Quick 4-Ingredient Blackberry Chia Jam
This homemade jam only takes about 10 minutes to make with super simple ingredients! It’s just like my Raspberry Chia Jam, but made with blackberries. You could even top a dollop of this onto my Berry Crumble.
What to Expect: This blackberry chia jam is thick, fruity, and slightly seedy from both the blackberries and chia seeds. It’s not as firm or glossy as traditional pectin-based jam, but it has a fresh berry flavor and a soft, spreadable texture.
Here’s why you’ll love it:

Ingredient Notes
All you need for this healthy jam recipe is a few whole foods!

Don’t forget to scroll down to the recipe card for the full ingredients list and directions.
- Blackberries: Fresh blackberries or frozen both work perfectly for this jam. Fresh berries usually give the best texture, while frozen berries make it easy to make year-round. If using frozen blackberries, cook them until fully thawed and juicy, and simmer a little longer if the mixture looks thin.
- Lemon juice: A little bit of lemon juice adds brightness to the jam and balances the sweetness of the fruit and honey. You can also use lime juice or orange juice.
- Honey: You can customize the amount of sweetener to your personal preference! Honey and blackberry is a delicious combination but pure maple syrup or sugar free syrup will also work here.
- Chia Seeds: These little seeds thicken this jam for the perfect consistency, just like in chia seed pudding. The health benefits of chia seeds are worth mentioning too- they’re filled with heart-healthy soluble fiber and omega-3 fatty acids!
Variations To Try
- Adjust the chia seeds: Use 1.5 to 2 tablespoons of chia seeds for a thinner jam, or 3 tbsp for a thicker jam.
- Blackberry Greek yogurt parfait: Layer 1 cup Greek yogurt, this homemade blackberry jam and my Vanilla Nut Granola Recipe!
- Swap the berries: You can use raspberries, strawberries or even wild blueberries for this recipe. All types of berries work!
- Make it smoother: If you want more of a seedless blackberry jam texture you can put the blackberries through a fine mesh sieve before adding the chia seeds. You can also blend the jam in a food processor for a smoother texture.
- Blackberry vanilla jam: Add a teaspoon of vanilla extract for a rich vanilla flavor.
- Blackberry pie parfait: Serve with vanilla Greek yogurt and top with graham cracker crumbs for a fun spin on blackberry pie.

Jamie’s Tips
Expert Recipe Tips
- Mash the berries as they cook. This ensures a smooth texture.
- Let the jam rest. After simmering, let the jam sit for 10-15 minutes so the chia seeds can thicken.
- Add more chia seeds for thicker texture. If you want a thicker texture, you can mix in more chia seeds.
- Add extra honey. If your berries are tart, you can add extra honey to sweeten the jam.
- This is refrigerator jam, not shelf-stable canned jam. It must be stored in the refrigerator.

How To Store
Store leftovers in an airtight container or jam jar with lid in the fridge for up to 7 days. Note: This jam should NOT be canned or stored at room temperature.

We picked some fresh blackberries and I needed to use them up. I made your Berry Crumble and a batch of this jam. I mix it into cottage cheese and my kids love it on toast.
