time!

What is Calabrian Mayo? The Secret Sauce for Your Gourmet Egg Sandwich

The irresistible magic of this bistro-style egg sandwich largely lies in its distinct and incredibly flavorful sauce: Calabrian mayo. But what exactly is this tantalizing condiment? Simply put, it’s a luscious and creamy mayonnaise generously infused with the vibrant flavor and mild yet pronounced heat of authentic Italian Calabrian chili peppers. These unique peppers, which proudly hail from the sun-drenched Calabria region of Southern Italy, are celebrated for their distinctive flavor profile: a delightful and complex balance of medium heat, subtle underlying sweetness, and a pleasant tangy undertone.

Calabrian chilies are notably milder than traditional cayenne peppers, offering a warm, inviting spice that enhances the overall flavor without overpowering the other ingredients, making them the perfect choice for a sophisticated sandwich spread. These versatile peppers are known by various names, including “hot Calabrian Chile pepper,” “Small Red Cherry pepper,” and “Peperone Picante Calabrese,” which elegantly translates to “spicy pepper of Calabria.” This pepper delivers a rich, complex flavor that is both savory and faintly fruity, leaving a pleasant, lingering warmth on the palate. To incorporate them into mayonnaise, you’ll typically use crushed Calabrian chili peppers preserved in oil, which not only provides a desirable rich texture but also deeply infuses the mayo with their distinctive and aromatic taste.

If you find yourself having trouble sourcing crushed Calabrian chili peppers, don’t fret! A fantastic and widely available substitute that captures a similar profile is cherry pepper spread or, alternatively, whole pickled cherry peppers. You can often locate pickled cherry peppers in the condiment or international foods aisle of most major grocery stores, such as Publix. If you purchase whole ones, simply chop them finely at home. The critical element is to use the pickled variety, as their tart, vinegary essence is absolutely crucial for achieving that authentic tangy dimension and balancing the richness in your homemade Calabrian mayo. This zesty condiment is truly what elevates this egg sandwich from simply delicious to an unforgettable gourmet experience!

Choosing the Perfect Bread: Brioche Buns and Delicious Alternatives

The foundation of any truly great sandwich is its bread, and for this bistro-style egg sandwich, a luxurious brioche bun is highly recommended for achieving the authentic cafe experience. Brioche is a celebrated French yeast bread, renowned globally for its incredibly rich, tender crumb, its beautiful golden color, and its subtly sweet, buttery flavor profile. It stands in stark contrast to a standard hamburger bun, being much more enriched thanks to its significantly higher egg and butter content, which imparts a luxurious texture and a delightful sweetness. This inherent sweetness beautifully complements the savory, spicy, and tangy fillings of our gourmet egg sandwich, creating a harmonious balance of flavors.

The original Steadfast Coffee cafe specifically utilizes brioche buns, and their choice is undoubtedly a key factor in the sandwich’s overall appeal and signature taste. The soft, pillowy interior of the brioche, combined with its lightly toasted, slightly crisp exterior, creates the perfect textural contrast to the fluffy eggs and the vibrant crunch of the additional components.

However, if authentic brioche buns are unavailable in your area or you’re simply looking to explore other options, there are several excellent substitutes that will still yield a fantastic and satisfying egg sandwich:

  • Challah Bread: This traditional Jewish braided bread shares a similar richness and a slightly sweet profile with brioche, primarily due to its generous egg content. Its soft, dense texture makes it an ideal stand-in.
  • Hawaiian Sweet Bread: Known for its distinctive sweetness and incredibly soft, airy texture, Hawaiian sweet bread rolls or buns can also work wonderfully, providing that desirable sweet counterpoint to the savory fillings.
  • Potato Buns: While generally not as sweet as brioche or challah, potato buns offer a remarkably soft, resilient texture that can hold up exceptionally well to the various fillings, preventing sogginess.
  • Whole Wheat Brioche (if available): For a slightly healthier twist without completely sacrificing the beloved classic brioche character, some specialty grocery stores or artisan bakeries might carry whole wheat brioche buns, offering a good compromise.
  • Sourdough Bread: For a more savory and tangy profile, slices of lightly toasted sourdough bread can provide a delightful chew and a complex flavor that pairs wonderfully with the zesty mayo and eggs.

