    Cinnamon sugar French Toast Casserole is the perfect breakfast for overnight guests or for a holiday brunch. It can be made ahead of time!

    delicious french toast casserole with maple syrup

    It’s always a joy to share a delicious breakfast with family or friends. What a great way to start the day! And one way to make it even more enjoyable is to prepare a simple, yet outstanding dish like a French toast bake and if you can assemble it ahead of time that is a bonus.

    cutting bread into small cubes

    Cut enough cubes of bread from a loaf of French or Italian bread to make 10 cups. I slightly less than one loaf of Italian bread.

    Spread the bread out in an even layer in a greased jelly roll pan. Set aside.

    mixing the eggs and milk with a whisk

    Whisk together the eggs, milk and salt.

    adding egg mixture to the cubed bread

    Pour the egg mixture over the bread cubes and place in the refrigerator for about 10 minutes to allow the egg mixture to absorb a bit.

    How can I make French toast casserole ahead of time?

    To make French toast casserole ahead of time, cut the bread and coat with the egg mixture. Cover the pan with plastic wrap and place it in the refrigerator overnight. Mix together the sugars and ground cinnamon in a ziptop bag and set it aside until morning. In the morning, remove the plastic wrap and continue with the recipe.

    adding butter and milk to the cinnamon sugar mixture

    Mix together the granulated sugar, brown sugar, and ground cinnamon. Stir in the melted butter, milk, and vanilla extract.

    adding the cinnamon sugar mixture to the bread cubes on the pan

    Remove the pan from the refrigerator and drizzle the sugar mixture over the bread.

    Bake the French toast casserole at 350˚F for 45-50 minutes, until cooked through and golden brown.
