A simple, make-ahead breakfast casserole with savory sausage, creamy custard, and melty cheese. Perfect for feeding a crowd on holiday mornings or lazy weekends.
For best results, assemble the casserole the night before and refrigerate overnight. Shred your own cheese for smoother melting. Let the casserole rest after baking for easier slicing.
