  • 2 pie crusts or our Easy Pie Crust Recipe (see notes)
  • 2 cups blackberries
  • 2 cups raspberries
  • 2 cups blueberries
  • 1 cup white granulated sugar
  • 1 Tbsp. lemon juice
  • 1 Tbsp. lemon zest
  • 4 Tbsp. cornstarch
  • 2 Tbsp. unsalted butter
  • 1 egg white


  • Preheat oven to 400F
  • Add raspberries, blackberries, blueberries, sugar, lemon juice, and lemon zest to a medium size sauce pan and cook over medium heat until warm and juicy, about 5-10 minutes, stirring occasionally.
  • Spoon out about 1/2 cup of fruit juices and place into a small mixing bowl. Add cornstarch and stir until it becomes smooth. Bring berries back to a simmer and stir in the cornstarch mixture. Gently stir until filling starts to thicken, about 2-3 minutes.
  • Remove from heat and gently stir in butter until melted. Let mixed berry pie filling cool for 15-20 minutes.
  • Lightly grease a 9 inch pie dish, and place bottom pie crust into dish. Brush bottom pie crust lightly with a beaten egg white.
  • After berry pie filing has cooled, pour mixture into unbaked pie crust.
  • Top your pie with a full pie crust or a lattice crust. For a full pie crust, brush edges of the bottom pie crust with water and lay the full crust on top of the berries. Crimp the edges and cut slits in the top of crust. *see notes for lattice crust. 
  • Brush a thin layer of a beaten egg white over top of the crust and sprinkle with granulated sugar.
  • Place mixed berry pie in a preheated 400F oven for 40-45 minutes. Check pie after 30 minutes, and if it’s getting too brown, place a piece of tinfoil over top of pie and continue baking.
  • Remove from oven and allow triple berry pie to cool for a few hours before serving. Once cooled, slice and serve with whipped cream or vanilla ice cream. Enjoy!
