Have a hankering for fluffy, delicious French toast made easy? My sweet brioche French toast casserole with cinnamon crunch topping is golden and caramelized on the outside yet pillowy and creamy on the inside—it's everything we crave in traditional French toast, baked up in a sweet casserole!
Breakfast For Dinner with Brioche French Toast Casserole
It was a few weekends back when my intense craving for French toast struck...
I wanted French toast for dinner—something that the hubs and I sometimes like to enjoy when we're in the mood for comfort food that leans in the direction of sweet and “breakfasty”, and by that point, I'd been craving that golden, pillowy indulgence for days...
But here was the problem: I didn't want to go out, and, I was feeling a bit lazy.
The last thing I wanted to do was to stand at the stove dippin' and flippin' pieces of bread, frying them up in a pan one at a time.
That process was simply too involved for my liking on that particular late afternoon, so I had to come up with a more simplified alternative to get my French toast fix.
Enter this brioche French toast casserole where everything gets combined and spooned into a big baking dish, with no dippin' and flippin' required!

My Recipe for Brioche French Toast Casserole with Cinnamon Crunch Topping
It couldn't be easier to make a hot, fresh, delicious French toast casserole when you're hungry for this favorite breakfast staple, but aren't craving the somewhat involved process of preparing it.
Soft, rich, brioche bread is ideal for French toast casserole (or even the traditional preparation of French toast), and I love being able to simply cube up it up, whisk together the custard to create that creamy texture, and pour that over the brioche bread.
Before baking, I sprinkle on a sweet, cinnamon crumble topping to provide a bit of texture and aroma and really makes things extra indulgent.
This brioche French toast casserole is the perfect recipe when you're looking for a quick, throw-it-in-the-oven breakfast for the next morning, or would like to enjoy some breakfast for dinner like me!
Here's a sneak peek at my recipe for Brioche French Toast Casserole: (or just jump to the full recipe...)
- To get started, I prepare my casserole by cubing up some rich brioche bread into large chunks and placing them into large bowl. I whisk together my simple egg custard, and pour that custard mixture over the cubed bread, very lightly tossing to combine.
- I turn the mixture out into a prepared baking dish, cover with foil, and allow it to rest in the fridge for at least 3 hours so that the flavors marry and everything soaks in (or even overnight if I'm preparing this casserole for breakfast the next day.)
- Next, I prep my cinnamon crunch topping, and keep that separate (and cold) until I sprinkle it over the casserole just before baking.
- When ready to bake the brioche French toast casserole, I remove the foil, sprinkle on the topping, and bake for about 35-40 minutes until golden-brown.
- I serve while hot with syrup, or with our favorite warm blueberry compote.

Soft and puffy, this brioche French toast casserole with cinnamon crunch topping is an easy way to serve up a favorite breakfast staple!
Category: Breakfast
Cuisine: American
Yield: Serves 8
Nutrition Info: 360 calories per serving
Prep Time: 15 minutes (does not include resting time)
Cook time: 40 minutes
Total time: 55 minutes
Brioche French Toast Casserole Ingredients:
- 1 loaf brioche bread (16 – 17 ounce), cut into large cubes
- 6 eggs
- 1 ½ cups half and half
- ¼ cup granulated sugar
- 1 tablespoon pure vanilla extract
- Pinch salt (about a scant ¼ teaspoon)
- 1 teaspoon ground cinnamon
Cinnamon Crunch Topping Ingredients:
- ⅓ cup brown sugar
- ½ teaspoon ground cinnamon
- Pinch salt
- 2 tablespoons unsalted, melted butter
- ⅓ cup all-purpose flour
- Begin by gathering and prepping all of your French toast casserole ingredients according to the ingredient list above to have ready and organized for use.
- Lightly mist a medium-size baking dish with cooking spray, and set aside.
- To prepare the casserole, add the cubed brioche into a large bowl. In another bowl, whisk together the eggs, half and half, sugar, vanilla, pinch of salt, and cinnamon, and pour this custard over the cubed brioche. Toss very gently and carefully as to not break up the cubes, just until combined, and turn out into your prepared baking dish.
- Cover the casserole with foil and place into the fridge to rest for about 3 hours, or overnight if making ahead for the next day's breakfast. (You can skip this “resting” step, but the casserole may not be quite as light and fluffy inside.)
- While your French toast casserole rests, gather and prep all of your cinnamon crunch topping ingredients according to the ingredient list above to have ready and organized for use.
- To prepare the cinnamon crunch topping, combine the brown sugar, the cinnamon, the pinch of salt and the melted butter in a small dish, and mix with a fork. Add in the flour, and blend that in with the fork until crumbly. Set aside in the fridge until you're ready to bake the french toast casserole.
- When you're ready to bake, preheat the oven to 375°.
- Sprinkle the cinnamon crunch topping over top of the casserole and bake, uncovered, for 35 minutes turning half-way through the cook time for even baking. After 35 minutes, turn off the oven, and allow the casserole to stay inside for another 5-7 minutes.
- Then, remove from oven, dust with powdered sugar, if desired, and serve with warm syrup or blueberry compote.
Tips & Tidbits for my Brioche French Toast Casserole recipe:
- Brioche bread is best: A rich bread such as brioche is best for French toast, and is a dream for this casserole. It has extra body and flavor to it, and becomes nice and puffy, and creamy, when the custard is added and it's baked. (Challah bread is darn tasty, as well.)
- Give things a rest: In order to have the puffiest, most creamy-centered casserole, allow your assembled casserole to rest in the fridge for about 3 hours before baking it (you can even go longer to make it an overnight French toast casserole). Of course, you can bake it immediately, but allowing it rest and absorb the flavors and the custard helps create that perfect consistency.
- Optional add-ins: I love my French toast casserole nice and plain, because it best reminds me of traditional French toast, but feel free to add in raisins, chocolate chips, dried cranberries, fresh blueberries, or even pecans.
- Tasty toppings for brioche French toast casserole: We love traditional pancake syrup or maple syrup. And when we're craving a fruity slant, we enjoy spooning over my warm blueberry compote—so good!
- How to re-heat French toast casserole: Leftovers totally come back to life when reheated for about 5-10 minutes at around 325°-350° in a toaster oven—tastes just like it does when fresh!

