Recipe Information
Ingredients
- 8 large eggs
- 5 cups fresh spinach
- 1 cup milk
- 1 cup cheddar cheese, shredded
- 0.5 cup parmesan cheese, grated
- 1 medium onion, diced
- 1 medium bell pepper, diced
- 1 tablespoon olive oil
- 2 cloves minced garlic
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 1 cup optional: cooked and crumbled bacon or sausage
Instructions
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with nonstick spray or a light coat of olive oil.
Heat a large skillet over medium heat and add the olive oil. Sauté the diced onion and bell pepper for 4-5 minutes until softened.
Add the minced garlic and fresh spinach to the skillet. Cook for 2-3 minutes, stirring occasionally, until the spinach is wilted. Remove from heat and set aside.
In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until fully combined.
Stir in the cheddar cheese and parmesan cheese. If using bacon or sausage, fold that in as well.
Add the sautéed spinach, onion, and bell pepper mixture to the egg mixture. Stir gently until everything is evenly distributed.
Pour the mixture into the prepared baking dish, spreading it out evenly.
Bake in the preheated oven for 35-40 minutes, or until the casserole is set in the center and the top is golden brown.
Remove from the oven and allow the casserole to cool slightly for 5-10 minutes before slicing and serving.
Serve warm and enjoy! Store any leftovers in the refrigerator for up to 4 days or freeze for up to 2 months.
