A hearty, comforting breakfast casserole made with day-old bread, savory sausage, and sharp cheddar cheese, baked on a sheet pan for maximum crispiness and easy cleanup.
Use day-old bread to prevent a soggy texture. Let the casserole rest for 10 minutes after baking to allow the custard to set. Can be assembled the night before and refrigerated overnight.
