Can I make this an overnight brioche French toast?

Yes! In fact, allowing the dish to sit in the refrigerator makes sure the egg mixture is completely absorbed and it saves time in the morning if you assemble the Brioche Baked French Toast recipe the night before.     

How to make this Brioche Baked French Toast recipe

To make this baked French toast with brioche, start by greasing the bottom and sides of a 9″x9″ baking dish with nonstick cooking spray or butter. Place the brioche cubes in the pan and set aside.

In a medium bowl add eggs, milk, 1 teaspoon of the cinnamon, vanilla, and pinch of salt. Whisk together for at least a minute to add air to the mixture (whisking your eggs for 1-2 minutes ensures the mixture is evenly mixed and also adds air to help you achieve a light and airy bake for your Brioche Baked French Toast).

Pour the egg mixture over the brioche cubes and toss until all the cubes are coated with the egg mixture. Making sure all the bread cubes are coated with the egg mixture will ensure an even bake and that there are no dry cubes when serving. Cover the dish with foil and place it in the refrigerator for a few hours or overnight.

When you are ready to bake the Brioche Baked French Toast Casserole, pull the dish out of the refrigerator and let it sit at room temperature for about 30 minutes while doing the next recipe steps.

Preheat the oven to 350° F. In a small bowl add brown sugar, flour, and the remaining 2 teaspoons cinnamon and whisk together with a fork to break up the sugar and evenly distribute the flour and cinnamon.

Add the cold pieces of butter and press it into the mixture to create small pieces of crumble. Tip for a chunkier crumble topping: before adding the crumble to the top of the dish, squeeze it in your hand first so it sticks together, then break it up as you top the dish so you have bigger chunks on top.     

Add the crumble evenly over the top of the brioche cubes mixture, then re-cover with foil.

Bake the Brioche Baked French Toast in the oven for 20 minutes. Remove the foil and bake for an additional 10 minutes to allow the top to get golden brown. After removing it from the oven, let it sit for a few minutes so everything settles and the brioche French toast sets. 

The crumble topping just melts into the top of the breakfast bake for a delightful flavor and texture!

Serve the baked French toast with brioche bread hot with butter and syrup (or experiment with other toppings, such as creme Anglaise, or add some berries, chocolate chips, nuts, and/or whipped cream).

Baked brioche French toast is just next level, while being so easy to make!

You’ll want to make this overnight brioche French toast for every holiday weekend! It will become a tradition.

To reheat leftovers (if you have any), I like to spread butter on my brioche French toast first while it’s cold, then heat in the microwave for 30 seconds. Then I add whatever other toppings I want (syrup, creme Anglaise, etc.) and heat for another 15-20 seconds.
