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.
