Why You’ll Love This Healthy Omelet

I make this recipe all the time for breakfast (and sometimes for lunch or dinner, too!). Here are a few reasons why it really stands out in my eyes. 

  • Super healthy. Egg whites are an incredibly healthy ingredient. They have so much protein, but they’re way lower in cholesterol than whole eggs. They’re really one of the best breakfast foods that you can eat. But this dish is also loaded with fresh veggies, with large amounts of bell pepper, zucchini, and onion. It’s a fresh, protein-packed, low-carb breakfast. 
  • Fancy. Most people associate omelets with fancy buffets and nice breakfast joints. Omelets just feel like a fancy and indulgent breakfast. This egg white omelet is no exception. You’ll feel like you’re out for an upscale brunch when you eat this, even if it’s just a Tuesday morning at home.
  • Easy. Even though this recipe looks and tastes fancy, it’s very easy to make. It’s a simple and straightforward recipe, made mostly with foods that you probably already have around the house. And it only takes 25 minutes to make!

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
  • Sea salt
  • Black pepper – Make sure to use freshly ground black pepper.
  • Avocado oil
  • 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
  • Zucchini
  • Garlic
  • Bacon – This is an optional ingredient, but be sure to use super crispy bacon if you include it.
  • Parmesan – The cheese is also optional.

How to Make This Egg White Omelet

Here’s 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.

  • 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 Success

Here are a few tricks and tips that you can use when you make this egg white omelet. 

  • Use real eggs. You can use pre-packaged cartons of egg whites for this recipe if you want. But you’ll always get the best results if you use fresh eggs, and separate the whites. Just remember to hold onto the egg yolks so you can use them in a different recipe! 
  • Add more veggies. This is a great recipe to help you use up some of the veggies that are in the back of your fridge. Even though the recipe calls for zucchini and bell pepper, you can use almost any type of vegetable, from broccoli, to spinach, to mushrooms. 
  • Learn how to flip the omelet. There are two easy ways to flip this egg white omelet. The first is to use two spatulas and give it a quick flip. The second way is to place a plate or cutting board on top of the skillet and turn it upside down. Then you can slide the omelet back into the skillet.

What to Serve It With

Since this is one of my favorite breakfast foods, it’s only right to serve it with some other great breakfast foods and drinks. Here are some of my favorites.

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. 

Can I Freeze This Recipe?

I don’t recommend freezing this breakfast. Eggs do not do well being frozen and thawed after they’ve been cooked.
