Egg White Frittata Recipe

Egg White Frittata Recipe

Plenty of vegetables, Parmesan cheese, and seasonings make this light and easy egg white frittata satisfying and delicious. You might think that it would be bland with just egg whites, but even without the yolks, the frittata is fluffy and flavorful. Plus, it is easy to adapt it with your favorite vegetables and seasonings.

As far as the ingredients go, a frittata is similar to an omelet, but there are a few differences. The frittata, which can serve several people, is partially cooked on the stovetop and finished in the oven. An omelet, typically designed for one or two people, is cooked only on the stovetop.

You may make our tasty egg white frittata with fresh or store-bought liquid egg whites. The egg mixture includes Parmesan cheese, green onions, diced bell pepper, spinach, and sliced grape tomatoes, along with a little Italian seasoning. You can swap out the Parmesan with some yellow cheddar for extra color or use Gruyere, Swiss, or another kind of cheese.

This egg white frittata goes exceptionally well with marinara sauce or prepared pizza sauce, or give it that extra pizzazz with a garnish of tomato salsa, sour cream, or sliced avocados. An egg white frittata makes an excellent breakfast, brunch, or lunch dish any day of the week.

“Quick and easy, this egg white frittata is just as satisfying as one made with whole eggs. Use carton whites to make this dish extra fast. The spinach, bell pepper, tomato, and cheese make it a flavorful recipe that’s easy to tweak to suit your tastes.” —Laurel Randolph

  • An oven-safe nonstick skillet is essential for a frittata. If you use cast iron, make sure it is well-seasoned. Eggs will likely stick to plain stainless steel unless you add an extra tablespoon or two of butter or oil—make sure the oil is hot when you add the eggs.
  • When it comes to cheese, don’t skimp. The cheese adds protein, flavor, and aids in browning.
  • Toppings and garnishes give an egg white frittata pizzazz! Serve your frittata with a few choices, such as marinara sauce, guacamole, sliced avocado, chopped green onions, tomato salsa, salsa verde, sour cream, chives, or fresh chopped parsley or cilantro.

Recipe Variations

  • Tex-Mex Egg White Frittata: Instead of Italian seasoning, add 3/4 teaspoon of chili powder and 1/4 teaspoon of garlic powder to the eggs along with the salt and pepper. Replace the Parmesan with about 1 cup of shredded cheese, such as a Mexican blend, Monterey Jack cheese, or pepper jack cheese. Garnish with salsa verde, avocado, sour cream, chopped cilantro, or tomato salsa.
  • Cheddar-Ham Egg White Frittata: Omit the grape tomatoes and replace the Parmesan cheese with sharp or mild shredded cheddar cheese. Sauté about 1/2 cup of diced ham, green onion, and red bell pepper. Add the spinach to the pan or omit it. Garnish with sour cream or ketchup, as desired.
  • Mushroom and Spinach Egg White Frittata: Omit the grape tomatoes and red bell pepper. Replace the Parmesan cheese with about 1 cup of shredded mozzarella or fontina cheese. Sauté 1 cup of sliced mushrooms with the green onions until they release their liquid. Add the spinach to the pan and cook until the spinach wilts. Continue to cook as directed. To finish, top with the sliced dark green onion tops and the remaining half of the cheese and bake as directed.
  • Broccoli-Cheddar Egg White Frittata: Omit the green onions and spinach. Replace the Parmesan with 3/4 to 1 cup of shredded cheddar cheese and sauté about 1/2 to 3/4 cup of chopped broccoli with the red bell pepper until tender. Continue cooking as directed and finish with the sliced grape tomatoes and the remaining shredded cheese.

How to Store and Freeze

  • This frittata can be stored in the fridge for up to 4 days, making it a perfect grab and go breakfast during the week.
  • You can also freeze frittatas. Cut the cooled frittata into individual slices, and place on a cookie sheet in the freezer. Once the slices are frozen, put them in an airtight container or zip-close freezer bag for up to 3 months.

What can I do with a carton of egg whites?

You can make egg white omelets or scrambled egg whites, or lighten your omelet or scrambled eggs with 1 whole egg and about 1/4 cup of liquid egg whites. Swedish sugared nuts are a tasty snack you can make with egg whites. Mini meatloaf muffins are made with egg whites, as is this spectacular Norwegian ring cake.

Why did my frittata puff up?

If the eggs are over-beaten, a frittata can expand and puff up, giving it a spongy texture. Beat the eggs lightly for the best texture.
