Low Carb Sugar-Free BBQ Sauce

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. Traditionally, BBQ sauce has a high carb count due to sugary ingredients. While I had found some keto-friendly store-bought options, nothing compared to my Daddy’s homemade recipe. So, I decided to use his recipe and make a keto version! After experimenting, I found the perfect combination of low-carb ingredients to make the best sugar-free bbq sauce recipe.

This keto BBQ sauce is easy to make with only six main ingredients! It is versatile and can go on any of your favorite meats, be used as a dipping sauce, or even go in some low-carb casseroles!

Is BBQ Sauce Sugar-Free?

No, traditionally, bbq sauce contains ketchup, brown sugar, and high fructose corn syrup, which has tons of sugar. With around 15 carbs per two tablespoons, it is not keto-friendly.

Will BBQ Sauce Kick You Out of Ketosis?

Since regular BBQ sauce contains so many sugary ingredients, it would not take much to kick you out of ketosis. However, you do not have to miss this sugar-free keto bbq sauce recipe!


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 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.Picture of Monkfruit Sweetener Picture of Low Cab BBQ Sauce

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 brown sugar substitute that works perfectly in keto recipes. An alternative sweetener is Swerve Brown. Lakanto Monkfruit Golden and Swerve Brown measure the same and are interchangeable.

How to Make Homemade Sugar-Free BBQ Sauce

Step One: Add tomato sauce and mustard to a saucepan and use a whisk to stir vigorously to ensure the ingredients are thoroughly combined. Don’t skip the whisking. You want to make sure your low-carb sauce will be smooth!

Tip: The canned tomato sauce is located in the canned food aisle, usually with several varieties of canned tomatoes, such as diced, whole, tomato paste, etc. With all the tomatoes next to each other, it is easy to grab the wrong kind, so you may want to double-check before checking out!

Step 2: Dump the spices, water, vinegar, and Monkfruit Golden into the mixture and stir together. Turn on medium-high heat to bring it to a boil. sugar free bbq sauce with a whisk in the pot

Step 3: Once the sauce comes to a boil, reduce it to a simmer on medium heat. While simmering, the sauce will begin to reduce and thicken and infuse with flavor. Leave on the stove until it has reached the desired thickness. Serve and Enjoy!

Tip: If you feel like the bbq sauce is too thin, don’t take it off the stove yet. All you have to do is keep simmering with the lid oof the pot and it will thicken perfectly.

Variations to Low Carb BBQ Sauce:

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 recipe for sugar-free bbq sauce include liquid smoke, Worcestershire sauce, smoked paprika, onion powder, and chopped onions. 

In addition, if you want to make spicy sugar-free bbq sauce add cayenne pepper and a dash of your favorite ket-friendly hot sauce!

How to Thicken Homemade Sugar-Free BBQ Sauce:

To thicken, all you have to do is let it cook down and simmer for a bit; this does not take too long but is incredibly important as it allows the flavors to infuse together. If you are in a time crunch or the sauce is not thickening, you can turn up the stove (make sure to watch it carefully so it doesn’t boil over or stick), or add about 1/4 tsp of xanthan gum. You have to be careful not to use too much xanthan gum as it can make the texture slimy if you use too much. I prefer boiling it down on the stove instead.

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. 

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 Many Carbs are in Sugar-Free BBQ Sauce?

This recipe only has one carb per serving of two tablespoons, making it the perfect keto sauce option! Having tomato sauce replace ketchup and a keto-friendly sweetener instead of brown sugar dramatically reduces the number of carbs!

How to store this recipe?

I store it in the refrigerator 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.

You can also place the sauce in an airtight container and freeze it for up to 3 months if you wish!

To reheat low carb bbq sauce, you can either warm it up in a glass container in the microwave at 30-second intervals stirring between each one or add it to a saucepan on low and heat until the desired temperature. Let it defrost in the fridge overnight before reheating for best results.

What Do I Serve Low-Carb Sugar Free BBQ Sauce on?

Being from the south, I can eat keto BBQ sauce on anything, but some of my favorite ways to serve are on top of chicken, beef, ribs, or even in a casserole. Below I have added links to my favorite dishes and low-carb bbq meals:

Are there store-bought bbq sauces that are sugar-free?

    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.

    1. The canned tomato sauce is not a marinara sauce. You’ll find it in the canned food section with tomato paste and diced tomatoes. The flavor profile of a marinara sauce is very different than bbq sauce.
