This easy make-ahead breakfast casserole with sausage is the perfect stress-free morning meal. Assemble it the night before, pop it in the fridge, and bake it fresh in the morning for a tender, cheesy, and deeply satisfying dish.
For best results, use day-old or slightly stale bread. Let the assembled casserole rest at least 20 minutes before baking if not making ahead. Internal temperature should reach 160°F to 165°F. Leftovers keep in the refrigerator for up to 4 days. The casserole can be frozen unbaked for up to 3 months.
