What makes this recipe absolutely extraordinary is how it delivers every bit of that smoky, sweet, tangy BBQ experience while being completely keto-friendly and low-carb, proving that eating healthy doesn’t mean sacrificing the flavors you love most. I created this when I was following a low-carb lifestyle but desperately missing barbecue chicken, and it’s become such a game-changer that even my carb-loving friends request this over traditional BBQ because the flavors are so much more intense and the chicken stays incredibly juicy from the one-skillet cooking method. The secret is the homemade sugar-free BBQ sauce that tastes even better than store-bought versions, plus the technique of cooking everything together so the vegetables absorb all those amazing BBQ flavors while the chicken develops the most incredible caramelized crust.
Why This Low Carb BBQ Chicken Thighs Skillet Actually Works
The brilliance of this recipe lies in using chicken thighs, which are naturally more flavorful and stay incredibly juicy even with longer cooking times, paired with a homemade BBQ sauce that gets its sweetness from natural sugar alternatives that caramelize beautifully without adding carbs. The one-skillet method allows the chicken to develop a gorgeous seared crust while the vegetables cook in all those delicious drippings, creating layers of flavor that you simply can’t achieve with separate cooking methods.
What makes this BBQ sauce so special is the careful balance of tomato paste, apple cider vinegar, and spices with sugar-free sweeteners that provide that essential sweet-tangy contrast without any blood sugar spikes. The sauce reduces and concentrates during cooking, creating that thick, glossy coating that clings to the chicken perfectly. The vegetables not only add nutrition and fiber but also absorb the BBQ flavors, making every bite of this one-pan meal absolutely delicious and satisfying.

Complete Ingredients Breakdown
For the Chicken:
2½ Pounds Bone-In, Skin-On Chicken Thighs Chicken thighs are essential for this recipe because they stay incredibly juicy during the longer cooking time needed to develop the BBQ flavors. Choose thighs that are plump and meaty with good skin coverage. The bone and skin add flavor and help keep the meat moist. Avoid boneless thighs, which can dry out more easily.
2 Tablespoons Olive Oil Use regular olive oil rather than extra virgin since you’ll be cooking at medium-high heat. The oil helps the chicken skin get crispy and golden while preventing sticking. You can also use avocado oil, which has a higher smoke point.
2 Teaspoons Smoked Paprika Smoked paprika is crucial for authentic BBQ flavor – it adds that essential smokiness that makes this taste like it came off an actual grill. Hungarian smoked paprika is particularly good if you can find it. The paprika should smell intensely smoky and sweet.
1 Teaspoon Garlic Powder Garlic powder distributes more evenly than fresh garlic when used as a dry rub and won’t burn during the searing process. It should smell strongly of garlic and be free of lumps. This adds savory depth that complements the BBQ flavors perfectly.
1 Teaspoon Onion Powder Onion powder adds sweet, savory depth that enhances the overall flavor profile. Like garlic powder, it should smell strongly aromatic and have a fine, uniform texture. This helps build that complex BBQ taste.
1 Teaspoon Salt Use kosher salt or coarse sea salt for the best flavor and texture. Generous seasoning is important for chicken thighs, which can handle bold flavors. The salt also helps draw out moisture for better browning.
½ Teaspoon Black Pepper Freshly ground black pepper adds warmth and complexity. Use enough to provide noticeable pepper flavor that enhances the smoky BBQ profile without overpowering the other spices.
For the Sugar-Free BBQ Sauce:
¼ Cup Tomato Paste Tomato paste provides the rich, concentrated tomato base that’s essential for authentic BBQ sauce flavor. Choose high-quality tomato paste that’s thick and deeply colored. This adds umami depth and natural richness without added sugars.
¼ Cup Apple Cider Vinegar Apple cider vinegar provides the essential tangy acidity that balances the sweetness and cuts through the rich chicken. Use raw, unfiltered apple cider vinegar for the most complex flavor. This is crucial for authentic BBQ taste.
