Mustard BBQ Sauce

Mustard BBQ sauce is my favorite low carb BBQ sauce recipe! It’s simple to throw together and it is positively delicious served over pulled pork or grilled chicken.

My husband bought me a smoker for my birthday a couple years ago.

Partially because I clearly enjoy cooking and trying out new things, but partially because the man is downright obsessed with pulled pork.

He piles low carb pulled pork on his plate, tops it off with some keto coleslaw, and goes to town .

We’ve purchased the low carb bbq sauce in a bottle from the local grocery store and it’s pretty good, but I knew I could do better at home and that’s exactly what I did.

I’m still perfecting my traditional sugar free bbq sauce, but this mustard bbq sauce? Nailed it!

Mustard Based BBQ Sauce:

If you’ve never had a mustard BBQ sauce before, you’re in for a treat!

Traditionally, barbecue sauce starts with ketchup or tomatoes and a whole lot of sugar. Tomatoes are already fairly carb-y and then adding all that sugar just makes traditional BBQ sauce totally not low carb friendly.

Starting with mustard solves that problem nicely and makes for a really unique, boldly flavored, tangy, semi-sweet sauce. The flavors all just explode in your mouth!

Word of warning: If you don’t like mustard, you will probably hate this sauce. Just throwing that out there, because I know I’ll get emails asking if you can ‘taste the mustard.’ You can definitely taste the mustard. 😉

Yellow Mustard – We’re using a bottle of traditional, American-style yellow mustard. The kind you’d put on a hot dog.

Apple Cider Vinegar – Vinegar will add that perfect tangy taste to the sauce!

Sweetener – For this low carb barbecue sauce, I’m using my favorite brown sugar substitute: Lakanto Monkfruit Sweetener. To me, it tastes just as good as brown sugar! No weird aftertaste or cooling effect and 0 net carbs. Use code THATLOWCARBLIFE for 20% off your order at Lakanto!

Molasses – Just about any good BBQ sauce has some molasses in it. It really adds a lot of flavor! Just be sure to use regular molasses and not the blackstrap molasses.

Cayenne Pepper – This will add a little heat to the sauce! If you want to increase the spiciness, just add more!

Why We Love This Recipe:

This sauce has a tangy, vibrant flavor that pairs really well with pulled pork. Plus, it’s beyond easy – just toss in a sauce pan, stir, and cook. It’s easy to adjust the sweetness, heat, and tang for this recipe too, which makes it a favorite with readers.

How To:

  • Mix – This is a mustard based BBQ sauce, so we’ll start with an entire cup of yellow mustard. I’m just using ballpark style American yellow mustard. You’ll also add in some chicken stock, apple cider vinegar, your favorite sugar substitute, a spoonful of molasses, Worcestershire sauce, and the seasonings. Basically just fill up a pot on the stove with all the ingredients. Simple!Spoon dripping sauce into a jar
  • Heat & Eat – Bring your pot of ingredients to a boil, reduce to a simmer, and cook for about 5-10 minutes. You want the sauce to reduce a bit and thicken up. Give it a taste and add more salt, pepper, or cayenne, depending on your preferences. That’s all there is to it! The sauce may thicken a little more as it cools. All that’s left to do is pour it over something tasty like pulled pork!

Generally most brands of mustard are going to be low carb! But some will sneak in sweeteners so just check the label if you aren’t sure. Otherwise, use your favorite brand!

    I’m in South Carolina, so “mustard based bbq sauce” is just bbq sauce to me, and your recipe is fantastic! Thank you, thank you, thank you! I have made it about 20 times in the past year, and tonight my SO asked me where if I came up with it myself. I told him about your blog and he suggested that I thank you, making me realize a “thank you” to you is way over due! Thank you, sincerely. Your blog has been a blessing to me and my family.

    1. Karly Campbell

      Thanks for the sweet comment, Kelly! I’m so glad you enjoy the recipe and have found the website helpful! ๐Ÿ™‚

    The nutrition card says 16 servings. The serving size says 1. 1 what, oz, gram, tsp, tbsp? If I eat the whole thing, I’ll eat 238 calories and 32 net carbs!
    Please clarify.
    Thanks.

    1. Karly Campbell

      Each serving should be about 2 tablespoons, but it’ll depend on how much you reduce the sauce.

  3. Erin Wright

    This is really sweet as the recipe stands. What would you recommend to balance it out?

  4. This sauce was excellent! Used it on the side to dip pilled pork in, perfectly tangy and a little went a long way.

  5. I’m wondering if i can omit the molasses (dont keep any in the house) and sub the erythritol with the Swerve brown sugar for a similar flavor?

  6. This stuff is really good! After tasting, I added a quarter or half teaspoon of white pepper (eye-balled it) and a teaspoon of tarragon to deepen the flavor a bit. I do think that adds to it, but it’s fantastic as written.

      The nutrition info is in the recipe card. If you need more detailed information, you can enter the recipe into a nutrition calculator. ๐Ÿ™‚

  7. This looks awesome and i’m excited to try it, but I am curious why you specify to NOT use blackstrap molasses?

  8. Could I possibly use Yacon syrup instead of molasses? Just trying to use what I already have in my kitchen.

    1. Karly Campbell

      I haven’t tried Yacon syrup before. If it’s very sweet, you might just reduce the sweetener a bit. It should work fine though!

  9. Made this today using the juices from the crockpot… omitted the sweetener & molasses, just because sweetener seems to do funny things to my body & stalls my ketosis. Nice tangy mustard! Perfect with the pork. Thank you!

  10. This is delicious!! Thank you. I am not even sure what I will serve it with yet, but I love mustard and made it as soon as I saw the recipe.

  11. Bec (It's Yummi)

    This mustard BBQ sauce is so good, Karly! I served it with Cajun smoked spare ribs and my husband devoured them!

  12. Perfect, Karly! I can’t wait to make this.

    By the way, my husband loved the radishes, I thought they were great too, but I kept wanting them to taste like potatoes, even though I knew they wouldn’t/couldn’t.

    Can someone please make a potato without carbs, please Lord!!!
    Keep these recipes coming, they are always a hit with us! Even though, I had to take your pancake cookbook to the basement, too hard to look at ๐Ÿ™‚