And now I'm craving french toast. Gah, this looks so good!
The Cozy Apron
Hi Melissa, thanks! I’m already hungry for it again, and I just recently had it, lol!
The Novice
I love this! We try to have eggy-bread every Sunday in our home, so I hope to try this out soon 🙂
The Cozy Apron
I love this Sunday "ritual" of yours—how fun! Yes, if you're already a fan of "eggy bread" recipes, I really think you'll enjoy this simple and sweet casserole...happy cooking to you!
Skye Hambelton
Can you use regular bread or perhaps some hamburger buns I need to use?
The Cozy Apron
Hi Skye, if you're looking for a use for those hamburger buns and don't know what else to make with 'em, why not?
It may be a little different, but I'm sure it'll be a unique (and tasty!) use of them! 😉
Sandy
This is the perfect holiday breakfast item.
And PS - just made a 1/2 batch with some leftover bread for dinner tonight.
Yep! Just as good. 🙂
The Cozy Apron
Sandy, that made me so happy!
Yes, I agree that it truly is a perfect holiday breakfast, and I also love that you had it for dinner! 😉
Such a great way to use up some leftover bread— make a small batch!
Thanks so much for sharing.
Carolina Bass
could you make this, possible, plain and not in small pieces but whole slices and bake it? I saw one that had a blueberry compote on top, not sure if you would put the compote before baking it or after. Could you give me advice on this? thank you!
The Cozy Apron
Hi Carolina!
Unfortunately, I cannot advise you on preparing this using whole slices of bread, as I have not prepared mine this way. You can make it plain, meaning that you can leave off the cinnamon-crunch "topping" if you wish.
As far as the blueberry compote, you can certainly use my recipe for that! It's super easy and perfect for this. And you would not top it before baking the casserole, but afterwards, just before you serve it, if you wish.
I actually serve my compote warm on the side, so everyone can take as much as they like, and the casserole doesn't become soggy (especially if you have leftovers). Just a suggestion .
Hope you enjoy!
Carolyn Foley
What size is a medium baking dish? Thanks!
The Cozy Apron
Hi Carolyn, I measured mine so you could have a good estimate: it was roughly 12" (length) x 8" (wide) x 2.5" deep. So like a 13 x 9 (slightly on the deeper side rather than shallow) would be fine.
Hope you enjoy the recipe!
Kim
We have it in the oven now! I did it with Christmas leftover breads and did a double batch using 2 cups eggnog and one cup whole milk. A true Christmas leftovers casserole.
The Cozy Apron
Sounds delicious, Kim! Yes—true Christmas leftovers casserole...it's the beauty of a casserole, right?
Hope you enjoy!
Erin
Is the bread supposed to be 'doughy' after baking for the recommended time? I've never made a french toast casserole and I don't know what the consistency is supposed to be. The flavor is phenomenal.
The Cozy Apron
Hi Erin, not quite sure what you mean by "doughy". Because of the egg/half and half mixture (the custard), it should be slightly "custardy" in the center, and quite moist and tender/fluffy. 😉
Matthew Taylor
I have 2 different types of brioche bread I'm wanting to make this recipe but 1 of them looks alot thicker than the other, meaning denser.. any suggestions on which 1 I should use would be greatly appreciated
The Cozy Apron
Hi Matt, I'm kind of curious about your slightly denser one. I think it could hold up really nicely with the custard that gets incorporated into it, and should work just fine. Honestly, either would surely work, and my advice would be to go with your gut and choose the one you're leaning towards. 😉
Hope you enjoy this sweet treat!
Matthew Taylor
Thank you so much.. my 8 kids are looking forward to it, lol.. how long is the longest it needs to marry plz ma'am
