Classic Breakfast Sausage and Egg Casserole
Description
The heart of the casserole is the egg mixture, made with eggs, milk (or heavy cream for a richer texture), salt, pepper, and seasonings like garlic powder or smoked paprika. Once mixed, it’s poured over the sausage and bread, ensuring every bite is packed with flavor. A generous layer of shredded cheese—cheddar, mozzarella, or pepper jack—melts beautifully on top, adding a creamy, gooey finish.
Baking the casserole at 350°F (175°C) for 30-40 minutes results in a golden-brown top with a soft yet sturdy interior. It’s important to let it rest for 5-10 minutes after baking to allow it to set before slicing. This casserole can be made the night before, stored in the fridge, and baked fresh in the morning for ultimate convenience.
Perfect on its own or served with fresh fruit, toast, or a side of crispy bacon, this Classic Breakfast Sausage and Egg Casserole is a comforting, crowd-pleasing dish that never disappoints.
