Ingredients
Brioche Bread - brioche is a bread of French origin and has a soft and buttery texture. It is made with eggs and butter which makes it rich and soft in texture. It is perfect for French toast!
Eggs - I use large eggs which are one of the main ingredients in the liquid mixture that gets poured over the bread.
Heavy Cream and Milk - I used heavy cream AND milk in this recipe to add richness to the casserole.
Brown Sugar - brown sugar is in the casserole itself and in the topping, adding sweetness to the casserole.
Cinnamon - I love the flavor that the cinnamon adds!
Flour - in the crumb topping.
Butter - also in the crumb topping adding some crunch and yummy butter flavor.

Variations
Different Bread - instead of brioche bread, you could definitely use challah, French bread, thick sandwich bread, or an Italian loaf.
Substitute Heavy Cream - if you don't have heavy cream, you can just use milk, which will still be delicious but not quite as rich and decadent.
Spice it Up - if you want more spices than cinnamon, you can add nutmeg, cloves, and ginger.
Add Fresh Berries - Add 1-2 cups of fresh berries like raspberries, blueberries, or strawberries.
Lemon or Orange Flavor - add some lemon zest or orange zest to the custard mixture for a fun change of flavor!

Expert Tips
Serving Suggestions - we love this brioche French toast casserole recipe topped with maple syrup and alongside some fresh blueberries and raspberries. Sometimes we also do scrambled eggs and Jalapeno Bacon!
Reheat - to reheat this baked French toast casserole, you can place the entire baking dish in a 350 degree oven for 10-ish minutes to reheat, or microwave smaller servings on a plate for 45-60 seconds.
Storage - store leftovers in the baking dish covered with plastic wrap or foil, or transfer to an airtight container. This will last for 3-4 days in the fridge.
Recipe FAQs
Yes! You can freeze it prior to baking. Once ready to make it, thaw it overnight and then bake according to instructions. You might need to add an additional 5-10 minutes to account for starting from a colder temperature.
Definitely. While I love brioche for its sweeter flavor and delicious texture, you could use French bread, Italian bread, or thick sliced bread like Texas toast.
It could be that it is underbaked or that the bread you used is too soft. You don't want to use thin sandwich bread, as it won't hold up well to the custard mixture. This is what makes brioche perfect for French toast casserole, as it holds up well.
