Ingredients for Keto Blueberry Syrup
This low carb blueberry syrup consists of frozen blueberries, water, sweetener, and a bit of thickener. Here's a breakdown of the key ingredients:

- Blueberries: Frozen or fresh blueberries work well in this recipe. Frozen blueberries are often more readily available, especially during the off-season.
- Sweetener: I recommend a mix of both Swerve and allulose for a more syrupy consistency. Keto syrups benefit from using at least some allulose, as it behaves a little more like real sugar and thickens as it cooks. I like to use a mix of allulose and an erythritol based sweetener. But you can use allulose as the only sweetener (you would need ⅔ cup). If you use an erythritol based sweetener by itself, the syrup may recrystallize a little as it cools. And the sweetener may settle out toward the bottom of the bottle. You can simply shake the bottle to mix it up again.
- Glucomannan: This thickening agent is a great low carb alternative to cornstarch.
- Lemon juice: Adds a touch of brightness and enhances the blueberry flavor.
- Vanilla extract: Complements the blueberry flavor and adds a hint of warmth.
Making Keto Blueberry Syrup: Step-by-Step
Best of all, you can make this delicious treat in about 15 minutes from start to finish. I give you two ways to make this delicious keto blueberry syrup. You can strain it for a true syrup, or leave in the mashed berries for a delicious sauce.
- In a medium saucepan over medium heat, combine the blueberries, water, and sweeteners. There is no need to thaw the berries before cooking. Just add them to the pot with the water and sweeteners, and start cooking.
- Bring to a boil. Reduce the heat to a low simmer and cook 10 minutes. Stir in the vanilla extract. Remove from heat and use a fork to mash the berries a little. Sprinkled the surface with the glucomannan, whisking briskly to combine.
- For a clear syrup, strain the mixture through a fine mesh sieve after step 2. Press on the solids to release as much juice as possible. If you want to strain the mixture for a proper syrup, don’t add the vanilla extract or glucomannan until afterwards. Return the juice to the pot, stir in the vanilla, and then whisk in the thickener.
- Let cool completely.
Variations and Tips
- Adjusting Sweetness: Start with less sweetener and add more to taste after the syrup has cooked down a bit.
- Adding Spices: Experiment with adding a pinch of cinnamon, nutmeg, or ginger for a warm and comforting flavor.
- Lemon Zest: Add lemon zest for a more intense lemon flavor.
- Thickening: If the syrup is not thick enough, add a pinch of xanthan gum.
- Fresh vs. Frozen: Using fresh blueberries is certainly best, but if you can only find them frozen, by all means use them.
Serving Suggestions
