Overnight Blueberry French Toast Casserole

A French Toast Casserole studded with fresh blueberries, which is super easy to prepare and topped with warm homemade Blueberry Syrup.


Hi! How was your weekend?

I thought I’d post this recipe today to savor the weekend a little bit longer. We had a jam-packed couple of days including tackling some projects around the house, squeezing in a couple of runs and going on a fun date together. Time sure seems to be flying by when the weather is improving and you can finally step outside without having to worry about frostbite or slipping on a piece of ice.

Late Friday night, I decided that we would be enjoying our much loved Blueberry French Toast the following morning. Never mind that it was getting kind of late since this breakfast casserole can be whipped up in mere minutes.


I didn’t really have any intentions of posting this recipe. Not because I didn’t want to share it, but this recipe has been around for so long now, that it simply didn’t occur to me to put it on the blog. Until I pulled out the recipe and realized that the original is nothing like the one I use now to make this casserole. It has undergone many changes over time, all of which were stashed in my memory. So I proceeded to write everything down step-by-step and was holding the perfect recipe to share with all of you!


This casserole definitely falls into the oldie but goodie category. There are many reasons why this is a family favorite, but the best part is that it requires almost no work the following day. I am all about spending as much time as possible with my loved ones instead of in the kitchen.

There is nothing like sitting down for a meal and enjoying every minute of good food, good conversation and perfect company. Sitting down for a meal is really important in our house. Both my husband and I eat supper together pretty much every night at our dinner table. It’s something we have done since day one of our marriage and still look forward to the most each and every day.


As soon as this dish comes out of the oven, the entire family will be able to enjoy a delicious meal together.

Not only does it make for a nice presentation with perfectly toasted French bread pieces and caramelized blueberries on top, but it tastes even better. This French toast casserole is crunchy, fruity, sweet and has a soft & creamy middle. It comes out just right every time.


I happen to think that this is the quintessential breakfast or brunch food or if you’re anything like me, this is more than appropriate for dinner as well :).

We top our French toast with a fabulous homemade Blueberry Syrup. Making the syrup is completely optional as you could totally serve this with regular syrup or even powdered sugar instead. But if you love blueberries or fruity syrups, this one is for you. And a must-try if you’ve never had it before.


Alright, friends. Hope you have a great start to your week!!

For the Blueberry French Toast Casserole
  1. 1 1/2 loaves French Bread, cut into cubes
  2. 4 oz. cream cheese
  3. 1 tablespoon milk
  4. 1/2 cup powdered sugar
  5. 1 cup blueberries
  6. 1 cup milk
  7. 5 eggs
  8. 2 teaspoons vanilla extract
  9. 1/2 teaspoon cinnamon
  10. 1/4 teaspoon nutmeg
  11. 1/4 cup maple syrup
For the Blueberry Syrup
  1. 1 cup cold water
  2. 2 tablespoons corn starch
  3. 1/2 cup sugar
  4. 1 cup blueberries
  1. 1. Spray an 8-x-8 inch casserole dish with nonstick spray.
  2. 2. Spread half of the French Bread cubes in an even layer over the bottom of the casserole dish.
  3. 3. Mix together cream cheese, milk, and powdered sugar until well combined. Mixture should be somewhat thick and not watery. Add more powdered sugar if mixture seems too thin. Pour over bread cubes and sprinkle with blueberries.
  4. 4. Add remaining bread cubes over the top.
  5. 5. Combine 1 cup milk, eggs, vanilla, cinnamon, nutmeg and syrup. Pour mixture over bread cubes and sprinkle with additional blueberries. Cover with foil and refrigerate overnight.
  6. 6. Remove casserole from fridge 30 minutes before baking. Preheat oven to 375 degrees F and bake covered for 45 minutes. Remove foil and bake for another 30 minutes or until the center is set.
  7. 7. During the last 10 minutes of baking time, prepare the blueberry syrup. In a small saucepan, combine cold water, corn starch and sugar. Heat mixture and bring to a simmer. Add blueberries and continue simmering for 10 minutes. Serve casserole with warm syrup immediately.
  1. Syrup can be made ahead of time and stored in the fridge until needed. Simply reheat in a microwave until warm.
  2. Casserole is best enjoyed served immediately, but can be stored in the fridge for 2 days.
  3. You can substitute frozen berries. Also, you can use any type of berry you prefer.

  1. I wish I had this for breakfast right now! I haven’t made an overnight breakfast before-Gavin doesn’t eat breakfast so I will have to wait until we have company over!

