Blueberry French Toast Casserole is a delightful breakfast dish that combines the comforting flavors of French toast with the tart sweetness of blueberries. Perfect for a weekend brunch or a cozy morning gathering, this casserole can be prepared ahead of time and baked fresh for an easy, delicious meal.
Blueberry French toast casserole is the perfect dish for a lazy weekend brunch or a special holiday breakfast. This sweet, baked casserole brings together the classic flavors of French toast with the burst of fresh blueberries, all in one easy-to-make dish. It’s the kind of breakfast that feels indulgent yet comforting, and it’s sure to impress family and guests alike.
The base of this casserole is made with thick slices of bread, ideally a hearty, day-old bread like brioche or challah, which soaks up a rich custard mixture made from eggs, milk, cinnamon, vanilla, and a bit of sugar. This custard makes the French toast casserole custardy in the middle while allowing the top to become golden and crispy after baking. The blueberries add bursts of natural sweetness and tartness, creating the perfect contrast to the rich custard.
To make the casserole, simply layer the bread in a greased baking dish, adding fresh blueberries between the layers. Pour the egg mixture over the bread, ensuring that each slice is soaked well. For added flavor, you can sprinkle a little cinnamon and nutmeg on top. The casserole can be baked immediately, or you can cover it and refrigerate overnight, allowing the bread to soak up the custard even more for a richer, more flavorful dish.
Once baked, the casserole becomes golden brown on the top and soft and custardy inside. The combination of blueberries and custard is irresistible, and the dish is even better when served with a dusting of powdered sugar or a drizzle of maple syrup. You can also add a dollop of whipped cream or a handful of extra fresh berries for a little extra indulgence.
Blueberry French toast casserole is an easy, make-ahead breakfast that doesn’t require a lot of hands-on time, making it a great option for busy mornings or special occasions. It’s the perfect balance of sweet, savory, and satisfying, making it a breakfast favorite that everyone will enjoy.

This was so good! My family loved it, especially the blueberries. Will make again!
This was a hit at our brunch! Super easy to make and sooo delicious!
Made it for my kids and they loved it! Blueberries are a hit! 💙
I don’t know… sounds kinda heavy for breakfast. But glad your kids liked it!
That’s awesome! Blueberries really make everything better. 😊
I found it a bit too sweet for my taste. Maybe less sugar next time?
This was a hit at our breakfast gathering! The blueberries really pop in this dish.
Could you use any bread? I don’t have French bread. Maybe I’ll try with whole wheat?
Yeah, whole wheat should work fine! Just might change the flavor a bit, but should still be tasty.
Isn’t this just bread pudding? Either way, I’m down. Yum!
This was a hit at brunch! Everyone loved it. I’ll definitely make it again.
It was okay, but a little too sweet for my taste. Maybe reduce the sugar next time?
I get what you mean! It was sweet for me too. Maybe try using less sugar next time or a sugar alternative. Just a thought!
I don’t know about this one. Seems like too many eggs to me.
I think the eggs are what make it rich and creamy! Can’t wait to try it!
8 eggs? That’s overkill! How can it not be an egg soup? 🤔
The instructions were confusing! Do I really need to let it sit for that long? 🤔
Why do you put it in fridge for so long? I just baked it right away. It turned out fine. IDK what the fuss is about.
Honestly, I was skeptical about the blueberries with french toast, but it actually tasted good.
I was the same way! Never thought blueberries would go with French toast, but it was a game changer for sure!
Casseroles are hard, but I think I can do this one. Wish me luck! 🤞
You got this! Casseroles are easier than they seem. Just take your time and follow the steps! 🍽️
Delicious! But I only had a very old loaf of bread, and it still worked! Haha!
Blueberries and French toast? Genius! I added some nuts on top for a crunch, yum!
Blueberries in french toast? Kinda weird, don’t you think? I mean, I like blueberries but not on toast. Gonna pass on this one.
That sounds delish! I love adding nuts too, gives it a whole new texture. Can’t wait to try this recipe!
Very easy to make. Perfect for a Sunday brunch! Will make again.
OMG, this is the best thing I’ve ever made! Perfect for Sunday mornings. 😍
This is super easy to make! A bit too sweet for my taste, but family enjoyed it! 😊
I dunno, seemed a bit too sweet for my taste. Maybe reduce the sugar next time?
Way too many eggs! It tasted like an omelet with bread. Never again!
Nah, I love eggs! More eggs, more protein. Just adjust to your taste next time.