Regardless of your chosen bread, ensuring your bun or slices are lightly toasted is absolutely crucial. Toasting adds a vital textural element – a satisfying crispness – which not only enhances the overall flavor and aroma of the bread but also prevents it from becoming soggy under the weight and moisture of the delicious fillings.

Mastering the Scrambled Eggs: Omelet-Style Perfection for Your Sandwich

The eggs in this gourmet bistro egg sandwich are not prepared as typical loose scrambled eggs; instead, they utilize a specific omelet-style technique that results in a unique and incredibly satisfying patty. This method is key to creating a firm yet wonderfully fluffy egg patty that maintains its shape perfectly within the sandwich, providing a substantial bite unlike fragmented, “bits” of scrambled eggs. This approach is absolutely essential for replicating the authentic cafe experience and constructing a truly robust, easy-to-eat sandwich.

To achieve this coveted perfect texture, you’ll begin by thoroughly beating your eggs with a small amount of liquid, typically water or half-and-half. This addition of liquid is not just for volume; it’s a culinary secret that helps create steam during cooking, which in turn contributes significantly to the eggs’ unparalleled fluffiness and tenderness. Once beaten until light and airy, the mixture is gently cooked in a small frying pan, mirroring the technique used for preparing a classic omelet. The goal is to cook the egg mixture just until it sets, then carefully fold it to create a thick, unified patty that’s ready to be nestled into your bun.

Pro-Tips for Crafting Your Flawless Omelet-Style Egg Patty:

  • Low and Slow for Tenderness: Always cook your eggs over a gentle medium-low heat. This crucial step prevents them from browning too quickly and ensures a consistently tender, creamy, and moist texture throughout.
  • Small Pan, Big Impact: Utilizing a small 8-inch non-stick frying pan is ideal for making individual egg patties. Its size allows the eggs to cook thick enough to be easily folded into a substantial, sandwich-ready patty.
  • Gentle Scrape Technique: As the edges of the eggs begin to set, gently push the cooked portions towards the center of the pan using a rubber spatula. This technique allows the uncooked liquid egg to flow underneath, creating a more uniform patty. Avoid aggressive scrambling.
  • Cover and Steam for Even Setting: Once the eggs are mostly set on the bottom and sides but still a bit wet on top, covering the pan with a lid for just 1 minute is a game-changer. This steaming action helps the top of the egg set perfectly without the need for premature or difficult flipping, resulting in a beautifully uniform patty.
  • Make-Ahead for Large Gatherings: For those occasions when you need to feed a larger crowd, here’s a genius hack: prepare a larger batch of beaten eggs with liquid, then pour it into a greased 12×8-inch baking pan. Bake until fully set, then slice the cooked egg slab into convenient squares. This method is perfect for baked eggs, ensuring consistency and significantly saving time compared to cooking individual patties over the stovetop.

This meticulous yet simple method consistently yields an egg patty that is both firm enough to hold its structural integrity within the sandwich and incredibly fluffy and tender, adding the perfect comforting and luxurious element to your bistro egg sandwich. While the cafe might occasionally vary its egg preparation with a poached egg, this omelet-style scrambled egg remains a consistently delicious, easy, and satisfying choice for our recipe.

Essential Ingredients for Your Bistro Egg Sandwich

Gathering the right ingredients is the fundamental step to successfully replicating the authentic, vibrant taste of this cafe-inspired egg sandwich in your own kitchen. Most of the items are readily available at your local grocery store, with a simple yet effective substitution available for the specialized Calabrian peppers if needed. Both authentic Calabrian and common cherry peppers offer a similar pickled tartness and mild heat, ensuring your sandwich has that signature zesty and complex kick.

