This is the best blueberry crisp you’ll ever make! It’s everything you want in a summer dessert: perfectly balanced, not too sweet, very berry forward, with an extra thick crisp topping. Serve warm with a generous scoop of vanilla ice cream!
As soon as summer hits, I’m baking with blueberries all season long. This blueberry crisp with oats is a seasonal favorite for me. It’s so simple to throw together, and it comes out of the oven jammy, bubbling, and perfect.
One trick I’m using from my blueberry pie recipe: adding a spoonful of blueberry preserves to the filling. It makes the fresh blueberries taste especially vibrant. Lemon zest and juice add another layer of brightness!

Overview: How to Make Blueberry Crisp
Mix together rolled oats, flour, brown sugar, cinnamon, and salt in a medium bowl.
Cut in cubed butter with a pastry blender until the mixture is well combined and forms large crumbs. Place the crisp topping in the freezer to chill until you’re ready to use it.
Whisk together sugar, arrowroot starch, and salt in a large bowl. Add blueberries, preserves, lemon zest, and juice, then gently toss everything together until well coated.
Spoon blueberry filling into prepared baking dish and sprinkle evenly with topping. Bake until topping is golden and filling is bubbling, about an hour.
Let cool for at least 1 hour so the filling has time to rest and thicken slightly. You’re going to love this easy blueberry dessert!

Gluten free crisp: Make a gluten-free version of this blueberry crisp by substituting gluten-free oats and gluten-free flour in the topping.

Delicious! I added about a 1/4 tsp of ground coriander to the filling which I learned from Stella Parks. It gives it a little floral, herby note which pairs really well with the blueberries and lemon. Excellent crumb to filling ratio. A winner with the family!
Thanks so much for your feedback, Louann! The coriander sounds amazing – I also love to pair some fresh thyme with berry desserts. 🙂
This crumble was one of the best (if not the best) I’ve ever made! I don’t typically bake with blueberries but boy was this ever delicious!
Looks perfect, Patti! 🙂 Thanks so much for sharing!
This turned out amazing! My wild blueberries were slightly tart, so I added 2 extra tablespoons of blueberry jam to the filling. So delicious!
Wild blueberries sound amazing here, thank you Lorie!
Fabulous crisp! I used local blueberries from the farmers market. Planning to make again for the 4th.
Great to hear this, thank you Brooke!
Just made this for a potluck, and everyone loved it. The only change I made was using strawberry preserves as I did not have blueberry preserves.
Thanks so much for your feedback!
