How to Make Homemade Blueberry Sauce

  1. Combine blueberries, water, sugar, lemon juice and salt in a saucepan over medium heat. Bring to a simmer.
  2. Add the cornstarch paste. Stir until combined. Continue cooking until thickened, about 5 minutes. Remove pan from heat and stir in the vanilla.

Expert Tips

Use fresh ingredients. It’s best to use fresh, in-season produce in order to get the most flavor. If you can buy local at the farmer’s market–even better!

Keep the heat low. If the sauce begins to bubble, it will cook too quickly and possibly burn. Be patient and allow the mixture to thicken at barely a simmer.

Taste as you go. Adjust the sweetness or acidity to your liking. If you want more lemon flavor, add more juice or zest. For less sweetness, start with 1/3 cup sugar and add more as needed.

Storage Tips

Store in an airtight container in the refrigerator for up to 2 weeks. Make sure the sauce is completely cooled before storing. It can also be frozen for up to 3 months. Defrost in the refrigerator overnight.

Jar the sauce and store at room temperature for up to 6 months. To properly jar, fully submerge the mason jar and lid in boiling water. Boil for 10 minutes, then use tongs to remove them from the water. Use a funnel to transfer sauce to the jar. Wipe the rim clean and secure the lid on top. Return the jar to boiling water for 10 more minutes (make sure it’s fully submerged). Let the jar cool completely overnight, then check that the jar is properly sealed by making sure that the lid does not pop up and down.

Recipe FAQ

How do I reheat blueberry sauce?

Cook sauce over a low heat on the stovetop, stirring occasionally, until warm. ALternatively, reheat the sauce in the microwave, stopping to stir every 10 seconds.

Why is my blueberry sauce runny?

Most likely it wasn’t cooked long enough. Keep the sauce simmering on the stove until it’s thick enough to coat the back of the spoon. You can also sprinkle in a little extra cornstarch.

Can I add other fruits to the sauce?

Absolutely! Aim for 2 cups fresh berries in this recipe.

Can I use frozen blueberries?

Yes. Do not defrost them and use only 1/3 cup water in the recipe. You can add more water if the consistency is too thick, but it’s unlikely since frozen berries will release water as they cook.