  • Brioche Buns: As previously emphasized, these sweet, buttery, and incredibly tender buns are absolutely essential for achieving the authentic taste and luxurious texture that defines this bistro-style sandwich. Remember to toast them to golden perfection!
  • Large Eggs: Use fresh, good-quality large eggs. They are the star ingredient for creating those wonderfully fluffy, omelet-style patties that form the heart of our sandwich.
  • Half and Half & Water: A small, precise amount of this liquid mixture, when whisked thoroughly with the eggs, is the secret to ensuring a truly tender, airy, and moist egg patty.
  • Sunflower Oil (or another neutral-flavored oil): Used for cooking the eggs, a neutral oil like sunflower oil ensures that no competing flavors interfere with the delicate taste of the eggs and other ingredients.
  • Mayonnaise: This forms the creamy base for our incredible and indispensable Calabrian mayo. Opt for a good quality, full-fat mayonnaise for the richest flavor and best texture.
  • Crushed Calabrian Chili Peppers: These are the true flavor heroes for the authentic Calabrian mayo. If you can’t find them in specialty stores or readily online (check online retailers), a cherry pepper spread or finely chopped pickled cherry peppers are excellent and accessible substitutes. Remember, the pickled variety is crucial for their signature tartness.
  • Stone Ground Mustard: This robust, grainy mustard adds a fantastic textural element and a pungent, tangy flavor that provides an essential counterpoint to the richness of the eggs and mayo. You’ll typically find it in the condiment aisle.
  • Cane Sugar: Just a touch of cane sugar in the Calabrian mayo helps to expertly balance the inherent heat and acidity of the peppers, creating a well-rounded flavor profile.
  • Fresh Arugula: These tender baby salad greens offer a delightful peppery bite and a fresh, slightly bitter note that brilliantly cuts through the richness of the sandwich components. You’ll easily find them in the produce section of any grocery store.
  • Pickled Red Onions: These are surprisingly super easy to make at home with a simple brine (find our quick and easy recipe here). Their vibrant color, delightful crunch, and irresistible tangy flavor are absolutely indispensable for this sandwich. If you’re truly short on time, thinly sliced red onions tossed in a splash of apple cider vinegar for a quick marinade can work as an emergency substitute.
  • Swiss Cheese: Slices of Swiss cheese are recommended, but other excellent choices include Baby Swiss, Gouda, or Havarti. These cheeses are chosen because they melt beautifully and offer a mild, slightly nutty flavor that pairs exquisitely with the other bold ingredients.

Optional but Highly Recommended Add-ins: Consider further enhancing your already delicious egg sandwich with some crispy, savory bacon for an added crunch and depth of flavor, or a creamy layer of smashed avocado for extra richness, healthy fats, and a smooth texture. Both additions are fantastic and will elevate your sandwich experience even further!

How To Craft Your Delicious Egg Sandwich: A Step-by-Step Guide

This easy egg sandwich recipe is celebrated for its quick prep and fast cooking time, making it an ideal choice for busy mornings or whenever a craving for gourmet flavors strikes. You have the flexibility to cook the beaten eggs in a small frying pan, preparing two eggs at a time for individual patties. Alternatively, you can take advantage of our brilliant make-ahead tip and bake all the eggs simultaneously in a 12×8-inch baking pan, allowing you to avoid prolonged standing over the stovetop. Furthermore, the star of the show, the Calabrian mayo with its delightful chili peppers, can also be prepared a day in advance, which significantly streamlines your sandwich assembly process!

