Ingredients

Scale

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

Instructions

  • 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.

Notes

  • If using frozen blueberries, do not thaw before baking to avoid excess moisture.

  • Almond flour can be used to make this recipe gluten-free.

  • Substitute butter with coconut oil for a dairy-free or vegan version.

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