What You Will Love
This is the perfect breakfast recipe for special occasions like Christmas or Easter morning. Just prepare this overnight french toast casserole recipe the night before, and pop it in the oven the next morning. It's also a great brunch recipe for weekend mornings or mother's day.
The egg, milk, and brown sugar form a custard mixture that soaks into the buttery brioche bread. The brown sugar, butter, and pumpkin spice topping add a caramel pumpkin spice flavor.
- Brioche loaf: I highly recommend bakery brioche or challah bread for this recipe. You can also use french bread.
- Milk: Use whole milk, 2% milk, or fat-free milk. I recommend using cow's milk because I haven't tried making it with alternative milk. If you do, drop a comment and let us know how it turned out.
- Eggs: Whole free-range eggs.
- Brown sugar: Use brown sugar, light brown sugar, or white sugar. The problem with brown sugar is that it clumps and hardens together if sitting in an open bag in the pantry. Save yourself the hassle, and substitute white sugar if your brown sugar is clumped.
- Butter: My favorite butter is Kerrygold salted butter.
- Pumpkin spice: This is a ground spice found in most U.S. grocery stores in the spice section. Substitute equal parts ground cinnamon if you don't have it.
See the recipe card at the bottom of the post for quantities.
Make the custard mixture by mixing the eggs, milk, sugar, vanilla, and a pinch of salt. Slice the bread into chunks and add them to a casserole dish. Pour the custard mixture into the bread. Top with sliced butter, sugar, and pumpkin spice. Bake at 375℉ (190 ℃) for about 30 minutes.
How To Make Brioche French Toast Casserole
Crack the eggs into a large mixing bowl. Whisk the eggs.
Add the milk to the whisked eggs.
Add half of the brown sugar, half of the pumpkin spice, all of the vanilla extract, and a pinch of salt.
Whisk everything together really well.
Cut the brioche bread into large chunks (about 1.5" in size). Add the bread cubes to a greased 9" x 13" baking dish.
Pour egg mixture onto the cubed bread. Allow the bread to soak for a minimum of 20 minutes.
Slice the butter. Lay it on top of the bread in a single layer. Sprinkle the remaining brown sugar and pumpkin spice on top of the casserole.
Bake in a 375℉ (190 ℃) oven until golden brown (about 30 minutes). Dust with powdered sugar.
Serve with maple syrup, fresh fruit, homemade sausage, or bacon.
Tips and Tricks
Let the custard mixture soak into the bread for a minimum of 20 minutes. This easy french toast bake can be made ahead the night before too.
Use good-quality bakery bread. I don't recommend using sliced bread in the grocery store bread aisle.
Weigh the sugar. Brown sugar is deceptive when measured by volume. When it's not packed, it takes up twice the volume.
The brioche french toast casserole might puff up in the oven; this is normal!
Variations and Substitutions
- Substitute challah bread or french bread for brioche bread.
- Use ground cinnamon instead of pumpkin spice.
- Substitute white sugar or light brown sugar for brown sugar.
This french toast recipe can be made ahead. Store in an airtight container (or add plastic wrap on top) in the fridge overnight. Bake the next morning.
The breakfast casserole should not be soggy. It should have a custard-like texture and a golden brown top.
Serve french toast casserole with sausage, bacon, fresh fruit, and some maple syrup.
