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.

    Di you think i gould use sourdough english muffinS vrojen into pieces For this? My lical grocery stire doesnt carry souRdough bread.

    1. Kristyn Merkley says:

      I have never tried. It really isn’t a doughy bread, so I am not sure how it would turn out.

  2. Terel says:

    I noticed once your bread was all cubed up in the pan, it looks yellow. There are some plain pieces iN there that seemed Untouched But mOst all in the video the bread is yellow. Did you butter the bread as it sits overnight?

    1. Kristyn Merkley says:

      In step two, you will pour a few things over the bread & let sit overnight 🙂

    This was awesome! I modified based on what I had on hand and time: loaf of french bread that I left out for about a day; all 2% milk with No cream; and only had it refrigerate for about 3 hours. It took about a full hour to cook through. I have 6 kids – all loved it, no leftovers. I will make this again and again – thank you!

    1. Kristyn Merkley says:

      Yay!! Kids love this stuff! I am glad yours did! Thank you so much!

    This casserole is so delicious! I baked mine 1 hour, because we like it crunchy. I will definitely make it again soon and share the recipe with my friends. It’s perfect for busy morning. The only thing I will change cut back on the white sugar.

    I can’t say enough nice things about this recipe. I just bought my first home with my boyfriend and we had my family over for brunch and to see the place. normally my family is not a sweet breakfast type, however, I presented this as a “side dish” (we are Italian, most of our side dishes are normally the main dish size) and they loved it. My ma has raved about it for days now. The best part was getting to do this the night before and the day of I just had to pop in the oven. Bravo to this recipe!

    1. Kristyn Merkley says:

      Love this! I am so happy to hear that! Thank you so much for giving it a try & congrats on the new house!
