This Easy Cheesy Sausage Breakfast Casserole is a simple, make-ahead dish perfect for busy mornings, holiday brunches, or last-minute potlucks. With savory sausage, melty cheese, and a soft custard, it’s a crowd-pleaser that comes together in minutes.
For best texture, use day-old bread and let the casserole rest before baking. Shred your own cheese for smoother melting. To make ahead, assemble the night before and refrigerate; add 10-15 minutes to baking time if starting cold.
