Instructions
- Step 1: Prepare the pie dough by combining 2 1/2 cups all-purpose flour with 1/2 tsp salt and 1/2 cup granulated sugar in a large bowl. Cut in 1 cup cold unsalted butter cubes using a pastry blender until the mixture resembles coarse crumbs. Add 6 tbsp ice water gradually, mixing gently until the dough just comes together. Divide the dough into two discs, wrap in plastic, and chill for 30 minutes.
- Step 2: Preheat oven to 375°F. In a large bowl, toss 5 cups fresh blueberries with 1 tbsp lemon juice, 3 tbsp cornstarch, and 1 tsp ground cinnamon until evenly coated.
- Step 3: On a floured surface, roll out one dough disc to fit a 9-inch pie plate. Transfer it to the plate and trim edges.
- Step 4: Pour the blueberry filling evenly into the crust.
- Step 5: For the crumb topping, mix 3/4 cup brown sugar, 3/4 cup rolled oats, and the remaining 1/2 cup all-purpose flour (from dough preparation) with 1/2 cup cold unsalted butter cubes cut in until crumbly.
- Step 6: Sprinkle the crumb topping evenly over the blueberries.
- Step 7: Bake for 45–50 minutes until the topping is golden brown and filling is bubbly. Let cool for at least 2 hours before serving.
