Low Carb Sugar-Free BBQ Sauce

I think I have missed homemade BBQ more than I realized. Growing up, my parents made homemade BBQ sauce all the time. I can even remember my Daddy standing over a hot pot of BBQ sauce, tasting it by the spoonful until it was just right. I’m pretty sure BBQ sauce was a food group all its own in my family since we ate it so often.

Although I have found store-bought sugar-free bbq sauce that tasted okay, nothing compares to homemade. A while back, I started experimenting with my family’s BBQ Sauce recipe as I knew there had to be a way to make a low-carb, sugar-free BBQ sauce version. It was a bit tricky since BBQ is very sweet and is usually made with quite a bit of ketchup and brown sugar, which I avoid due to the high carb count. I used regular tomato sauce in this recipe and then sweetened it with MonkFruit Golden Sweetener (a sugar-free brown sugar substitute). It tastes just like my family’s homemade sauce.

If you are making something with BBQ, you need to serve it alongside this easy keto coleslaw!


Tomato Sauce – This tomato sauce creates the base for sugar-free barbecue sauce without adding a lot of sugar.
Mustard – Helps tone down the tomato taste.
Vinegar – Gives it that famous delicious tang to this sugar-free bbq sauce recipe.
Water – Adds extra liquid so the sauce can be simmered and reduced, intensifying all the flavors.
Lakanto Monkfruit Golden – A sugar-free sweetener that makes this keto bbq sauce low in carbs.
Braggs Aminos – Braggs is a healthier version of soy sauce. It gives a little boldness to the flavor.
Chili Powder/Garlic Powder/ Salt/Pepper – Flavor is the name of the game when you make dipping sauces. Don’t skimp, or you’ll miss the fantastic flavor.

Will BBQ Sauce Kick You Out of Ketosis?

Regular BBQ sauce generally has approx 15 carbs in two tablespoons. It wouldn’t take much to go over your daily carb allowance. Since it is made with pure sugar and often high fructose corn syrup, it would likely kick you out of ketosis; that is why I made this fantastic sugar-free bbq sauce keto-friendly.

Specialty Ingredients Used in this Recipe:

As I had mentioned before, regular BBQ Sauce is loaded with sugar. When making a keto-friendly version, an excellent sugar-free substitute is an essential ingredient. In creating this recipe, Lakanto Monkfruit Golden Sweetener yielded the best results. It is a fabulous sugar-free substitute for brown sugar that works perfectly in keto recipes. An alternative sweetener is Swerve Brown. Lakanto Monkfruit Golden and Swerve Brown measure the same and are interchangeable.

Step One: Use a whisk and stir vigorously to ensure the tomato sauce and mustard are thoroughly combined before adding the rest of the ingredients to ensure that the sauce is smooth.

Tip: You’ll find the canned tomato sauce in the canned food aisle at your local grocery store. It is usually stocked with varieties of canned tomatoes, such as diced, whole, tomato paste, etc.

Step 2: Dump the rest of the ingredients in the pot and stir it. Don’t be afraid of spices. Spices like chili powder and garlic powder can add depth and flavor to recipes. Together with the water, vinegar, and Monkfruit Golden, they blend to create a rich, bold, and tangy sugar-free BBQ sauce that is perfect for a low-carb diet.

Variations to this Recipe:

While I used regular white vinegar in this recipe, you could substitute it with apple cider vinegar. Additional ingredients that can be added to this great recipe for sugar-free bbq sauce include liquid smoke, Worcestershire sauce, smoked paprika, onion powder, cayenne pepper, and chopped onions.

Can I Make This Recipe in a Slow Cooker?

I don’t think it would work as sauces don’t typically cook down and reduce in a slow cooker. You need to boil the sauce down without a lid on it for it to thicken properly.

How to Thicken Keto BBQ Sauce

Step 3: Bring to a slow boil, then simmer on medium heat. The sauce will begin to reduce and thicken. All the flavors infuse together, making it incredibly bold and tangy. With only one net carb per serving, you’ll want to keep a batch of this sugar-free bbq sauce recipe handy in the refrigerator. You could add xanthan gum to thicken it more quickly, but it is unnecessary, and boiling it down makes it more flavorful.

Is this BBQ Sauce Gluten-Free?

All of the ingredients used to make this sugar-free bbq sauce are gluten-free. Although, I would suggest checking the labels on the brands you use.

Braggs Aminos is a healthier version of soy sauce that is naturally gluten-free and does not contain wheat, additives, or preservatives.

How to store this recipe?

I store it in the fridge for up to two weeks. I’ve saved empty ketchup bottles or mason jars to store the bbq sauce. The keto-friendly sweetener can crystallize when refrigerated, but once you heat the sauce, it will be nice and smooth again.

    1. I don’t personally use stevia in recipes as I find it bitter so I don’t know from experience how it would turn out or how much to use.

  1. 5 stars
    Wow I made this BBQ sauce last night and it is outstanding!! I also made your Monterey chicken recipe which was absolutely delicious!! I love your recipes, they are all easy and delicious!!

    1. Fantastic! I’m so glad you loved both the recipes and you’ve enjoyed others. I appreciate your taking the time to comment and rate the recipe.

  2. I’m making my second batch now! This time I’m using fresh garlic and a bit of liquid smoke which I saw in a previous comment. This one is a winner and a great way to make boring cuts of meat meat a little more exciting!

    1. Fantastic. So glad you loved it. It is my favorite bbq sauce recipe. I’d appreciate it if you’d jump back on the recipe and give it a rating with the stars since you loved it.

  3. How long does this keep? Wanting to make it but I also don’t want it going bad before I can use it up with other recipes.
    Thank you

    1. I usually keep it in the fridge for about two weeks or so if we don’t use it all by then.

  4. 5 stars
    After making this four times I thought I’d come by to leave a comment. This is a great recipe and I am glad I found it. I’ve been using the Swerve Brown sugar replacement and have also added some onion powder, and liquid smoke to it in the last batch. Delicious. I eat this on Chicken and Pork chops and it really makes my brain think I’m cheating! The other nice thing about this sauce is the smell in the house when its simmering.. I keep “having to” taste it along the simmering process. Very good recipe. Thank you!!

    1. Awesome, Joey! I remember my daddy making this recipe (except with regular sugar) when I was a little girl. The entire house would smell so good and he’d get spoonfuls to taste every so often just to make sure it was perfect. I’m so glad you enjoyed it.
