Ingredients

• 8 large eggs
• 1 cup milk
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1 cup shredded cheddar cheese
• 1 cup cooked breakfast sausage
• 1 cup diced bell peppers
• 1 cup chopped spinach
• 0.5 cup diced onion
• 1 tablespoon olive oil
• 1.5 cup cooked and diced potatoes

Directions

Step 1

Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with cooking spray or butter.

Step 2

Heat the olive oil in a large skillet over medium heat. Add the diced onion and bell peppers, cooking until softened, about 5 minutes.

Step 3

Add the chopped spinach to the skillet and cook for another 2-3 minutes until wilted. Remove from heat and set aside.

Step 4

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

Step 5

Stir the shredded cheddar cheese, cooked breakfast sausage, cooked potatoes, and the cooked vegetables (onion, bell peppers, and spinach) into the egg mixture.

Step 6

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

Step 7

Bake in the preheated oven for 35-40 minutes, or until the top is golden and the center is set. You can insert a knife into the center; if it comes out clean, the casserole is done.

Step 8

Let the casserole rest for 5-10 minutes before serving. Slice into portions and enjoy!
