Sweet, juicy blueberries baked beneath a golden, buttery oat topping—Blueberry Crisp is the quintessential summer dessert. It’s easy to prepare, incredibly satisfying, and perfect for backyard gatherings, holiday meals, or a cozy night in. Serve it warm with a scoop of vanilla ice cream for a classic treat that never fails to impress.
For the blueberry filling:
6 cups fresh or frozen blueberries
2 tablespoons cornstarch
1/3 cup granulated sugar
1 tablespoon lemon juice
1 teaspoon lemon zest
1 teaspoon vanilla extract
Pinch of salt
For the crisp topping:
1 cup rolled oats
3/4 cup all-purpose flour
1/2 cup brown sugar, packed
1/2 teaspoon ground cinnamon
1/4 teaspoon salt
1/2 cup unsalted butter, cold and cubed
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish or 2-quart casserole dish.
In a large bowl, combine blueberries, sugar, cornstarch, lemon juice, lemon zest, vanilla extract, and salt. Toss until evenly coated. Transfer to the prepared baking dish.
In a separate bowl, mix oats, flour, brown sugar, cinnamon, and salt. Add cold cubed butter and use a pastry cutter or fingers to combine until the mixture resembles coarse crumbs.
Sprinkle the oat topping evenly over the blueberry mixture.
Bake for 35–45 minutes, or until the topping is golden and the fruit is bubbling.
Allow to cool for at least 10–15 minutes before serving. Best served warm with vanilla ice cream or whipped cream.
If using frozen blueberries, do not thaw before baking to avoid excess moisture.
Almond flour can be used to make this recipe gluten-free.

Add 1/3 cup chopped nuts to the topping for extra crunch.
