In a small bowl toss together the blueberries with the cornstarch and the sugar until well-coated. Put blueberries into two ramekins (I used Aplico #3 which are about 10 ounces each) and set aside on a rimmed, foil-lined baking sheet.
In another small bowl combine the flour, oats, brown sugar, and salt. Cut in the butter with a pastry blender and use your hands to work it all together, working the butter into the dry ingredients until the mixture is crumbly.
Sprinkle the crumble mixture over the berries and bake for 30 minutes, or until the berries are bubbly and the topping is golden.

Josee Marchessault on 2026-02-19 (5 stars): What a clever and easy recipe for those leftover blueberries from the big Costco clamshell container. Proportions are perfect and since we are two who love fruit crisp in our family it’s the best recipe ever! I will save it to use with other fruits xo
Heather Meech on 2025-09-02 (5 stars): Perfect dessert for two. Quick and easy and can be prepared the day before and then baked the next day.
Rachel on 2025-04-28 (4 stars): I added lemon juice and a pinch of salt to the blueberries. Really glad I did! I like that it’s not overly sweet.
Debbie on 2024-08-15 (5 stars): Quick, easy, and oh so delicious!
Melissa on 2024-07-27 (5 stars): This crisp turned out perfectly and was so delicious! I cut the recipe in half and made just one but I should have made both because I'm probably going to make another one tonight. I did add a bit of nutmeg to my crisp topping because I love it with blueberries. Thank you for sharing the recipe!
Elaine on 2024-07-21 (5 stars): Thank you for this delicious recipe. Soooo good! (especially warm with ice cream)
I love how you can easily halve it to make a single serving for one person or multiply it for as many people as you like. I will be making this one often during blueberry season :)
