Method
Preparation
- Preheat your oven to 425° F and spray a quarter sheet pan with cooking spray.
- In a large bowl, whisk together the eggs, egg whites, 1/2 teaspoon of Italian seasoning, and a generous pinch of salt and pepper until well combined.
Cooking
- Heat olive oil in a large skillet over medium-high heat. Add the diced onion, sliced mushrooms, bell pepper, remaining Italian seasoning, garlic powder, salt, and pepper. Sauté for 3-5 minutes until the vegetables soften.
- Pour the sautéed vegetables onto the sheet pan and spread into a single layer. Gently pour the whisked egg mixture evenly over the vegetables.
- Bake in the preheated oven for 8-9 minutes, or until mostly set.
- Switch the oven setting to broil, spread marinara sauce over the top, layer on pepperoni and mozzarella, and broil for 2 minutes until cheese is melted and bubbly.
Serving
- Remove from oven, garnish with fresh basil, cut into slices and serve warm.
Notes
Customize the frittata with leftover vegetables or meats. For a spicier kick, add sliced jalapeños or red pepper flakes. Let cool slightly before slicing for better shape.
