A simple and delicious make-ahead French toast casserole with cinnamon that soaks overnight for a custardy, soft center and crispy golden edges. Perfect for busy mornings and customizable with nuts, fruits, or dairy-free options.
Use day-old or slightly stale bread for best texture. Let the casserole soak overnight for full custard absorption. Dotting butter on top before baking creates golden, crispy pockets. Tent with foil if top browns too fast. Adjust milk or baking time if texture is too soft or dry. Can substitute gluten-free bread and plant-based milk for dietary needs.
