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

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with nonstick spray or a light coat of olive oil.

Step 2

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.

Step 3

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.

Step 4

In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until fully combined.

Step 5

Stir in the cheddar cheese and parmesan cheese. If using bacon or sausage, fold that in as well.

Step 6

Add the sautéed spinach, onion, and bell pepper mixture to the egg mixture. Stir gently until everything is evenly distributed.

Step 7

Pour the mixture into the prepared baking dish, spreading it out evenly.

Step 8

Bake in the preheated oven for 35-40 minutes, or until the casserole is set in the center and the top is golden brown.

Step 9

Remove from the oven and allow the casserole to cool slightly for 5-10 minutes before slicing and serving.

Step 10

Serve warm and enjoy! Store any leftovers in the refrigerator for up to 4 days or freeze for up to 2 months.
