A quick and easy breakfast casserole featuring everything bagels, eggs, and a blend of cheddar and mozzarella cheeses, perfect for busy mornings or weekend brunch.
Let the bagel cubes soak in the egg mixture for at least 5 minutes before baking to ensure a moist, creamy center. Butter the baking dish well to prevent sticking. If the top browns too quickly, tent with foil halfway through baking. This casserole can be assembled the night before and baked fresh in the morning.
