Sweet and syrupy, this is a basic recipe you will love because it's easy, takes 15 minutes to make, keeps well and can be added to cheesecakes, yogurt, ice cream, waffles.

*This is a very adaptable recipe that you can easily make sweeter or thicker.


Units Scale

For regular sauce:

  • 2 cups blueberries (fresh or frozen)
  • 2-4 tablespoons lemon juice
  • 3-5 tablespoons sugar

For a thicker sauce:

  • 1-2 teaspoons cornstarch OR
  • 1-2 tablespoon good blueberry jam


For regular sauce:

  1. In a medium saucepan put blueberries with lemon juice and sugar.
  2. Mix and cook over medium heat.
  3. Frozen berries: they already have extra water from the freezer so I don’t recommend adding any from the beginning.
  4. Fresh berries: I like to add a tablespoon of water from the start. But you can see how it goes and add some later.
  5. Cook, mixing every now and then to avoid blueberries from sticking but try not to smash them.
  6. In about 5 minutes, depending on your stove, the juice and sugar will start to become syrupy.
  7. At this point, you can taste and add more sugar or liquid.
  8. You can let the sauce thicken a few more minutes.
  9. Take into account that it will thicken as it cools.

For a thicker sauce:

  1. If you know you want a thick, gelatin-like sauce, add 1-2 teaspoons cornstarch, dissolved in a tablespoon of water, from the beginning.
  2. When it boils you will have a feeling of how much the sauce is thickening.
  3. Let it boil a minute or two if it’s too watery.
  4. Take into account that it will thicken as it cools.
  5. Alternatively, you can add some store-bought blueberry sauce to it when you remove it from the stove.



Customize - take into account that you can add more or less sugar, more or less citrus juice and adapt the sauce to your liking. Or even add a ground spice like cinnamon when you remove from heat.

Storing - this sauce keeps well for a week, well covered, in the fridge. Or up to a month frozen. If you want to keep it long term proceed as you would when making jam. Here is a good post on options for how to sterilize glass jars.

Other berries - use any other berry and change citrus juice if you want to. Blackberries with orange, strawberries with lime or orange, raspberries with lemon.
