How to Make Overnight French Toast Casserole:

This recipe is quick and easy! You will want to arrange the sliced bread atop one another (like shingles on a rooftop) and spread it in the baking dish. If you prefer chunks of bread, you can spread them evenly in the dish.

For a tasty brunch, prepare it the night before and leave it in the refrigerator overnight (or for at least 3 hours to soften). Don’t have that kind of time? You can still make it without soaking the bread; it is just as tasty!

How to Store/Reheat:

This overnight French toast casserole can be stored covered in the refrigerator for up to three days. To reheat, bake at 350 degrees for 10-20 minutes or until warm. For individual servings, microwave for at least one minute.

Wondering what else you can do with the rich and creamy eggnog leftover? Try it in oatmeal, coffee, or even as a frosting! For more ideas, here are 10 ways to use up leftover eggnog by The Kitchn.

I hope you can enjoy this simple and delicious overnight French toast with eggnog! Letting it soak the night before makes the mornings so much easier! Giving you more time to spend with your friends and family this holiday season!

Variations:

Not an eggnog fan? That’s fine! Try it with your favorite type of milk or dairy alternative.

If you avoid eggs, try flax eggs or another egg substitute. Make sure the bread product is also egg-free. Substitute regular milk or soy nog for the eggnog.

Gluten-sensitive? Use gluten-free bread!

Instructions

Set aside a greased 9 x 13″ pan.

In a medium bowl, whisk together eggs, eggnog, maple syrup, cinnamon, nutmeg, salt, and vanilla extract; set aside.

Halve the bread slices into triangles and place atop one another in the baking dish. If you prefer breaking the bread into pieces, spread evenly in the pan.

Pour eggnog mixture over bread pieces ensuring they are fully saturated by gently pressing down with a spatula or spoon.

Soak overnight (or at least a few hours) in the refrigerator.

Bake at 350 degrees Fahrenheit for 45 minutes (for a softer texture) to one hour or more for a firmer consistency.

Drizzle with maple syrup or top with fruit!
