Overnight French Toast Casserole
Overnight French Toast Casserole is the kind of breakfast recipe that makes mornings easier and feel a little more special.
Cubes of bread soak overnight in a rich cinnamon-vanilla custard, giving you a soft center with perfectly golden edges after baking.
It’s ideal for holidays, brunch gatherings, or weekends when you want a warm breakfast without standing over the stove flipping slices one at a time.
Prep everything the night before, refrigerate, and wake up with breakfast practically ready to go.
Make-ahead casseroles are a favorite for busy mornings because all the work happens in advance.

How to Make French Toast Casserole
- Grease a 9×13 baking dish and fill it with torn bread pieces. Bread choices like stale or day old brioche and challah often create a richer texture because they absorb custard well while holding their shape.
- Whisk together the eggs, milk, cream, sugars, and vanilla, then pour the mixture over the bread.
- Cover and refrigerate overnight for the best flavor and texture.


- Prepare the cinnamon crumb topping separately and refrigerate until ready to bake.
- Before baking, sprinkle the topping over the casserole and bake until golden and set.
- Let rest for 5 minutes, then serve with powdered sugar and maple syrup if desired.