2 Tablespoons Sugar-Free Brown Sugar Substitute (like Lakanto or Swerve) Sugar-free brown sugar substitutes provide sweetness and caramelization without the carbs. Lakanto and Swerve brown sugar alternatives work particularly well because they caramelize similar to real brown sugar. Make sure to use brown sugar substitute, not white, for the deeper flavor.
1 Tablespoon Worcestershire Sauce Worcestershire adds complex umami depth with its blend of anchovies, molasses, and spices. Check that your brand is sugar-free or very low in sugar. This ingredient adds incredible depth that makes the sauce taste more sophisticated.
1 Teaspoon Liquid Smoke Liquid smoke provides authentic BBQ flavor that makes this taste like it was cooked over actual wood. Use it sparingly – a little goes a long way. Wright’s is a good brand that provides clean smoke flavor without chemical aftertastes.
1 Teaspoon Dijon Mustard Dijon mustard adds tangy depth and helps emulsify the sauce for smooth texture. It should be sharp and aromatic, not mild or sweet. This adds complexity that distinguishes great BBQ sauce from basic versions.
½ Teaspoon Smoked Paprika Additional smoked paprika in the sauce reinforces that essential smoky flavor throughout the dish. This ensures every bite has that authentic BBQ taste that makes this recipe so satisfying.
¼ Teaspoon Garlic Powder Garlic powder in the sauce adds savory depth that complements the fresh garlic in the vegetables. This builds layers of garlic flavor that enhance the overall taste without being overwhelming.
¼ Teaspoon Onion Powder Onion powder adds sweet, savory notes that round out the sauce flavor. Combined with the fresh onions in the vegetables, this creates complex onion flavor throughout the dish.
For the Low-Carb Vegetables:
1 Large Red Bell Pepper (cut into strips) Red bell peppers add sweetness, crunch, and beautiful color that complements the BBQ flavors perfectly. Choose peppers that are firm, bright red, and heavy for their size. Remove all seeds and white ribs before cutting into ½-inch strips.
1 Large Yellow Bell Pepper (cut into strips) Yellow peppers add different color and slightly different flavor notes than red peppers, creating visual interest and flavor complexity. They should be firm and bright yellow with no soft spots or wrinkled areas.
1 Medium Zucchini (sliced into half-moons) Zucchini is perfect for low-carb cooking because it’s very low in carbs while adding substance and nutrition. Choose firm, medium-sized zucchini with bright, unblemished skin. Cut into ½-inch half-moons for even cooking.
1 Medium Yellow Onion (sliced) Yellow onions become sweet and caramelized when cooked, adding natural sweetness that complements the BBQ sauce. Slice them into half-moons about ¼ inch thick so they cook evenly and develop good color.
3 Garlic Cloves (minced) Fresh garlic adds pungent depth that mellows during cooking and enhances all the other flavors. The cloves should be firm and aromatic, minced finely so they cook evenly and distribute throughout the vegetables.
For Garnish and Serving:
2 Tablespoons Fresh Parsley (chopped) Fresh parsley adds bright color and fresh flavor that cuts through the richness of the BBQ chicken. Choose flat-leaf parsley for the best flavor, and make sure it’s fresh and vibrant green with no wilting.
1 Tablespoon Fresh Chives (chopped) Fresh chives add mild onion flavor and beautiful color. They should be bright green and crisp, not wilted or yellowing. Cut them with sharp scissors rather than a knife to avoid bruising.
Lemon Wedges (for serving) Fresh lemon wedges add brightness and acidity that enhances the BBQ flavors and cuts through the richness. The lemons should be firm and heavy with bright yellow, unblemished skin.
Step-by-Step Instructions
1. Pat the chicken thighs completely dry with paper towels, then season generously on both sides with the smoked paprika, garlic powder, onion powder, salt, and pepper. Let them sit at room temperature for 15-20 minutes while you prepare the other ingredients. This helps the seasoning penetrate and ensures even cooking.
2. Make the BBQ sauce by whisking together tomato paste, apple cider vinegar, brown sugar substitute, Worcestershire sauce, liquid smoke, Dijon mustard, smoked paprika, garlic powder, and onion powder in a small bowl until smooth. Set aside – the sauce will be added later in the cooking process.
