Trim the stems from the strawberries and cut them in half. Place the strawberries and maple syrup in a blender or food processor and pulse until you reach your preferred consistency. You can leave it slightly chunky or blend until smooth.
Transfer the strawberry mixture to a saucepan and stir in the chia seeds. Place over medium heat and bring to a gentle bubble, stirring occasionally.
Reduce the heat to low and simmer for 10–15 minutes, stirring occasionally, until the mixture begins to thicken.
Remove from the heat and let cool. The jam will continue to thicken as it cools.
Transfer to a clean jar and refrigerate for up to 7 days. Freeze for longer storage.
