Ingredients

Scale
  • 4 cups fresh or frozen blueberries
  • 1/2 cup granulated sugar
  • 1 teaspoon lemon zest
  • 1 tablespoon lemon juice
  • 2 tablespoons cornstarch
  • Pinch of salt
  • 1/2 teaspoon ground cinnamon (optional)
  • 3/4 cup all-purpose flour
  • 1/2 cup old-fashioned rolled oats
  • 1/2 cup brown sugar
  • 6 tablespoons unsalted butter, cold and diced
  • Pinch of salt
  • 1/3 cup chopped pecans or walnuts (optional)
  • 1 store-bought or homemade 9-inch pie crust

Instructions

  1. Preheat oven to 375°F (190°C). Place a rack in the center. If using store-bought crust, thaw for 15 minutes or as directed.
  2. In a large mixing bowl, combine blueberries, granulated sugar, lemon zest, lemon juice, cornstarch, salt, and optional cinnamon. Stir gently until berries are evenly coated.
  3. In another bowl, combine flour, oats, brown sugar, and a pinch of salt. Add cold, diced butter and blend with a pastry cutter, fork, or fingers until pea-sized crumbs form. Stir in nuts if using.
  4. Place pie crust in a 9-inch pan. Pour in blueberry filling and spread evenly. Sprinkle streusel topping over the berries, covering completely.
  5. Set pie on a baking sheet. Bake for 45-55 minutes, until topping is golden and filling is bubbling. Check at 30 minutes; tent with foil if streusel browns too quickly.
  6. Let pie cool for at least 2 hours before slicing to allow filling to set.
  7. Slice and serve with whipped cream or vanilla ice cream if desired.

Notes

For gluten-free, use almond flour and certified gluten-free oats. For dairy-free, substitute vegan butter. If using frozen berries, add an extra 1/2 tablespoon cornstarch and do not thaw. Let pie cool fully before slicing for best texture. Streusel can be made ahead and chilled for extra crispiness.
