Cinnamon French Toast Casserole

This French toast casserole is my secret weapon for holiday mornings when I want something impressive without the stress. You assemble it the night before, refrigerate it, and simply pop it in the oven while you brew your coffee. The custard soaks into every piece of bread overnight, creating an incredibly rich, creamy interior with a lightly crisp top. Served with maple syrup and fresh berries, it never fails to wow a crowd.
