High-Protein Egg White Omelette with Spinach
This egg white omelette is a filling, high-protein breakfast that comes together in about 10 minutes. It uses one whole egg plus egg whites for a fluffy texture and roughly 20 grams of protein, and it cooks in a single pan with very little cleanup. It works well on busy mornings, and it’s easy to adjust with whatever vegetables you have on hand.
Egg whites on their own can turn rubbery or bland. This version avoids that with a single whole egg for richness, a pan that’s hot but not too hot, and a little feta for flavor.
Why You’ll Love This Egg White Omelette
- High in protein: about 20g per serving (estimate).
- Fast: 10 minutes from fridge to plate.
- Affordable: everyday ingredients, no special products.
- Flexible: swap in whatever vegetables you have.
Ingredient Notes
- Eggs: 1 whole egg plus 3 egg whites. The yolk keeps the omelette tender. If you use liquid egg whites from a carton, measure about ¼ cup plus 2 tablespoons for 3 whites.
- Spinach: fresh baby spinach wilts in seconds. Frozen works too, but thaw it and squeeze out the water first, or the omelette turns soggy.
- Tomato: dice it small and pat it dry so it doesn’t release extra water.
- Feta: adds saltiness, so you need very little added salt. Skip it or use low-fat mozzarella if you prefer.
- Oil: use a small amount of olive oil or cooking spray, just enough to keep the eggs from sticking. A non-stick pan makes folding much easier.
Tips for a Fluffy Omelette
- Don’t over-whisk. Combine the eggs until uniform, then stop.
- Use a non-stick pan and a silicone spatula for easy folding.
- Pat wet vegetables dry. Extra water makes the omelette soggy.
- Keep the heat at medium. High heat makes egg whites tough and rubbery.
- Take it off the heat while the top is still slightly glossy. It finishes cooking on the plate.
Why Use Egg Whites?
Egg whites are almost pure protein, with very little fat, which is why they’re popular in high-protein breakfasts. Using them alone can taste flat, so this recipe keeps one whole egg for flavor and a softer texture. The result is lighter than a regular omelette and still satisfying. If you prefer a richer omelette, you can use two whole eggs and one white instead. Adjust the mix to suit your taste and your protein goals.
What to Serve With It
- A slice of whole-grain toast
- Sliced avocado or cucumber
- A small bowl of fruit or Greek yogurt for extra protein
Variations
- Mushroom and onion: cook 2 tablespoons of each before adding the eggs.
- Extra protein: add 2 tablespoons of cottage cheese to the egg mixture.
- Spicy version: add sliced green chili and a pinch of cumin.
- Dairy-free: skip the feta and add a squeeze of lemon juice.
Storage and Reheating
Omelettes are best fresh. If you have leftovers, refrigerate them in an airtight container for up to 2 days and reheat in the microwave for 30 to 40 seconds. The texture will be slightly firmer.
Frequently Asked Questions
How many egg whites equal one egg?
Two egg whites replace one whole egg in most recipes.
Why is my egg white omelette rubbery?

Can I use liquid egg whites from a carton?
Yes. Use about 2 tablespoons for each egg white.
Is this good for meal prep?
It’s best fresh, but leftovers keep in the fridge for up to 2 days and reheat quickly in the microwave.

Ingredients
Method
- Whisk the egg and egg whites with a small pinch of salt and pepper until combined and slightly frothy.
- Heat the olive oil in a non-stick pan over medium heat.
- Add the spinach and tomato and cook for 1 minute, until the spinach wilts. Push them to one side.
- Pour in the eggs. Let them set for about 30 seconds, then gently pull the edges toward the center, tilting the pan so uncooked egg runs underneath.
- When the top is mostly set but still slightly glossy (2 to 3 minutes), sprinkle the feta over one half.
- Fold the omelette in half, cook 30 seconds more, and slide onto a plate.
