This easy breakfast casserole features savory sausage, crispy frozen hash browns, and melted cheddar cheese in a rich egg custard. Perfect for holidays, weekends, and feeding a crowd with minimal effort.
Do not thaw the hash browns; use them frozen for the best texture. Let the assembled casserole rest before baking to ensure even cooking. For make-ahead, assemble the night before and refrigerate; add 10-15 minutes to baking time. For extra crispy edges, brush exposed hash browns with melted butter before baking.