I thought it was great! The eggs made it really fluffy. Maybe you just had a bad batch?
Yum! But why doesn’t it mention topping it with whipped cream?
Blueberries are good for you, right? It’s basically healthy, so I’m calling it a win!
It was okay, but I think the amount of sugar was too much. Next time, I’ll use less sugar for sure.
Idk, it wasn’t great. Felt like too much bread with not enough flavor. I prefer my french toast solo!
I think the recipe needs more spices or something. It’s meant to be sweet and tasty! Maybe add more blueberries? 🤔
This was delicious! Perfect for brunch with friends. Will definitely make it again!
Glad you loved it! It’s a crowd-pleaser for sure. Just wait until they try it with maple syrup! 😋
Yummy! Could eat this every day. 😍🏅
Looks good, but I ain’t sure about using heavy cream. Seems too rich.
This looks delish! Can’t wait to try it! 🙌
Can I substitute blueberries with strawberries? Asking for a friend! 🍓
Yes! Strawberries would work fine. Just slice ’em up! 🍓
I dunno… Strawberries are sweet, but blueberries make it special. Just sayin’!
I messed up the baking time and it came out soggy. I guess it was my fault.
This is the best! I made it for Mother’s Day and she was so happy. Thanks for sharing!
Sounds good, but isn’t it a bit too rich with all those eggs and cream? I prefer lighter breakfasts.
That’s so sweet! I’m sure your mom loved it. I want to try this for my family too!
Yum! Blueberries! Makes me wanna dance. 🕺💃
Just made this and it was an epic fail for me. My eggs didn’t set at all. Not sure what I did wrong.
Ehh… tasted fine but my kids refused to eat it. I guess they’re picky. 😒
Came out burnt on top, but still tasty. Maybe lower the temp next time?
This casserole is absolutely delicious! I made it for brunch, and everyone loved it. Will definitely make again!
This was absolutely delicious! The kids loved it and asked for seconds!
Took way longer to bake than you said. My oven must be broken or something.
Maybe try adjusting your oven’s temperature? Sometimes they can be off. But I hope it still tasted good! 🍴
I was skeptical about using heavy cream. Isn’t that unhealthy? But it turned out great!
Heavy cream is definitely a bit of a guilty pleasure, but it adds such a richness! Glad it worked out for you!
My dog loved it, but I burnt the top! 😂 Next time I will watch it better.
Haha, at least your dog enjoyed it! Maybe next time set a timer so you don’t burn it! 🤣
I tried this recipe and it was way too sweet for my taste. Maybe less sugar next time.
Does it have to be fresh blueberries? I only had frozen ones and they were good too.
OMG! Best breakfast ever! I added some walnuts and it was amazing! 🌰✨
Yum! Walnuts sound like a great addition! Can’t wait to try it! 🌟
But aren’t walnuts kinda weird in French toast? I’d stick to just blueberries, maybe even strawberries.
I may have added too much sugar, it was super sweet! Next time, I’ll cut back.
Easy to make, but my bread got too soggy. Not sure if I did it right. 😕
This was so delicious! My family loved it! 💖
It sounds good, but I don’t know if my kids will eat blueberries. They’re picky eaters. 🤨
So glad to hear that! It’s a family favorite in our house too! 😊❤️
Yum! Blueberries are my fav! Best breakfast idea ever!
I thought blueberries are not so good for breakfast… but this rly changed my mind.
I was skeptical too, but this dish is a game changer! Very tasty.
My kids loved it, but my partner doesn’t like blueberries. Guess we won’t be having it again?
I’m not a great cook, but this was sooo simple! Thank you for the recipe!
I dunno, it seems like a lot of steps for just some toast. Can’t you just make regular French toast instead?
I’m glad you found it easy! Cooking can be fun when the recipes are straightforward. Enjoy your breakfast!
Casseroles are so easy but this feels fancy! Can I use other fruits?
Absolutely! You can use any fruits you like, like strawberries or peaches. Just make sure they’re not too watery! 🍑
I dunno, I think it wouldn’t taste the same. Blueberries are the best for this recipe, right? 🤔
Looks complicated but I tried it and it was pretty easy! A little sweet though, I might cut down on the sugar next time.
Not what I expected. The texture was kinda mushy. Maybe I let it sit too long?
I substituted strawberries for blueberries and it turned out great. Just saying!
I didn’t have heavy cream so I used yogurt. Still turned out okay but I think it would be better with cream.
Way too much sugar for my taste. Healthier options would be better.
