This low-carb blueberry chia jam is such a great way to enjoy berries. You'll only need a few ingredients and less than 30 minutes to make it. It's a tasty addition to our low-carb jams made with low sugar fruits including strawberries, raspberries, blackberries, rhubarb and cherries.

Blueberries are naturally sweet so you can keep it sweetener-free or use healthy low-carb sweeteners such as erythritol, Swerve, allulose, stevia or monk fruit.

Wild blueberries, which are typically smaller and less sweet than cultivated blueberries, are a better option for keto as they are high in antioxidants and contain less sugar. It may not be possible to find fresh wild blueberries but you can get them frozen — both fresh and frozen will work in this chia jam.

Serve this sugar-free jam just like your regular blueberry jam; with full-fat yogurt, coconut yogurt or sour cream, or on a slice of freshly baked keto bread. You can even use this chia jam as topping in all sorts of keto desserts like panna cotta, cheesecakes, cupcakes and pies. Enjoy!

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.

I can’t eat this in a week. Could I freeze some?

Hi Lisa, this will freeze well for up to 3 months. You can use an ice tray for that - I hope this helps!
