  • 2 cups (290 grams) fresh or frozen blueberries
  • 1/3 cup (65 grams) granulated sugar
  • 1/4 cup (60 ml) water
  • 2 teaspoons fresh lemon juice
  • 1 tablespoon (8 grams) cornstarch + 2 tablespoons (30 ml) cold water


  • Add the blueberries, sugar, 1/4 cup water, and lemon juice to a medium-sized saucepan and stir until well combined. Place the saucepan over medium heat and allow to cook for 7-10 minutes or until the blueberries start to soften and release their juices.
  • In a small bowl, whisk together the cornstarch and 2 tablespoons of cold water. Add to the saucepan and stir until well combined. Allow the sauce to cook for an additional 3-4 minutes, stirring often, until the sauce has thickened.
  • Remove from the heat and carefully pour into a heat-safe container. Cool completely at room temperature, then cover tightly and store in the refrigerator until ready to use.


This recipe will yield 1 and 1/2 cups of blueberry sauce.
Store leftover blueberry sauce in an airtight container in the refrigerator for up to 5 days.
Freezing instructions: This sauce will freeze well in a freezer bag/container for up to 3 months. Thaw overnight in the refrigerator and warm in a saucepan on the stove top until the sauce is smooth.
