Ingredients
- 1 small onion
- 2 tomatoes
- 1 cup bell pepper (green or red)
- 1 cup fresh spinach
- 10 eggs
- 1 teaspoon salt
- 1/2 teaspoon pepper
- 1 1/2 cups shredded cheddar cheese
- 3 tablespoons milk (optional)
Step 1: Preheat the Oven and Prepare the Casserole Pan
Preheat your oven to 375°F.
While the oven is heating, grease a casserole pan with butter or olive oil to ensure the casserole doesn’t stick to the pan.
Step 2: Dice the Vegetables
Dice the onions, peppers, tomatoes, and spinach into small, bite-sized pieces.
Ensure all the vegetables are evenly chopped for a consistent bake.
Step 3: Combine Ingredients
In a large mixing bowl, combine the diced peppers, onions, tomatoes, spinach, eggs, salt, pepper, milk, and 1 cup of cheddar cheese.
Mix everything together well to ensure an even distribution of all ingredients.
Step 4: Assemble the Casserole
Pour the mixed ingredients into the greased casserole pan, spreading them out evenly.
Top the mixture with the remaining 1/2 cup of cheddar cheese to add a delicious cheesy layer.
Step 5: Bake the Casserole
Bake the casserole in the preheated oven for 35 minutes or until the center is firm and set.
You can check for doneness by inserting a knife or toothpick into the center; it should come out clean.
Step 6: Optional Toppings and Serve
Once the casserole is baked, you can add additional fresh tomatoes and more cheese on top if desired.
Let it cool slightly before serving.
Enjoy your delicious and nutritious breakfast casserole!
