  • Total Time: 30

Ingredients

Scale
  • 1 cup fresh spinach (chopped)
  • 1 cup mushrooms (sliced (cremini or button mushrooms recommended))
  • 1/2 cup onion (diced)
  • 1 cup egg whites (about 8 large egg whites)
  • 1/4 cup low-fat milk (optional for creaminess)
  • Salt and pepper (to taste)
  • 1 tablespoon olive oil
  • 1/4 cup shredded cheese (optional, for extra flavor)

Instructions

  • Preheat your oven to 375°F (190°C).
  • In a large oven-safe skillet, heat the olive oil over medium heat. Add diced onions and sauté for about 3-4 minutes until translucent.
  • Add the sliced mushrooms to the skillet and cook for another 5 minutes, until they release their moisture.
  • Stir in the chopped spinach and cook until wilted, about 1-2 minutes.
  • In a bowl, whisk the egg whites with milk, salt, and pepper. Pour the mixture over the sautéed vegetables in the skillet.
  • If using, sprinkle the cheese evenly on top.
  • Cook on the stove for 2-3 minutes until the edges begin to set, then transfer the skillet to the preheated oven.
  • Bake for 15-20 minutes, or until the frittata is set in the center. A toothpick inserted should come out clean.
  • Let it cool for a few minutes, slice, and enjoy!
