Hi Friends!

This post for an overnight French toast bake first came about almost 10 years ago when I was looking for ways to use up my Thanksgiving leftovers. I was in charge of bringing a Costco-sized bag of dinner rolls to Thanksgiving dinner and we had a bunch leftover.

So I diced them up and make a french toast bake. It was perfect because I threw it together the night before, let it sit in the fridge overnight and baked it in the morning.

If you’re looking for more ways to use up Thanksgiving leftovers, try these Cranberry Meatballs or this Leftover Turkey and White Bean Soup.

Ingredients for Easy Overnight French Toast Bake

In addition to being able to make this ahead of time, this recipe is also made with just a few simple ingredients which is a major bonus. You need:

• Bread – Like I mentioned, I use dinner rolls but if you don’t have them, you can use cubed Italian bread or really any kind of hearty bread or rolls you have on hand. They work best if they’re a little stale.
• Eggs and milk – These are French toast staple ingredients and you’re making a big pan so you need a lot!
• Vanilla and Cinnamon – To add flavor
• Berries– You can use fresh or frozen. I like blueberries best but mixed berries also work.
• Brown sugar – To make a sweet crust on the top after baking

How To Make Blueberry French Toast Bake Casserole

To make this recipe you need a 9×13 pan. Line it with parchment paper for easy removal or grease it well.

If your bread isn’t stale, you can cube it and put it in the oven at 170 degrees F for 15 min or so.

To make the casserole:

• Cube the bread and put it in a 9×13 pan.
• Add the blueberries.
• Whisk together eggs, milk, vanilla and cinnamon and pour over the bread.
• Use your hands to mix it all up and make sure all the bread is coated.
• Cover with saran wrap and press down to flatten and refrigerate overnight.
• When ready to bake, remove the saran wrap, sprinkle with brown sugar, bake and serve.

If you had extra cranberry sauce, you could mix some of that in as well!
