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.

    My 3 to granddaughter and I made this for a surprise breakfast for our family. I couldn’t find sourdough bread so I used French bread. This is the best recipe I’ve used to make this. The whole family loves it. My granddaughter was all smiles watching it disappear. Only recipe I’ll use from now on. Thank you.

    1. Lil'Luna Team says:

      You’re welcome!! I’m so glad the recipe was a winner for your family. Thanks for sharing!

  2. Tammy says:

    I’m making this for Bible study this evening we’re doing breakfast foods. I made a homemade strawberry 🍓 syrup for it and homemade whipped cream as well. I can’t wait to try it. I put mine in the crockpot after letting it set all evening. It’s afternoonish and I put it in crockpot on low. I figured I could keep it warm that way. Hoping I did everything right and it turns out okay. Thanks for the recipe. I will follow up.

    1. Lil'Luna Team says:

      Yes, please! We’d love to hear how it turned out. The strawberry syrup and whipped cream sound amazing. Hope the recipe was a hit!

  3. Ashlynn Keller says:

    Do you have any recommendations for making this in a slow cooker/

    1. Lil'Luna Team says:

      Yes! Make according to the recipe directions. Refrigerate for 6-10 hours in the ceramic crock pot. Place the ceramic pot into the heating base, cover and cook on low for 4 hours or high for 2 hours.

    This is a great recipe! My family enjoyed it very much. I used a loaf of stale baguette and a loaf gluten-free bread that was also slightly stale. It turned out fantastic anyway! Thanks!

    1. Lil'Luna Team says:

      I’m so glad to hear your family loved it!! Thanks for sharing what you did.

  5. Maria says:

    Do you need to bake with foil over dish first??

    1. Lil'Luna Team says:

      Nope, you can bake uncovered!

    Great make ahead for a teen brunch! I used a loaf of homemade GF bread and GF flour and you couldn’t tell the difference. My overnight cooks fast and it took a full hour for this to bake. I keep it covered the first 20 min and was glad because the top did not get too dried out.

    1. LilLunaTeam says:

      I’m so glad you enjoyed the recipe AND that it works well with GF ingredients too! That is so good to know Thanks so much for sharing what you did!

    Made this French toast casserole for my daughters birthday breakfast! Everyone loved it! I did sprinkle some plump blueberries on top before the brown sugar and butter topping then baked. So very good with some warm maple syrup and a squirt of whipped cream!

    1. LilLunaTeam says:

      Those blueberries and extra toppings sound heavenly! I’m so glad everyone loved it!

    Good flavor. It got rave reviews! ! Next time I’d like to add some nutmeg.

    How could I avoid the egg custard consistency at the bottom. Store it in a bowl overnight, don’t pour it into the pan until the morning? Anyone elses’ bake look like that? Thanks again for sharing. 🙂

    1. Lil'Luna Team says:

      So glad you enjoyed the bake! Nutmeg would be a yummy addition. You can definitely store it in a bowl until the morning then pour into the pan just before baking.

  10. Krystle says:

    I use a mixture of brioche bread and blueberry English muffins. Then I toss some blueberries over it before the streusel topping. To DIE for! Always get rave reviews. Thank you!

    1. Lil'Luna Team says:

      YUM! Sounds delicious! So glad you enjoy the recipe.
