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!

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!

I was looking for a blueberry crumble recipe and came here because of the many good reviews. Now I’m adding my own raves. My husband said “This is the best dessert I’ve had in a long time.” I knew lemon and cinnamon went well with blueberries separately, but never tried them together. It’s a triumph. I put chopped almonds in the crumble, and topped with walnuts. Thanks for this recipe. It’s perfect.
You’re welcome Jill! I’m glad you both love the recipe. Thanks for sharing your excellent review with other readers!
This is so awesome. I’m a big fan of blueberries. THIS has extra. I made it and it’s SO GOOD! I could make it and eat it again and again.
I’m glad you love the recipe just as much as I do Olga! Thanks for sharing your wonderful review!
Absolutely AMAZING!!!
Highly recommend!
Awesome, I’m glad to hear that Alana! Thanks for sharing!
I would like to try this to bring to a Thanksgiving dinner where one person has a severe dairy allergy. Can you recommend a butter substitute that would be good in this recipe??
Hi Laura, that is very thoughtful of you to consider the person with allergies! I haven’t tried anything other than butter but I wonder if chilled coconut oil would work well in the crumble topping. You might google coconut crumble to see if anyone has already tried it. If you test it out, let me know how it goes! 🙂
Thank you so much for this amazing recipe!! Love the hint of lemon and cinnamon, really makes the flavour of the blueberries pop. It’s a Sunday dinner family favourite…I have to make 2 recipes for our extended family dinner just so I can have some for leftovers!!
You’re welcome Linda! I’m glad to hear how much you and your family enjoy the recipe! Thanks for sharing your excellent review!
I’m fixin to make this tomorrow! Looks yummy 😆
It’s delicious! Please let me know what you think Cindy!
This recipe is amazing!!! I really want to make it again. The extra blueberries are the best. Thank you natasha!!
You’re welcome Olga! I’m so glad you love it! Thanks for sharing your great review!
Hi, would blackberries work for this recipe?? Thanks
Hi Victoria, I haven’t tried that but it sure sounds delicious if you have alot of blackberries! 🙂
Sure would. I have also tried this with homegrown peaches. Delish!
Mmm that sounds amazing! 🙂
I made the Blueberries crumble and is the BEST I have ever had. I have been heasitant to make blueberries pies or crumbles because I had both in different occasions and tested like medicine or too sweet, but once I read the description, I had a great feeling. My son loved it also and told me not to put his plate away:). Thank you for sharing your amazing recipes.
You’re welcome Wendy! What a fantastic review! I’m happy to hear how much you and your family enjoy this recipe! Thanks for sharing 🙂
Would substituting the almonds with another nut work just as well? Say, pecans or walnuts?
Hi Marina, I think that would work fine to add chopped pecans or walnuts 🙂
It was delicious! I halfed the ingredients bc i didn’t have enough blueberries. I used frozen blueberries and raspberries btw. My husband and daughter devoured it! “SO good!” is what they said. Thank you and now I really want to get the covered casserole now!
That is so sweet! Thank you for sharing your wonderful review! 🙂
Hi Natasha,
I just found your website this month and decided to give the blueberry crumble a try. I loved the simplicity and it came out as promised! I wanted to mention that I found I needed more oats for a 9 x 13 pan, so I increased from a half cup to 1 cup. I also decided to lightly broil the topping after 40 minutes of cooking, to give it a more golden color. It was delicious and I’m excited to try more of your recipes. Thank you!
Lisa, welcome to the site and thank you for the wonderful review. I like the idea of broiling, just don’t forget to take it out in time 😀.
How many Cups equal 2 lbs?
Audrey, 2 lbs of blueberries will yield around 6 cups. Hope this helps 😁.
Thank you
i really loved this recipe all of the kids loved it i will keep a look out for more ingredients we also included marble ice cream and coconut whipped cream
Wow that sound seriously amazing!
I just made the blueberry crumble for a get together tomorrow at my house and I made it with 3lbs of blueberries and it is in the oven…..tomorrow I shall reheat and watch everybody enjoy!
Oh my goodness that sounds amazing right now!!
Made this recipe the other day with frozen blueberries. I added extra spices, because we like it better that way. The topping was great, so was the blueberry layer! None of us could decide which of the two we liked best! Thanks for sharing! I will be making this again!
That’s awesome! I’m so happy you liked the recipe! 🙂
Would it be possible to use frozen blueberries? I would like to make this for Christmas.
I think it would work but thaw them in the fridge and use 1 Tbsp more flour and 1 Tbsp less lemon juice since frozen berries can be a bit juicier. Merry Christmas!
Hi! Do you think it would be ok to just use a mixer to combine the ingredients instead of food processor? ill still be able to leave pices of butter intact, thanks !!!!
Dani, if you don’t have a food processor, just work the butter in to the mixture, using your hands, until you get the same crumbles.
thanks so much!! And sorry one more, im using frozen blueberries, do you think that’s ok? thanks a million! your site is wonderful!!
I think it would work but thaw them in the fridge and use 1 Tbsp more flour and 1 Tbsp less lemon juice since frozen berries can be a bit juicier 🙂
A knife and fork can also do the job well if you don’t want to get your hands dirty. Both are much easier to clean than other items. My family has used this method for generations when cutting a fat into flour.
I’m going to try this recipe as I must limit my food to low-fat. I am also going to try the Creamy Tomato with Chicken recipe but not use full fat products. I’ll let you know how both go. Thanks for the ideas!!!
Thanks for sharing your tip! I hope you enjoy both recipes 🙂
Fresh blueberries picked today, used lime instead of lemon. It was fantastic with some butterscotch ice cream.
Wow that sounds like an amazing combination! Thank you for sharing 🙂
The BEST I’ve ever tasted! I used a little less sugar on the blueberries, and Red Mills’ gluten-free Baking Flour. Absolutely delicious. The almonds make it truly spectacular. Thank you!
I’m so happy you loved the recipe! 🙂
Hi! Looks delicious. Is it ok to double the topping for it?
Thank you!
Hi Michele, I haven’t tested it that way, so I can’t say for sure. This seemed like just the right amount of topping to me so I probably wouldn’t experiment with more. I’m guessing you may need to bake longer for the topping to bake properly if you double it.
