Ingredient Notes
To make this sweet and easy Blueberry Sauce, you will need the following ingredients (full measurements in recipe card below):
- blueberries - you can make this easy blueberry sauce with fresh or frozen blueberries.
- water
- sugar - feel free to adjust the level of sweetness that you prefer by adding in more or less sugar.
- lemon juice - lemon pairs so well with blueberries, so we added it in. You can substitute this with orange juice for another citrus flavor.

- cornstarch - helps to thicken the sauce.
You will also need measuring cups and spoons, a medium saucepan, and a small mixing bowl.
How to Make the Best Blueberry Sauce
- Cook the ingredients. In a medium saucepan, Add 1.5 cups blueberries, water, sugar, lemon juice, and vanilla extract. Cook on medium-high heat until the mixture comes to a boil. Reduce the heat to low and simmer for 5-7 minutes until the blueberries start to break apart, stirring constantly.
- Add cornstarch. In a small mixing bowl, whisk together cornstarch and water until smooth. Add the cornstarch slurry to the saucepan and stir constantly until thickened to a desired consistency, about 2-3 minutes. Note that the sauce will thicken more as it cools.
- Stir in more blueberries. Stir in the remaining 1 cup blueberries. Let the sauce cool to room temperature. Then, transfer the blueberry sauce to an airtight container and refrigerate overnight.

There are millions of ways you can use blueberry sauce. Here are some of my favorite ways to serve this sweet sauce:
- Stirred into Yogurt or Oatmeal.
- On the side of a Charcuterie Board.
- Over French Toast, Waffles, Pancakes, Scones, toast, or custard.
- Mixed into or over cheesecake such as in our Blueberry Cheesecake.