  1. Prepare the Zesty Calabrian Mayonnaise: In a small mixing bowl, combine the mayonnaise, the crushed Calabrian chili peppers (or your chosen cherry pepper substitute), the additional 1/2 teaspoon of stone ground mustard, and the cane sugar. Whisk all the ingredients together thoroughly until they are completely combined and the sauce is smooth and creamy. Cover the bowl securely and refrigerate the sauce until it is needed. Allowing it to chill helps the flavors meld and intensify, making it even more delicious.
  2. Perfectly Toast the Brioche Buns: Preheat a cast-iron skillet, a griddle, or a regular frying pan over medium heat. Carefully slice each brioche bun in half horizontally. Place the cut sides down onto the hot cooking surface and toast them lightly until they achieve a beautiful golden brown color and are slightly charred at the edges (this usually takes about 1-2 minutes per side). This crucial step adds a vital textural element, providing a satisfying crispness, and helps prevent the buns from becoming soggy when assembled. Set the toasted buns aside.
  3. Cook the Fluffy Omelet-Style Scrambled Eggs: In a medium bowl, thoroughly whisk 2 eggs with 1 tablespoon of water and 1 tablespoon of half and half until the mixture is well combined and slightly frothy. Season lightly with salt and freshly ground black pepper to taste. Heat a small 8-inch non-stick frying pan over medium-low heat and add 1 teaspoon of sunflower oil. Pour the egg mixture into the skillet. Allow it to cook undisturbed for approximately 30 seconds until the edges just begin to set. Using a rubber spatula, gently push the cooked edges towards the center of the pan, allowing the uncooked liquid egg to flow underneath. Continue this gentle motion for another 30 seconds. Now, reduce the heat to low, cover the pan with a lid, and let it steam for 1 minute until the top of the egg is mostly set. Carefully flip the egg patty using your spatula and cook for another 30 seconds, or until it is fully cooked through and lightly golden. Transfer the finished egg patty to a plate. Repeat this exact process two more times to create a total of three omelet-style patties from your 6 eggs.
  4. Form Convenient Egg Patties: Once all your egg omelets are cooked and have slightly cooled, take each large omelet and carefully divide it in half. Then, gently fold each half over itself to create six neat, thick egg patties. These perfectly sized patties will fit beautifully and snugly onto your toasted brioche buns.
  5. Assemble the Gourmet Egg Sandwiches: Begin by taking the bottom halves of your perfectly toasted brioche buns. Spread approximately 1/2 teaspoon of the stone ground mustard evenly across the cut surface of each bun. Next, layer with a generous handful of fresh, peppery arugula, followed by one of your fluffy egg patties, and then a delightful spoonful of your tangy pickled red onions.
  6. Finish with Melted Cheese and Serve: Spread about 1 tablespoon of the chilled Calabrian mayo evenly onto the top half of each brioche bun. Place one slice of Swiss cheese directly over the mayo. For perfectly melted, gooey cheese, microwave the top bun with the cheese for approximately 10 seconds on high power. Once the cheese is beautifully melted and warm, carefully place this cheese-topped bun over your assembled sandwich. Serve your homemade bistro-style egg sandwich immediately and prepare to savor every single bite of this gourmet delight!

Quick Note: If you prefer a more classic take on an egg sandwich, you can certainly substitute the scrambled egg patty with a beautifully fried egg, cooked to your desired doneness (sunny-side up, over-easy, or over-hard). The overall flavor profile will remain just as delicious and satisfying!

What To Serve with Your Gourmet Egg Sandwiches for a Complete Meal

While this bistro egg sandwich is undeniably satisfying and complete on its own, its rich flavors and hearty components make it a fantastic centerpiece for a more elaborate brunch spread or a fulfilling lunch. Here are some delightful accompaniments that will complement your egg sandwich perfectly:

  • Fresh Fruit Medley: Brighten your plate and add a refreshing contrast with slices of juicy oranges, a vibrant and colorful fruit salad, or a simple cup of seasonal berries. The natural sweetness and freshness provide a wonderful palate cleanser.
  • Light Green Salad: A simple yet elegant side salad of mixed greens, dressed lightly with a delicate vinaigrette made from olive oil and vinegar, offers a refreshing counterpoint to the richness of the sandwich and adds a healthy, crisp touch.
  • Sweet Pastries: For a true indulgent cafe experience, pair your savory sandwich with a delicate sweet pastry. Consider a flaky croissant, a tender scone, a fruity Danish, or a mini muffin to complete the spread.
  • Crispy Potatoes: Classic breakfast sides like crispy fried potatoes, golden hash browns (our hash brown recipe is incredibly popular!), or even perfectly seasoned roasted potato wedges make for a hearty and satisfying complement.
  • Yogurt Parfait: A healthy and wonderfully refreshing yogurt parfait, layered with crunchy granola and fresh fruit, can add a creamy, tangy, and texturally interesting element to your meal.
  • Hot Coffee or Tea: No breakfast or brunch is truly complete without your favorite hot beverage. A robust, freshly brewed coffee, an aromatic herbal or black tea, or a creamy latte will perfectly round out the meal.
  • Fresh Juice: A glass of freshly squeezed orange juice, grapefruit juice, or a vibrant mixed berry juice adds a bright, zesty, and refreshing note to balance the rich flavors.
  • Crispy Home Fries: Hearty diced and pan-fried potatoes seasoned with paprika, onions, and garlic are another excellent savory option.

