The Best Overnight French Toast Casserole
Baked French Toast is a quick and easy overnight casserole that tastes amazing and can be made the night before. I’m in love with breakfasts you can make ahead of time and simply throw in the oven in the morning or already have prepared, like Savory Breakfast Bundt Cake, or Make-Ahead Pancake Batter!
Overnight french toast is sometimes called “Baked French Toast”, “French Toast Casserole” or “Company French Toast” and it’s the perfect breakfast to make when you want to have something special to serve for breakfast but you also want to relax and enjoy the morning. We enjoy this east breakfast regularly, but this is always a staple for any holiday breakfast in our home. We also make this any time we have guests and they always rave about this dish every time!
Ingredients You Will Need
You won’t need any fancy ingredients for this breakfast casserole. In fact, I bet you have most of these things in your kitchen already! Here’s a quick overview of what you’ll need. Be sure to scroll down to the recipe card for specific amounts.
- French Bread – you can also use texas toast, challah, or brioche.
- Eggs – you will use 8 eggs to make the base for the custard.
- Half and Half – you can substitute whole milk for the half and half if need.
- Milk – whole milk is preferred for this recipe, but you can use 1-2% with fine results.
- Granulated Sugar – this is added to the egg mixture for just a hint of sweetness.
- Vanilla – make sure you use pure vanilla extract.
- Ground Cinnamon – the cinnamon is added to the custard mixture and the topping and gives such a nice flavor.
- Nutmeg – we use ground nutmeg for this recipe, but freshly grated nutmeg is always a nice touch if you have it.
- Butter – this is combined with sugar to make a nice cinnamon crunch topping.
- Brown Sugar – The brown sugar will add a nice caramelized glaze to this french toast.
- Corn Syrup – the corn syrup is actually optional, but we think this gives the topping a very nice consistency. However, you can leave this out with great results.
How To Make Overnight French Toast
One of the best things about this breakfast casserole is how easy it is to make – it only takes minutes! Here’s how to do it:
- Arrange your bread slices in a prepared 9×13.
- In a medium bowl, whisk together eggs, half & half, milk, vanilla and spices. Pour the mixture over the slices making sure all of them are coated well.
- Refrigerate overnight or for at least 4 hours before baking.
- When ready to bake, combine the topping ingredients and spread over the top. Bake at 350 for 35-40 minutes.
Can you make overnight french toast the same day?
Yes! If you want to bake the french toast right after you make it and don’t want to wait overnight, just make the custard and dip the bread into it letting it soak before placing the bread slices into the pan and baking. Pour any remaining custard over the bread after you have placed it in your baking dish, then cover with saran wrap and place in the fridge for 2-3 hours (the longer the better). This will give the custard time to soak into the bread even though we have sped up the process somewhat by dipping the individual bread pieces into the custard before placing them in the baking dish.
Pro Tips and Tricks
- Texture: This is a french toast casserole so parts of the slices will be soft and the tops with a more baked/crisp texture. If you prefer the slices to a more baked/crisp texture, use a larger pan (deep half sheet cake pan) and this will open up the slices instead of packing them in a 9×13. Another option is to use two 9×13 pans.
- Slices: Sometimes I have used sliced sour dough bread from the bakery and that works great. This will save a little time from having to cut a loaf.
- Forgot to make the night before? That’s totally fine. I have done this as well. Just make sure the slices are soaked up really well and proceed with directions.
- Want to add some crunch? You can add chopped pecans to the cinnamon crunch topping for a praline topping. Add in 1 cup of chopped pecans.
- Add fruit: This french toast casserole is amazing served with fresh berries instead of the praline topping if you are looking to lighten it up. We actually enjoy this served with the topping and berries!
How to Store and Reheat Leftovers
- Fridge: Let your casserole cool completely then cover with saran wrap or transfer to an airtight container and store in the fridge. It will keep for 3-4 days.
- Reheating from the fridge: When you are ready to eat another slice of french toast casserole simply place your desired amount on a plate and zap it in the microwave until warmed through. I usually will cut a large piece of french toast into smaller pieces so that the insides heat evenly.
- Freezing: The leftovers freeze VERY well! Place any leftovers in an air-tight, freezer-safe container. It will keep for up to 3 months.
- Reheating from frozen: When ready to eat, just thaw it and pop it in the oven at 350 for about 10 minutes.

Overnight French Toast Casserole
Ingredients
- 1 loaf french bread or thick texas toast
- 8 eggs
- 2 cups half and half
- 1/2 cup milk
- 3 Tbsp granulated sugar
- 1 1/2 teaspoons pure vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1/2 teaspoon salt
Cinnamon Crunch Topping
- 1 1/2 sticks butter softened
- 1 cup light brown sugar packed
- 1 Tbsp light corn syrup optional
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
Instructions
- Prepare a 9"x13" baking dish by coating the entire inside of the dish with butter or cooking spray. Set aside.
