🍯 Why This Recipe Works
- It only takes a few minutes to cook. Making this chia blueberry jam only takes a few minutes, and because this jam is fridge-stable, we don't need to dive into a long water bath canning process.
- It has a nice "shelf life." Once made, this SF blueberry jam will last about 2 weeks in the fridge, so you should have plenty of time to find uses before needing to make a new batch.
- It tastes delicious. While you'd think that a sugar free jam would taste a little tart, this jam actually has a great flavor because it's not too sweet and not too tart!
Blueberries- Use fresh or frozen. If using fresh, you may need 1 tablespoon of water to be added during the initial cooking process.
Lemon juice- Adding lemon juice is what helps to extend the shelf-life of this jam. Without it, the jam would only be good for a few days, so make sure to not skip this ingredient.
Chia seeds- We don't need a lot to make this simple jam recipe, but we do need some Chia seeds. These are little seeds that, when wet, will expand in size and work as a binding agent, so instead of using pectin, we use chia seeds to give us that jam-like consistency.

🔪 Instructions for Sugar Free Blueberry Jam
Step 1: Wash fresh blueberries or use frozen blueberries and add them to a medium-sized pot over medium heat on the stove.
Step 2: Cook for about 6-8 minutes or until the blueberries are soft and mashable with the back of a spoon.
Step 3: Remove from heat and use a potato masher to crush the blueberries. You can mash them as much or as little as desired.
Step 4: Add in the lemon juice, stir, and return to heat. Bring the mixture to a boil. Remove from heat again.
Step 5: Stir in the chia seeds and honey and allow to cool.
Step 6: Pour into an airtight container and keep stored in the fridge for up to 2 weeks. Jam should be fully thickened and ready to use after 4 hours in the fridge.
🍴 Recipe Tips
Takes Time to Thicken
This no sugar blueberry jam recipe will thicken as it cools and chills, so if your jam still feels a tad thin while warm, don't worry. Give it a few hours in the fridge, and it will be set perfectly.
You can add in a little more sweetener if desired. Some blueberries are much sweeter than others, so definitely adjust to your tastes, as you may not want a tart jam.
You don't have to store the jam in a mason jar with a lid. You can use any other airtight container. If you do use a mason jar, make sure to wipe the rim well before applying the lid and ring.
If you don't, the jam will harden and make it troublesome to open the jar later. A warm washcloth along the outside of the jar is perfect for cleaning up any spills after filling.
