Sweet & Tangy Barbecue Sauce: Sugar Free, Low Carb, Gluten Free, Grain Free

Super quick post for a super EASY recipe! I’ve been meaning to try my hand at homemade BBQ sauce for a long time, and this recipe proves that I won’t need to buy bottled sauces anymore. The lowest carb BBQ sauce I could find in the store was a toss-up between Stubb’s and Dinosaur–both of which contain 7g of carbs per 2 tablespoon serving. Sweeter brands like KC Masterpiece have upwards of 15g of carbs per serving. Yikes! This sauce, which takes about 15 minutes total to make, has all of that sweet, tangy, smoky flavor with just 30 calories and 3g of carbs per 2 oz. serving. For those of you who are counting, that’s a 4 tablespoon serving– twice the serving of bottled sauces!

Can you say yum?! The cool thing about this sauce is that it’s totally customizable. Want it to be sweeter? Add a little more sugar substitute. Spicier? Add more hot sauce or red pepper. Less sweet? Cut down on the sweetener. No matter which way you look at it, it’s delicious!

Barbecue Sauce


  • 3/4 C low sugar ketchup (I used Heinz Low Sugar– it’s 1g/carbs per 2 T)
  • 1/2 C pureed tomatoes (I used canned diced tomatoes pureed in the food processor)
  • 2 T Worcestershire sauce (check labels– some brands contain HFCS!)
  • 1 1/2 T rendered nitrate-free bacon fat
  • 1 T hot sauce (or more if you like it spicy)
  • 1 1/2 T natural yellow mustard
  • 1/2 C apple cider vinegar
  • 1/3 C Swerve  (or sweetener of choice–add more if you like it really sweet)
  • 1 T raw honey (or honey substitute–optional)
  • 3/4 tsp. garlic powder
  • 3/4 tsp. dried onion flakes (or 1/2 tsp. onion powder)
  • 1/8 tsp. red pepper flakes
  • 3/4 tsp. chili powder
  • 1/4 tsp. salt
  • 1/4 tsp. ground black pepper


1. Combine all ingredients at once in a large sauce pan and whisk until well mixed.

2. Heat over low-medium heat until simmering. Allow to simmer about five minutes. Make sure bacon
fat has completely melted and the sauce is completely uniform in color with no lumps.

3. Pour hot mixture into a lidded container. Allow to cool, then slather your favorite meat
in this delicious sauce!

Recipe makes approx. 12 oz. of sauce.

It takes a lot of trial and error to find the "right" fit for a low carb recipe. I have made some ... different low carb desserts. You don't need to go through that! I made a list of my favorite ingredients as well as what stores you can find them at. Enjoy!

Eating healthy, for me, is about more than weight loss like it used to be. It’s about controlling my blood sugar levels and obtaining normal–or relatively normal–hormone levels. I still struggle to lose weight efficiently, but eating a wheat, sugar and gluten free diet helps to control some of the problems I’ve encountered with these health issues of mine.
