Simple Blueberry Sauce

Make the most of summer blueberries with this Simple Blueberry Sauce. Made with fresh blueberries, sugar, lemon and cornstarch. It’s great over ice cream or cheesecake!

One of the best ways to concentrate the flavor of fresh summer berries is to turn them into a sauce and blueberry lovers, this one is for you! This Simple Blueberry Sauce packs a ton of fresh blueberry flavor. I love to make this at the end of blueberry season so I can savor the taste of the sweet summer berries just a little bit longer. 

And the best news? This sauce is super easy to make. In addition to the blueberries, you’ll only need a handful of ingredients to get this on the table. Let’s talk about what you’ll need to make it. 

Blueberry Sauce Ingredients: 

BLUEBERRIES: I have only ever made this sauce with fresh blueberries so that is what I recommend using. 

SUGAR: Blueberries can be a bit tart and the sugar helps balance that out. 

SALT: Just a pinch of salt to bring out the flavor.

WATER

LEMON JUICE AND LEMON ZEST: Lemon and blueberries go hand in hand and this sauce is no different. The lemon brightens the sauce a bit. 

CORN STARCH: As the berries cook with the sugar they are going to pop and release their juices. The corn starch is going to help thicken it up and give the sauce a glossy sheen. 

How to make Blueberry Sauce: 

Blueberry sauce is a cinch to make! Essentially all you need to do is put all of the ingredients into a small pot and cook it down until thickened. It’s that easy!

STEP #1: Combine blueberries, sugar, water, lemon juice, together in a small saucepan. Cook over low heat until the berries start to release their juices. 

STEP #2: Whisk together corn starch and 1 tablespoon of water. Slowly whisk into blueberries. 

STEP #3: Reduce heat to low and continue to cook until the blueberries start to break down and the mixture thickens. It should coat the back of a spoon. 

STEP #4: Stir in the lemon zest. 

STEP #5: Serve cool or warm. 

This blueberry sauce is the perfect combination of sweet and tart and is great over pancakes, waffles, ice cream and cheesecake! 

Storage and Leftovers: 

Blueberry sauce will keep for several days covered in the refrigerator. Please note that this is not  a canning recipe and not developed with canning in mind so it may not be safe to can.
