Barbecue chicken is one of those comfort foods that never goes out of style, and you don’t have to give it up to stay low-carb. This keto version packs in smoky flavor, tender chicken, and a sticky, tangy sauce—without the sugar crash. It’s simple enough for a weeknight and satisfying enough for a backyard cookout.
Whether you grill, bake, or air fry, you’ll get juicy chicken and a glossy glaze that tastes like the real deal.
Ingredients
Method
- Prep the chicken: Pat the chicken dry with paper towels. Dry surface = better browning. Toss with oil, salt, and pepper.
- Mix the dry rub: Combine smoked paprika, garlic powder, onion powder, ground mustard, and chili powder. Sprinkle evenly over the chicken and rub it in.
- Make the keto BBQ sauce: In a small bowl, whisk tomato paste, apple cider vinegar, sweetener, Worcestershire, a pinch of salt, and liquid smoke. Add 2–4 tablespoons broth until it’s brushable but not runny. Adjust sweetness and tang to taste.
- Choose your cooking method: Grill: Preheat to medium heat (about 375–400°F). Oil the grates.
- Oven: Preheat to 425°F. Line a sheet pan with foil and set a wire rack on top for airflow.
- Air fryer: Preheat to 380°F. Lightly grease the basket.
- Cook the chicken: Grill: Place chicken skin-side down. Grill 5–7 minutes per side, then move to indirect heat. Cook until internal temp hits 160°F, 20–25 minutes total for bone-in.
- Oven: Roast bone-in pieces 30–35 minutes (boneless thighs 18–22), until 160°F.
- Air fryer: Cook 18–22 minutes for bone-in, 14–16 for boneless, flipping halfway.
- Glaze and finish: Brush on a generous layer of keto BBQ sauce during the last 5–8 minutes of cooking. Let it set and caramelize slightly, then brush a second light coat if you like it saucy.
- Rest and serve: Pull the chicken at an internal temp of 165°F. Rest 5 minutes. Optional: warm a tablespoon of butter into remaining sauce and spoon over the top.

Keeping It Fresh
Store leftovers in an airtight container in the fridge for 3–4 days. Keep extra sauce in a separate jar so the skin stays snappy and you can re-glaze after reheating.
Reheat gently in a 325°F oven or air fryer until warm and re-crisped, about 8–12 minutes. For freezing, wrap portions tightly and freeze for up to 2 months. Thaw overnight and reheat with a fresh brush of sauce to revive the shine.
Health Benefits
- Low-carb and high-protein: You get solid protein with minimal net carbs, perfect for keto or low-carb lifestyles.
- Healthy fats: Using olive or avocado oil supports satiety and stable energy.
- No added sugar: Swapping sugar for a keto-friendly sweetener helps avoid blood sugar spikes while keeping that classic BBQ sweetness.
- Micronutrient boost: Spices like paprika and mustard bring antioxidants and flavor without calories.
Pitfalls to Watch Out For
- Hidden sugars: Many condiments, Worcestershire sauces, or “low-carb” ketchups sneak in sugar.
Read labels and choose clean options.
- Overcooking: Dry chicken kills the vibe. Track internal temperature and pull at 165°F.
- Too much sweetener: Some sugar alcohols can taste cooling or bitter. Start small and adjust.
Allulose usually caramelizes best.
- Watery sauce: Thin sauce won’t cling. Aim for a brushable, slightly thick consistency so it sets on the chicken.
- Skipping the dry rub: The rub builds flavor from the start and helps the glaze shine. Don’t skip it.
Recipe Variations
- Spicy Chipotle: Add 1–2 teaspoons chipotle in adobo (minced) to the sauce and a pinch of cayenne to the rub.
- Carolina Gold: Swap tomato paste for 2 tablespoons mustard, keep vinegar forward, and sweeten lightly for a tangy, golden glaze.
- Smoky Coffee Rub: Add 1 teaspoon finely ground coffee and 1/2 teaspoon cocoa powder to the rub for deep, smoky notes.
- Sweet Heat: Stir a dash of hot sauce into the glaze and finish with a squeeze of fresh lime.
- Herb and Garlic: Add dried thyme and oregano to the rub; finish with chopped fresh parsley for brightness.
- Breasts Instead of Thighs: Use boneless, skinless breasts; cook to 160°F, glaze, and rest to 165°F to keep them juicy.
FAQ
Can I use a store-bought keto barbecue sauce?
Yes.
Look for a sauce with 2–3 grams net carbs or less per serving and no added sugar. Taste it first and adjust seasoning—sometimes store-bought sauces need an extra splash of vinegar or a pinch of smoked paprika.
What’s the best sweetener for keto BBQ sauce?
Allulose is ideal because it browns and tastes closest to sugar. Erythritol works but can crystallize.
A blend of allulose and monk fruit balances sweetness with a clean finish.
Do I need liquid smoke?
No, but it helps when you’re not grilling. A few drops add a smoky backbone. If you’re sensitive to it, use smoked paprika and a touch more Worcestershire.
How do I keep the chicken skin crisp?
Start with dry chicken, use a hot oven or grill, and apply the sauce only near the end.
Sauce too early and it will steam the skin instead of crisping it.
Is this recipe dairy-free?
Yes, as long as you skip the optional butter at the end. The sauce and rub are naturally dairy-free.
What sides go well and stay keto?
Try cauliflower “potato” salad, grilled zucchini, creamy coleslaw (with keto mayo), or charred broccoli. Keep sauces sugar-free to stay on track.
Can I make it in a slow cooker?
You can cook the chicken in a slow cooker on low for 4–5 hours, then transfer to a broiler or air fryer to crisp and glaze.
Brush with sauce and broil for a few minutes to set.
