Whether you’re making it as a marinade, to baste, or to dip into, my sugar free version is a great alternative to the options you’ll find in the grocery store which are laden with sugar and high fructose corn syrup, not to mention unpronounceable preservatives.

Key Ingredients

Ingredients to make a Keto or sugar free barbecue sauce.

Tomato Paste – This will serve as the base for this recipe.
Apple Cider Vinegar – I recommend using a raw and unfiltered organic version with the mother for its health benefits.
Molasses – A dark, viscous liquid with a warm and sweet flavor, find it in the baking aisle.
Brown Sugar Substitute – To make this recipe keto and sugar-free, I use a Swerve Brown. You could also use monk fruit sweetener, or straight up stevia (see tips).
Ground Mustard – Adds to the tang of the sauce. If you don’t have ground, use 1 tablespoon of prepared yellow mustard.
Worcestershire – This strong, tangy condiment will add a nice bite and zesty flavor.
Liquid Smoke – Liquid smoke gives all the smokiness and flavor of the grill! A little goes a long way, so don’t use a heavy hand. If you need to substitute, try using smoked paprika. If you like a kick to your sauce in addition to the smokiness, you can use chipotle powder.

Allspice – A single seasoning with all the flavors of nutmeg, cinnamon, and clove.
Water– just mentioning this as it’s not pictured because I’m pretty sure you already have it, but this is what will give you consistency of the sauce. 😉

A little salt and pepper to taste, and you have a rockstar sauce that’ll heighten any barbecue dish in less than 30 minutes! This recipe is incredibly simple to make and healthier than what you’d get off the shelf. It’s smoky, sweet, and tangy with just the right level of heat.

Expert Tips

Skip chemical sweeteners! – I recommend using Stevia-based sweeteners. For this recipe, I like the Swerve Brown the best. Another one that works is monk fruit sweetener, and I’ve also used straight up Stevia. If you use straight stevia, start out with 1/16 or 1/8 of a teaspoon. Some brands of Stevia have a bitter aftertaste, the best one out there is by Trim Healthy Mama and it tastes great!
Make it your own – There are certainly other flavors that you can add to this sauce– garlic, cumin, or red pepper to name a few. The best part of cooking is that you get to create what suits you.
Reduce for a delicious glaze – If you want to make this recipe into a glaze, continue carefully boiling it down until you have a nice, thick glaze that can be applied directly to meat.
Short cut! I like to simmer the sauce for ultimate flavor, but you honestly don’t need to cook this at all. You can just whisk it together and it’s good to go. If you’re going to use it in a recipe that’s going to be cooked anyway, like my BBQ Crockpot Meatballs, then definitley don’t cook it.
Thicker or thinner sauce- If you like a really thick sauce, then use less water than the recipe calls for, start with 1/4 cup instead of the 1/2 cup. If you like it thinner, then add more water. Start with 3/4 cup instead of the 1/2 cup.

Frequently Asked Questions

What ingredients are usually found in BBQ sauce?

You’ll almost always find vinegar and tomato paste in BBQ. Seasonings and spices vary per recipe, but you’ll usually see mustard and black pepper. And all recipes contain a sweetener as well, such as sugar or molasses. If you’re going for a sugar-free barbecue sauce, use molasses and a brown sugar substitute.

How long does it take to make your own BBQ sauce at home?

Not long at all! After 5 minutes of prep time and 15 minutes of cook time, you’ll have 1 ½ cups of sweet, savory barbecue sauce in less than 30 minutes.

How do you thicken BBQ sauce on keto?

The easiest way is to cut back on the amount of water in the recipe. Other thickeners that you could use that are keto-friendly are xantham gum or glucomannan powder. Arrowroot powder could also be used. Be careful with glucomannan, if you use too much it can make your sauce slimy.

Storing and Freezing

My low carb BBQ sauce will last 1-2 weeks in the refrigerator and must be refrigerated at all times. Store in an airtight container or a mason jar.
This recipe is great to make in bulk if you’re a barbecue lover! If you’re planning on freezing a large batch, let it cool completely first. Frozen, it will last around 3 months. Once you’re ready to use it, move the container to the refrigerator overnight to defrost.
I would not recommend refreezing after thawing: instead, try storing your barbecue in several smaller containers so you’re only thawing as much as you need! Zip lock freezer bags work great! Freeze them flat and they thaw much quicker.
