Notes

Make ahead: Assemble the casserole, cover, and refrigerate overnight. Bake fresh in the morning.
Swap cheddar with Swiss, Monterey Jack, or mozzarella.
Add veggies like bell peppers, mushrooms, or spinach for extra flavor.
Use croissants, bagels, or brioche instead of bread cubes for a richer version.
