Original post..

My husband and his entire family love blueberry desserts!

I used to make blueberry pie all the time but ever since my son was diagnosed with celiac disease and went gluten-free, I have to admit I’m not a huge fan of all the work involved in making a pie crust. (That said, I have been working on one to share with all of you!)

So we started making blueberry crumble and my husband loves it!

It is super easy and just as yummy.

All you need is:

blueberries (we’ve used fresh or frozen wild blueberries)



corn starch

and some lemon juice.

Pro tip:  If using frozen blueberries, we love frozen wild blueberries, they are they smaller ones, and I de-thaw them in a colander in the sink so they drain a lot of water while they defrost.

In the Summer we love making this with fresh blueberries!

And all you do is mix the all the ingredients together in a bowl and pour into your baking dish.

Pro tip: Before mixing them together, I like to fill my baking dish with the blueberries (especially if using fresh blueberries because it’s not messy to do so) and see how they fit…  this allows you to add more or less blueberries to make sure your crumble is full… remember, all fruit shrinks when it bakes.

And you can use any shape baking pan you love or have!

I like to switch it up…. here I used a round pan to make it feel more like a pie…

Then top it with the crumble topping of:

gluten-free all purpose flour (we use GF Jules affiliate link)

gluten-free oats

brown sugar

butter or dairy free butter

and cinnamon.

Back to the gluten-free Blueberry Crumble…

You mix the crumble ingredients together with either a pastry cutter or your hands until well combined.

After you mix all the ingredients, all you do is put the crumble on top of the blueberries and bake!

It couldn’t be easier!

You can also leave the edges without crumble if you want to see more of the blueberries as it bakes!  If you do this however, you might want to bake it on a baking sheet, in case the blueberries bubble over while baking!

You home will smell amazing while it bakes!

Once baked, let cool a bit so that it sets (if might be watery depending on your blueberries, but will continue to thicken as it cools.

Then serve, with or without some vanilla ice cream, and enjoy!

Hope you love it as much as we do!

Blueberry Filling:

  • 7-8 cups fresh or frozen wild blueberries dethawed, depending on size of pan... I tend to use 8 cups.
  • 1/2 cup sugar feel free to use up to 3/4 cup if you want it sweeter or if your blueberries don't seem sweet
  • 1/8 teaspoon salt
  • 2- 3 tablespoons gluten-free all purpose flour or cornstarch
  • 1/4 - 1/2 teaspoon cinnamon depending on tastes
  • 1 teaspoon fresh lemon juice up to 2 teaspoons

Crumble Topping: (This makes a large quantity... Depending on your pan, I sometimes don't need the entire quantity)

  • 1 cup gluten-free all purpose flour with xanthan gum I use GFJules - affiliate link gluten-free flour
  • 3/4 cup brown sugar
  • 1/2 cup quick cooking gluten-free oats
  • 1 stick butter or dairy alternative
  • 1/8-1/4 teaspoon cinnamon to taste


Preheat over to 350 degrees F

    Blueberry Filling

    • In a large mixing bowl, gently mix together all the blueberry filling ingredients.
    • Place in a pie dish of any shape approx 9 inches.

    Crumble Topping

    • Place all ingredients in a medium bowl and mix together with a pastry cutter or your hands until well combined.

    Assemble and Bake

    • With your hands "drop" pieces of crumble over the blueberries until it's covered.
    • Bake at 350° for 40 minutes or until topping slightly golden and blueberries bubbling at the edges. Pro tip: Depending on your oven, check at 35 minutes and if the crumble is getting too brown and the blueberries need to cook longer, cover with foil and continue baking another 5- 10 minutes. Pro tip: I find fresh blueberries often take a little longer to cook... if at 40 minutes it's not bubbling, cover loosely with foil, raise oven temperature to 375 degrees F and bake an additional 5-10 minutes or until edges are bubbling.

      This blueberry crumble was an absolute hit at my family’s Christmas dinner! I almost didn’t make it because I was running out of time, but I am so glad I did! My dad is still talking about this dessert and requests it to be his birthday dessert from now on! So glad it is quick and easy and so thankful for this recipe from Karen!!

    2. This crumble looks awesome! Would I be able to use gf oat flour and maple syrup or coconut sugar as the flours and sweetener respectively? Thinking of using coconut ghee as the butter substitute…. Your guidance and expertise would be so welcome! (Trying to see if i can use what I have in my pantry to make your delicious crumble!) Thanks so much in advance Karen!

