Add the peaches, lemon juice, and sweetener to a medium saucepan over medium heat.

Cook for 5 to 7 minutes, stirring occasionally, until the peaches soften and release their juices.

Mash the peaches using a potato masher for a chunky texture.

For a smoother jam, blend the mixture with an immersion blender.

Remove the saucepan from the heat.

Stir in the chia seeds and any optional flavor additions.

Allow the mixture to rest for 5 to 10 minutes.

Transfer the jam to clean jars or airtight containers.

Refrigerate until fully set before serving.

White chia seeds help preserve a bright golden color.

Frozen peaches may require 2 to 3 extra minutes of simmering.

Ground chia seeds create a smoother texture and set faster.

Store in the refrigerator for up to 14 days.

Freeze for up to 3 months, leaving 1 inch of headspace.