    Thanks for another great recipe!

    • Thank you so much, Helena. This would be the perfect thing to make for when you have company over. So easy and super delicious. Hope you enjoy!!

    • Hi, will this serve 7 hungry people? After I made it it looked smaller than I expected. Thanks!

    • you could always have Breakfast for supper, we have it sometimes esp. if we’re having friends over and we want something different. it’s always nice to suppries them with something different.

  2. Kathi, blueberry anything is my favorite. It’s so nice to make an overnight dish, cause then in the morning you can eat something fabulous without spending a couple hours doing it (even though that is nice sometimes!) Nice addition with the cream cheese…and blueberry syrup is the best, especially when you make your own. Pinned for later. Thank you dear, enjoy Monday!

    • Thank you so much, Kelly. I totally agree – spending a couple of hours in the kitchen is nice once in a while and something I absolutely love doing. That’s why I’m always so surprised that something easy like this casserole can be so good. Blueberries are definitely the star in this dish – you’d really like it :).

  3. You have me drooling over here Kathi! If I made this the night before, I wouldn’t be able to sleep in the next day because I would be so excited about waking up and popping this in the oven. Sounds delicious!

    • Awww, thanks Natalie. We were pretty excited to wake up the next morning. Hope you get to make this sometime – it’s really yummy ๐Ÿ™‚

  4. This french toast casserole is the king!

  5. My husband and I also sit down at our dining room table almost every day to have our meals together. It’s the one time of the day we can just TALK, although I think it might be hard to talk with all the shoveling I’d be doing with this french toast casserole! It looks awesome!

  6. Wow, this looks so good and I bet it smells amazing coming out of the oven too! About once a week I have pancakes for dinner, so I would definitely say this could be eaten at any time of the day!

    • Good to know we’re not the only ones who love breakfast for dinner!! You are so right – this casserole makes your entire house smell amazing. Thanks, Brooke!

  7. This french toast casserole would bring me so much happiness in the morning! What an amazing job! <3

  8. Oh wow! I totally want this for breakfast! Or, in this case, I’d eat it for dinner right now!! Such pretty photos Kathi (as always!) Pinned ๐Ÿ™‚

  9. This truly is a sight for sore eyes on a Monday. What a lovely way to start (or end) the day! Very lovely photos too!

  12. Kathi, you had me at French toast. I am so excited to prepare this for tomorrow morning. My daughter was just asking for a new breakfast idea this morning. I know my family is going to love this

  13. Ah, two of my favorites combined into one dish! I would love to have this for breakfast. Better yet, I would love to wake up and have this ready for me ๐Ÿ˜€

  14. Kathi, I am coming over RIGHT NOW! LOL This looks amazing and I can’t wait to make it this weekend when family comes to visit! Pinned ๐Ÿ™‚ ๐Ÿ™‚

  15. Kathi, when are you moving to LA so we can be BFF and throw amazing brunches together? Seriously, this is everything I love. I’m a bread pudding fanatic and this is basically bread pudding that is appropriate to eat in the morning–um, yes please!

    • Ha! I wish, Elizabeth!! You are so right. This is bread pudding in disguise, so you can have an excuse to eat dessert for breakfast :). I like the way you think, lady!!

  16. You just took the cake on overnight dishes. So, this is this weekend’s meal, because I have been trying to find an overnight french toast that appeals to me. This is it!! Thanks Kathi!

  17. Love overnight casseroles, easy peasy! My boys are HUGE blueberry fans, so I’m certain they would devour this. It looks amazing!

    It’s true that time flies when the weather gets nicer. Finally! I’m getting ready for the biggest garage sale in the history of the universe, and it’s amazing what a little bit of sunlight and fresh air can do for my motivation!

    • Thanks, Ashley!! I have been so motivated as well – I forgot how good sunshine feels, ha. Hope your garage sale turns out great. I love going to a couple every year and wish I could visit yours!

  18. What a gorgeous french toast casserole! Love the double-dose of blueberries!

    • Thank you so much, Allie. I can’t even tell you how happy I am that Spring is finally here with all its abundance. Also, thank you so much for pinning!!

  20. ish just got REAL. this is literally perfect for Easter brunch, I am drooling mama!! pin pin pinned ๐Ÿ™‚

  21. Brigitte says:

    This recipe looks fantastic! I’m wondering if you think I could make it way ahead, and freeze for later use. I’d like to take it away on vacation with us, and if it’s already made, it’ll be a lot easier. If I did make it ahead, should I freeze it after the initial baking, or cook it all the way through, and then freeze.

