Brioche French Toast Casserole Recipe Ingredients
- Brioche Bread. Buttery brioche bread is a slightly sweet bread with a light, fluffy, and soft texture that is perfect for French toast casserole! Grab a loaf of brioche bread at your local grocery store or a local bakery! If you love to bake bread, homemade brioche bread is a great option too.
- Large Eggs. Eggs are a must for making the perfect custard mixture for French toast or French toast casserole! Plus, eggs are a nutritional powerhouse and add protein to this easy brioche French toast casserole recipe!
- Milk AND Heavy Cream. Heavy cream must for the perfect, rich French toast custard mixture. However, with this baked French toast casserole, lightening up the mixture with some 2% milk (or whole milk) creates a better balance for this dish. It also lowers the fat content of your breakfast casserole, which is a little added bonus in my book.
- Brown Sugar. Used to sweeten the custard for your overnight French toast casserole. You can use light brown sugar or dark brown sugar, both will work great! Light brown sugar has a more subtle flavor than dark. Use whichever you prefer!
- Cinnamon. Adding ground cinnamon to your custard mixture adds a wonderful pop of flavor and really enriches the whole French toast casserole’s flavor profile.

Helpful Equipment
You will need a 9×13 pan to make this easy brioche French toast casserole recipe. You can use a simple Pyrex glass 9×13, or a pretty ceramic 9×13 which can double as a nice serving dish!
How To Make French Toast Casserole (Brioche Bread)
Add eggs to a large mixing bowl and whisk.
Add milk and heavy cream to the eggs, and whisk again.
Add brown sugar, vanilla extract, salt, and ground cinnamon to the egg, milk, and cream mixture.
Whisk until well combined. Set custard mixture aside.
Cut brioche bread into 1″ cubes.
Place bread cubes into an even layer in a greased 9×13″ baking dish. Pour custard mixture over the top.
Gently press dry bread cubes down into the wet custard mixture to ensure all pieces have been moistened.
Cover with tinfoil set in the refrigerator to rest for a minimum of 2 hours (up to overnight if time allows).
When ready to bake, pull the brioche French toast bake out of the fridge while the oven preheats to 350°F. Bake, still covered with tinfoil, for 20 minutes. Remove tinfoil and continue to bake for another 20-25 minutes until the casserole has puffed up, the edges are golden, and the bake is set.
Variations For This French Toast Casserole With Brioche
- Use challah bread. Challah bread is a great substitution for brioche bread in this recipe if it is easier for you to find! Challah is a yeast bread that is made from an enriched dough (similar to brioche), but uses oil instead of butter when being made.
- Lighten up your custard mixture with half and half. If heavy whipping cream isn’t your thing, you can lighten up your custard mixture by using half and half instead of the heavy cream.
Possible Dietary Restrictions?
This baked French toast brioche casserole recipe is vegetarian as written.
Make this into a gluten free French toast casserole by selecting a gluten free brioche bread (or gluten free challah bread).
Overnight French Toast Casserole Brioche Tips
Allow your brioche French toast casserole to rest overnight. Turning this into an overnight French toast casserole is great for several reasons:
- Allowing the bread to sit overnight allows the custard to soak into the bread, ensuring no dry spots when baked.
- It’s super convenient! It only takes 10 minutes to prep this dish, cover and place it in the fridge overnight, and wha-la! You can have fresh baked French toast casserole ready to enjoy in the morning!
Have your pan covered for the first half of baking. This helps to avoid an overly dark or crispy top on your French toast bake.
Toppings For Brioche Bread French Toast Casserole
The classic way to serve this brioche French toast bake would be a dusting of powdered sugar plus a (generous) drizzle of pure maple syrup. Fresh berries in addition to these are also very popular!
Other French toast topping ideas include:
- Fresh berries – strawberries, blueberries, raspberries.
- Pure maple syrup.
- Powdered sugar.
- Whipped cream.
- Fruit syrups – blueberry syrup, strawberry syrup, etc.
- Fruit compotes – cherry compote, mixed berry compote, etc. This homemade rhubarb compote with strawberries and apples would be a great choice too!

What Pairs Well with French toast?
French toast pairs well with egg dishes like scrambled eggs, fried eggs, or a simple omelet. Adding a salty meat like bacon or breakfast sausage patties or links is a nice complement to the sweetness of French toast. A fresh fruit salad is also a great addition to a breakfast spread with French toast.
Storing French Toast Casserole With Brioche
Store leftover French toast casserole in an airtight container in the refrigerator for up to 5 days.
If you plan to reheat a large portion of the French toast casserole in the casserole dish, do so by placing the dish into the oven at 350°F until warmed through. Alternatively, small portions can be reheated in the microwave.
Brioche French Toast Casserole FAQs
Brioche bread is made with an enriched dough with a high proportion of eggs and butter. Brioche is known to be slightly sweet, has a light, fluffy, and soft texture, and has a rich taste. It can be used for both savory and sweet dishes.
Generally you want any type of bread you are using for French toast to be slightly stale. This is because really fresh bread tends to soak up the custard batter that it is dipped in, which can lead to soggy French toast.
If you have a fresh loaf of bread, you can help dry it out a bit in a few ways:
I like to simply open the package and set the bread out on a wire rack and let the air do it’s job for 30-60 minutes. You can work on prepping the rest of your recipe while you do this.
You can expedite the process by placing slices of the bread on a baking sheet and place it in a 300°F oven for 5-7 minutes.
Season your French toast batter! While eggs and milk are the only essentials needed to make a classic custard base/batter for your French toast, adding cinnamon, vanilla, and even sugar helps to liven everything up! You can also try blends, like pumpkin pie spice, to add even more depth of flavor to your French toast.
There is likely too much custard mixture. If your French toast casserole is too wet, this can lead to a soggy casserole. We’ve never had an issue with this recipe turning out soggy because we’ve perfect the ratio of custard mixture to bread. And the use of rich brioche bread is also helpful in soaking up all the custard mixture goodness to create the perfect French toast casserole!

I made this recipe for the first Friday of Lent and the pan disappeared SO fast. The brown sugar and heavy cream definitely elevated it above other similar recipes I have tried. Pair it with some eggs and fruit and you have a well balanced (and filling) meal.

If Jesus were to make French toast – this would be it. I could eat this every day and not get tired of it! It could be great for breakfast but also a late night snicky snack when you’re needing a sweetsy treat. 11/10 rating hands down! You would be doing yourself a disservice if you chose not to make this recipe.

BEST REVIEW EVER. So happy you loved it Laura!

This was delicious! Mine turned out a bit wet in the middle even after baking as described above and using the same brioche loaf size. Next time I’ll make slightly less custard. Regardless, it was still a big hit at our house!
