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

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 zest plus lemon juice: Freshly squeezed lemon juice is always best. 
  • Cornstarch: Thickens the sauce. Be sure to mix it with a little cold water before adding it to the saucepan to prevent clumping. 

The thing I love the most about this easy blueberry lemon sauce is the fact that it comes together on the stovetop in less than ten minutes with just a few staple ingredients.

That’s right. Fresh or frozen blueberries, water, sugar, lemon juice and cornstarch are all you need.

Baking tips

  • You can use fresh or frozen berries for this recipe. If using frozen berries, there’s no need to thaw them first.
  • The sauce will be a little thin while it’s warm, but will thicken more as it cools and after it’s been refrigerated.
  • If you freeze the sauce, I suggest thawing it overnight in the refrigerator and then warming it up in a saucepan until it’s nice and smooth.
