A hearty and savory breakfast casserole that can be prepped the night before and baked in the morning, perfect for busy families and meal prep.
Letting the casserole soak overnight in the fridge ensures a custardy texture. Use day-old or lightly toasted bread cubes to prevent sogginess. If the top browns too quickly, tent with foil halfway through baking. Adjust baking time if using a different size dish.
