This blueberry crumble has layers of plump and juicy blueberries covered with a crumbly topping and piled high with vanilla ice cream (sigh…). Can you tell I’m looking at the picture, typing this?
This is my favorite blueberry crumble because: (1) it tastes incredible (2) it’s not overly sweet; a perfect balance of sweet and sour (3) this blueberry crumble is easy to prepare! You don’t have to blanch the fruit, or peel the skin, pit, or slice as with my peach and apricot crumble (although when those stone fruits come in season, you have to try that one too; trust me!).
This crumble is done in 5 easy steps. You’ll impress your family and friends and they’ll think you spent loads of time on it; your secret is safe with me ;).
Did you know cinnamon really intensifies the flavor of blueberries? Also, lemon juice and lemon zest go really well with blueberries. I knew both so I figured they could jam together. I was on to something! This blueberry crumble will knock your socks off and you’ll be running back for more.
Ingredients for the Blueberry Crumble Filling:
2 to 2 1/4 pounds (about 36 oz) fresh blueberries, rinsed and well-drained
2 Tbsp lemon juice, freshly squeezed
1 tsp lemon zest (zest of 1 lemon)
3 Tbsp all-purpose flour
1/4 cup granulated sugar
1 tsp ground cinnamon
Ingredients for the Blueberry Crumble Topping:
1 cup all-purpose flour *measured correctly
1/4 cup granulated sugar
1/3 cup brown sugar, packed
1/8 tsp (generous pinch) of salt
8 Tbsp (1 stick) cold, unsalted butter, diced
½ cup quick-cooking oats
1 cup sliced almonds, divided
To Serve:
Vanilla ice cream or whipped cream, optional
How to Make the Best Blueberry Crumble:
1. Toss blueberries with 2 Tbsp lemon juice and 1 tsp lemon zest and set aside.
2. In a small bowl, whisk together 1/4 cup sugar, 3 Tbsp flour and 1 tsp ground cinnamon and toss with the blueberries just until evenly coated. Pour into a 9 x 13– inch baking dish.
3. In a food processor fitted with a steel blade, combine 1 cup flour, 1/4 cup granulated sugar, 1/3 cup brown sugar, and 1/8 tsp of salt. Pulse several times to combine. Add the diced cold butter and pulse until the butter is the size of peas.
4. Transfer the mixture to a bowl, add 1/2 cup oatmeal and use your hands to make large crumbles. Add ½ cup of the sliced almonds and mix to combine.
5. Spread the topping over the fruit and cover evenly, then sprinkle ½ cup of almonds over the top. Bake 40 minutes at 350˚F. The blueberries should be bubbling at the edges and the topping and almonds should be golden brown.
Here’s the hard part: let the crumble sit for at least 15 minutes before serving (it will thicken slightly as it cools). This will stay warm for a couple hours. It reheats beautifully the next day.

NOW ABOUT THAT GIVEAWAY (Giveaway Ended):
Why a giveaway? It’s a reader appreciation giveaway. I want you to know that I appreciate every one of you who visit my blog, take the time to comment, and share it with your friends and fam. You all inspire me to be a better cook and blogger. Thanks to all of you who follow my profiles on Facebook, Instagram and Twitter and for thinking I’m worth following even when I post weird things like garage sale hauls. I’m crazy about ya! And I wish I had a LeCreuset prize for each of you.
Le Creuset sponsored this giveaway. I asked them to and they said yes; how nice is that?!
You can find Le Creuset on Facebook, Instagram, Twitter and Pinterest!
Everything about Le Creuset is timeless, classic, incredible quality and beautiful. This is my first le creuset casserole dish and it’s amazing how you can tell the difference between this casserole and the one I bought at Ikea! I can see myself passing this down to the next generation. The quality is exceptional. I like holding it and when I carry it back to my buffet for storage, it feels so good in my arms. Ok, I’m totally in love with this thing! I wish I had one for each of you. It’s a 4 Qt Le Creuset covered stoneware casserole (in the color of your choice from the matte collection – subject to availability) and that lid is so convenient. No more foil over my casseroles and transporting them will be a breeze! P.S. The color of this is: Matte Collection – Cotton. It measures 11 1/2″ x 7 3/4″
The medium spatula from Le Creuset is also part of this giveaway. Here’s why I love it: (1) It’s pretty (2) It feels really good in your hand (3) it’s highly lick-able – no kidding!
