French Toast Casserole is one of our family’s favorite breakfast recipes. In fact, we make it for special occasions all year long and ALWAYS on Christmas Day. Thick cubes of bread are soaked in a sweet vanilla custard and topped with a buttery cinnamon crumble. It is simple enough for a weekend breakfast and special enough for holiday breakfast or brunch.
The best part is that you can prepare everything the night before. In the morning, just pop it in the oven and let it bake. It’s not only delicious, but feeds a crowd and is especially perfect for feeding guests in town.
For other breakfast favorites, check out our Sausage breakfast casserole and classic holiday breakfast casserole. And if oyu are looking for something equally as impressive to pair it with, try our Easy Candied Bacon.
Why we think you’ll love it:
- Simple. The easiest make-ahead breakfast for holidays or weekends.
- Customize. Easy to customize with fruit, nuts, or chocolate chips.
- Holiday perfection. Perfect for Thanksgiving, Christmas, or any special occasion AND perfect for feeding a crowd or enjoying leftovers later.
- Your house will thank you. Our French Toast Bake smells amazing and looks beautiful with minimal effort.
French Toast Casserole Ingredients
- Bread (1 24-ounce loaf of sourdough, brioche, French bread or challah): The main idea is that you want the bread to be sturdy enough that the bread cubes will hold up after being combined with the egg mixture.
- PRO TIP: For any of these breads, you can slice and toast or let slices sit out for 24 hours to make them more stale and sturdy.
- Eggs (8 large): Create the rich custard and give the casserole structure.
- Milk (2 cups) and heavy cream (½ cup): Add moisture and richness.
- Vanilla extract (1 tablespoon): Adds warm, sweet flavor.
- Sugar (¾ cup): Sweetens the custard perfectly.
Topping
- All-purpose flour (½ cup): Helps create the crumble texture.
- Packed light brown sugar (½ cup): Adds caramel-like sweetness.
- Ground cinnamon (1 teaspoon): Brings warm, cozy flavor.
- Salt (¼ teaspoon): Balances the sweetness.
- Cold unsalted butter (½ cup, cut into pieces): Creates the crumbly, golden topping.
How to Make French Toast Bake
BREAD. Cut bread into 1-inch cubes and scatter evenly in a greased 9-x-13-inch baking dish.
EGG MIXTURE. In a medium bowl, whisk eggs, milk, heavy cream, vanilla, and sugar together, then pour evenly over the bread.
CHILL. Cover the dish with plastic wrap and refrigerate for at least 4 hours, or overnight.
TOPPING. Mix flour, brown sugar, cinnamon, and salt in a medium bowl. Cut butter into this mixture until crumbly. Place the topping in a small resealable plastic bag and refrigerate overnight as well.
BAKE. When ready to bake, preheat the oven to 350°F. Unwrap the baking dish and sprinkle the topping evenly over the bread. Bake, uncovered, for 45–60 minutes, depending on how soft you like it. This overnight French toast casserole should be soft on the bottom and crisp on the top.
Serve it with some of our favorites, including: Buttermilk Syrup, Cinnamon Buttermilk Syrup, Whipped Cream and sliced strawberries
Kristyn’s Recipe Tips
- BREAD. Choose sturdy bread such as sourdough, challah, or brioche so it can soak up the custard without getting soggy.
- OVERNIGHT. Soak overnight to let the flavors deepen and the bread fully absorb the custard.
- TOPPING. Keep the topping chilled until you are ready to bake, then sprinkle it over the bread for the best texture.
- TOO SOGGY. If your casserole comes out too soggy try some of these tips:
- Soak the bread in a separate bowl. If there’s too much egg in the pan it may be left a little soggy. One way around this is to store your bread mixture overnight in a bowl. In the morning, transfer the bread to the baking dish leaving behind the extra liquid.
- Not soaking the bread long enough. You want the egg mixture to seep deep into the bread for a soft custardy center. If the mixture doesn’t have time to soak into the bread it may end up creating a soggy mess.

This is a true 5-star recipe!!!
So much so, that I’m taking the time to leave a big THANK YOU to Kristyn. No exaggeration: this was The Best overnight French toast I have ever made and one of the best dishes I have ever made. The flavours, the textures, everything came together beautifully.
Followed the recipe to an S: used a trio of different bakery items that were on the verge of dumpation. One even had plum jam. I dont know if that will need to be a secret ingredient in future reincarnations of the recipe.
In short: loved it!
(And it tastes great reheated too.)
Thank you SO much!! I’m so happy to hear that you loved the recipe!!
I have made so many different French toast casserole recipes through the years, and this is now my favorite. Thanks fir sharing. It is so good!!!
You’re welcome! I’m so glad you found the recipe and enjoy it!
Hi! What size loaf of sourdough do you use in oz?
Thanks!
Mikaela
I’d say a 16-24 oz. loaf would work great!
Is it possible to make this with less egg? I was thinking half (like 4). My youngest son has an egg allergy and can only take small amounts at a time if it’s mixed into a recipe. I’m scared to use 8 eggs!
I haven’t tried it with less eggs than the recipe calls for… so I’m not totally sure how well it will stay together and what the texture would be like. You can certainly give it at try and see though! You’ll have to let us know if it still turns out well with less eggs.
This recipe is great! I’ve made it several times using both challah and sourdough bread.
Mmm I bet they both turned out delicious!! Thanks for sharing. So glad you enjoyed the recipe!
Thank you for this recipe it’s a perfect snowy winter morning brunch my whole family loves it! I’ve made it several times using kings Hawaiian rolls and it comes out fantastic everytime. I used the suggestion of soaking the mixture in a separate bowl and straining spoon and transferring into my baking dish the next morning and I’ve have had great results time and time again. You will not be disappointed, it’s amazing definitely a must try!
Sounds tasty too! Thanks for sharing what you do.
Always a hit when I make it. Can you make it and freeze for another time or something to take to someone?
Yes! You can choose to freeze it before or after baking. Wrap dish with plastic wrap then foil. It can keep for up to 2 months in the freezer. When you’re ready to eat thaw overnight in the fridge, remove all the wrapping and bake. If it been prebaked cook at 350 degree F for 20 minutes. If it has not been pre-baked, cook according to recipe directions.
Made this recipe for a family gathering, it is amazing.
Thank you!! I’m so glad you enjoyed it!
Second time making this French toast, the favorite of my whole family with the exception of one son who likes one with cream cheese mixed in (the others hate that of course). The first time I used sourdough as recommended, and this time I used a loaf of ciabatta that I had sitting around for too long. Both very tasty but the textures very different. The ciabatta version ended up looking almost like a coffee cake, with the consistency of bread pudding. Now we have mixed reviews on which was better, but we all enjoyed both. Thanks for a great recipe!
You’re welcome!! Glad that you and your family enjoyed the bake!!
Made this casserole for a pot luck brunch. It was a huge hit. Everyone went back for seconds and wanted the recipe! I tweeked the recipe a bit though. I added almond extract and cinnamon to the egg mixture.
I’m so glad to hear it was a hit! Thanks for sharing what you did. 🙂
