We love jams and jellies and making our own batch homemade sugar free strawberry jam here and there has been a great summer favorite for a few years. Using fresh berries while they're on sale and in season is a great way to stretch the budget but even frozen berries will work too!

Making your own sugarless strawberry jam is truly easy and doesn't require much work at all. It will however require a bit of patience to get the jam to the perfect consistency so if you've got berries to use and about 15 minutes to watch a pot on the stove, you're going to be in for a treat.
🥘 Ingredients
- Strawberries: You just need 1 pint of freshly washed, hulled, and quartered strawberries.
- Water: Only a small amount may be needed.
- Chia seeds: Instead of using pectin or other thickeners we choose chia seeds because they're incredibly healthy. Packed with fiber and omega 3's you're getting hidden nutrients in every bite.
- Lemon juice: This is what's needed to help preserve the jam so that it can last about a week or two in the fridge.
- Sweetener: You can use maple syrup or honey as a sweetener for your jam. I recommend honey but if you have real maple syrup (not the cheaper flavored corn syrup stuff), it will work great too.

🍴 Recipe Tips
This no sugar strawberry jam can be made to fit your desired level of chunkiness. If you like your strawberries bigger and more like preserves, don't mash as much as you would for a smoother jam consistency.
The longer the chia seeds sit in the jam the more they expand and help to thicken the jam. While they might look like added strawberry seeds you can make them into a finer texture by running them through a food processor until finely ground and then adding them into the jam.
Your jam might be slightly thin as it comes out of the pot but store it in an airtight container in the fridge for a few hours and it will thicken up wonderfully.

🔪 Instructions
Check out how to make sugar free strawberry jam with these simple step-by-step instructions:
- Wash and hull your fresh strawberries before cutting them into quarter-sized pieces.
- Add your strawberries to a medium-sized saucepan and cook for about 6-8 minutes over medium heat, until the berries are pretty soft.
