Method
- Preheat the oven to 375°F (190°C).
- In a medium skillet, heat the olive oil or butter over medium heat. Add the onion, bell pepper, and mushrooms. Sauté until the vegetables are tender, about 5-7 minutes.
- Add the chopped spinach and cook for another 2 minutes until wilted.
- In a bowl, whisk together the eggs, salt, and pepper. Pour the eggs over the cooked vegetables in the skillet.
- If using cheese, sprinkle the mozzarella on top.
- Transfer the skillet to the preheated oven and bake for 10-15 minutes, or until the eggs are set and the top is lightly golden.
- Remove from the oven and let it cool for a few minutes before slicing.
- Serve warm and enjoy!
Notes
You can use any combination of vegetables in this recipe. Try adding zucchini, tomatoes, or broccoli for more variety.
For a lighter version, you can use egg whites instead of whole eggs or reduce the cheese to lower the calorie count.
To make the frittata ahead of time, cook it fully and store it in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
