Overnight French Toast Breakfast Casserole

The other day, I cooked a double batch of artisan bread and it didn’t turn out that great. I didn’t want to throw it out, so instead, I turned part of it into yummy garlic bread, fed some to my kids {who don’t know better…}, and then used the rest to make this delicious French Toast Breakfast Casserole!

This make ahead French Toast Breakfast Casserole recipe is so great! Throw it together at night before you go to bed, pop it the oven when you roll out of bed, and a half hour later, breakfast is served! You’re welcome.

If you have bread to use up too, I highly recommend this recipe. It’s quick, easy, and really tasty. It’s not that nutritious, but everything in moderation right?! I adapted the recipe I found here.

Ingredients for Easy French Toast Casserole Recipe

  • butter
  • brown sugar {I use raw sugar}
  • old bread (use French bread, homemade bread, sourdough bread, or any variety you enjoy)
  • eggs
  • whole milk or heavy cream
  • vanilla extract
  • cinnamon
  • chopped pecans

Let’s make this Overnight French Toast Casserole

The great thing about this casserole is that you can either bake it immediately after assembly, or you can cover and refrigerate over the night. Both options have their merit. If you’re organized the evening before, assembling at night is a great way to simplify busy mornings.

But if you want to make it and cook it right away in the morning, that works too! Totally your call.

cut the bread into thick slices for overnight french toast casserole

To start, slice up a loaf of old bread into thick slices – around 1″ thick. Stale bread really works best in this recipe. It might sound strange, but I promise it’s the truth.

melt butter and add sugar

Melt butter and add sugar, then put the flour brown sugar mix on the bottom of a 9×13 inch pan. place the bread in the pan on top of the butter.

dredge bread in egg mixture

Combine eggs, milk, vanilla, and cinnamon in a medium sized bowl. Then pour egg mixture over bread and make sure to dredge the bread through the mixture. Place bread in baking dish. Now it’s ready to bake. You can do one of two things – bake at 350 degrees for 30 minutes or cover with plastic wrap and refrigerate overnight.

Side dishes for French toast casserole

Offset the rich custard of the casserole with fresh berries such as strawberries, blueberries and raspberries. Greek yogurt drizzled with honey plays up the creamy texture. Crispy bacon or breakfast sausage offsets the sweetness of the French toast. Keep it simple, yet delicious.

Baked French toast is yummy and super easy to make ahead of time. You deserve to enjoy your mornings, too.

  1. I add diced apples and more cinnamon to my toast ( personal preference), but I don’t know i’ve been denying myself the pleasure of pecans. Thanks for sharing your recipe, using nuts

    1. Hi Laura,
      I have not tried to make this and freeze it. It might work. I would be most worried that the bread would end up soggy, but I don’t really know. If you try it, come back and let me know! 🙂

  2. Why not make things heart and vascular healthy ?
    Using plant based ingredients!
    No sugar,salt or oil.
    Can use maple sugar.
