This easy sugar-free raspberry jam is perfect for anyone following a low-carb lifestyle. Made with just five simple ingredients, this homemade jam comes together in under 30 minutes!
Why I Love This Sugar-Free Raspberry Jam
I’ve always been a jam lover, but most store-bought sugar-free versions disappointed me. They’re loaded with artificial sweeteners and questionable ingredients that I’d rather avoid.
That’s when I decided to make my own version at home. I wanted something simple, natural, and delicious that I could feel good about eating.
The secret ingredient? Chia seeds! These tiny superfoods create the perfect jam-like texture while adding fiber and nutrients. The result is a thick, spreadable jam that tastes amazing on everything.

I love this recipe because it’s so versatile. You can use fresh or frozen raspberries, which means you can make it year-round. The best part is that it only takes about 25 minutes from start to finish.
When I first tasted this raspberry chia jam, I was amazed. The flavor is bright and fruity, with just the right amount of sweetness. It’s so good that you might find yourself eating it straight from the jar!
Why This Recipe Works
Traditional jam recipes rely on tons of sugar to thicken and preserve the fruit. This recipe takes a completely different approach that’s healthier and easier.
Chia seeds are the game-changer here. When mixed with liquid, they expand and create a gel-like consistency. This natural thickening power means we don’t need pectin or excessive sweeteners.
Raspberries are naturally lower in sugar compared to other fruits. They’re also packed with antioxidants and have a bold, tangy flavor that doesn’t need much enhancement.
The small amount of sweetener I’ve included balances the tartness perfectly. You can adjust it based on your taste preferences and the sweetness of your berries.

Let’s Talk About Each Ingredient
Raspberries I use both fresh and frozen raspberries with excellent results. Frozen berries are often more affordable and available year-round. Since we’re cooking them anyway, there’s no difference in the final texture.
Fresh raspberries work beautifully when they’re in season. Choose berries that are plump and deeply colored for the best flavor.
Sweetener I prefer Pyure All-Purpose sweetener because it measures like sugar and has a clean taste. Swerve is another excellent option that works perfectly in this recipe.
Both sweeteners are sugar-free and won’t spike your blood sugar. They blend seamlessly into the jam without any bitter aftertaste.
Water Just a tablespoon of water helps get the cooking process started. The raspberries release their own juices as they heat, creating plenty of liquid.
Chia Seeds These nutritional powerhouses do double duty in this recipe. They thicken the jam naturally while adding fiber, protein, and omega-3 fatty acids.
Either black or white chia seeds work perfectly. I often use white seeds in lighter-colored recipes, but it’s purely a visual preference.
Vanilla Extract A small amount of pure vanilla extract enhances the raspberry flavor beautifully. It adds depth and warmth to the finished jam.
COOKING INSTRUCTIONS & SERVING SUGGESTIONS
Quick Tips Before You Start
Choose quality chia seeds. Either black or white chia seeds work equally well. There’s no nutritional difference between the two colors.
Store it properly. Keep your finished jam in an airtight container in the refrigerator. It stays fresh for up to one month.
Adjust sweetness to taste. Start with the recommended amount of sweetener, then add more if needed. Different berries have varying natural sweetness levels.
Don’t skip the cooling time. The jam thickens significantly as it cools. What seems thin in the pan will become perfect spreadable consistency.
Make it in batches. This recipe is easy to double or triple. Make a larger batch and freeze portions for later use.
How To Make Sugar-Free Raspberry Jam At Home
Making homemade jam sounds intimidating, but this recipe is surprisingly simple. You’ll have delicious jam ready in just a few easy steps.
Step 1: Simmer The Berries
Add your raspberries, sweetener, and water to a small saucepan. Place the pan over medium heat and bring the mixture to a gentle boil.
The raspberries will start breaking down and releasing their natural juices. Use a wooden spoon to gently stir and help break up the berries.
Once the mixture reaches a boil, reduce the heat to low. Let it simmer gently while you prepare for the next step.

Step 2: Add The Chia Seeds
Sprinkle the chia seeds into the simmering berry mixture. Stir constantly to prevent clumps from forming. This is important for achieving a smooth texture.
Continue simmering the mixture for about 15 minutes. You’ll notice it starting to thicken as the chia seeds absorb the liquid. Stir occasionally to prevent sticking.
The jam is ready when it coats the back of your spoon. It should look thick and glossy, similar to traditional jam consistency.
Step 3: Cool The Jam And Store It
Remove the saucepan from the heat and stir in the vanilla extract. This adds a lovely aromatic note to the finished jam.
Let the jam cool completely in the pan. As it cools, it will thicken even more. This is the chia seeds working their magic!
Once cooled, transfer the jam to a clean, airtight container. A mason jar works perfectly for storage. Keep it refrigerated for up to one month.
You can also freeze this jam for longer storage. It keeps beautifully in the freezer for up to one year. Just thaw in the refrigerator before using.

FAQs & CONCLUSION
Frequently Asked Questions About Sugar-Free Raspberry Jam
Can I use other berries instead of raspberries?
Absolutely! This recipe works well with many different berries. Strawberries, blueberries, and blackberries all make excellent jam using this method.
You can even mix different berries together for a custom blend. Mixed berry jam is delicious and uses whatever berries you have on hand.
Keep in mind that different berries have varying natural sweetness levels. You may need to adjust the sweetener slightly based on your chosen fruit.
How many net carbs are in this sugar-free jam?
This entire recipe makes about 28 tablespoons of jam. Each tablespoon contains approximately 1.9 grams of total carbs and 0.6 grams of fiber.
That means each tablespoon has only about 1.3 net carbs. This makes it perfect for low-carb and keto diets.
The chia seeds contribute most of the fiber, which helps lower the net carb count. They also add beneficial nutrients without adding sugar.
Are chia seeds good for low-carb diets?
Chia seeds are excellent for low-carb eating! One ounce contains about 12 grams of carbohydrates, but 11 of those grams are fiber.
This means they have minimal impact on blood sugar levels. The net carb count is very low, making them keto-friendly.
Beyond being low-carb, chia seeds offer impressive health benefits. They’re rich in omega-3 fatty acids, protein, calcium, and antioxidants.
When chia seeds absorb liquid, they expand significantly. This property makes them perfect for creating jam-like consistency without adding carbs.
What’s the difference between black and white chia seeds?
Nutritionally, black and white chia seeds are virtually identical. Both offer the same health benefits and thickening properties.
The only real difference is aesthetic. White chia seeds are less visible in light-colored dishes, while black seeds stand out more.
I use white chia seeds in this raspberry jam for a smoother appearance. However, black seeds work just as well if that’s what you have.
White chia seeds are sometimes slightly more expensive than black ones. Choose whichever fits your budget and preference.
How long does homemade sugar-free jam last?
In the refrigerator, this jam stays fresh for about one month. Always store it in an airtight container to maintain quality.
For longer storage, freeze the jam in portion-sized containers. It keeps perfectly in the freezer for up to one year.
To use frozen jam, simply transfer it to the refrigerator the night before you need it. It thaws beautifully and tastes just as fresh.
