Do yourself a favor and head to the store for some blueberries. More specifically, grab a bag (or two or five) of frozen Oregon Blueberries. Because this keto blueberry syrup is just the thing to take your winter breakfast to the next level. 

Once again, Oregon Blueberry Growers have brought us their finest. The sweet flavor and deep color of this low carb blueberry syrup says it all. It’s simply divine over keto pancakes and waffles.

Why you need to try this recipe

But don’t limit yourself to serving it at breakfast! It’s also amazing atop keto cheesecake or as a sauce for low carb ice cream. And you can leave the blueberries in for a thicker sauce, or strain them out for a thinner syrup.

The syrup is also a great way to make cocktails and mocktails. Try adding a few tablespoons of syrup to a glass of seltzer for a refreshing beverage. Or make a festive vodka spritz with a little fresh rosemary.

And it makes a lovely hostess gift. Bottle it up in pretty bottles or nice jars and tie a vanilla pod on with a ribbon.

Best of all, you can make this delicious treat in about 15 minutes from start to finish. And it has only 2.4g carbs per serving.

Ingredients you need

• Frozen Oregon Blueberries: Did you know that Oregon is one of the top blueberry producing states? Those plump, juicy berries love our climate! 
• Sweetener: I recommend a mix of both Swerve and allulose for a more syrupy consistency. See the Expert Tips for more information. 
• Vanilla extract
• Glucomannan: This thickening agent is a great low carb alternative to cornstarch. You can also use xanthan gum.

Step by Step Directions

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. Either way, it’s tasty stuff! 

1. In a medium saucepan over medium heat, combine the blueberries, water, and sweeteners. Bring to a boil. 
2. Reduce the heat to a low simmer and cook 10 minutes. Remove from heat and use a fork to mash the berries a little. 
3. Stir in the vanilla extract. Sprinkled the surface with the glucomannan, whisking briskly to combine. Let cool completely.  
4. 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. Return the juice to the pan and stir in the vanilla, then whisk in the glucomannan.

Expert Tips

There is no need to thaw the berries before cooking. Just add them to the pot with the water and sweeteners, and start cooking. 

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.

I tried using real vanilla beans in this recipe, but the flavor got lost among those juicy berries. So vanilla extract works better.

Sweetener Options

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.

Other sweeteners, such as pure stevia or monk fruit extract, will add to the sweetness but not the consistency. So the syrup may be a little thinner.
