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. A little sweet, a little tangy, and so easy!
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.
We’ve always 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. 😉
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.

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.
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!
We use Thrive Market for a lot of our specialty ingredients and keto snacks or products. Their prices tend to be cheaper than the local stores and I love that you can so easily sort products by diet.
Like Costco, this is a membership site, but we find that it’s more than worth it based on the amount we save over the regular grocery store.
They have monthly or yearly plans. Check it out here.
- 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 (or the liquid from cooking a pulled pork), 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!
- Heat – 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!
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. – Joan
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.
Yes! It is a mustard based sauce, so if you don’t like mustard this probably isn’t for you. There are definitely some other great flavors in it though that come from the vinegar, molasses, Worcestershire, and seasonings.
Yep, it’ll store well in a sealed mason jar in the refrigerator for up to a week! We have not tried canning this recipe and don’t know if it would be safe to do so.
