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.

Love this recipe but despise that even your print page has ads.
Great recipe! How do I keep the casserole from deflating? I made a test run and plan to make it again for xmas.
I want to make this for Christmas morning ! Recipe calls for a loaf of bread but loaves are all sorts of sizes . How many ounces ? Thanks so much
I have the exact same question.
Same here! What size loaf??
Me too! I got the Pepperidge Farm farmhouse sourdough but it would help to know the oz weight.
A loaf of french bread, or brioche are pretty much the same size everywhere. This is a super easy dish to make on xmas eve. Just get a loaf and throw it together.
This has become a tradition I make it every Christmas morning. I just fill a 9×13 glass dish. I used a full loaf a few years ago & it was way too much bread. I just make sure it is not over the top of the pan.
Best Overnight French Toast, I add nuts (walnuts or pecans) & raisins. Yummy….A Christmas Morning tradition.
Everyone at the party went nuts and wanted the recipe.
This is my go-to recipe for Christmas morning and Easter. I use Challah bread and I dry out the bread cubes a bit in the oven on low heat so it’s not too soggy.
Truly delicious! Don’t skip the topping… made a nice sugary amazing crunch on top. I will probably not ever buy bread just to make this casserole, I use bits and pieces of raisin cinnamon bread, cinnamon rolls etc that get stashed away in the freezer. That being said, I wish the recipe had a measurement for bread other than oz. I used about 9 cups of bread cubes but ended up adding about 4-5 slices raisin bread more when it didn’t fill the dish significantly. I also didn’t measure out sugar into the eggs….I did sprinkle in a modest amount of cinnamon sugar mix and some other spices like cloves. The consistency turned out perfect and we will certainly be making this again! Thank you
My son loved it so much he has asked I make it again for Christmas morning 😍🎄I have made other varieties over the years and this one is his favorite.
I’ve eaten this bake on two different occasions when someone brought it to a get together and both times I felt absolutely horrible afterwards. Now I know why! It has 38g of sugar in a single serving.
This recipe was great, my 4 kids loved it but all had the same comment … too sweet and too soggy. I will try it again with 5 eggs and half the sugar. Otherwise, great beginning!
Okay, so I used 5 eggs 1/4 cup sugar 1 cup milk, 1 cup heavy whipping cream. More heavy whipping cream makes the egg mixture more like a custard, next time I might get rid of the milk altogether. I also used brioche loaf from trader joe’s as I’m not a fan of sourdough. Great recipe!
