This easy breakfast casserole features crispy hash browns, savory sausage, and melty cheddar cheese for a crowd-pleasing dish that’s perfect for holiday mornings or lazy weekends. Prep it the night before for a stress-free brunch.
The hash brown squeeze is not optional—excess moisture makes the casserole watery. Let the eggs come to room temperature if possible for even baking. Don’t overmix the egg mixture to avoid a rubbery texture. Let the casserole rest for 10 minutes before serving for cleaner slices. For a make-ahead option, assemble up to 24 hours in advance and refrigerate, then add 10-15 minutes to the baking time.
