You will need a whole loaf since it is intended to serve eight (it can serve up to 12 if you really push it!). With this recipe, you can serve a crowd without standing over the oven, pan frying each individual piece of toast.
Other ingredients you will need are:

- Milk
- Butter
- Maple syrup
- Icing sugar
- Berries
How to make French toast casserole
This overnight French toast casserole is perfect for a holiday brunch because you can prepare most of it in advance and just finish cooking it the morning you want to serve it. Here's how to make it step-by-step:
- Cut bread into one to two inch cubes.
- Whisk eggs, milk, maple syrup and cinnamon together.
- Add the bread cubes to the liquid and gently toss until they are covered.
- This is the point at which you can stop for meal prep. Continue if you want to make and eat it immediately. If you are preparing it in advance, refrigerate the soaked bread cubes for up to 12 hours or overnight.
- When you are prepared to bake it, put the bread cubes in a greased pan and top with berries.
- Bake for 30 minutes.
- Add toppings and serve!
What type of bread is best for French toast?
Any bread aisle has hundreds of choices for bread. We all have a favorite for sandwiches or toast. These are the most highly recommended for French toast:
- Brioche – The thickness of this bread makes it a perpetual favorite. It soaks up all the liquid while cooking but still maintains its shape. The outside browns nicely in the oven while the inside is soft and delicate.
- Challah – It’s very similar in texture to brioche so it soaks up the liquid and keeps its shape. It has a buttery flavor, enhancing the taste of the finished baked French toast casserole.
- French bread – This is a great option if you plan to let it soak overnight. The texture is a little more chewy so it’s nearly perfect after a longer soaking time.
If you are having trouble finding any of these, choose a bread that you can buy as an uncut loaf. That way you can make the cubes instead of working with thin slices. Always leave the crust on so your end product has nice crisp edges.
Sandwich bread will get soggy if it sits for too long, so shorten your soaking time if you plan to use that – only 10 minutes tops. You can use it for this recipe though, and that is often the easiest choice! Stale break does keep its shape better, but won’t soak up as much of the liquid.
Making it ahead for overnight
It’s easy to make this dish in advance. Cut the bread and prepare the liquid mixture. Once the bread is in the egg and milk, allow it to soak as long as 12 hours.
You’ll only need about 30 minutes for hands-off cooking before you want to serve this. If you have refrigerated it overnight, it may need another five minutes in the oven to finish cooking.
What to serve with French toast casserole
Other breakfast foods are natural sides for this French toast casserole. Try some of these if you're serving a large crowd – at this point you can divide the servings into 12 portions and then have some extra protein or side dishes available to feed everyone.
- Bacon

Ingredient substitutions
If you need to omit the eggs or milk to accommodate allergies or a vegan guest, you can use coconut or almond milk and tofu or a flax egg. Pumpkin puree and mashed bananas are other substitutes you could use for the liquid component of this baked French toast casserole.
If you wanted flavors other than cinnamon, you could use any of these spices:
- Pumpkin pie spice
- Nutmeg
- Vanilla extract
- Ginger
- Cloves
- Orange or lemon zest
You can even try a cinnamon or raisin bread for a unique twist on this casserole. You could use sourdough bread if you want to balance out the sweetness.
Topping ideas
Fresh berries are a healthy and delicious topping idea for this French toast casserole. Some other things you can make available for topping choices include:
- Maple syrup
- Icing sugar
- Lemon curd
- Nutella
- Bananas
- Peanut butter
- Honey
- Applesauce
- Yogurt
- Jam
- Dried cranberries
Storing and reheating
This baked French toast casserole can be stored in the refrigerator for five days.
To reheat, I recommend you take the time to warm it in the toaster oven or conventional oven. The microwave will make it soggy. It will take ten minutes to completely reheat in a 350 F oven.
You can also store leftovers in individual portions in glass meal prep containers and microwave for 1-2 minutes until warmed. It will be soggier than if reheated in the oven, but if you like the softer pieces like I do, then go for it!
Can you freeze French toast casserole?
You can freeze this casserole, but I suggest you do so without the berries. They contain too much water and will soak your bread.
French toast casserole can be frozen for one to two months. You can reheat this directly from frozen in a 350 F oven for 30-40 minutes.

Darlene P George says
Can you use frozen thawed berries? Perhaps drain the juice if that would help? It is sometimes really difficult finding fresh raspberries, strawberries and blueberries in the winter especially around the holidays. Our family always starts Christmas with a big “Christmas Breakfast”, it’s tradition. Our children and grandchildren would love with those berries it in, with them being their favorites. It looks delicious but I can’t see them getting as excited and wanting to give up something we usually make unless they get the berries with it.
Taylor Stinson says
Yes of course Darlene, you can just use all frozen berries! Defrosting and draining the juices to put on top would be perfect 🙂
Darlene says
Best French Toast ever!! I use Brioche dinner rolls, taste very good.
Taylor Stinson says
So happy you enjoyed 🙂
Ginger Clemens says
Followed directions as written but added 1 tsp vanilla and about another half cup of frozen berries. I used regular French bread and let it soak over night. Cooked longer than 30 minutes, til pick came out clean. Served with strawberries and maple syrup. This is absolutely delicious and so much easier than making French toast for 6 people.. I’ll definitely be making this again! Thanks for a great recipe.
Taylor Stinson says
I’m so happy you enjoyed!
Abigail says
Hi, approximately how many cups of bread should I have when making this recipe? Looking forward to making this for Sunday brunch. 🙂
Taylor Stinson says
Hi Abigail – it is one loaf of bread. Unfortunately I cannot give out measurements in cups but if I had to guesstimate, it would be about 10-12 cups.
Eryka says
We have made this for the past 3 holidays and are making again this Christmas! We love this recipe for as a part of our big brunches, and its a bonus that the vegetarians can enjoy it too!
Charlie says
Is icing sugar the same thing as confectioners sugar?
Taylor Stinson says
As far as I’m aware, yes it is!
Amy says
Can you use wheat bread or would it not be as good?
Taylor Stinson says
Hi Amy – I honestly don’t think it would be as good but it just depends on your own personal preference. You can totally use it if you’d like!
Joyce says
Made this for my grandchildren a couple weeks ago and they absolutely loved it. Of Course I did do brown sugar flower butter topping, did that for the kids but it would still be great without it
Candace Wilson says
When preparing this to be frozen, do you let it soak before you freeze it? Also when you are ready to cook it, should it be unthawed before doing so or is ok to cook frozen?
Taylor Stinson says
Hi Candace – you can freeze the leftover cooked casserole but not before it has been cooked.
