Ingredient List for This Sugar Free Blueberry Jam Recipe
You can pick these simple ingredients up at your local grocery store.
- Frozen Blueberries: Frozen blueberries give you the perfect amount of liquid and fruit. By the way, I haven’t tried making this with fresh blueberries.
- Lemon Juice: Lemon juice adds a bright tang and acts as a natural preservative to help the jam last longer.
- Water (Optional): A splash of water helps loosen the mixture if it’s too thick while cooking.
- Cinnamon: Cinnamon adds a warm, spiced note that enhances the blueberry flavor, giving the jam a taste reminiscent of blueberry pie.
- Vanilla Extract (Optional): Vanilla brings a subtle sweetness and depth to this sugar free blueberry jam recipe.
- Natural Sweetener of Choice (Optional): Monk fruit sweetener is a keto-friendly sugar substitute that boosts the jam’s sweetness without added sugar. You can, however, make the recipe with natural sugar – or even as a low sugar blueberry jam recipe.
How to Quickly Make Sugar Free Blueberry Jam
- Prepare your blueberries: Take the frozen blueberries out of the freezer a few hours before making the jam. This allows them to thaw and become soft and juicy.
- Start cooking the blueberries: Add the blueberries to a small or medium-sized nonstick saucepan. The thawed berries should release plenty of liquid. So, begin by cooking them over medium heat in their own juices. Add 1 tablespoon of water only if needed. Once the berries have broken down, stir in the lemon juice and continue cooking for a few more minutes.
- Mash or blend the berries: As the berries heat up, they’ll continue to soften. If desired, use a spoon, potato masher, or handheld immersion blender to mash them to your preferred texture.
TIP: Use an immersion blender in short bursts to avoid fully pureeing the jam, leaving chunks of fruit and texture. - Add the cinnamon and sweetener (optional): Add a ½ teaspoon of cinnamon. Then, add 1-2 tablespoons of sweetener gradually until you reach the desired sweetness.
- Simmer the mixture: Reduce the heat to low. Let it simmer for about 15 minutes. Stir often to prevent burning.
- Taste: Add another ½ teaspoon of cinnamon if desired. Then, add more sweetener, if needed, to suit your taste, and cook for a few more minutes until the sugar dissolves.
- Cool the jam: Remove the saucepan from the heat and let the jam cool for 5–10 minutes before transferring it to jars. It will continue to thicken as it cools.
- Store in jars: Transfer the jam into a clean jar, mason jar, or container. Allow it to cool for about 30 minutes before sealing. Once sealed, refrigerate – preferably overnight – to give it time to set properly.
That’s it! Your sugar free blueberry jam is ready.

Cathy’s Recipe Tips
- Don’t skip the lemon juice, since it balances the flavor.
- Vanilla adds warmth but is totally optional.
- Taste before sweetening, since the blueberries may be sweet enough.
- Start with small amounts of sweetener.
- Let the jam sit overnight in the fridge. It thickens even more after chilling.
- You can double or halve the recipe easily.
- Stir constantly to avoid burning at the bottom.
Variations
You can easily switch up this sugar free blueberry jam recipe. Here are some tasty ideas to try:

- Herbs: You can also experiment with herbs, like thyme or basil. Always taste-test as you go.
- Lavender Blueberry Jam: Place ½ teaspoon of dried culinary lavender in a tea infuser for easy removal. Steep it in the jam while it simmers, letting it infuse for 5–10 minutes, depending on how strong you want the flavor.
- Mixed Berry Jam: Use a blend of blueberries, strawberries, raspberries, or blackberries. Stick to 4 cups of total fruit for best results.
- Spicy Blueberry Jam: Add a pinch of cayenne or a few crushed chili flakes. It creates a unique sweet-spicy combo.
- Vanilla Almond Blueberry Jam: Add vanilla and a few drops of almond extract. This gives it a bakery-style flavor twist.
