We all love blueberries, so it’s no surprise that we’re taking this beloved summertime fruit and transforming it into a decadent sauce.

This stuff is addictive… and it makes enough to enjoy some now while also freezing some for later.

More on this down below. 😉

Why I love this recipe:

This from-scratch Blueberry Sauce is sweet with a little tanginess. The blueberries hold their shape as you cook them down and burst in your mouth when you take a bite.

It’s also perfectly sweet—but not too sweet—and tastes like pure blueberry goodness.

And when served over cheesecake, the tartness of the berries pairs beautifully with the creaminess of the cheesecake. It’s a glorious combination.

Whether you use this as a blueberry sauce for pancakes, a blueberry sauce for cheesecake or a blueberry sauce for ice cream… well, you’re in for a treat.

Let’s talk ingredients!

In addition to the tools above, you’re going to need some ingredients to make this recipe, too! Chances are, you might already have some of them in your fridge or pantry. Scroll down to the recipe card for the full measurements and instructions.

Here’s what you’ll need:

  • Blueberries—you may use fresh or frozen blueberries. Both should work perfectly here! Just note that frozen blueberries will take more time to melt and cook down and might not hold their shape as well.
  • Granulated sugar—also known as “white sugar,” this is the sweetener we’re using in our sauce.
  • Cornstarch—this is going to help the sauce thicken. A little goes a long way, so please don’t overmeasure! It will change the texture of the sauce if there is too much or too little corn starch, which is also known as corn flour.
  • Lemon juice—I juiced a lemon for this recipe and love the acidity the juice adds. You don’t get a ton of lemon flavor, but it’s there in the background. Lemon and blueberries play nicely together, so this works!
  • Water—we need just a splash of this to thin out the sauce and help those blueberries hold their shape.
  • Sea salt—you’ll just need a pinch of fine sea salt or kosher salt. This will serve as a counterbalance of the sweet and help give it a nice pop.
  • Vanilla extract—I love to use just a little bit of pure vanilla extract. It adds a wonderful aroma and undertones of vanilla to the sauce.

What can I serve this blueberry sauce on?

How to make Blueberry Sauce

Combine the ingredients. In a large saucepan, combine the blueberries with the sugar, cornstarch, lemon juice and water. Season with a pinch of salt. Stir to coat.

Add the liquids. Measure in the lemon juice and water.

Cook it down. Heat the blueberries over medium heat. You’ll cook them for about 5 minutes, until the sauce is bubbling and has thickened. You want the blueberries to still mostly be holding their shape.

Pro tip!

If you’re using frozen blueberries, cooking them down will take longer. Also, they are less likely to hold their shape, but that’s OK.

Add the vanilla. Once the blueberry sauce is the correct consistency, pour in the vanilla, and stir.

Cool it off. Let the sauce cool for 15-20 minutes before transferring to a mason jar.

Serve it up. You can serve this sauce warm (but not super hot, unless you want to melt your dessert) or cold. Keep it in the fridge for up to two weeks!

It pairs so nicely with so many different things.

Here’s how you can entertain with it:

Frequently Asked Questions

Can I use frozen blueberries in this recipe?

Yes. Use the same amount. However, cooking them down will take longer. They are also less likely to hold their shape, but that’s OK.

Can you use flour to thicken berry sauce?

While you could use flour to thicken this, I really like to use cornstarch because you do not need much. Also, you don’t have to cook it down to get rid of the raw flour taste.

How do you thicken a berry sauce?

We use cornstarch to thicken this recipe.

How long will blueberry compote last?

You can keep this in the fridge for around two weeks. You can also freeze it for up to 3 months.

What is difference between compote and jam?

In a jam, fruit is broken down while a compote still has whole fruit in it. Compotes have no pectin, which is oftentimes added to jam and jellies for texture, so they tend to be thinner.
