First of all, what is French Toast Casserole?

French Toast Casserole is just like it sounds: french toast turned into a casserole. Basically, bread pieces that are soaked in a sweetened egg and milk custard, topped with a brown sugar streusel and baked. This can easily be turned into an overnight french toast casserole by soaking in the fridge overnight OR by baking immediately.

It is a special, sweeter breakfast that is perfect for any Holiday, especially Christmas Breakfast.

French Toast Casserole Recipe

Believe it or not, this french toast casserole is SO much simpler than making actual french toast. Less prep work and tastes just as delicious if not more so, thanks to that sweet streusel.

  • This recipe starts by cubing up some crusty french bread; about 10 cups.
  • Add the french bread to a buttered casserole dish and cover with a custard which is simply eggs, milk, sugar, vanilla, cinnamon, nutmeg, salt and heavy cream whisked together.
  • Soak the bread anywhere from 20 minutes while the oven preheats to overnight in the fridge.
  • Top with a simple streusel (flour, brown sugar, granulated sugar, melted butter, salt) and bake 45-60 minutes.
  • Cool slightly before cutting into squares and serving with powdered sugar, maple syrup, whipped cream, fresh fruit, etc..

Making Overnight French Toast Casserole

If you are planning on making this ahead, be sure to soak your bread in the custard overnight in a buttered casserole dish that is covered with plastic wrap or foil. I like making mine right before bed between 9 and 11pm. Then, the next morning you just have to remove from the fridge, add the streusel and bake. It’s such an easy, no fuss, forgiving recipe. Your family and friends will wake up to the delicious sweet smell of french toast without all the work for you. Prepare to blow them away at how delicious this french toast casserole bake is. A fabulous breakfast without having to break a sweat by 8am.

Adapting this recipe

The sky is nearly the limit to making this recipe your own. Based on your likes and dislikes, you can turn this into a new family favorite masterpiece! Here are a few ideas:

  • Add a tablespoon or two of booze into the custard (amaretto or rum!)
  • zest a lemon or an orange into the custard for a burst of flavor
  • Instead of french bread, try using brioche, cinnamon swirl bread or plain glazed donuts (YUM!!)
  • Dice apple or pear and add that in with the bread for a fun surprise
  • Layer fresh raspberries in with the bread for a more festive french toast casserole
  • For extra texture, add oats, chopped nuts or dried fruit to the streusel topping

French Toast Casserole

Delicious and decadent, this French Toast Casserole recipe is the perfect make ahead breakfast for any special occasion. Top it off with a sweet streusel topping for fresh and easy take on the classic french toast.
servings 12 servings
Prep Time 20 mins
Cook Time 1 hr
Total Time 1 hr 20 mins


  • 1 loaf crusty french bread cubed, about 10 cups*

For the custard

  • 1 3/4 cups cold milk
  • 1 cup heavy cream
  • 8 large eggs
  • 1/2 cup granulated sugar
  • 1 teaspoon vanilla
  • 1 teaspoon cinnamon
  • 1/2 teaspoon nutmeg
  • 1/2 teaspoon salt

For the streusel topping


  • Butter a 9x13 or other casserole dish. Place bread cubes into buttered dish.
  • In a large bowl, whisk all ingredients for the custard together until well mixed and uniform in color. Pour over bread cubes. Using a large spoon or your hands, press the bread cubes down into the custard to help everything soak in. (Cover and refrigerate at this point if storing overnight.)
  • Create streusel by mixing flour, sugars, butter, salt and pecans together to create moist crumbs. Sprinkle over the top of the bread.
  • Bake uncovered at 350 degrees for 45-60 minutes or until thoroughly cooked and the top of the casserole has browned. (If you notice the casserole is getting too brown, cover with foil).
  • Cool 10-15 minutes before cutting and serving. Top with powdered sugar and serve with warm maple syrup, fresh fruit, whipped cream, or anything else you'd like.


*I used a large, day-old loaf of french bread from costco that yielded about 10 cups of bread cubes. You want to fill your 9x13 or other casserole dish almost to the top with bread cubes.
