Ingredients
For the Blueberry Filling:
6 cups fresh or frozen blueberries
1/2 cup granulated sugar (adjust to taste based on berry sweetness)
1 tablespoon lemon juice
2 tablespoons cornstarch or all-purpose flour
For the Oat Crumble Topping:
1 cup old-fashioned rolled oats
1/2 cup all-purpose flour
1/2 cup light brown sugar, packed
1 teaspoon ground cinnamon
1/4 teaspoon salt
1/2 cup (1 stick) cold unsalted butter, cut into small cubes
Instructions
Step 1: Preheat your oven to 375°F (190°C). Lightly grease an 8x8 or 9x9 inch baking dish.
Step 2: In a large bowl, gently combine the blueberries, granulated sugar, lemon juice, and cornstarch (or flour). Toss until the blueberries are evenly coated.
Step 3: Pour the blueberry mixture into your prepared baking dish and spread it out evenly.
Step 4: In a separate medium-sized bowl, whisk together the rolled oats, all-purpose flour, light brown sugar, ground cinnamon, and salt.
Step 5: Add the cold, cubed unsalted butter to the dry ingredients. Using your fingertips, a pastry blender, or two knives, cut the butter into the mixture until coarse crumbs form. A few larger pieces are fine.
Step 6: Sprinkle the oat crumble topping evenly over the blueberry filling in the baking dish.
Step 7: Place the baking dish on a baking sheet and bake in the preheated oven for 40-50 minutes, or until the topping is golden brown and the blueberry filling is bubbling thickly around the edges.
Step 8: Once baked, carefully remove the crisp from the oven. Let it cool on a wire rack for at least 15-20 minutes before serving. This allows the filling to set.
Notes
For best results, use ripe, firm blueberries. If using frozen blueberries, do not thaw them; simply toss them with the sugar and cornstarch directly from frozen. This helps prevent a soggy bottom. Don't overmix the topping; a crumbly texture is key.
