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.

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.

Made this using one can of unsweetened coconut milk and added a little bit of water instead of the milk and heavy cream for some with milk allergies. Everything else was just as the recipe called for, including the topping. Baked it about 55 mins. Turned out wonderful and received many compliments.
Your receipes are so delicious. Can’t wait to try some of them.
I’ve made this recipe many times and it is a staple for every holiday brunch I host. Every single time, my guests RAVE about this recipe! It’s always the show-stopper and I have yet to have any leftovers remaining. It is absolutely delicious!!!
Delicious!!!!! Everyone loved it and asked for the recipe:)
Absolutely love this dish! So easy to make the night before and everyone I’ve served it to wants the recipe.
I am wondering if it’s possible to do with almond milk? I have a brunch coming up and the host is dairy free.
I doubled this recipe and served it at a bridal shower this past weekend. It was a big hit! I can see this becoming a regular feature on our family gatherings. The overnight casserole is such a time saver in the morning as well.
Hi! What kind of bread did you use? Any changes to the recipe? This is a great idea for a bridal shower!
My husband and I loved, loved, loved this recipe. I don’t like dry French Toast, so baking it for 45 minutes produced a soft, eggy result that reminded me of bread pudding. The vanilla in the custard, and the cinnamon crumble on top gave it the perfect layers of flavor and contrasting textures. Fantastic!
I used a large loaf of Italian bread from a local bakery, and because the dry cubes filled the 15″x 10″ Pyrex glass baking pan
I increased the amount of ingredients to make 10 servings instead of the 8 in the original recipe. Perfection!
It was delicious. Tasted just like a really good french toast. No syrup needed as it’s very sweet already!
I let the mixture sit in the refrigerator for two days without cooking it. Is it still ok to add the topping and bake??
You should give it a try and see! I haven’t ever left it that long, so I’m not totally sure. You’ll have to let us know.
I have made this several time for family brunch and everyone always raves about it.
What is the size (oz) of the sourdough bread loaf that you use?
I usually use a 24 oz loaf, but it can be a little more/less, give or take.
