Would you believe me if I told you, you could make an easy breakfast to feed a crowd, prepared the night before, that will leave your whole house smelling like legit cinnamon rolls? Based on these photos, I hope you believe me because this overnight French toast bake is the real deal.

It taste just like cinnamon rolls, but it’s so easy to prepare! The hardest part is waiting for this dish to cook long enough before you can dig in. Plus, it can be made gluten-free, dairy-free and refined sugar-free.

Ingredients for Overnight French Toast Bake

  • White Bread (we used gluten-free, but use what you need to!)
  • Milk (we used almond milk to keep it dairy-free)
  • Eggs
  • Coconut Sugar
  • Cinnamon
  • Butter (or ghee, or coconut oil for dairy-free)

We also topped this French toast with a dairy-free glaze made from cashew cream and maple syrup. It was heavenly. You could also top it with a standard powdered sugar glaze by mixing together powdered sugar and a place of milk, until it’s reached the consistency you’d like.

How to Make a French Toast Casserole?

It really could not be easier!

  1. You cube up some bread. It’s best if you can either do this ahead of time, and leave the bread out to dry out, or you can toast the bread in the oven beforehand. This step isn’t absolutely essential, but it improves the texture of the final dish, especially if you are using gluten-free bread.
  2. Next, you place half the cubed bread cubes in a greased 9×13″ baking dish. We love using it in our Ello DuraGlass Bakeware Containers because they have a matching lid that makes this the perfect prep, bake and serve container for an overnight French toast.
  3. Then you sprinkle a cinnamon roll sugar mixture over the bread crumbs.
  4. Top that with the remainder of the bread cubes.
  5. Next, pour over a mixture of eggs and milk and push down on the bread cubes to make sure all of it gets in contact with the milk.
  6. Sprinkle the remaining cinnamon sugar over the bread. Then cover the dish and let rest overnight!
  7. When you are ready to bake in the morning, preheat the oven and pop the lid off the bakeware. Place in the oven and bake until cooked through.
  8. And finally, drizzle that cinnamon roll french toast for a more authentic look and taste.

Do You Need to Prepare This Overnight?

Casseroles are a perfect make-ahead dish. This French toast casserole tastes better when the bread has a chance to soak up the egg and milk mixture. We did test this baked right after preparing the dish and it still tastes great, but not all of the custard is absorbed at that point, so you will notice some of it baked up in the dish.

We do recommend you prepare it the night before, though in a pinch, it can be baked right away. We know this is the perfect holiday brunch dish because there are two ways to prep for it ahead of time.

  1. This dish is obviously prepared the night before. You can either bake the dish at home for guests, or snap on the lid and bake it fresh at your destination. This is a good option if you are traveling with this dish, but want to eat it freshly baked.
  2. Or you can fully bake this dish and reheat. This entire dish can be prepared fully, except for the glaze, cooled completely and then stored in the refrigerator, for up to 1 day, until ready to serve. Reheat the dish in a warm oven until heated through. Then drizzle it with the glaze.

Store It

  • Store in the refrigerator, for up to 1 day, until ready to serve.
  • Reheat the dish in a warm oven until heated through. Then drizzle it with the glaze.

  • 21/2 cups milk-of-choice (we used almond milk)

  2. Mix together coconut sugar, 2 teaspoons cinnamon and softened butter together in a small bowl until crumbly.
  3. Grease a 9×13 baking dish. Place half of the bread cubes in the greased pan. Sprinkle ⅓ of the cinnamon sugar mixture on top. Top with remaining bread cubes.
  4. Whisk together milk, eggs and 1 teaspoon cinnamon in a large bowl. Pour evenly over the top of the bread cubes. Using your hands, push down on the bread cubes to make sure they come into contact evenly with the milk.
  5. Sprinkle the remaining sugar mixture over the top of the bread cubes. Cover and let sit, refrigerated, overnight.
  6. When ready to bake, preheat the oven to 350ºF. Bake in the oven 35-40 minutes, until set.

  1. This was perfect for Christmas morning – thank you Lexi! I added toasted pecans but otherwise followed it to a T – so easy with big cinnamon roll flavor!

  2. Made this for brunch for my son’s 18th birthday today and it was a big hit! The texture and flavor are perfect. So easy to put together too. This will be forever in my brunch “must haves” now. Thank you Lexi!

  3. I’m making this for a work party. I planned on making it the night before, and baking it in the morning. However, my dish is a bit smaller than 9×13, and I’m afraid that the egg mixture will make the bread soggy if I leave it overnight.

    1. Hi Kaylee–the bread will get soggy no matter what the size dish–it’s supposed to. The bread soaks in the eggy mixture and than bakes up with it, almost turning the bread into a custard. But since your dish is a slightly smaller than a 9×13, I’d suggest maybe pouring over slightly less of the eggy milk mixture.

  4. This was fantastic! Made it last night, baked it this morning and what a delicious texture and flavor!! Another win Lexi!!
