- 8 large eggs
- 1 cup milk (dairy or non-dairy)
- 1 tbsp olive oil
- 1 cup diced bell peppers (mixed colors)
- 1 cup chopped spinach
- 1 cup mushrooms (sliced)
- 1 small onion (diced)
- 0.5 cup shredded cheddar cheese
- 0.5 cup crumbled feta cheese
- Salt and pepper to taste
- Fresh parsley, chopped (for garnish)
- Additional shredded cheese (cheddar or mozzarella (Optional))
- 1 Preheat the Oven
Preheat your oven to 180°C (350°F). Lightly grease a 9x13-inch baking dish with cooking spray or a small amount of olive oil to prevent sticking.
- 2 Sauté the Vegetables
Heat olive oil in a large skillet over medium heat. Add diced bell peppers, onions, and sliced mushrooms. Sauté for about 5 minutes, or until the vegetables are soft and slightly caramelized. Add spinach and cook until wilted. Remove from heat and set aside.
- 3 Prepare the Egg Mixture
In a large bowl, whisk together eggs, milk, salt, and pepper until well combined. Stir in the sautéed vegetables and both cheeses. Pour the mixture into the prepared baking dish.
- 4 Bake the Casserole
Place the baking dish in the oven and bake for 40-45 minutes or until the casserole is set and lightly golden on top. A knife inserted into the center should come out clean.
- 5 Rest and Serve
Once baked, remove the casserole from the oven and let it rest for 5 minutes before slicing into portions. Garnish with freshly chopped parsley.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days. You can also freeze the casserole for up to 3 months. Just reheat in the oven or microwave.
- Variations: Customize the casserole with other vegetables like zucchini, broccoli, or tomatoes. You can also add cooked bacon or sausage for extra protein.
