2-Ingredient Blueberry Jam
This incredibly simple 2-ingredient blueberry jam is made without any added sugar, relying on the natural sweetness of wild blueberries and the thickening power of chia seeds. It's a quick, healthy spread perfect for toast, oatmeal, or yogurt.
For 4 servings
Place the frozen wild blueberries in a small, heavy-bottomed saucepan over medium heat. There's no need to add water as the berries will release their own liquid as they thaw.
Cook, stirring occasionally, for 5-7 minutes, until the blueberries begin to burst and release their juices. Use the back of a spoon or a potato masher to gently mash about half of the berries, leaving some whole for texture.
Reduce the heat to low. Add the chia seeds to the saucepan and stir thoroughly, ensuring they are evenly distributed and no clumps remain.
Continue to cook for another 1-2 minutes, stirring constantly, allowing the chia seeds to hydrate slightly and the mixture to begin thickening.
Remove the saucepan from the heat. Carefully pour the hot jam into a clean, heat-proof, airtight jar or container.
Allow the jam to cool completely at room temperature. As it cools, the chia seeds will fully absorb the liquid, creating a thick, jam-like consistency.
Once cooled, cover the jar tightly and refrigerate for at least 1 hour before serving. The jam will continue to thicken as it chills in the refrigerator.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1For a smoother jam, use an immersion blender or transfer the mixture to a regular blender (after cooling slightly) before adding chia seeds. Then return to the pan, add chia, and proceed.
- 2Adjust consistency: If the jam is too thick after chilling, you can stir in a tablespoon of water or fruit juice. If it's too thin, add another 1/2 teaspoon of chia seeds, stir well, and refrigerate for an additional hour.
- 3Storage: This jam can be stored in an airtight container in the refrigerator for up to 1-2 weeks. It does not have the shelf stability of traditional sugar-laden jams.
- 4Serving suggestions: Beyond toast, try it swirled into oatmeal, mixed into yogurt, as a topping for pancakes or waffles, or even as a healthy ice cream topping.
Adapt it for your goals.
Fruit Swap
Experiment with other frozen berries like raspberries, strawberries, or a mixed berry blend for different flavor profiles. Adjust cooking time slightly depending on the berry type.

Frequently asked questions
Yes, you can use fresh blueberries. They might require a tiny splash of water (1-2 tablespoons) at the beginning to help them break down and prevent sticking, as they won't release as much liquid as frozen berries initially.
