This is the ultimate crowd-pleasing breakfast casserole, perfect for lazy weekends or feeding guests. It combines crispy hash browns, savory bacon, and a rich, cheesy egg custard all baked into one comforting dish. Assemble it ahead for a stress-free morning meal that everyone will love.
Thaw hash browns completely to avoid a watery casserole. Letting the baked casserole rest is crucial for clean slices. For a make-ahead option, assemble, cover, and refrigerate overnight, then bake adding 5-10 minutes. Swap bacon for breakfast sausage for a delicious variation.