Frequently Asked Questions About This Bistro Egg Sandwich Recipe

How To Cook Scrambled Egg Patties for Breakfast Sandwiches?

Achieving the perfect, fluffy yet structured egg patty for your breakfast sandwich is easier than you might think, and it makes all the difference! While there are many ways to prepare eggs for sandwiches (fried whole, baked in ramekins, or using molds), our preferred method for a soft yet perfectly structured patty falls delightfully between traditional scrambled eggs and a classic omelet.

Here’s the detailed technique for making these ideal egg patties: Begin by thoroughly whisking your eggs with the specified liquids (half and half and water) using a wire whisk until they are well combined and visibly light and frothy. Heat a non-stick skillet over medium-low heat with a little oil. Pour the egg mixture into the hot skillet. As the edges of the egg begin to set, gently glide the cooked portions of the egg towards the center with a rubber spatula, allowing the uncooked liquid egg to flow into the empty spaces. Continue this gentle motion until small curds start to form, but the top of the egg is still quite wet. Now, crucial for fluffiness, reduce the heat to low, cover the pan with a lid, and let it cook for about 1 minute. This steaming step helps the top set beautifully without excessive stirring or browning.

After a minute, uncover the pan. Carefully use your rubber spatula to loosen all the edges of the egg omelet from the pan. Then, with a confident and swift motion, flip the entire egg patty to cook the other side for an additional 30 seconds to 1 minute, or until it’s fully set and cooked to your liking, with a light golden hue. Remove the finished patty from the pan. For our bistro sandwich, we then typically cut the large patty in half and fold each piece over to create two thick, fluffy, and perfectly formed egg patties that fit wonderfully on a bun!

Can I Make the Egg Patties and Calabrian Mayo Ahead of Time?

Absolutely, both the egg patties and the Calabrian mayo are excellent candidates for make-ahead preparation, which is fantastic for streamlining your morning routine, especially if you’re serving a crowd or meal prepping for the week. Once cooked and folded, allow the egg patties to cool completely to room temperature. You can then stack them with small squares of parchment paper in between to prevent sticking and store them in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply microwave each patty for 15-20 seconds or gently warm them in a skillet over low heat until heated through.

The Calabrian mayo can also be prepared well in advance. Whisk all the ingredients together, cover it tightly, and store it in the refrigerator for up to a week. The flavors will actually deepen and meld beautifully over time, making it even more delicious on day two or three!

Is This Egg Sandwich Spicy, and Can I Adjust the Heat?

The primary source of spice in this incredibly flavorful egg sandwich comes from the star ingredient: the Calabrian mayo. Calabrian chili peppers are known for their distinct medium heat, which is certainly noticeable but generally milder and more nuanced than the aggressive burn of cayenne. They offer a pleasant, lingering warmth that enhances the overall flavor profile without overwhelming the palate. It’s a delightful, savory heat that many find perfectly balanced.

Yes, you absolutely can adjust the heat level to suit your personal preference! If you prefer a milder sandwich, simply reduce the amount of crushed Calabrian chili peppers you incorporate into the mayonnaise. You can start with half the recommended amount and taste before adding more. Conversely, if you are a true spice enthusiast and love an extra kick, feel free to add a bit more of the crushed peppers to the mayo. Always taste and adjust as you go to achieve your perfect level of zest and heat!

