This quick and easy breakfast casserole is made with simple ingredients like sausage, eggs, bread, and cheese. It’s a crowd-pleaser that comes together in under 30 minutes, perfect for busy mornings or holiday brunches.
For best results, use day-old bread and let the casserole rest before slicing. To make ahead, assemble the night before and refrigerate; add 5-10 minutes to baking time. For a vegetarian version, swap sausage for plant-based sausage or black beans with sautéed mushrooms and bell peppers.
