ingredient notes
Find the total ingredient measurements and instructions in the recipe card below!
- Brioche bread: You can use a whole loaf and slice it yourself or buy a presliced brioche loaf (make sure to cut thick slices!). You can substitute challah bread for the brioche if needed.
- Vanilla bean paste: This is similar to vanilla extract but is thicker and has actual vanilla bean specks in it. This french toast recipe is much more flavorful with it, but you can use regular vanilla extract in equal parts.
- Cinnamon: Feel free to substitute the cinnamon for pumpkin pie spice, apple pie spice, or any other seasonal spice combo.
- Milk: 2% or whole milk is best, this recipe has not been tested with alternative milk!
step-by-step instructions
Here’s how to make this easy brioche french toast bake! You will need a 9×13 or 8×11 casserole dish for baking the french toast. You will also need a large bowl to make the custard. Before you start, preheat the oven to 350 F/180 C.
STEP ONE: Toast the brioche bread. You can toast the bread in the oven or toaster oven, but the oven is easiest!
Lay the bread slices out in a single layer on an unlined baking sheet and toast in the oven for 10 minutes. Flip the slices halfway through baking. They should feel toasted but have little to no color when they’re done.
STEP TWO: Make the cinnamon sugar. In a small bowl, whisk together the light brown sugar, cinnamon, nutmeg, salt, and cardamom. Set aside.
STEP THREE: Make the vanilla bean custard. In a large mixing bowl, whisk together the eggs, milk, heavy cream, and vanilla bean paste.
STEP FOUR: Butter the baking dish. Pour the melted butter into the baking dish and set it aside.
STEP FIVE: Layer the toast in the dish. Once the toast is cool, layer them domino style into your prepared baking dish. Then sprinkle half of the cinnamon sugar mixture over the bread.
If using a smaller 8×11 dish, you may have to squish the slices a bit so they all fit.
STEP SIX: Pour over the custard. Pour the custard evenly over the bread, then sprinkle the rest of the cinnamon sugar mixture over the top.
Chill the french toast in the fridge for at least one hour, or overnight. When it’s ready to bake, cover the dish with aluminum foil and bake for 30 minutes.
Then uncover the dish and bake for 6-10 minutes longer, or until the tops of the toast look golden brown and the custard is puffed but still jiggly. Keep an eye on it when you take the foil off because the toast will burn easily!
expert baking tips
- Toast the bread. I know it’s tempting to just skip this step but the dry bread soaks up more of the custard!
- Don’t let it burn! Once the foil comes off the baking pan, keep a close eye on it after 5 minutes. A few minutes too long can cause the toast to burn and get way too crispy.
- Baking times may vary: All ovens are different, and your casserole may bake quicker or take longer than the indicated baking time. I recommend checking on it occasionally!
- Add toppings. While this french toast is amazing as is, adding fresh fruit or berry compote takes it to a whole new level!
storage & reheating
- Fridge: Store any leftovers in an airtight container for 3-5 days. You can reheat it in the oven at 350 F until warmed through!
faqs
You can get a similar result using challah bread. If you can’t find challah, any other type of thick bread like french bread should do well.
A dusting of powdered sugar, maple syrup, fresh blueberries, strawberries, sauteed apples, berry compote, etc. The possibilities are endless!
I do not recommend using all milk and no cream. The cream is what makes the filling custardy and creamy!
Yes! Use six slices of brioche bread and bake it in an 8×8 baking dish. Keep an eye on it while it bakes, it should bake in 20-25 minutes.

Notes
- Toast the bread. I know it’s tempting to just skip this step but the bread soaks up more of the custard which allows the french toast to maintain layers. You can also use day-old stale bread.
- Don’t let it burn! Once the foil comes off the baking pan, keep a close eye on it after 5 minutes. A few minutes too long can cause the toast to burn and get way too crispy.
- Baking times may vary: All ovens are different, and your french toast may bake quicker or take longer than the indicated baking time. I recommend checking on it occasionally!
- Add toppings. While this french toast bake is amazing as is, adding fresh fruit or berry compote takes it to a whole new level!
- Fridge: Store any leftovers in an airtight container for 3-5 days. You can reheat it in the oven at 350 F until warmed through!

Made this over Thanksgiving weekend. The whole family enjoyed it. I was able to make this ahead of time and it came out great.
I jus finished putting I in the fridge. I’ll need to report later on the finished product. However, my feeling is I wish I’d used more strawberries, maybe double the recipe. Also, frozen strawberries can be tart so after tasting the strawberry sauce per recipe, I’ll increase the sweetness next time.
Hi. In your ingredient picture you have 1/2c granulated sugar shown but it’s not listed under ingredients. Is this something we add ? Thank you!
Hi Vanessa! Sorry for the confusion, the granulated sugar was originally part of the recipe but I decided to leave it out after testing it again!
No problem, I ended up adding 1/4c and it was delicious. Thank You for the recipe!
Yum!! Never made a french toast casserole before and it turned out amazing! We ate ours Thanksgiving morning and served it with the strawberry sauce and cinnamon apples and overall was a hit!
