How To Make Overnight French Toast
One of the best things about this breakfast casserole is how easy it is to make – it only takes minutes! Here’s how to do it:
- Arrange your bread slices in a prepared 9×13.
- In a medium bowl, whisk together eggs, half & half, milk, vanilla and spices. Pour the mixture over the slices making sure all of them are coated well.
- Refrigerate overnight or for at least 4 hours before baking.
- When ready to bake, combine the topping ingredients and spread over the top. Bake at 350 for 35-40 minutes.

Ingredients
- 1 loaf french bread or thick texas toast
- 8 eggs
- 2 cups half and half
- 1/2 cup milk
- 3 Tbsp granulated sugar
- 1 1/2 teaspoons pure vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1/2 teaspoon salt
Cinnamon Crunch Topping
- 1 1/2 sticks butter softened
- 1 cup light brown sugar packed
- 1 Tbsp light corn syrup optional
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
Instructions
- Prepare a 9"x13" baking dish by coating the entire inside of the dish with butter or cooking spray. Set aside.
- Slice the French bread, about 1-inch thick. Arrange slices in your prepared baking dish in rows, overlapping the slices. Set aside.
- In a large bowl, whisk eggs. Add half-and-half, milk, sugar, vanilla, cinnamon, nutmeg, and salt. Whisk until well combined.
- Pour the egg mixture over the bread slices, making sure they are covered evenly. Spoon some of the mixture in between the slices making sure all the slices are completely covered. Cover with foil and refrigerate overnight.
- The next day, preheat oven to 350°F. Meanwhile, carefully flip each piece of bread over to make sure everything is nice and coated with the mixture.
Make the Topping
- Combine all ingredients in a medium bowl and mix to combine. Spoon the topping on top of the prepared bread slices. Then spread evenly over the bread (like you are icing a cake). You can also spread some of the mixture in between the slices to make sure the entire slice is covered (if you prefer).
- Bake for 35-40 minutes (no need to cover with foil), until puffed and lightly golden.
