Overnight French Toast is the perfect breakfast for a lazy weekend morning. All you have to do is mix up the eggy custard the night before, then soak your bread in it overnight.

In the morning, simply pop it in the oven and enjoy! This recipe is easy and delicious, and the buttery, cinnamon-toasted topping will definitely become a family favorite.

about Overnight French Toast Casserole

Our Overnight French Toast bake takes the traditional French toast and turns it into a casserole with far less effort than frying and flipping individual pieces!

Filled with the same flavors of the classic stovetop slices, this easy-to-make morning meal takes 10 minutes to prepare simply by covering a bread base with a custard mixture, allowing it to soak overnight and baking it the next day with a buttery cinnamon-sugar topping sprinkled on top.

This easy French toast recipe, just like my french toast muffins, is perfect for feeding a crowd, but instead of preparing bite-sized portions, a french toast overnight casserole can be assembled in a single pan.

Serve your overnight baked French toast casserole with a side of syrup, fresh fruit, or a dusting of powdered sugar; it’s a delicious dish made with minimal effort but never disappoints.

Why We Love French Toast Overnight Casserole

  • Quick and easy to prepare in 10 minutes.
  • Uses simple kitchen staple ingredients.
  • Tastes like traditional French toast but is made with minimal work.
  • As the casserole sits, the bread absorbs the custard so it’s super soft and moist in the middle.
  • Perfect make-ahead dish for a lazy morning meal, holiday brunch, or easy weekday breakfast.
Overnight French Toast ingredients


  • French bread or Italian bread
  • Eggs
  • Whole milk
  • Heavy whipping cream
  • Sugar
  • Light brown sugar
  • Vanilla extract
  • All-purpose flour
  • Cinnamon
  • Salt

Substitutions and Additions

  • Bread Base: Feel free to swap the French or Italian bread with challah, brioche, sourdough, or another uncut loaf as long as it is sturdy enough to hold up after being combined with the egg mixture.
  • Serving Suggestions: I love serving my baked French toast with maple syrup, banana slices, fresh berries, powdered sugar, greek yogurt, or even a dollop of homemade whipped cream.
  • Add Some Spices: Add some freshly grated nutmeg, pumpkin pie spice, or apple pie spice to the custard mixture. 
  • Make With Other Milks: Instead of using dairy milk, you can use your favorite milk alternative. Try experimenting with oat milk, coconut milk, almond milk, or soy milk.

Frequently Asked Questions

Can I freeze my overnight French toast bake?

Yes, you can freeze your casserole either before or after baking. Wrap the completely cooled baking dish with plastic wrap then foil. It can be frozen for up to 3 months. When you’re ready to eat, thaw overnight in the fridge, remove the wrapping, and bake. If your French toast casserole has already been baked, reheat at 350 degrees for about 20 minutes. If it has not been baked, bake it according to the recipe directions.

Why is my French toast casserole soggy?

This overnight French toast casserole should be soft on the bottom and crisp on the top. If your bread base seems too soggy, you may not have soaked the bread long enough. Make sure your egg mixture has completely seeped into the bread to create a soft custardy center before baking.

Can you make overnight french toast the same day?

I know it sounds counter-intuitive to make overnight French toast the same day, but you don’t have to let it sit in the fridge overnight. If you are pressed for time, you could prepare your dish in the morning and bake it in the afternoon for brunch or at night for brinner (breakfast for dinner). As long as the bread has enough time to soak in the egg mixture (at least 4 hours), it should be ok.
