How to make overnight french toast
This simple overnight french toast bake starts with a French bread base (I like to use a thick, day old bread, so that it doesn’t become soggy). Then you’ll beat together the milk, eggs, brown sugar and cinnamon and pour it over the top. This will sit overnight and soak up nicely into the bread.
Then you’ll add a brown sugar crumb topping and berries to the top of the bread right before baking. I also love adding frozen mixed berries to the top, because we always have them on hand in the freezer. The berries make this french toast casserole extra delicious. I love the sweet flavor they add!
I love to cook my french toast casserole the full hour so that the top of the bread becomes a little caramelized/toasted and the center is cooked through. If you’d like the center more of a bread pudding texture, I would take it out about 15 minutes sooner. Either way it’s delicious!

Overnight French Toast Recipe
- 1 loaf day old french bread (sour dough or challah work great too, about 10 cups)
- 2 cups whole milk
- 7 large eggs
- 3/4 cup brown sugar
- 3/4 teaspoon cinnamon
- Pinch of salt
- 1/2 cup salted butter (cubed)
- 1/2 cup flour
- 1/2 cup brown sugar
- 1 cup berries (I used frozen)
- Grease a 9×13″ casserole dish and set aside.
- Cut the french bread loaf into cubes and layer evenly in the pan. You should have about 2 layers. Beat the milk, eggs, brown sugar, cinnamon and salt in a medium size bowl. Then pour evenly over the bread, making sure it covers each piece. Cover with foil and refrigerate over night, or at least 3 hours.
- In a medium size bowl, mix together the butter, flour and brown sugar with a pastry cutter or two knives. Use your hands if needed to make crumbs. Cover and refrigerate.
- When ready to bake, preheat oven to 350°F. Add the crumb topping on top of the bread and then evenly disperse the berries on top. Bake uncovered for 50-60 minutes, or until the top is lightly browned and the center is cooked through.
- Enjoy by itself or topped with syrup.
Hope you enjoy this french toast casserole! It has definitely become one of my family’s favorites to make over the years.
