Ingredients for Breakfast Egg Bake Casserole
You’ll need the following ingredients for this breakfast casserole:
- Eggs: As you may have guessed, eggs are the star of this baked egg casserole.
- Sausage: To add a bit more protein, feel free to use pork sausage, turkey sausage, or chicken sausage. You can also use bacon or ham if you prefer.
- Potatoes: I’ve added potatoes directly into the casserole to make the dish more well-balanced overall. Any type of white potato will work.
- Bell Peppers: The recipe calls for one red bell pepper and one green bell pepper, but you can use any colors you have on hand.
- Onion: I used white onion, but you can use a yellow or red onion if needed.
- Cheese: Although optional, cheese helps to add a touch of protein, some healthy fats, and cheesy flavor. The recipe calls for sharp cheddar cheese, however, Swiss cheese, Monterey jack, and Colby jack cheese would all work well.
- Spices: A bit of dried oregano and red pepper flakes to enhance the flavor of the sausages.
- Salt and Pepper: To season the dish.
In addition to the above, I like to serve my egg bake with a sprinkle of chopped parsley and chopped green onion on top.