- Slice the French bread, about 1-inch thick. Arrange slices in your prepared baking dish in rows, overlapping the slices. Set aside.
- In a large bowl, whisk eggs. Add half-and-half, milk, sugar, vanilla, cinnamon, nutmeg, and salt. Whisk until well combined.
- Pour the egg mixture over the bread slices, making sure they are covered evenly. Spoon some of the mixture in between the slices making sure all the slices are completely covered. Cover with foil and refrigerate overnight.
- The next day, preheat oven to 350°F. Meanwhile, carefully flip each piece of bread over to make sure everything is nice and coated with the mixture.
Make the Topping
- Combine all ingredients in a medium bowl and mix to combine. Spoon the topping on top of the prepared bread slices. Then spread evenly over the bread (like you are icing a cake). You can also spread some of the mixture in between the slices to make sure the entire slice is covered (if you prefer).
- Bake for 35-40 minutes (no need to cover with foil), until puffed and lightly golden.

This is our yearly tradition when family visits for Thanksgiving and or Christmas ❣️ It’s always awesome ❣️ we use pure maple syrup yummy ❣️
This was awesome!! I added chopped pecans to bread and mixed in with the topping. It got rave reviews!
*I tried giving this a 5 star rating and it wouldn’t let me but I made this on our Alaska trip and everyone absolutely loved it! I’m making it again and hope it turns out just as good as it did then! Thank you for this recipe!!
Are you able to make ahead of time and freeze?
Hi Kris. I have not tried that with this recipe, but if you do try it let us know how it turns out!
My family loves this quick and DELICIOUS baked French toast recipe!! I know it says overnight but this morning it’s what my family wanted sooo I made it. Turn out better than overnight (just in my opinion). I did change it up some by adding homemade Carmel sauce on the bottom of the pan and the a drained can of peaches. What also made this even better was using Brioche bread. My family and I are so grateful for this yummy recipe you have shared with all of us!
Glad to hear it Julie!
I have made this so many times for my husband. Just today when eating breakfast he said I think it’s time for your overnight French toast. He loves it. I love it too, especially because it’s so easy and saves so much time in the morning, just pop into the oven. If you like you can cook some bacon or sausage while the French toast is baking.
My family LOVES this!! I add chopped pecans to the topping because my family loves nuts. I made it for Christmas and again this weekend when we were all together and they all raved again!
I’m confused how much bread should you use. Where I am French bread loaves around a pound, but Texas toast loaves at between 20-22oz
My family loves this!! One of our favorite dishes to have for breakfast.
Delicious, many compliments and now requests I make it again as my contribution towards our family Easter brunch this year. Gave a slice to a neighbor lady she said” on a scale of marvelous to fantastic, you my friend get a triple stupendous!”
Very good. I added a little more cinnamon and nutmeg to the egg mixture
The overnight French toast was a hit with my family and myself. Wow terrific! I cubed the French rolls I had in my pantry and it was so good. Thanks for the recipe.
Made this for Christmas morning. Substituted some eggnog for some of the milk. Everyone loved the extra richness and flavor.
Great! I didn’t make the topping, just served with syrup. Family said the day before not to make it, we had plenty for breakfast. I made half a recipe anyway, and they gobbled it up. Somebody said it’s like bread pudding – no it isn’t, there’s no custard on top, the bread soaks it all up and is quite soft inside.
Huge hit at my granddaughter’s birthday brunch! Made it EXACTLY as stated. PERFECT! THANK YOU!!!
Made this French toast casserole Christmas morning, it was really good but the top got really hard, the recipe didn’t say to cover it and I used French bread♀️
I think I would cover with foil for at least 40 minutes. Then, I’d uncover, and bake it until the top is crispy. I saw someone thought the bread was soggy in places. That just means it needs to bake longer. Everything depends on yield thickness of the bread slices and making sure it is well basted (maybe more than once). I would add maple syrup too instead of corn syrup. I’m trying to avoid that, and maple flavor seems called for.
It turned out great, tasted great and was a big hit every time. I have even taken it to our Easter morning potluck.
I have made this recipe DOZENS of times and everyone loves it.. BUT the end product you show served on a plate in the tutorial video looks NOTHING like what is produced! It’s a CASSEROLE! It is not served at individual pieces of French toast. Just an FYI
So excited to make this for my family!! I love making my family some new things around the holidays. We have a lot of cozy family breakfasts around Christmas and New Year. And the best part is that we recently got our cabinets painted so I get to make all of this yummy holiday food in my new kitchen! Thanks for the recipe – I’m so excited to make it!!
Tried this recipe for a staff morning potluck. It was a super hit! I’m glad I made it. Instead of leaving flat I cut up all the bread and didn’t use corn syrup. Super delicious
