How to Make Overnight French Toast Bake
Start by cutting your loaf of sourdough bread into cubes. Sourdough is the best bread to use for a french toast bake. However, you can use Italian or French bread and it will still be sweet and yummy!
Grease a 9×12 baking dish and throw your bread cubes in, spread evenly throughout the dish. Then grab a mixing bowl and mix together the eggs, milk, heavy cream, sugar and vanilla.


Pour the mixture evenly over the bread. Then cover your dish with cling wrap and refrigerate it overnight (or until you can’t wait any longer!)
Next is the sweet and sugary topping! Mix together flour, brown sugar, cinnamon, and salt in a medium bowl. Cut in butter with this mixture until crumbly and place in a baggie or small, lidded container and refrigerate overnight as well. You can either make the topping the night before or just wait until the morning.


The next morning when you are ready for your sweet and scrumptious breakfast, preheat the oven to 350 degrees. Take both containers out of the refrigerator and sprinkle the topping evenly over the bread.
Bake for 45-55 minutes until the top is crispy and the bottom no longer wet. Serve with powdered sugar, syrup, or the topping of your choice!

Notes & Tips
Substitutions for Overnight French Toast Bake
- Bread: I have always preferred sourdough bread for french toast or french toast casseroles. You can use any kind of bread, even cut up bagels, depending on what you have.
- Syrup: Use a blueberry or strawberry syrup to add a fruity flavor to this dish. Or Scratch the syrup altogether and make a delicious icing using powdered sugar and milk.
- Heavy Cream: If you don’t have heavy cream on hand you can still enjoy this tasty breakfast without running to the store! Just replace the same amount of heavy cream with some extra milk.
- Mix-ins: Add fresh blueberries, strawberries or raspberries to add some extra flavor if you prefer.
- Overnight Refrigeration: If you forgot to prepare your french toast casserole the night before, don’t worry you can still make it for breakfast! Just follow the same steps but when you get to the overnight refrigeration, just let the egg mixture soak into the bread for about 10-20 minutes. Then you can continue to follow the rest of the directions.
How to Store Overnight French Toast Bake
Refrigerator: Store any leftovers in the refrigerator, either in an airtight container or by throwing some plastic wrap over your casserole dish. Rewarm by putting the desired amount in a glass dish and baking at 350° for 10-15 minutes.
Freezer: You can freeze any leftovers for up to three months. When you’re ready to eat, put it in the refrigerator or on the counter to thaw. Then bake at 350° for 10-15 minutes.
