Breakfast casserole is a dish that can be made by combining a variety of ingredients,
such as eggs, potatoes, sausage, bacon, vegetables, and cheese, and baking them in a casserole dish. The ingredients can be mixed together in a bowl and poured into the dish, or they can be layered in the dish. The casserole is then baked in the oven until the eggs are cooked and the other ingredients are heated through. Breakfast casseroles are a convenient option for feeding a large group of people, as they can be made ahead of time and reheated for serving. They are also a good way to use up leftover ingredients, as almost any type of food can be added to a breakfast casserole.
