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 for Success
- 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.
