Strawberry, basil and balsamic vinegar are a match made in heaven in this roasted strawberry & basil chia jam. This keto recipe and the my low-carb dark cherry Amarenata are hands down the best low-carb jams I've made since going keto. Roasting the strawberries in the oven rather than cooking them on the stove enhances the flavour, especially when paired with caramelised Swerve and balsamic vinegar.

Chia jams are low in carbs and ideal for those who struggle with blood sugar issues or follow a keto diet. I eat them with full-fat yogurt, coconut yogurt or sour cream. They're the ideal topping for all sorts of keto desserts like cheesecakes, cupcakes and pies.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Next time I’m going to use white balsamic vinegar. I thought it was too dark. Still tasty.


Thank you! It shouldn't make the jam really dark unless you used the syrupy type of balsamic vinegar? I used the thin, runny type of balsamic vinegar. I will try with white balsamic vinegar! 😊


Omg I just made this and I seriously think it’s the best jam I have ever had in my life!!  And with the 5 minute cheesecake it’s the best thing I have ever eaten!!!  Please tell me how I could go about canning this!!  I definitely want to make a larger batch to can but don’t k ow how to do that!!  Help!


Thank you SO much, it means a lot to me! I never preserved this jam - it disappeared before I ever got to it 😊 But I'd use the regular canning method  to preserve the jars (just Google "canning method preserves"). Or you could scoop it in an ice tray and freeze but I can't promise the texture will be the same after defrosting it.


I made a 1/2 batch of this last night to put on top of the Keto Cheesecake Cups. I ended up adding about 1 tsp of gelatin to thicken it a bit, and added about another 2 tsps of Erythritol to sweeten it up a little more to counter the strong taste of the balsamic vinegar I used. Everyone really enjoyed it!


I'm glad you enjoyed it, thank you for the tips!


Do you think it can be frozen?


Yes, I think you can freeze it. I either make a small batch and keep in in the fridge or preserve it if making a large batch (canning method).


Hi I was wondering if I could substitute gelatine in place of the chia seeds?


Yes you can do that but I would only be guessing on the amount (no more than 1/2 teaspoon). You'll need to let it bloom in 2 tablespoons of cold water before adding to the strawberries.


Hi there! This sounds awesome and I can’t wait to try it. Do you think I could can this like regular jam?


Absolutely! You can double or triple the batch and preserve it using a canning method. One batch will make two 8-oz jars.
