This Egg White Omelet Checks Every Box
- Fresh and flavorful. This egg white omelet is packed with sautéed veggies like bell pepper, zucchini, and onion, bringing color and crunch to every bite. The egg whites keep it light, while the vegetables make it feel hearty and satisfying.
- A little fancy. There’s something about an omelet that feels special, like something you’d order at a cozy café or brunch spot. This version brings that same feeling to your own kitchen, no reservation needed.
- Quick and easy. Even though it looks like a weekend brunch dish, this omelet comes together fast with just a handful of ingredients.
Is it Omelet or Omelette?
You’ll see it spelled both ways, but here in the US, we stick with “omelet.” “Omelette” is the French spelling, and while it adds a little flair, the recipe stays the same: fluffy eggs stuffed with savory filling.
What You’ll Need
Here are the ingredients you’ll need to make this veggie and protein-filled breakfast omelet. Scroll to the recipe card at the bottom of the page to see the exact amounts for all the ingredients.
- Egg whites – You can use liquid egg whites from a carton or separate them yourself. Either works great.
- Sea salt & Black pepper – Make sure to use freshly ground black pepper.
- Avocado oil – Great for high-heat cooking. Olive oil works too if that’s what you have on hand.
- Onion – I like to use a yellow onion for this recipe, but white or red onions, or even shallots or scallions will also work.
- Red bell pepper – Adds color and a slight sweetness. Any color bell pepper works, or try poblano for a little kick.
- Zucchini – Yellow summer squash is an easy swap if that’s what you have.
- Garlic – You can also use garlic powder in a pinch.
- Bacon (optional) – Adds smoky, salty flavor. For best texture, cook it until crispy, then crumble it in.
- Parmesan (optional) – Or swap with cheddar, mozzarella, feta, or your favorite dairy-free cheese.
How to Make an Egg White Omelet
Here’s a quick look at how to make this 25-minute breakfast:
- Beat the eggs. Add the egg whites to a bowl with salt and pepper and whisk until frothy.
- Cook the onions and peppers. Heat the oil in a large skillet over medium-high heat. Add the onion and bell pepper and season with salt. Sauté until the ingredients are slightly soft, which should take about 3 minutes.
- Add the rest of the veggies. Put the zucchini and garlic in the skillet and sauté until slightly soft, about 3 minutes.
- Pour in the eggs. Add the egg mixture to the skillet and then tilt the pan to make sure that the eggs are evenly distributed throughout the pan.
- Cook. Lower the heat to low, and put a lid on the skillet. Cook until the egg whites are no longer translucent, which should take 3-5 minutes.
- Flip. Flip the omelet and cook for 1 more minute.
- Add the optional ingredients. If using, put the crumbled bacon and grated parmesan cheese on top of the omelet.
- Fold. Fold the omelet in half, so that it forms a perfect half-circle.
- Finish cooking and serve. If you’re using the optional bacon and parmesan cheese, then turn the heat off, put a lid on the skillet, and let the omelet rest until the cheese melts, about 1-2 minutes. If you’re not using the optional ingredients, then serve immediately.
Tips for The Perfect Omelet
- Use fresh egg whites when possible. Carton egg whites work just fine, but if you’re after the fluffiest texture and best flavor, separating whole eggs by hand gives you a little edge. Save the yolks for baking or whisk them into a scramble later.
- Don’t be afraid to mix up the veggies. This recipe is super flexible. Bell peppers and zucchini are a great base, but spinach, mushrooms, broccoli, kale, or even leftover roasted veggies all work beautifully. Just make sure to cook out any excess moisture so the omelet doesn’t get soggy.
- Master an easy flip. You’ve got two solid options: use two spatulas to flip gently in the pan, or place a plate over the skillet, invert the omelet onto the plate, then slide it back into the pan to finish cooking.
- Keep the heat low. Egg whites can overcook fast. Cooking over medium-low heat helps them stay soft and tender without drying out or turning rubbery.
How to Store and Reheat Leftovers
Leftover egg white omelets will last in the fridge for 3 days. Just make sure that you store the omelet in an airtight container. The texture of the omelet might be messed up when you reheat it, as eggs tend to get rubbery when reheated. But you can reheat the omelet in a microwave on 80% power in 15-second increments until it’s warm throughout.
