Recipe Information
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
Instructions
Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with cooking spray or butter.
Heat the olive oil in a large skillet over medium heat. Add the diced onion and bell peppers, cooking until softened, about 5 minutes.
Add the chopped spinach to the skillet and cook for another 2-3 minutes until wilted. Remove from heat and set aside.
In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until well combined.
Stir the shredded cheddar cheese, cooked breakfast sausage, cooked potatoes, and the cooked vegetables (onion, bell peppers, and spinach) into the egg mixture.
Pour the mixture into the prepared baking dish, spreading out the ingredients evenly.
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.
Let the casserole rest for 5-10 minutes before serving. Slice into portions and enjoy!
