What Blueberries are Best for Blueberry Sauce

When buying fresh blueberries, choose berries that are plump and smooth-skinned. The color of the berries is an indicator of ripeness (not the size of the berries), so choose berries that are deep purple-blue. You can use fresh or frozen blueberries with this recipe. Frozen blueberries are great because they’re frozen at the peak of ripeness and they hold their shape better while cooking.

What You Need

You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.

Here are the ingredients you’ll need for this recipe:

  • Cornstarch — This my thickener of choice. Substitute arrowroot powder or tapioca starch.
  • Granulated sugar — for a healthy blueberry sauce, use either a zero-calorie sweetener (such as monkfruit) or use coconut sugar.
  • Water — adding just a bit of water creates a nice consistency.
  • Blueberries — Fresh or frozen blueberries work great.
  • Lemon juice — lemon and blueberries are a nice flavor combination and we’re adding just a bit of lemon juice (fresh or bottled) to enhance the sauce’s flavor.

How to Make Blueberry Sauce

Let’s talk about making this blueberry reduction.

Here are two ways to make this tasty syrup:

  1. Stovetop: Stir together the cornstarch, sugar, and water in a small saucepan. Then, add the blueberries. Turn the heat up to medium to bring it to a boil. Reduce heat to medium-low and simmer for a minute or two until the sauce thickens. Then remove the pan from the heat and add the lemon juice.
  2. Microwave: Use a sturdy pyrex measuring cup or a tall microwave-safe bowl. Stir together the ingredients as directed above. Microwave for one minute. Then stir. And repeat this in 30-second increments, until the sauce thickens.

Marly’s Tips

You can add different seasonings, such as a ½ teaspoon of vanilla, lemon zest, a few sprigs of dried thyme, rosemary, or even basil. There are lots of great flavor profiles that compliment blueberries.

Storage Tips

Once the sauce cools, pour it into a sealable container, like a mason jar and store it in the fridge. This sauce will keep in the fridge for up to 10 days.

Frequently-Asked Questions

How do you thicken a berry sauce?

Cornstarch is a great thickener for a berry sauce because it creates a perfect consistency. If your sauce is too thick, add a little more water or if it’s too thin, you can add cornstarch combined with water and bring the sauce to a boil.

How can I thicken sauce without cornstarch?

Cornstarch is a favorite thickener, but there are options you can use besides cornstarch. For example, agar agar flakes make a great zero carb thickener. You can also use arrowroot powder and even tapioca starch as a thickener.

    Thanks for the recipe! My 11 year old daughter made enough to fill 5 mason jars as gifts. Last year she made one but it took her much longer and this is just as delicious if not better. Many uses for this.

      can this be canned in a water bath process and kept room temp till ready to use ? thank you !

    • Avatar thumbnail image for MarlyMarly

      Hi Donna. That should work as long as everything is sterilized, which is sounds like you’re planning on. I have not personally canned this recipe, but it’s not much different than a jam.
