For an even richer flavor, use brioche bread instead of challah. You can also add other spices like nutmeg or allspice. Make this ahead of time! Assemble the casserole the night before and bake it in the morning. This allows the bread to fully absorb the custard mixture, resulting in a more tender and flavorful casserole.
