Ingredients

  • Olive oil cooking spray can also use 1 tablespoon olive or other neutral oil
  • 1/2 cup yellow onion thinly sliced
  • 8 ounces mushrooms button or baby bella/cremini, stems removed and sliced
  • 1 to 2 tablespoons fresh herbs chives, thyme, rosemary, to taste
  • 2 cups baby spinach tough or long stems removed
  • Kosher salt to taste
  • Fresh ground black pepper to taste
  • 1 1/2 cups egg whites
  • 1 large egg beaten (optional - for color)
  • 2 to 3 tablespoons crumbled goat cheese

Instructions

  • Preheat the broiler with an oven rack 5 to 6 inches away from the heating element.
  • Heavily coat the bottom of a cast iron skillet (or other oven-safe skillet) with olive oil spray and heat over medium heat. Add the onion and cook until starting to wilt.
  • Stir in the mushrooms and cook, stirring occasionally, until the mushrooms are cooked through and soft.
  • Reduce heat to medium-low and stir in the spinach, a handful at a time. Cook, stirring constantly, until the spinach wilts and the moisture is cooked off. Sprinkle with the chopped herbs; season with salt and pepper.
  • Whisk together the egg whites and egg; pour over top of vegetables in skillet. Cook until the egg is set on the bottom and starting to cook on the sides; they should still be slightly runny on top. Sprinkle with goat cheese. Place skillet under the broiler and cook until the egg is set and the frittata is lightly browned in places.
  • Remove from oven and let sit for 2 to 3 minutes. Season with ground pepper, cut into wedges and serve.
