Cook the Blueberries – In a small saucepan over medium heat, add the blueberries. Stir occasionally and cook until they begin to release their juices, about 5–7 minutes.

Mash & Sweeten – Use a fork or potato masher to lightly mash the blueberries to your desired consistency. Stir in the monk fruit sweetener and continue cooking for another 2–3 minutes.

Add Flavor – Stir in the lemon juice and vanilla extract to brighten and enhance the blueberry flavor.

Thicken with Chia Seeds – Sprinkle in the chia seeds and stir well. Let the mixture simmer for 3–4 minutes until it begins to thicken.

Cool & Store – Remove from heat and allow the jam to cool completely. As it cools, the chia seeds will continue to thicken the mixture. Transfer to a clean jar and refrigerate.