Disclosure of Material Connection: I received the product(s) mentioned in some of the posts on my blog in the hope that I would give it a good review on my blog. Regardless, I ONLY recommend products or services I use personally and believe my readers will enjoy.
Super excited to try the recipe. Tripled it, took the advice of another, adding extra butter to topping. Unfortunately, the photo doesn’t match the outcome—very dry and powdery topping. Consider reviewing and revising.
Hi, a powdery topping is usually due to not mixing the butter into the flour enough or not using enough butter. Did you use the full 8 Tbsp or 113 grams of butter?
Hi Natasha! How can I re-heat this? I made this blueberry crumble and it was a hit!
Yes, it reheats beautifully the next day.
This was really, really good! I actually used a can of blueberry pie filling – in case anyone doesn’t have fresh or frozen, know that it works well! I added three extra tablespoons of butter as my topping was more “sandy” than “clumpy.” Best topping ever! Thank you for this recipe~it’s a keeper!
Great idea with the filling. Thank you so much for sharing that with me, Debbie. I’m so glad it was a hit!
I made this twice now, easy and delicious. I did change a few items, substituted almond flour and used agave instead of white sugar. I didn’t think there was enough toppings so I doubled it.
Hi Julie! Thanks so much for sharing your substitutions with us. That’s great to know. I’m glad you liked the recipe.
Can I use frozen blueberries instead of the fresh ones for the crumble recipe? The fresh ones can sometimes be quite tart; the frozen ones I buy are guaranteed sweet.
Hi Rory! Here is what one of my viewers said: “I used 30 oz frozen blueberries but followed the rest of the instructions. The crumble was so perfect… exactly the way I like it!”
Loved it, i made it in a smaller pan so the blueberry layer was thicker and it worked well
So glad to hear that!
Hi Natasha, I am planning on making this but can I use a blender instead of a food processor?
Hi Cathy, I haven’t tested that to advise. If you give that a try, we’d love to know how it turns out!
Can use hands to make crumble if you don’t have a food processor just as easily, i recommend letting the butter SOFTEN, not melt! The blueberry layer was a bit thin so i will be using a different pan next time
Thank you so much for sharing that with me, a pastry cutter will work also.
THIS RECIPE IS DELICIOUS!! I used 1/2 blackberries and 1/2 blueberries. It did take about 1.5 hours to fully cook through and crisp up.
Thank you for sharing, Ashton!
The whole family is obsessed with this, including myself. Blueberries are so good right now this time of year so I’m making a ton of it! This is by far the best crumble topping I’ve come across. Works for apples as well!
I’m so lucky to have found your site, thank you! 💕🔥
Hi Heather! Thank you so much. I’m glad you love this recipe.
Natasha, this was a hot out of the ball park, per usual!! So amazing now that the fresh blueberries are coming into season!
I’m wondering if I can use any other rolled or old fashioned oats in place of the quick?
He Heather! I think that would work fine too. I would not recommend steel-cut oats. You’ll want something that will cook faster. That is why I recommend quick-cooking oats.
If I could give this another star I would. I have made this recipe exactly as listed at least half a dozen times, always turns out perfect and always appreciated by family and friends. Yesterday I made it with rhubarb and strawberries, equally appreciated. Thank you
That sounds amazing, Eldora! Thank you so much for the review. I’m glad you love the recipe.
Wow, your so fun to watch while cooking wonderful recipes. Just made lemon bars for Thanksgiving and was simple enough for me to follow. Look forward to making many of your recipes. Happy Thanksgiving
Thank you for that wonderful compliment, Sarah! Happy Thanksgiving!
This is a yummy easy recipe. I wasn’t fond of the oatmeal. Would prefer a topping without it. The filling, I filled up on. If you like oatmeal this is the rd pie for you.
Thanks for sharing that with us, Cheryl. 🙂
I have never made one of your recipes that didn’t work out great! Seriously! I’m making the crumble now. Can’t wait till it’s done. I cut the recipe in half to not have leftovers.
Thank you, Sandy! I hope you love this recipe as well! 🙂