    • Hi Brigitte,
      I would definitely cook it all the way through and then freeze it. Simply thaw it out an hour or two beforehand and bake it until fully heated through. I would guess 20-30 minutes should be sufficient. Hope you have a great trip!!

  22. Kathy, thank you for sharing your recipe. I made it today for Mother’s Day, and it was a complete hit, I whip some cream to go with it. For sure will make it again.

  23. I was wondering if this could be cooked overnight in the crockpot? Thanks.

    • I am not sure. Never tried it, but I am thinking it could totally work. Let me know how it turns out if you give it a go – I’d love to hear!

  24. Made for Sunday breakfast. But modified. An 8×8″ pan was too small. Used 9×13″. One cup of milk was not enough, increased to 3. Might add another egg next time. Only cooked 30 minutes covered, then 15 uncovered. Syrup was delicious. Will double next time. Family loved it. Easy even with my modifications. ๐Ÿ™‚

  25. I want to use a different bread, about how many cups of bread cubes should I use? Thanks in advance!

    • Did you try this with different bread Brandi? I want to make this tonight for a woman’s breakfast tomorrow but I have regular white bread I didn’t realize it was french bread I needed.

  26. Pinned! Can’t wait to make it!

  27. i wonder if this could be done in a slow cooker
    As i dont have an oven?

  28. this looks and sounds so, so good! I’d love to do it for Christmas morning, but my niece is allergic to eggs. I’ve never done a breakfast casserole of any sort without them…thoughts? Thanks!!

  29. Made this for my teacher’s breakfast. It was a huge hit. I doubled the recipe and made it in a 13 x 9 pan. It was the only dish the principal asked about! YuM i think i am going to make it for Christmas breakfast.

  30. How packed should the bread be? I’m thinking there’s no way I’m going to fit 1 1/2 loaves in my 8×8. Do French Bread loaves come in standard sizes? (Seriously, I have no idea ๐Ÿ™‚

    • Autumn Choka says:

      Same thing happened to me. I had to double the egg and milk mixture and it still looks like it’s barely going to be enough.

  31. Can I make it 2 nights in advance? Want to have it Christmas morning, but we will not be home Christmas Eve to prepare it.

  32. Mmmm! Ours is in the oven right now. Best Christmas Eve breakfast ever!

  33. Thanks so much for this recipe! We had it for breakfast Christmas morning and we are sure it’s our new tradition!

  34. WOWZA!

    I just saw this on Huff Post.

    So making this for New Year’s Day!

  35. Can I use buttermilk instead of milk? Thank you, excited to make this!

  36. I’d suggest delineating which ‘milk’ (cup or teaspoon) in your recipe. I know you have it in order, but it could be more straightforward.

  37. Do you by any chance have the measurements for a larger dish? Maybe a 9×13? I am needing to feed quite a few people, and I want to have enough! Looks amazing!

  38. We’re expecting my sister in-law over for Sunday brunch so I decided to give the Blueberry casserole a try. If it’s a success I’m going to make it for our next Lady’s breakfast at church. I will post later on how it turned out. Thank you God Bless.

  39. will have to let everyone know how my casserole turned out I’ve made it tonight for Sunday morning breakfast before Church.. will post later how it was.. Looking forward to trying it..

  40. This AMAZING!!!! I’ve made it 2 days in a row because my family loved it so much, if it was up to the kids we would eat it everyday. THANKS FOR SHARING

  41. I am making this tonight for my birthday brunch tomorrow. I cant wait !!

  42. Two of my favorites combined into one dish! I would love to have this for breakfast. Better yet, I would love to wake up and have this ready for me!

  43. Would you please adjust the recipe to be more specific about the amount of bread needed? Where I live, French bread is sold in loaves that range anywhere from 8 ounces to 1 1/2 pounds. I see from the comments I’m not the only one who is confused. ๐Ÿ™‚ Thanks!

  44. looks delicious, can’t wait to try it for my next brunch. you and i know how to spell our name!!!!!

  45. Do you make 2 batches of syrup? Step 5 syrup is the last ingredient in the list that you pour into the middle of the casserole. Then before serving you make another batch of syrup to pour over top?

    It looks scrumptious!

  46. Can this be done in a crock pot and taken to an early morning meeting?
