In the pantheon of breakfast casseroles, few rise above the elegance and simplicity of brioche French toast casserole. Sure, a sausage-egg casserole is a definite crowd-pleaser, and a stuffed ham-and-cheese croissant casserole is visually very impressive, but when you want to roll out the red carpet, impress your guests, and not break a sweat doing it, turn to this classic brioche French toast casserole.
Many recipes for French toast casserole call for soaking the bread overnight in the egg custard—and you can certainly do that—but we sped up the process in this recipe because not everyone needs the overnight window. In this case, just an hour will do.

Ingredients for Brioche French Toast Casserole
Whether or not this is your first brioche French toast casserole, none of the ingredients should be too surprising. In fact, most are likely in your cabinet right now. (The full ingredient list is further below.)
- Brioche bread: This eggy bread is extra fluffy and rich. It's better to use bread that is a little dry or stale.
- Eggs: For the custard.
- Half-and-half: You can use whole milk or cream if you have either of those, or a combination of the two.
- Dark brown sugar: We like the more molasses-forward flavor of dark brown sugar, but light brown sugar will work, too.
- Vanilla extract: To help balance all the flavors.
- Cinnamon: This warming spice is used twice in this dish for a cinnamon-forward casserole.
- Salt: Even sweet things need a pinch of salt.

For the cinnamon-butter topping, you'll need:
- Dark brown sugar: Again, we like the deeper flavor, but you can use light if that's what you have.
- All-purpose flour: To help make this topping nearer to a streusel.
- Cinnamon and nutmeg: Warming spices contrast beautifully with maple syrup or whipped cream.
- Butter: For the ultra-rich topping.
- Powdered sugar: To finish off the casserole.

What is brioche bread?
Brioche is a type of French bread that's made with an egg- and butter-rich enriched dough. It's softer, lighter, and far more fluffy than your average sandwich bread.
