Ingredients

The following ingredients have 4 Servings
  • 1 tablespoon butter (for the skillet)
  • 8 large egg whites
  • 1/2 teaspoon Diamond Crystal kosher salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • 1/4 cup grated Parmesan
  • 1/3 cup cherry tomatoes (halved)
  • 1/4 cup chopped scallions

Instruction

  • Preheat your oven to 400 degrees F. Grease an 8-inch oven-safe skillet (such as a cast iron skillet) with butter.
  • Whisk the egg whites with salt, pepper, and garlic powder until foamy. Add the Parmesan and whisk to incorporate.
  • Heat the skillet over medium heat, about 3 minutes. Pour the egg mixture into the warm skillet. Allow it to cook for about a minute.
  • Arrange the tomatoes and scallions on top of the eggs. Keep cooking until the bottom is set, about 2 more minutes, then transfer the skillet to the oven to finish cooking for about 10 more minutes. The frittata is done when puffy and golden and a toothpick inserted in its center comes out clean.
  • Carefully loosen the edges of the frittata with a spatula, slice and serve.
