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!

Ingredients: 

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 adds a little boldness to the flavor.
Chili Powder/Garlic Powder/ Salt/Pepper — Flavor is the name of the game when making 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 stir vigorously to combine the ingredients. Don’t skip the whisking—you want to make sure your low-carb sauce is 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: Add the spices, water, vinegar, and Monkfruit Golden to the mixture and stir together. Bring it to a boil over medium-high heat. 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 on 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 apple cider vinegar. Additional ingredients that can be added to this sugar-free BBQ sauce recipe include liquid smoke, Worcestershire sauce, smoked paprika, onion powder, and chopped onions. 

In addition, if you want to make spicy keto 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. However, I 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! Using tomato sauce instead of 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, either warm it 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. For best results, let it defrost in the fridge overnight before reheating.

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?

Sure! If you don’t have time to make homemade, I’ve linked a few of the best store-bought sugar-free BBQ sauces below.

  1. Hi Kasey, this recipe sounds great! Do you have to store it in the refrigerator? How long will it keep.
    Also, I’m from Australia so some of our terms are different. By tomato sauce, do you mean concentrated tomato paste with no additives, or unconcentrated like you might use for a pasta sauce base (we call it passata).
    Thanks!

    1. Hi Jen, I do keep mine in the fridge for about 2 weeks. Tomato sauce is canned in the states and is not concentrated like tomato paste. I would guess it is much closer to the pasta sauce base that you mentioned.

    1. 5 stars
      Did you use Coconut Aminos? I tasted both aminos & decided to use the coconut instead of the soy! Also had to simmer the sauce for about 2 hours to cook out a lot of the liquid & thicken up.

  2. Hi, a silly question to ask. The mustard is that the actual yellow mustard in a bottle or the powdered seasoning mustard? Thanks for answering my silly question ?

    1. Another option is Swerve brown. Both Swerve brown and Monkfruit golden are sugar free brown sugar alternatives.

    2. I’ve only tested it as is. The monk fruit is a brown sugar substitute. Coconut sugar is the same thing as regular sugar so I don’t use it.

    1. Hi Kasey
      I was wondering if you would be able to please update your ingredients to reflect the vinegar type to use and the monk fruit gold alternatives option? I’m in the process as I type making this sauce and used apple cider vinegar instead of white vinegar so I’m hoping I haven’t no wasted a whole bunch of ingredients. Also, I’ve used erythritol as we don’t have monkfruit golden readily available in Australia.
      Thank you, Felicity

    2. Hey Felicity, I have only tested the recipe as is. I am not sure what products you have in Australia. Sorry!

  3. I love the gorgeous deep red color of your BBQ sauce, plus the fact that it’s sugar-free! I would love to whip up a batch of this and keep it stashed in the fridge for use on just about everything. 🙂

  4. Will it not last longer in the fridge for more than two weeks? Or is that the longest it will last and still taste good. Can i use soy sauce in place of Nraggs Aminos? Love the recipe.

    1. It doesn’t have any kind of preservatives so personally, I think that 2 weeks is as long as I will eat it, but you can go by taste if you’d like and use it longer if you are comfortable. Yes, if you are okay with soy sauce then that is fine.

  5. Hi Kasey, Is this something that can be frozen? I love it, I just can’t consume a full batch in 2 weeks…

    Thank you!
    Denise

    1. I’ve only made it as is so I can’t say from personal experience. Although, I have found that most things don’t tend to cook down very well in a crock pot.

  6. Have you had any trouble with it crystallizing in the fridge? I made this and so did my mom and both of ours had sugar crystals the next day.

    1. I always warm it back up before serving it again so I haven’t had that experience.

    This is the Best BBQ Sauce I’ve Ever Tasted! Made this for your Keto BBQ Chicken Casserole & everyone loved it, this sauce made the chicken casserole. I’m now making a double batch because this will be the only BBQ Sauce I ever use. Thank You Kasey for your wonderful recipes!!!

  8. 5 stars
    Love this BBQ sauce!! Great kick from the vinegar!! Great for so many uses! Definitely something I keep in the refrigerator! Thanks!

  9. Hi Kasey. I just made a double batch of your bbq sauce and it tastes amazing!! I used Truvia as that is all I had and it still tastes great! I’m hoping Truvia is still keto?? Thank you so much for all of your recipes. My family and I love them. I wish you had a cookbook to purchase.
