Reader Feedback
⭐⭐⭐⭐⭐ Loved everything about this recipe. Easy to follow and great idea to make during Blueberry season. I’m currently following the Candida diet so I substituted Monk fruit for the maple syrup. It worked out great! I would definitely make this again. Thank you so much for posing this healthy recipe! : ) – Joanne

Ingredients + Substitutions
All you need is 3-4 ingredients to make this delicious blueberry chia jam.
- Blueberries: Fresh, in-season blueberries taste best, but frozen work as well.
- Lemon: You will need both the zest and juice from a large lemon. Make sure to zest the lemon first, and then juice it.
- Chia seeds: You may use white or black chia seeds, and if you don’t like the texture of chia seeds, you may grind them before adding to the jam.
- Maple syrup: This is optional and will depend on the sweetness of your blueberries. If the blueberries are fresh and in season, you can skip the added sweetener. You may also use date syrup or another sweetener of your choice.
Instructions
(This is a summary with step by step photos, full recipe measurements and instructions are in the recipe card below.)
Add the blueberries, lemon zest + juice, and maple syrup, if using, to a medium saucepan. (photo 1)
Simmer until the blueberries start to burst, and then gently mash with a potato masher. (photo 2)
NOTE: Don’t overly mash into a puree. Some blueberry pieces throughout will add nice texture.
Increase the heat and boil to slightly reduce the mixture. Then turn off the heat and stir in the chia seeds.
Transfer your blueberry chia jam into clean jars for storage.
Storage
When your jam is ready, it will be very hot. So use caution to carefully transfer it to clean and dry glass jars. And don’t worry if it appears a little thin, the chia seeds will absorb the excess liquid as it cools.
This blueberry chia jam recipe makes about 2 cups worth of jam. It will keep refrigerated for up to 2 weeks, so separate it into portions that you will consume within that time frame.
NOTE: If you’re skipping the lemon, the jam won’t keep as long.
I use two small jars and keep one in the fridge for immediate consumption (once cooled for several hours), and the other in the freezer to use later.
The frozen jam will keep for up to 6 months.
How to use it
- Spread onto toast, crumpets, or bagels.
- Make a peanut butter and blueberry chia seed jam sandwich.
- Stir some into your oatmeal, yogurt, or chia pudding.
- Spoon it over pancakes, waffles, brownies, or ice cream!
Expert Tips
- You need 1 large lemon for both the zest and juice. Make sure to zest your lemon before juicing it.
- Don’t overly mash the jam into a puree. Some blueberry pieces throughout will add a nice texture.
- If the jam seems thin after boiling, not to worry. The chia seeds will absorb most of the excess liquid as it cools.
- For a smoother texture (if you don’t like the chia texture), grind the chia seeds before adding them to the jam.
- Try it with other berries like raspberries and/or blackberries. Or try our strawberry version here.

Can you store this by canning the jam after it’s made? If so, any instructions?
Rosa
Hi Celeste, here are some directions on canning in my apple butter post. You can follow the same method for the jam. Enjoy 🙂 Just keep in mind it won’t last as long as freezing since the jam is thickened with chia seeds, and not sugar or pectin.
Fifi
I’m love! I really liked this recipe. Was quick and easy and deliciously honestly the best one I’ve tried so far.
Rosa
Thrilled to hear that! 🙂

I do this with strawberries and it’s amazing.I hate store jam as it’s super sweet and taste nothing like the jam I remember eating when I was a kid.
Lisa
Can you do this with other fruit? Apricots?
Rosa
I haven’t tried apricots, but it may work. Make sure to dice them first if you give it a try.
Nory
This chia jam is to die for. I did have to add a couple teaspoons of cornstarch to get it to thicken. I’m eating it right now swirled in whole grain porridge with peanut butter. Yum!
For any readers who are reluctant to make the jam because of a short storage time, don’t worry. I’ve had my jam in the fridge for several months with no impact on quality.
Thanks so much for the wonderful recipe!
Rosa
That’s fantastic Nory. Thanks very much for the detailed review. Thrilled you’re enjoying the jam. 🙂
Elaine
Could I substitute other berries or a combination of berries? Would the recipe remain the same?
Rosa
Yes, you may use other berries. Here’s our strawberry version, or have fun experimenting with other berries. Enjoy.

If you want it sweeter add Monk sugar which adds sweetness but not the carbohydrates. The body does not recognize Monk sugar as a carbohydrate and does not metabolize it as a sugar. Research monk sugar, it is really a wonderful phenomena in which it also prevents cancer and lowers blood sugar levels.
