This recipe tastes just like French toast but can easily be made ahead so you can focus on the rest of the dishes for your special breakfast! It can even be made the night before and baked the next morning for a super easy brioche casserole!

Honestly, it’s so much easier than making regular French toast, and the custard mixture gives the brioche pieces the most wonderful texture and flavor. Your whole family will love this special bake!

What is Brioche French Toast Casserole?

Like regular French toast, this French toast casserole with brioche bread starts with the same ingredients: fresh bread, eggs, milk, vanilla, cinnamon, etc. Instead of dipping each of the bread slices into the egg mixture and griddling them, we dice them into cubes and toss them in the egg mixture before baking them in a casserole dish.

There, the ingredients meld together. The inside of the bites as tender and moist and the tops are crunchy and flavorful thanks to the sugar topping!


  • So easy: To make this overnight French toast casserole with brioche, you just need to cut the challah bread into 1-inch cubes, whisk together the egg mixture, then pour it over the bread. Pop it in the oven and serve! You’ll have plenty of time to work on other things while this dish is in the oven.
  • Absolutely delicious: Tender, sweet, and full of flavor, brioche bread is the perfect bread to take this baked French toast casserole to the next level! It’s luxurious and can be doctored with your favorite toppings.
  • Perfect for special occasions: Since brioche is so luxurious and special, we like to save this easy French toast bake for a special occasion or event, like a baby shower, Mother’s Day, Christmas morning breakfast, Easter morning, or other events.

Equipment

You really don’t need anything special for this brioche bread french toast casserole! You’ll need:

  • 9 x 13 baking dish

  • Small mixing bowl and whisk

Ingredients for Brioche French Toast Bake

For the French toast bake with brioche:

  • Brioche: Slice your loaf of brioche bread or challah into 1 inch cubes. Stale bread is the best!
  • Eggs: As the base of the custard, you’ll want to thoroughly whisk together your eggs before adding the other ingredients.
  • Milk: To rehydrate the bread cubes, you’ll need to add milk. I prefer to use organic whole milk when possible.
  • Heavy cream: To make this French toast brioche bake even more decadent, supplement the whole milk with fresh cream.
  • Vanilla extract: Vanilla is a key ingredient in the traditional French toast recipe, so it’s key in this overnight brioche French toast casserole too.
  • Maple syrup: Although you don’t need to sweeten the egg mixture, I prefer to add a little bit to the French toast casserole and enjoy it with fresh berries for a mild sweetness.
  • Cinnamon: Cinnamon really tastes wonderful in classic French toast! Feel free to swap it out with different warming spices to change your flavor profile.
  • Kosher salt: A pinch of salt will help highlight the sweet flavor in this French toast breakfast bake, so don’t skip it!

For the topping:

  • Butter: To get a crispy, crunchy bite on top of each bite, add small cubes of unsalted butter over the top.
  • Demerara sugar: This sugar has larger crystals and adds a fantastic crunch when baked with a little butter. Feel free to use brown sugar instead

Storing

Store leftovers in an airtight container in the fridge for 3-4 days. To reheat, you can either microwave your leftovers or pop a serving back in a hot oven (350 F oven) to get a nice texture on top.

Serving Suggestions

There are so many fun ways to serve this easy French toast casserole! At the simplest level, you can top it with a little powdered sugar or maple syrup and enjoy it with some scrambled eggs or bacon.

Since it’s subtly sweetened with maple syrup and crunchy sugar topping, I prefer to eat it with a bunch of fresh fruit and berries and a nice, strong cup of coffee. So good!

  • Whipped cream
  • Syrup
  • Berries and fresh fruit
  • Chopped nuts
  • Pie filling
  • Chocolate chips

Tips for Success

  • Be sure to let this French toast casserole brioche rest for a minimum of 30 minutes before baking.
  • To make this overnight brioche french toast bake, make the recipe following the instructions like normal. Then, stick the baking dish in the fridge covered in aluminum foil or a plastic wrap alternative. Just before baking, top with the butter pieces and sugar.
  • Tweak the seasonings to make this French toast casserole recipe your own! Replace vanilla extract with cardamom extract or cinnamon extract, etc. Instead of cinnamon, use Chinese five spice or apple pie spice!
  • Prefer to make this in individual servings? Butter some ramekins and bake them until fully cooked (165 degrees F).
  • Instead of cubes, you can cut the loaf of bread into slices and layer them together. 
  • The best French toast comes from stale bread. Make any bread “stale” by baking the cubes on a baking sheet at 350 degrees for 10-20 minutes, stirring halfway.
  • No brioche? Try French bread, sourdough, or really almost any other type of bread. To highlight the flavors in the custard, stick with a neutral-tasting bread.
  • Feel free to skip the cream and use half and half or more whole milk.
  • To make it easier to toss the brioche cubes in the mixture of milk and egg, you can add everything to a large mixing bowl, stir, then place it all in the casserole dish

Variations

  • Lemon Blueberry French Toast Bake: Replace the vanilla with lemon extract, add the zest of 1-2 lemons, and add up to 1 cup of fresh blueberries. Yum!
  • Apple Cinnamon French Toast Casserole: Add 2-3 diced tart apples and double the cinnamon. You can even use cinnamon extract! 
  • Raspberry Chocolate Baked French Toast: Mix 1/2 cup of chocolate chips and 3/4 cup of fresh raspberries before baking this easy breakfast casserole.

FAQs

Can you use brioche bread for French toast casserole?

Absolutely! Brioche is a fantastic type of bread for French toast casserole, as it’s naturally tender and flavorful.

Can you make brioche French toast casserole not overnight?

Yes! It does really help to let the casserole soak for a while, but you definitely don’t need to wait overnight. Give it at least 30 minutes to an hour, then bake!

Does it matter what bread you use for French toast?

Yes and no. After enjoying lots of French toast throughout my life, I’ve found that you can really make French toast out of any type of bread. However, the best French toast comes from bread that has some kind of texture, like sourdough, crusty French bread, brioche or challah, or even baguettes.

Other breads can be overly dense or too soft. If you have bread on hand and you’re not sure how it will work, it’s probably worth a shot!
