Blueberry Crisp is the perfect dessert to serve all year round! This easy recipe features juicy blueberries topped with a sweet oatmeal crumble. We like to serve it warm with a large scoop of vanilla ice cream, this way the ice cream melts amongst the juicy berries. It’s divine!
Why you’ll love this recipe
There are several reasons why this recipe trumps others. One of my favorite aspects to this blueberry crisp recipe is the blueberry to crumble ratio is a 1:1 ratio! It makes me giddy just thinking about it. What this means is you get the same amount of crumble as blueberries in each bite. Let’s be honest, the crumble is the best part, right?! (Or am I an outlier in thinking this?)
You can use fresh or frozen blueberries to make this crisp, or a combination of both.
This dessert recipe bakes up perfectly every time!
Ingredients
For the blueberry filling you need:
- Blueberries – fresh or frozen (if using frozen blueberries they do not need to thaw).
- Granulated sugar
- Cornstarch – helps thicken the mixture so it’s not overly runny.
- Lemon juice – a little acid balances and compliments the sweetness.
For the oat crumble:
- All purpose flour – can substitute with a gluten-free flour to make this a gluten-free blueberry crisp.
- Old fashioned rolled oats
- Brown sugar – light or dark brown sugar.
- Kosher salt
- Cinnamon
- Unsalted butter – COLD and cubed.
How to make blueberry crisp
- Make the blueberry filling. In a large bowl stir together the blueberries, sugar, cornstarch, and lemon juice.
- Transfer the mixture to a 9″x6″ baking pan (that has been sprayed with nonstick spray). Spread the blueberries into an even layer.
- Make the crumble. In a large bowl whisk the flour, rolled oats, sugar, salt, and cinnamon. Using a pastry blender, cut the butter into the flour mixture. The butter should be the size of peas.
- Sprinkle the crumble over the blueberries.
- Bake. The crisp will bake in a preheated 350°F oven for 35-40 minutes, or until the crumble is golden brown and the blueberry juices are bubbling. Remove from the oven and let sit for 5-10 minutes before serving.
- Serve warm with a scoop of homemade vanilla ice cream.
FAQ and Tips
What can I do if I don’t have a pastry blender? You can use forks to cut the butter into the flour mixture or use your hands. Personally, I think using my hands is easier than forks. Just rub the butter and flour mixture between your fingers until the butter is the size of peas.
To store: cover with plastic wrap and place in the refrigerator. The crisp will keep for 5 days in the fridge.
If using fresh blueberries, remember to thoroughly wash them prior to using them in the recipe.

Hi Whitney! I have a large bag of frozen wild blueberries that I’ve been dying to do a crisp with. Do I need to make any adjustments to thicken frozen ones? I don’t want it to end up soupy. Also, can I use sea salt instead of kosher salt? I really try to watch my sodium levels because of high blood pressure. I want to make this for our Labor Day cookout. Can’t wait to hear from you. Thanks!
Hi Diana! You should be fine to make the blueberry crisp with frozen blueberries, no need to make any adjustments. And yes! You can use sea salt instead of kosher salt! Hope you enjoy the recipe! It’s one of my favorites.
