Sugar-Free BBQ Sauce — The Grilling Swap
BBQ sauce is one of those things I assumed was mostly smoke and spice. It is not. Most store-bought versions contain 16g of sugar per two tablespoons — that is four teaspoons before you've even sat down at the table.
This version is properly smoky, properly thick, and genuinely satisfying in the way that good BBQ sauce should be. The secret is brown allulose, which caramelises beautifully and gives you that rich, deep colour without the sugar hit. Liquid smoke does the rest of the heavy lifting.
Brush it on chicken, ribs, pulled pork — or honestly just eat it with a spoon and call it research. I won't judge.

Ingredients
Makes about 2 cups · 16 servings (2 tbsp each)
- 1 can (425g / 15 oz) tomato sauce
- ¼ cup tomato paste
- ½ cup apple cider vinegar
- ½ cup ⇄ brown allulose — the sweetener swap
- 1 tbsp liquid smoke (mesquite flavour)
- 1 tbsp Worcestershire sauce (sugar-free if possible)
- 1 tsp smoked paprika
- 1 tsp garlic powder
- ½ tsp black pepper
Instructions
- 1
Combine all ingredients in a medium saucepan over medium heat and stir well.
- 2
Bring to a gentle simmer, stirring frequently to prevent sticking.
⇄ Swap NoteBrown allulose behaves like brown sugar during cooking — it melts and caramelises properly. You'll see the sauce darken and thicken as it simmers, just like the real thing.
- 3
Reduce heat to low and simmer for 15–20 minutes, stirring occasionally, until the sauce thickens and the flavours deepen.
- 4
Let cool before using as a glaze or dipping sauce. It thickens further as it cools.
The Secret to Smoky Flavour Without Molasses
Traditional BBQ sauce gets its colour and sweetness from molasses and brown sugar — both high in added sugar. The good news is that flavour comes from the combination of smoke, acid, and caramelisation — none of which actually requires sugar. Liquid smoke handles the depth, apple cider vinegar handles the tang, and brown allulose handles the caramelisation.

Common Mistakes
- Using too much liquid smoke. It's very concentrated — one tablespoon is exactly right. More than that and the sauce becomes medicinal.
- Rushing the simmer. The 20 minutes is what transforms this from a collection of ingredients into a proper sauce. Don't skip it.
- Using standard Worcestershire. Most Worcestershire sauces contain added sugar. Check the label or use a sugar-free version — it makes a difference.
Storage
Store in a sealed glass jar in the fridge for up to 3 weeks. The flavour deepens over time — it's always better on day two. Freezes well in an ice cube tray for portion-controlled cooking.

Frequently Asked Questions
Can I use monk fruit instead of brown allulose?
You can, but the sauce won't have the same deep colour or caramelised texture. Brown allulose is specifically good for BBQ because it behaves like brown sugar in the pan. Check the Swap Guide for more on when to use which sweetener.
Where do I find liquid smoke?
Most large supermarkets stock it in the condiments aisle. Online is also easy. Mesquite or hickory both work well here.
Can I use this as a marinade?
Yes — it makes an excellent marinade. Use it on chicken, ribs, or pulled pork and leave for at least 2 hours before cooking.
