Homemade blueberry pie filling in a glass jar with silver spoon.

Blueberry pie filling


This luscious blueberry pie filling is a baker’s dream. It’s rich and tasty with the perfect texture. It’s the ideal filling for pies and pastries. Enjoy it as a topping for pound cake, tarts, cheesecake.


Units Scale
  • 2 cups blueberries (fresh or frozen)
  • 1/3 cup granulated sugar
  • 1 1/2 tablespoons cornstarch
  • 1 lemon, zested and juiced
  • 1 teaspoon pure vanilla extract
  • Optional: 1/2 tablespoon butter


  1. Add blueberries, sugar, cornstarch, lemon juice, and lemon zest to a small saucepan over medium heat.
  2. Stir to coat the blueberries in sugar, and gently mash the blueberries with a spoon. But don’t mash too much. We still want some big blueberries in the mixture. We just want to release a bit of liquid so the filling doesn’t scorch on the bottom of the pan.
  3. Continue cooking the mixture, stirring often, for about 8 to 10 minutes or until it’s beautifully thick and the sugar has fully dissolved. Remove pan from heat. Add vanilla extract (and butter, if desired). Stir to combine. 
  4. After the blueberry pie filling has shed some heat, transfer it to a jar and let it come to room temperature. Cover the surface with plastic wrap so it doesn’t develop a skin. If not using immediately, attach a lid to the jar and refrigerate for up to 5 days.


IF USING FROZEN BLUEBERRIES: Defrost berries in a cold-water bath (transfer to a wide bowl and cover with cold water). Or microwave frozen blueberries on the defrost setting for 30 seconds. Drain well before using.

HOW TO THICKEN THE FILLING: If the blueberries used are extra juicy, the mixture may need more thickening. Cook the filling a bit longer to allow more of the juices to evaporate. Or make a cornstarch slurry (whisk together 1 tablespoon cornstarch plus 2 tablespoons water). Gradually stir in small amounts of slurry until the filling reaches the desired thickness.
