Overnight French Toast Casserole is the perfect brunch dish for a crowd. Prepare it the night before, then bake and serve in the morning.
Whether it’s a holiday brunch or a cozy weekend morning at home, this Overnight French Toast Casserole is perfect for the occasion. Along with some Praline Bacon and Italian Sausage Breakfast Patties, it’ll be the perfect dose of comfort food to start your day!
The casserole is soft and custardy on the bottom and crunchy on top, thanks to the cinnamon-sugar-loaded bread cubes poking out from the casserole. Best of all, it’s really easy to make.
It’s made to sit in the refrigerator overnight, so start it the night before. In the morning, you’ll just need to bake it, make the coffee, and brunch is served!
- A one-pound loaf of french bread is the base of this recipe. It should be soft in the middle and a little crusty on the outside.
- Milk, eggs, and vanilla create a rich vanilla custard that the bread will soak up.
- Cinnamon and sugar dot the top of the casserole, which adds crunch and a gorgeous golden hue.
How to make french toast casserole
Start the night before by slicing the loaf of french bread into 1 inch cubes. I find that a large serrated knife is easiest for this—it cuts through the crust easily and doesn’t squish the soft and fluffy interior.
Place the bread in a greased 13×9 inch casserole dish. I grease mine with an oil mister, though cooking spray from the grocery store works great, too.
Whisk the eggs, milk, salt, sugar, and vanilla extract in a large bowl, then pour the mixture over the bread.
Press on the bread gently with your hands so it soaks up the vanilla custard. Then, cover and refrigerate the casserole overnight (or for a minimum of two hours).
The next morning, dot the casserole with butter, and sprinkle cinnamon sugar on top.
Bake for 45–50 minutes, or until golden brown. Let sit for 5 minutes before serving.
Then, cut into slices and serve with maple syrup.
How long do I have to refrigerate the casserole before baking?
Give the casserole at least two hours in the refrigerator before baking. You can keep it in the refrigerator for up to 12 hours, if desired.
What’s the best type of bread for french toast casserole?
Per its name, french bread is ideal. 🙂 A soft Italian loaf or brioche would work well, too.
French toast casserole is delicious on its own, but if you want to change it up, here are a few ideas:
– add a half of a cup of chocolate chips
– add a cup of fresh blueberries or sliced strawberries (or a mix of the two)
– drizzle the finished casserole with caramel sauce instead of maple syrup
When adding either the chocolate chips or fruit, toss them with the bread and then add the vanilla custard.
Maple syrup is a must for this casserole! It’s just lightly sweet on its own, so the syrup is the perfect complement.
For a protein-packed side dish, scrambled eggs or a quiche (like this asparagus & gruyere quiche) would make a great accompaniment.
