Key Ingredients
This egg white breakfast sandwich combines fluffy egg whites, melted cheese, creamy avocado, and spicy garlic mayo on a toasted English muffin for a balanced breakfast with fresh flavor and satisfying texture.
Base & Structure — A toasted English muffin provides a crisp exterior and soft interior that holds the sandwich together while adding light crunch and texture.
Protein & Texture — Egg whites create a lighter, high-protein filling with a soft and fluffy texture when cooked gently. Whole milk or water helps loosen the eggs slightly so they stay tender instead of becoming dense or rubbery.
Richness & Cheese — Butter helps prevent sticking while adding subtle richness to the eggs. Cheddar cheese melts smoothly into the egg whites and helps bind the sandwich together, whether using sharp, medium, mild, or pepper jack for extra heat.
Seasoning & Flavor — Salt enhances the flavor of the egg whites without overpowering them, while black pepper adds mild warmth and depth.
Creaminess & Balance — Spicy garlic mayo adds creamy texture along with savory garlic flavor and gentle heat that gives the sandwich more character. Avocado adds cool creaminess that balances the spice and rounds out the overall texture.
Fresh Finish — Fresh cilantro adds brightness and a clean herbal finish that complements the richness of the cheese and avocado.
How to Make This Sandwich
Step 1 — Whisk the egg whites
In a small bowl, whisk together the egg whites, milk, salt, and pepper until slightly frothy.
Step 2 — Cook the egg round
Heat a nonstick skillet over medium-low heat and lightly grease a ring mold with butter. Set the mold in the pan, add the egg mixture, cover, and cook until mostly set.
Step 3 — Remove mold
Run a small rubber spatula around the interior of the ring mold to separate the egg, and carefully lift the mold with tongs.
Step 4 — Flip and melt the cheese
Flip the egg and top it with cheese. Cover and cook until the cheese melts and the egg is fully set.
Step 5 — Toast the muffin
While the egg finishes cooking, toast the English muffin until golden and lightly crisp.
Step 6 — Assemble the sandwich
Spread spicy garlic mayo on the English muffin, add the egg round, and top with avocado and cilantro.

Useful Tips
- Keep the heat low – around 3 on your stovetop dial. This is the difference between fluffy and rubbery eggs.
- Grease the ring mold well – it makes removal clean and easy.
- Cover with a lid – the retained heat will allow for even cooking and quick melting cheese.
- Use tongs to remove the ring mold – it will be hot, so under no circucmstances should you use your hands!
Egg White Breakfast Sandwich with Avocado
Equipment
- Nonstick skillet with lid
- Round ring mold
- Tongs
- Spatula
- Mixing bowl
- Whisk
Ingredients
- 1 English muffin
- 3 large egg whites
- 1 tbsp whole milk (sub water or milk of your choice)
- ½ tbsp unsalted butter
- Salt, a pinch
- Black pepper, a pinch
- 1 slice cheddar cheese
- 2 tbsp spicy garlic mayo
- ½ ripe avocado, sliced
- 1 tbsp fresh cilantro leaves
Directions
- In a small bowl, whisk together the egg whites, milk, salt, and pepper until slightly frothy, about 20 to 30 seconds.
- Heat a nonstick skillet over medium-low heat. Lightly grease the inside of a ring mold with butter and place the mold in the skillet.
- Pour the egg mixture into the ring mold, cover the skillet, and cook for about 10 minutes, or until the egg is mostly set on top.
- Carefully run a small spatula around the inside edge of the mold to release the egg, then remove the mold with tongs.
- Flip the egg round, place the cheese on top, cover the skillet, and cook for 1 to 2 minutes more, until the cheese is melted and the egg is fully cooked.
- While the egg cooks, toast the English muffin until golden and lightly crisp.
- Spread spicy garlic mayo on both halves of the muffin. Place the egg round on the bottom half, top with sliced avocado and cilantro, then close the sandwich.
Notes
- Cooking the egg whites over medium-low heat helps keep them soft and fluffy instead of rubbery or dry.
- Lightly greasing the ring mold prevents sticking and helps create a perfectly round egg for the English muffin.
- Keep the skillet covered while the eggs cook so the steam gently sets the top without overcooking the bottom.
- Toasting the English muffin adds structure and prevents the sandwich from becoming soft once assembled.
- For the cleanest layers and best texture, slice the avocado thinly just before assembling the sandwich.
- Remove the ring mold with tongs or a towel, as it will be very hot after cooking.
Variations and Substitutions
- Make it spicy – Swap the cheddar for pepper jack, add hot sauce, or use chipotle mayo for a smokier, spicier version.
- Add more protein – Turkey bacon or chicken sausage make great additions if you want a heartier, more filling breakfast sandwich.
- Make it dairy-free – Use water or unsweetened almond milk in the egg whites and either skip the cheese or use your favorite dairy-free alternative.
- Switch the bread – Bagel thins, sourdough, or even a croissant all work well depending on the texture and flavor you prefer.
- Swap the herbs – Fresh chives or green onions can be used instead of cilantro for a milder onion flavor.
Storage and Reheating
This sandwich is best enjoyed fresh while the egg is soft, the cheese is melted, and the English muffin is lightly crisp.
- Store the cooked egg and English muffin separately in the refrigerator for up to 2 days. Keep toppings like avocado and cilantro fresh until serving.
- To reheat, warm the egg gently in a skillet over low heat or microwave in short intervals until heated through, then toast the English muffin fresh before assembling.
- The egg and English muffin can also be frozen separately for up to 2 months for meal prep. Thaw overnight in the refrigerator, then reheat and assemble with fresh toppings.
- Avoid storing the fully assembled sandwich, as the avocado and sauces will soften the muffin and affect texture.
Frequently Asked Questions
Can I use liquid egg whites instead of fresh egg whites?
Yes, liquid egg whites work well for this sandwich. Use about ⅓ cup to replace the egg whites in the recipe and cook them the same way until set.
Why are my egg whites rubbery?
Egg whites can become rubbery if cooked over heat that is too high or for too long. Cooking them gently over low to medium-low heat and covering the pan briefly helps keep them soft and tender.
Do I need a ring mold for an egg white sandwich?
No, a ring mold is optional, but it helps create a thick, round egg shape that fits neatly on an English muffin. A small skillet or folded egg whites also work well if you do not have one.
Can this egg white breakfast sandwich be made ahead of time?
Yes, the cooked egg whites can be made ahead and refrigerated until ready to use. For the best texture, toast the English muffin and assemble the sandwich fresh before serving.
Are egg white breakfast sandwiches healthy?
Egg white breakfast sandwiches are generally lighter and higher in protein than traditional breakfast sandwiches made with whole eggs and heavier meats. Ingredients like avocado and fresh vegetables can also add healthy fats and freshness.
