This Lighter French Toast Casserole can be stored overnight and cooked fresh in the morning – serve with berries and maple syrup!
Ingredients and substitutions
- Loaf of bread – brioche, challah and French bread are the best options. Regular sandwich bread will work, but make sure you only soak it for 10 minutes.
- Eggs – use a flax egg for a vegan option.
- Milk – swap out for a dairy-free milk of your choice like coconut or almond milk.
- Maple syrup – you’ll need maple syrup for that authentic French toast flavour but in a pinch, feel free to use honey or brown sugar.
- Cinnamon – try out other flavours like pumpkin pie spice, nutmeg ,vanilla, ginger, cloves, orange or lemon zest.
- Butter – or a butter substitute of your choice.
- Frozen mixed berries – use any blend of berries you like. You could also use fresh berries if you have some on hand.
Toppings
- Icing sugar – leave this off if you don’t have any on hand.
- Maple syrup – honey, almond butter or jam would all be good toppings.
- Fresh berries – use any berries of your choice like strawberries, raspberries and blackberries.

What type of bread is best for French toast?
The bread aisle has hundreds of choices for bread and we pretty much all have a favourite when it comes to sandwiches or toast. Wondering what kind of bread to use for this delicious breakfast dish? These are the most highly recommended kinds of bread 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 flavour, enhancing the taste of the finished baked French toast casserole.
- French bread – This is a great option if you plan to let your casserole soak overnight. The texture is a little chewier 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.
Frequently Asked Questions
If you find that your French toast casserole is soggy, you likely used sandwich bread, which gets soggy if it sits too long in the liquid mixture. I suggest using brioche, challah or French bread if you plan on making this casserole the night before so it doesn’t get soggy! If all you have on hand is regular sandwich bread, limit the soaking time to no more than 10 minutes.
Fresh berries are a healthy and delicious topping idea for this French toast casserole. Some other things you can top your French toast with are lemon curd, Nutella, bananas, peanut butter, honey, applesauce, yogurt, jam and dried cranberries.
Other breakfast foods are natural side dishes for this French toast casserole. Try serving it with bacon, fresh fruit, sausage, eggs or home fries if you're serving a large crowd. You can divide the servings into 12 portions and then have some extra protein or side dishes available to feed everyone. It’s the perfect dish for Christmas morning or big brunches!
Storing and reheating
This baked French toast casserole can be stored in the refrigerator for up to 5 days right in the casserole dish or in glass containers.
To reheat, I recommend you take the time to warm up the casserole in the toaster oven or a conventional oven for 10 minutes at 350° Fahrenheit. You can microwave it for 1 to 2 minutes, just keep in mind that the bread will be soggier – but if you like your French toast softer, then go for it!
Can you freeze French toast casserole?
You can freeze this French toast casserole for 1 to 2 months, but I suggest you freeze it without the berries. They contain too much water and will soak your bread. When you’re ready to enjoy, reheat the casserole directly from frozen for 30 to 40 minutes at 350° Fahrenheit.

Comments & Reviews
Cyndi says
This has become a holiday weekend/guest staple in our house. Everyone enjoys it and it looks incredibly festive. My son only likes strawberries so we modify it and sometimes just do strawberries on 1/3 and blueberries and strawberries on the rest. It reheats nicely, making for a yummy breakfast all weekend even for a small family. Love this recipe!!! Thank you!!!
Taylor Stinson says
I’m so happy it’s a favourite! 🙂
Kathleen Harris says
This was so yummy and easy to make. Was a big hit for Easter breakfast that everyone wanted more of. Will definitely be making this again.
Taylor Stinson says
I’m so happy you enjoyed!
Diana says
This was a hit with my family for Christmas and I also took it to work. Everyone loved it! I sprinkled pumpkin spice on top once I had poured the melted butter and I used a cube of melted butter. It was so yummy, fresh and light which everyone loved!
Taylor Stinson says
I’m so happy you enjoyed!
Shasri says
I would like to try this for my family breakfast. I just want to make sure that I could actually prep it the night before (without the fruits and melted butter added in until ready to bake right) and bake it in the morning correct? Would it be soggy if I did it this way though?
Taylor Stinson says
No it wouldn’t be, you can definitely do this the night before!
Emma says
I am going to be trying this with gluten free bread, but gluten free bread loaves are much smaller than regular bread. About how many cups of cubed bread would this recipe call for? Thanks!
Taylor Stinson says
I think it would be about 8 cups!
Patty says
I can’t wait to make this for “Girls Weekend”!
Do you know the serving size? There will be 8 of us, but I want to be sure there’s enough. Should I go ahead and make 2, to be safe, or are they generous portions?
Taylor Stinson says
The recipe serves 8 🙂 We regularly make it for Christmas brunch for a crowd and it’s just the right amount of food – if I had to guess it’s about a 1 cup serving each. If you serve with some sausages and fruit on the side, it’ll be more than filling.
Nancy says
I was wondering if you thaw the frozen fruit before putting them on top?
Taylor Stinson says
I add the frozen fruit before baking then add fresh fruit on top!
Jo-Ann says
My first recipe from The Girl on Bloor, and it was a huge hit with my family. I’m an early fan now and looking for more delicious and healthy options. Thank you!
Taylor Stinson says
Aww thank you so much! I’m so happy you enjoyed 🙂
Barbie says
If using fresh berries, would.you place on top after cooking or incorporate and then bake?
Taylor Stinson says
I would add them afterward 🙂
Liz M says
I just want to confirm that it is supposed to be baked with the fruit on it?
I am making this for a work breakfast and wanted to be sure. Also can it be made in a glass Pyrex dish!
Taylor Stinson says
Yes it is! If you don’t like that much fruit you can leave it out and just top with fresh fruit if you’d like. And you will need to check that your baking dish is oven safe – I know different types of Pyrex are oven safe and others aren’t, it should say whether it’s oven safe right on the dish itself.
