If you’re craving a simple dessert that celebrates the fresh taste of summer, this amazing blueberry crisp is the answer. With just a handful of pantry staples and fresh or frozen blueberries, you can create a warm, juicy, sweet treat that’s ready in under an hour.
Blueberry crisp is one of those desserts that feels rustic and homey, yet impressive enough to serve to guests. The filling is made with plump, sweet blueberries tossed with a bit of sugar, lemon juice, and a touch of cornstarch to thicken the juices as they bake. As the blueberries bubble and burst in the oven, they create a jammy base that’s perfectly balanced with the tart lemon and natural sweetness of the fruit.
But the real star here is the crisp topping. Made with oats, flour, brown sugar, cinnamon, and butter, it bakes into a golden, crunchy layer that contrasts beautifully with the soft fruit underneath. The topping gets irresistibly crispy around the edges while staying slightly chewy in the center, exactly what you want in a good fruit crisp.
You can serve it warm straight from the oven with a scoop of vanilla ice cream or a dollop of whipped cream for the ultimate comfort dessert. It’s just as good at room temperature, and leftovers (if there are any) make a great breakfast with a spoonful of yogurt.
This blueberry crisp is endlessly versatile too. Add a handful of chopped nuts to the topping for crunch, or mix in other berries like raspberries or blackberries for variety. And while fresh blueberries are fantastic during peak season, frozen ones work just as well, no need to thaw them first.
Whether you’re making it for a backyard BBQ, a family dinner, or a solo treat on a weeknight, this blueberry crisp is easy, delicious, and guaranteed to disappear fast. It’s the kind of dessert that never goes out of style.

Not how I expected it to taste. Maybe I’ll stick to my old recipe.
I’m sorry to hear that! Everyone’s taste is different, but maybe try adjusting the sugar next time? It could make a big difference!
Having blueberries is nice but this is just sugar and butter, no nutition!
I think you forgot to mention the baking time 🤔. I overcooked mine.
Bery good! But I didn’t have cinnamon. Still tasty!
Glad to hear it was still tasty! Cinnamon does add a nice touch, but blueberries are super delicious on their own too.
No way! How can you make blueberry crisp without cinnamon? That’s like pizza without cheese!
I was skeptical at first, but it turned out pretty good! Just a little too sweet for my taste.
OMG, this blueberry crisp is soooooo yummm!
This recipe is the best! My family loved it! Will make again!
I tried this with frozen blueberries and it turned out mushy. Not impressed.
Maybe using fresh blueberries would help? Frozen can change the texture. 🤔
This is the best recipe ever! My kids loved it!
Blueberries are my fave fruit! Gonna make dis tonight for my fam!
This recipe is sooo easy and delicious! My kids loved it, we will definitely make it again!
LOL I messed up and added salt instead of sugar! It was disgusting but i think the recipe is good otherwise.
This blueberry crisp is just divine! Made it for a family gathering and everyone loved it. Will def make it again!
That sounds amazing! I can’t wait to try it at my next family potluck. Thank you for sharing your experience!
Yum! A perfect dessert for summer gatherings. I used honey instead of sugar and it was a hit!
Sounds delicious! I love that you used honey instead.
This recipe made me feel like a baker. Lol, my house smelled so good! 😍
That’s awesome! I love when the house smells like fresh baking. Blueberries are the best! 🍇
Lol, I tried this too and mine came out super soggy. What did I do wrong? 😂
Too much sugar! I don’t recommend this if you’re watching your sugar intake. Just saying.
So easy and delicious! I used frozen blueberries because that’s what I had and it still came out amazing!
But like, frozen blueberries? Aren’t they all mushy? I dunno. I’m skeptical about that.
I love the use of frozen blueberries! They work great for recipes like this. Glad it turned out well for you!
Why not use some strawberries too? Blueberries ain’t the only berries out there! Just sayin!
You’re totally right! Strawberries would add a nice twist to the crisp. I might try that next time. Thanks for the suggestion!
Not bad, but I had trouble getting it to bake evenly. The bottom was kinda soggy. Any tips?
Is it really 4 cups of blueberries? Seems like a lot! But I guess it’s a crisp…
Wow, I made this for a party and everyone raved about it! Thank you for sharing!
Super easy! I made it using frozen blueberries and it was still great. Thx!
Just okay. I thought it would be more flavorful, it was kinda plain. I expected more from ‘amazing’…😐
Yummy!
Easy and yummy, but I added some nuts for extra crunch. 🍏🥜
I followed the recipe to the letter but it turned out a bit too sweet for my tastes. Next time I’ll cut down the sugar.
I don’t know… the blueberries were too mushy and the topping didn’t turn out right.
I’ve made this before and it turned out perfect! Maybe the berries were overripe? Just a thought!
The topping usually is all about the butter! Did you melt it too much or something?