3. Heat olive oil in a large, oven-safe skillet (like cast iron) over medium-high heat until it shimmers. The skillet should be large enough to hold all the chicken thighs without overcrowding – work in batches if necessary.
4. Place the seasoned chicken thighs skin-side down in the hot skillet and cook for 5-6 minutes without moving them, until the skin is golden brown and crispy. You want to develop a beautiful crust that will hold up to the sauce and vegetables.
5. Flip the chicken thighs and cook for another 4-5 minutes until the second side is golden brown. The chicken doesn’t need to be completely cooked through at this point – it will finish cooking with the vegetables and sauce.
6. Remove the chicken thighs to a plate and set aside. Pour off all but 2 tablespoons of the fat from the skillet, reserving those flavorful drippings for cooking the vegetables. This keeps the dish from being too greasy while maintaining flavor.
7. Add the sliced onions to the skillet with the reserved drippings and cook for 3-4 minutes until they start to soften and caramelize. The onions should pick up all those delicious browned bits from the chicken.
8. Add the bell pepper strips and minced garlic to the onions and cook for another 2-3 minutes until the peppers start to soften slightly but still have some crunch. The vegetables should be colorful and aromatic.
9. Add the zucchini half-moons to the skillet and cook for 1-2 minutes just until they start to soften. Zucchini cooks quickly, so you want to add it last to prevent it from becoming mushy.
10. Pour the prepared BBQ sauce over the vegetables and stir gently to coat everything evenly. Let the sauce simmer for 1-2 minutes to start developing flavor and thickness.
11. Nestle the seared chicken thighs back into the skillet, skin-side up, on top of the vegetables and sauce. The skin should remain above the sauce level to stay crispy while the bottom absorbs flavors.
12. Transfer the skillet to a preheated 375°F oven and bake for 25-30 minutes until the chicken is cooked through (internal temperature of 165°F) and the sauce has thickened and caramelized around the edges.
13. Remove from the oven and let rest for 5 minutes to allow the juices to redistribute. Garnish with fresh parsley and chives, and serve with lemon wedges for extra brightness.
Pro Tips & Variations
Crispy Skin Success: The key to crispy chicken skin is starting with completely dry chicken and not moving it too early during the searing process. Let it develop a proper crust before flipping, and keep the skin above the sauce level during the final baking.
BBQ Sauce Customization: Adjust the sweetness and tanginess to your taste by varying the brown sugar substitute and vinegar amounts. For spicier BBQ, add a pinch of cayenne pepper or red pepper flakes. For smokier flavor, increase the liquid smoke slightly.
Vegetable Variations: This technique works with many low-carb vegetables. Try adding mushrooms, asparagus, Brussels sprouts, or cauliflower. Just adjust cooking times based on how long each vegetable needs to become tender.
Make-Ahead Options: You can season the chicken and make the BBQ sauce up to a day ahead. The dish can also be assembled completely and refrigerated before the final baking step, making it perfect for meal prep or entertaining.
Troubleshooting Common Issues
“My chicken skin isn’t crispy” – Make sure the chicken is completely dry before seasoning and that your skillet is hot enough before adding the chicken. Don’t move the chicken too early during searing, and keep the skin above the sauce level during baking.
“The sauce is too thick/thin” – BBQ sauce thickness can be adjusted during cooking. If too thick, add a tablespoon of water or chicken broth. If too thin, simmer it longer before adding the chicken back to the skillet.
“It’s not sweet enough” – Different sugar substitutes have varying sweetness levels. Taste the sauce before adding it to the skillet and adjust the brown sugar substitute to your preference. Remember that the sauce will concentrate as it cooks.
“The vegetables are mushy” – Add vegetables in order of cooking time needed – onions first, then peppers, then zucchini last. Don’t overcook in the initial sautéing stage since they’ll continue cooking in the oven.
“Not enough BBQ flavor” – Make sure your smoked paprika is fresh and aromatic, and don’t skip the liquid smoke which provides essential BBQ taste. You can also brush extra sauce on the chicken during the last 10 minutes of baking for more intense flavor.
