Skip the sugar-loaded bottles and make a barbecue sauce that actually fits your goals. This keto barbecue sauce is smoky, tangy, a little spicy, and easy to whip up with pantry staples. It clings to chicken, ribs, and grilled veggies just like the classic version.
Best of all, you control the sweetness and heat. If you’ve been missing BBQ on a low-carb lifestyle, this one brings it back without compromise.
Ingredients
Method
- Combine the base: In a small saucepan, whisk together tomato paste, apple cider vinegar, and 1 cup of water or broth until smooth.
- Season it: Add 2–3 tablespoons keto sweetener, 1 tablespoon Worcestershire, 1 tablespoon yellow mustard, 1–2 teaspoons smoked paprika, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1/2 teaspoon black pepper, and 1/2 teaspoon salt.
- Optional kick: Stir in a pinch of cayenne or 1/4 teaspoon chipotle powder if you like heat. Add 2–4 drops liquid smoke if using.
- Simmer: Bring to a gentle simmer over medium heat. Reduce heat to low and cook for 12–15 minutes, stirring occasionally, until thickened and glossy.
- Taste and adjust: Add more sweetener for sweetness, vinegar for tang, or water to thin. Salt to taste.
- Cool and serve: Let the sauce cool slightly. It will thicken as it cools. Brush on grilled meats or use as a dipping sauce.

Why This is Good for You
Low in sugar and carbs means it supports stable energy and ketosis without sacrificing flavor. You’re skipping high-fructose corn syrup and added sugars common in store-bought sauces. The tomato paste provides antioxidants like lycopene, while apple cider vinegar adds tang without calories.
Using smoked paprika and spices gives big flavor, so you rely less on sweeteners overall. It’s satisfying, bold, and easy on your macros.
Pitfalls to Watch Out For
- Hidden sugars: Check labels on tomato paste, Worcestershire, and mustard. Choose no-sugar-added options.
- Over-sweetening: Keto sweeteners can taste stronger than sugar.
Start with less and build up.
- Crystallization: Erythritol can crystallize as the sauce cools. Allulose stays smoother if that’s a concern.
- Too thick or thin: Control thickness with simmer time and small splashes of water to thin as needed.
- Liquid smoke overload: A few drops go a long way. Add gradually.
Recipe Variations
- Carolina-style (tangy): Increase apple cider vinegar, add a bit more mustard, and reduce sweetener. Great for pulled pork.
- Texas-style (peppery): Add extra black pepper, a pinch of cumin, and a little chipotle for heat and smoke.
- Smoky maple vibe: Use an allulose/monk fruit “maple” syrup substitute in place of granulated sweetener for a subtle maple note.
- Bourbon-inspired: Add 1–2 teaspoons bourbon extract for aroma without the carbs.
Keep it light.
- Coffee kick: Stir in 1–2 teaspoons strong brewed espresso for deeper complexity and bitterness to balance sweetness.
- Tomato swap: Use strained tomatoes (passata) and simmer longer for a looser, more pourable sauce.
FAQ
Is this sauce completely sugar-free?
It’s free of added sugar when you choose sugar-free ingredients. Tomatoes have a small amount of natural sugar, but the overall carbs are still very low per serving.
What’s the best sweetener to use?
Allulose gives the smoothest texture and least aftertaste. A monk fruit–erythritol blend also works, but it may crystallize slightly after chilling.
Adjust to taste.
Can I use tomato sauce instead of tomato paste?
Yes, but you’ll need to simmer longer to reduce and concentrate the flavor. Start with less water and adjust as it cooks down.
How spicy is this recipe?
Mild by default. For more heat, add cayenne, chipotle, or a splash of hot sauce.
Taste as you go to avoid overdoing it.
Can I use this as a marinade?
Yes, but because it’s thicker and contains acids, marinate for no more than 2–4 hours for chicken or pork. Wipe off excess before grilling to prevent burning.
Will it burn on the grill?
It can if applied too early or over high flame. Brush it on during the last 5–10 minutes of cooking and keep heat moderate for a glossy finish without scorching.
How many carbs per serving?
It typically comes out to about 1–2 net carbs per 2 tablespoons, depending on your ingredients and sweetener.
Always check your labels and calculate if you track closely.
Can I make it in advance?
Absolutely. The flavor gets even better after a day in the fridge. Store it in a sealed jar and give it a quick stir before using.
What can I serve it with?
Grilled chicken thighs, pulled pork, brisket, smoked turkey, bunless burgers, roasted cauliflower, or zucchini fries.
It’s also great as a dip with keto chicken tenders.
How do I thin it for a glaze?
Add a tablespoon or two of water or broth at a time and whisk over low heat until it reaches your desired consistency.
