This quick and easy breakfast casserole combines savory sausage, gooey cheddar cheese, and custard-soaked bread in one pan for a hearty, crowd-pleasing meal that comes together in under 40 minutes.
For best texture, use day-old bread. If using fresh bread, toast cubes first. Let the casserole rest 5 minutes after baking to set. To make ahead, assemble through step 6, cover, and refrigerate overnight; add cheese and bake in the morning, adding 5-10 minutes to baking time. Leftovers keep in the refrigerator for up to 4 days or freeze for up to 3 months.
