A simple, crowd-pleasing breakfast casserole made with breakfast sausage, eggs, milk, bread, and cheddar cheese. Perfect for busy mornings, potlucks, and make-ahead meals.
Use day-old bread for best texture; fresh bread can become mushy. For a make-ahead option, assemble the casserole the night before, cover with foil, and refrigerate. Let sit at room temperature for 30 minutes before baking, and add 5-10 minutes to the baking time. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To freeze, bake, cool completely, wrap tightly in plastic wrap and foil, and freeze for up to 2 months.