      I decided to make this on my birthday and it did not disappoint! It was easy to make and very delicious especially topping it off with vanilla ice cream! Thanks so much Karen for sharing this recipe. The family loves it!

    4. The filling section says “flour or cornstartch”. I assume gluten-free flour? Is cornstarch typically gluten-free?

      Just made this recipe, Blueberry Crumble, with fresh blueberries. I cooked it for 40 minutes, but noticed that it is NOT bubbling up on the sides (I left edges uncovered). It does not seem to be bubbling or juicy at all. I am putting it back in oven, in hopes it just hasn’t cooked long enough, but would welcome your input on this. Hope I haven’t messed it up. Thanks. Oh and it sure does smell awesome.

        1. So, I did this, cooked about 15 minutes longer and it bubbled just a bit. It is now cooling. It looks and smells great. Serving it tonight and hoping it tastes as great as it looks. Will let you know. Thank you.

              Six of us enjoyed the Blueberry crumble. It was a huge hit. Thank you. I will be making this recipe again.

      Many many years ago, a lady made this type of dessert for my family to celebrate my mom having had a baby. I’d never heard of a “crumble”, and it was a wondrous thing to me as a small child and budding foodie who had never seen such a dessert; while I never enjoyed pie for its crust, I DID love a streusel topping and the pie filling. I had made her recipe (by word of mouth) for a while and then…forgot the ratios of the crumble, and after trying other recipes, nothing seemed to be close to what she did. But THIS recipe of yours hit the nail on the head. It’s very good, but I must say…as a streusel lover, I made 1.5 of the amount for the topping. As written it wasn’t enough for me. 🙂 I’m now making this a second time and will need to go picking again because I’ve used up all my berries!! Thank you for sharing your recipe.

      This crumble was amazing! We used our freshly picked blueberries. The topping is so good—I like that you call for quick cooking oats instead of rolled oats. It makes the oats less noticeable. Sometimes oats get overwhelming in a crumble top. This was perfect. Next time I will double the crumble top—my kids loved it that much! Thanks for the great recipe!

    8. I made this last night. What a hit!! I’m the only one who eats GF and everyone had seconds!!
      Served warm with vanilla ice cream. Amazing!!

    9. 5 stars
      Fast, delicious, healthy…. I substituted organic vanilla yogurt for the butter and my family devoured it before it cooled.

    10. Can I use canned blueberries for this? Or maybe a combination of canned and fresh to get the amount needed?

    11. 5 stars
      I followed this recipe using blackberries and peaches. It was delicious! The only change that I made to the crumble was that I added a bit more oats – personal preference. Delicious flavors of summer!

    12. 5 stars
      We get “Doughnut Peaches” around the area of Pa. that I live in and I’ve been combining those with freshly picked blueberries to make both the crisps and crumbles. both are fantastic!! I’ve used several recipes but yours is the first gluten-free recipe I’ve found. I’m planning on making some tomorrow for some friends. thank you!

    13. Before I make this I have a question about the amount of butter. I love recipes that ask me to use melted butter to make the crumble or crisp topping I find it’s just so much easier to work with and I still get that topping that we all enjoy. If I wanted to use melted butter in this blueberry crumble recipe how much would you suggest I use? Thank you.

    14. I’m sorry if I missed it but I don’t see the calories anywhere. How many calories are in one piece?

      1. Great question! We store it in the refrigerator with some wax paper and foil covering it. For serving to guests, it is always best day of or next day, but for enjoying on our own, we keep it in the refrigerator for about 5 days.

      I had a boatload of fresh blackberries bestowed on me just before Thanksgiving. Besides freezing some, a blackberry crumble came to mind. I followed the blueberry crumble recipe and for the most part, it was delicious. However, blackberries seem to release more juice than blueberries leaving a puddle of juice at the bottom. Perhaps more cornstarch next time, Karen? Once it cooled I drained the liquid and it was fine. Super easy, and a big hit!

      1. Yessss! I’ll be honest, whenever you bake with berries, it is always a little bit of a guess as to how much liquid they will release — frozen berries tend to release more water than fresh which is why always recommend thawing them; but I would have thought fresh blackberries would be similar to fresh blueberries so I would have followed the same recipe. Sounds like you got some really fresh, yummy ones!

    16. This is amazing! I am trying to have desserts that have little sugar and also gluten-free, yet taste satisfying…this hit all 3 of those 🙂 I also had it with a little coconut milk vanilla ice cream. YUM! Thanks for the great recipe.
