An egg white frittata is a light, fluffy, protein-packed take on the classic Italian egg dish, using only egg whites instead of whole eggs, loaded with vegetables and a bit of cheese. It’s cooked partly on the stovetop and finished in the oven, making it easy to feed a group without flipping individual portions like an omelet.
Why Use Egg Whites
Egg whites are lower in calories and fat than whole eggs while still providing a good source of protein, making this a lighter option for anyone watching their intake without sacrificing a satisfying breakfast. The vegetables and a modest amount of cheese still give the dish plenty of flavor and texture.
Ingredients
- 2 cups liquid egg whites
- 1 tablespoon olive oil
- 1/2 cup diced bell pepper
- 1/2 cup sliced mushrooms
- 1/2 cup chopped spinach
- 1/4 cup diced red onion
- 1/2 cup cherry tomatoes, halved
- 1/4 cup shredded mozzarella or feta cheese
- 1/2 teaspoon garlic powder
- 1/2 teaspoon Italian seasoning
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- 2 tablespoons chopped fresh parsley
Instructions
1. Prepare the Vegetables
Preheat the oven to 375°F (190°C). Heat olive oil in an oven-safe nonstick skillet over medium heat. Add the onion, bell pepper, and mushrooms. Cook for 4–5 minutes until the vegetables begin to soften.
2. Add the Spinach and Tomatoes
Stir in the spinach and cherry tomatoes. Cook for another 1–2 minutes, just until the spinach wilts.
3. Season the Egg Whites
In a bowl, whisk the egg whites with garlic powder, Italian seasoning, salt, and black pepper until well combined.
4. Add the Egg Mixture
Pour the seasoned egg whites over the vegetables. Gently stir once to distribute everything evenly. Cook on the stovetop for about 2–3 minutes, without stirring further.
5. Add the Cheese
Sprinkle the mozzarella or feta evenly over the top.
6. Bake
Transfer the skillet to the preheated oven. Bake for 12–16 minutes, or until the center is set and the frittata looks lightly puffed.
7. Finish and Serve
Remove from the oven and let it rest for 3–5 minutes. Sprinkle with fresh parsley, slice into wedges, and serve warm.
Tips for the Best Egg White Frittata
- Don’t overcook the frittata, as egg whites can become rubbery when baked too long.
- Sauté watery vegetables first so excess moisture doesn’t make the frittata soggy.
- Try adding zucchini, broccoli, asparagus, or roasted red peppers for different flavors.
- Feta adds a salty, tangy flavor, while mozzarella creates a milder and creamier finish.
- For meal prep, refrigerate cooled slices in an airtight container for up to 3–4 days.
Storage
Store leftover frittata in an airtight container in the refrigerator for up to 4 days. Reheat individual slices in the microwave, or enjoy cold.
Final Thoughts
An egg white frittata is a simple, light way to start the day with plenty of protein and vegetables in every bite. It’s easy to customize based on what’s in the fridge, and it reheats well for quick breakfasts throughout the week.
