Gluten Free Sugar Free BBQ Sauce Recipe: Tangy Smoke Without the Sugar

This sauce delivers the deep, smoky flavor of traditional barbecue without the glucose spike. I developed it after years of searching for a condiment that satisfied both my pitmaster standards and dietary needs.

Thick, tangy, and perfectly balanced, it clings to ribs or brushes onto chicken with restaurant-quality results. Store in the fridge for up to two weeks—if it lasts that long.

Tomato paste is the base here, so look for no-sugar-added brands like Muir Glen or Hunt’s Natural. The vinegar should be raw—Bragg’s is my go-to (the cloudy stuff with the mother). Smoked paprika is doing heavy lifting, so don’t skimp. Penzeys has great quality, but most grocery store brands work. Liquid smoke can be polarizing, but Wright’s hickory-flavored is the most balanced I’ve found.

No erythritol? Monk fruit sweetener at 1:1 ratio works the same. Swap blackstrap molasses for unsulphured regular molasses if that’s what you have (but cut the amount by half—it’s sweeter). No vegan Worcestershire? Coconut aminos plus a dash of tamari gets you close. The garlic and onion powder can be fresh minced at 3 cloves and 1 small onion, sautéed first. Just adjust thickness with water.

This keeps 2 weeks in the fridge—if you can resist using it all first. Freeze in ice cube trays for 6 months (thaw overnight in the fridge). The flavor actually deepens after a day or two, so make it ahead if you can (worth the extra minute).

Step-by-Step Instructions for Sugar Free BBQ Sauce

This method delivers bold smoky flavor with perfect balance—sweet, tangy, and rich without sugar.

Step 1: Combine Wet Base Ingredients

In a medium saucepan, whisk together the 1 cup Tomato Paste, 0.5 cup Apple Cider Vinegar, and 0.5 cup Water until smooth. The tomato paste should fully dissolve into the liquid with no lumps remaining.

Place the saucepan over medium heat and bring to a gentle simmer. This initial heating helps meld the base flavors together before adding the spices. You’ll notice the mixture darken slightly and thicken as it warms.

Step 2: Incorporate Spices and Flavorings

Add the 2 tbsp Smoked Paprika, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, and 1 tsp Liquid Smoke to the simmering mixture. Stir constantly for 1-2 minutes to prevent sticking and ensure even distribution of the spices.

The smoked paprika will deepen the color to a rich reddish-brown, while the liquid smoke adds that authentic barbecue aroma. The mixture should become fragrant as the spices bloom in the heat.

Step 3: Sweeten and Finish the Sauce

Stir in the 0.33 cup Erythritol, 1 tbsp Blackstrap Molasses, and 1 tbsp Worcestershire Sauce. The erythritol should dissolve completely, and the molasses will add a deep, caramel-like color and subtle bittersweet complexity.

Reduce heat to low and let the sauce simmer for 10-15 minutes, stirring occasionally. The sauce should thicken enough to coat the back of a spoon but still be pourable. Taste and adjust seasoning if needed, though the flavors will intensify as it cools.

Step 4: Cool and Store for Optimal Flavor

Remove the saucepan from heat and let the BBQ sauce cool to room temperature. The flavors will continue to develop as it cools, with the spices mellowing and the smoke becoming more pronounced.

Once cooled, transfer to an airtight container. The sauce will keep in the refrigerator for up to 2 weeks. For the best texture and flavor, I recommend letting it sit for at least 24 hours before using to allow all the elements to fully marry.

Dietary Considerations for This gluten free sugar free bbq sauce

Gluten-Free Assurance

This sauce is naturally gluten-free as written, with no wheat, barley, or rye ingredients. The only potential concern is the Worcestershire sauce—always verify the label. I use Annie’s Vegan Worcestershire which is certified gluten-free and adds that essential umami depth. 💪

Sugar-Free Sweetness

The erythritol provides sweetness without spiking blood sugar, making it ideal for keto and diabetic diets. For a more natural option, swap in monk fruit sweetener at the same ratio. The blackstrap molasses adds minerals like iron and calcium while contributing minimal sugar.

Vegan-Friendly Base

All ingredients are plant-based, from the tomato paste to the vinegar. The only adjustment needed is ensuring your Worcestershire sauce is vegan. Edward & Sons makes a great vegan version that doesn’t compromise on flavor.

Allergen Considerations

This recipe is free from the top 8 allergens, including dairy, eggs, and nuts. The only possible allergen is sulfites in some molasses brands. I recommend Wholesome Sweeteners Organic Blackstrap Molasses which is unsulphured.

Low-Carb Benefits

With only 4g net carbs per 2-tbsp serving, this sauce fits perfectly into low-carb and keto lifestyles. The erythritol doesn’t impact blood sugar, and the molasses contributes just 1g sugar per serving. Perfect for keeping your macros in check. ✨

Nutritional Highlights

Each serving provides a boost of lycopene from the tomato paste and acetic acid from the apple cider vinegar. The spices like smoked paprika also contribute antioxidants. It’s a flavorful way to add nutrition to your meals.
