French Toast Bake, also known as overnight French Toast Casserole, is a delicious breakfast dish that's perfect for feeding a crowd. It's made with a few simple ingredients, including bread (brioche, challah or French bread), eggs, half and half, sugar, and spices. To make the dish, the bread is usually cubed and placed in a baking dish. The egg mixture, which is made by whisking together eggs, milk or cream, sugar, and spices, is then poured over the bread. The casserole is usually left to sit overnight, allowing the bread to soak up the custard mixture. In the morning, the casserole is baked in the oven until it's golden and crispy on top. French toast bake can be served with a variety of toppings, such as fresh fruit, syrup, cinnamon or whipped cream.
