Last year I shared my homemade strawberry sauce recipe with you and this year I wanted to share another delicious topping — this homemade blueberry sauce!

One of the great things about this blueberry sauce is that you can use fresh or frozen berries, so you can easily make it year-round. It will also keep in the refrigerator for several days or freeze well for a few months, so you can even prep it ahead of time and it’s ready to use when you need it.

I’m also sharing several different ways that you can use this sauce. And on Thursday, I’ll be sharing my favorite classic cheesecake recipe that’s another wonderful way to use it too!

What You’ll Need For This Recipe

This homemade blueberry topping requires few ingredients, but packs in tons of blueberry flavor. Here’s what you’ll need to make the sauce: 

  • Blueberries: If using fresh blueberries, look for ones that are firm and smooth with few blemishes.
  • Granulated sugar: Sweetens the sauce without making it too sweet. 
  • Water: You need just 1/4 cup of water to thin out the sauce. 
  • Lemon juice: Freshly squeezed lemon juice is best. 
  • Cornstarch: Thickens the sauce. Be sure to mix it with a little cold water before adding it to the saucepan to prevent clumping.

How To Make Blueberry Sauce

To make this blueberry sauce, start by combining some fresh or frozen blueberries, sugar, water, and lemon juice in a saucepan. You’ll stir everything together until well combined and then place it over medium heat.

After about 7-10 minutes, the blueberries will start to soften and release their juices. If you’re using frozen blueberries, this may take an additional minute or two. Once this happens, you’ll stir some cornstarch and water together to create a cornstarch slurry, which will help thicken the sauce.

Then just whisk the cornstarch slurry into the saucepan and let the mixture cook for another 3-4 minutes or until it’s thickened. 

Once it’s thickened, remove it from the heat and pour it into a heat-safe container. The sauce will be thinner while it’s warm, but it will thicken up as it cools and once it’s been refrigerated.