Pro-Tips and Creative Variations for Your Ultimate Egg Sandwich

Ready to customize your bistro egg sandwich, make it even easier to prepare, or explore new flavor dimensions? Here are some invaluable tips and delicious variations to elevate your homemade creation:

  1. Add Crispy Bacon or Sausage: Transform this into a hearty bacon, egg, and cheese sandwich by adding 1-2 slices of perfectly cooked crispy bacon (halved if needed) or a savory breakfast sausage patty to each sandwich. This adds a fantastic layer of smoky flavor and texture.
  2. Season Your Eggs Smartly: Always remember to season your scrambled eggs generously with salt and freshly ground black pepper while they are in the whisking stage. For best adherence and even flavor distribution, add the pepper preferably when the eggs are still slightly wet in the pan.
  3. Experiment with Pickles: While our tangy pickled red onions are phenomenal, feel free to explore other tangy elements. Thinly sliced, tart baby dill pickles can offer a different but equally delicious crunch and sour note. However, we wholeheartedly recommend the vibrant and slightly sweet flavor of the egg and pickled onion combination for the ultimate bistro taste!
  4. Creamy Avocado Boost: For a delightful and incredibly satisfying avocado egg sandwich, mash half of a ripe avocado with a pinch of sea salt and a squeeze of fresh lime juice, then spread it generously onto one side of the bun. It adds a wonderful creaminess and healthy fats.
  5. Clever Toasting Hack for Buns: If you don’t have a cast-iron skillet or a griddle, you can still achieve wonderfully toasted buns. Simply place the split brioche buns, cut-side up, under your oven’s broiler for a few minutes. Keep a very close eye on them, as they can burn quickly!
  6. Effortless Baked Eggs for a Crowd: For a truly stress-free approach to preparing egg patties when feeding many people, generously grease a 12×8-inch baking pan (a brownie pan works perfectly). Pour in all of your whisked egg mixture (scaled up proportionally for your crowd), and bake it in a preheated oven at 350°F (175°C) for 15-20 minutes, or until the entire slab is set and lightly golden. Once cooled slightly, slice it into 6 (or more) neat squares for perfect, uniformly sized egg patties!
  7. Calabrian Mayo Flavor Alternatives: No Italian chili peppers on hand? No problem! You can still create a remarkably similar spicy and tangy flavor profile for your mayo. Try blending roasted red bell peppers with a dash of smoked paprika and a tiny pinch of cayenne pepper for heat. To truly mimic the essential tanginess of pickled peppers, add about 1 tablespoon of apple cider vinegar or fresh lemon juice to the pepper mixture before blending it smoothly with the mayonnaise.
  8. Healthy Bread Option: For those seeking a delicious whole grain alternative without sacrificing too much of the classic brioche character, keep an eye out for whole wheat brioche buns. Some specialty grocery stores or health-conscious bakeries, like Aldi, occasionally carry them, offering a healthier twist that’s still incredibly flavorful.
  9. Diverse Cheese Choices: While Swiss cheese is a fantastic recommendation for its mild, nutty flavor and excellent meltability, feel free to experiment with other melting cheeses. Provolone offers a sharp, tangy bite, cheddar provides a classic creamy richness, or for an extra kick, a spicy pepper jack can add a wonderful zing.
  10. Fresh Herb Enhancements: A sprinkle of freshly chopped chives, parsley, or even a touch of cilantro on your eggs or layered within the sandwich can add an extra burst of freshness and aromatic flavor, brightening the entire experience.
  11. Spice it Up with Hot Sauce: For those who crave even more heat, a few dashes of your favorite hot sauce directly onto the egg patty or mixed into the Calabrian mayo will certainly do the trick!

    6. Melt Cheese and Serve: Spread about 1 tablespoon of the chilled Calabrian mayo onto the top half of each brioche bun. Place one slice of Swiss cheese directly over the mayo. For perfectly melted, gooey cheese, microwave the top bun with the cheese for approximately 10 seconds on high power, or until the cheese is beautifully melted and warm. Carefully place this cheese-topped bun over your assembled sandwich. Serve your homemade bistro-style egg sandwich immediately and prepare to indulge!

Notes & Pro Tips

* For best results, use a good quality sunflower oil (or other neutral oil like canola) for cooking your eggs to ensure a pure, clean flavor without any interference.
* It’s important not to overcook your egg patties; they should remain wonderfully fluffy and tender, never rubbery.
* Feel free to adjust the amount of crushed Calabrian chili peppers in your mayo to perfectly suit your personal spice preference – less for mild, more for extra heat!
