This Strawberry & Raspberry Chia Jam is a delicious, healthy twist on traditional jam, with a lower sugar content and all the fruity goodness. Made with ripe strawberries and raspberries, it’s naturally sweetened and thickened with chia seeds for a boost of fibre and omega-3s. Perfect for spreading on toast, adding to yogurt, or stirring into smoothies, this jam is as versatile as it is tasty. Best of all, it’s vegan and simple to make, giving you a homemade, guilt-free treat!

Make This Delicious Chia Seed Jam in Just 10 Minutes
Strawberry and raspberry are brought together in a deliciously juicy combo. Sweetened with coconut sugar and thickened with chia seeds, this Strawberry & Raspberry Chia Jam recipe is low in sugar so you can enjoy it without guilt.
Conventional jam uses up to a sugar/fruit weight ratio of 1:1. In this recipe that would equal to 300-400g of sugar. Instead, this chia jam contains only 3 Tbsp of coconut sugar. Because it is so low in sugar, do not expect it to be as thick as regular jam. If you want to increase the thickness, just add another tablespoon of ground chia seeds.
Sugar acts as a thickener and preservative so I always make low sugar preserves in small batches of 1 to 2 jars to avoid them going bad.
Troubleshooting Tips
Chia seed jam is more forgiving than conventional jam. But if things do not go according to plan, here are a few tips:
- Jam is too runny: Add more chia seeds (1 teaspoon at a time) and allow more time for thickening.
- Jam is too thick: Stir in a little water or fruit juice to thin it out.
- Seeds are clumping: Ensure you stir well while cooking and as the jam cools to distribute seeds evenly.
- Jam is too sweet or tart: Adjust sweetness with more fruit (for tartness) or sweetener (for sweetness).

- To sterilise the jars you can plunge them in a large pan of boiling water for 10 mins. Alternatively you can also wash them in warm soapy water, rinse them and put them on a baking tray in the oven heated up at 100°C/225°F/gas ¼ for 10 mins. Make sure everything is very clean.
