Ingredients

For the Pie

  • 1 pie crust 1 pie crust (9-inch, single crust on bottom; top crust or lattice optional)
  • 2 cups 2 cups fresh or frozen blueberries
  • 2 cups 2 cups fresh or frozen raspberries
  • 2 cups 2 cups fresh or frozen blackberries
  • 1 cup 1 cup granulated sugar For a less sweet pie, reduce to 3/4 cup
  • 3 tablespoons 3 tablespoons cornstarch Increase to 4 tablespoons if berries are particularly watery
  • 1 tablespoon 1 tablespoon lemon juice (fresh preferred)
  • 1 teaspoon 1 teaspoon vanilla extract
  • 1/4 teaspoon 1/4 teaspoon salt

Instructions

Preparation

  • Preheat your oven to 375°F (190°C).
  • In a large bowl, combine the blueberries, raspberries, and blackberries.
  • Sprinkle the sugar and cornstarch over the berries. Add the lemon juice, vanilla, and salt.
  • Toss gently to coat the berries evenly without crushing them.
  • Pour the berry mixture into the prepared pie crust, mounding slightly in the center.
  • Add a top crust or arrange a lattice. Trim excess dough and crimp the edges to seal. Cut a few vents if using a full top crust.
  • Optional: Brush the crust with beaten egg or milk and sprinkle a little sugar for shine and crunch.

Baking

  • Bake on a rimmed baking sheet for 45–50 minutes, until the filling is bubbling and the crust is golden brown.
  • Remove the pie and let it cool on a wire rack for at least 2 hours so the filling sets before slicing.

Notes

Use frozen berries straight from the freezer; do not thaw. For storing, keep covered at room temperature for up to 2 days, refrigerated for 3–4 days, or frozen for up to 2 months.
