Ingredients

Instructions

  1. Step 1: In a large bowl, combine 2 tbsp olive oil, 2 tbsp Kansas City BBQ rub, 1 tsp smoked paprika, 1 tsp garlic powder, 1 tbsp brown sugar, 1 tsp salt, and 1/2 tsp black pepper. Add 6 bone-in chicken thighs and toss well to coat evenly. Cover and refrigerate for at least 2 hours or overnight for best flavor.
  2. Step 2: Preheat grill to medium-high heat (about 400°F). Place the marinated chicken thighs skin-side down on the grill and cook for 6-7 minutes until the skin is crisp and grill marks appear.
  3. Step 3: Flip the chicken and continue grilling for another 6-8 minutes, or until an internal temperature of 165°F is reached and juices run clear.
  4. Step 4: While chicken grills, whisk together 1/3 cup yellow mustard, 2 tbsp apple cider vinegar, 1 tbsp honey, 1 tsp Worcestershire sauce, and a few dashes of hot sauce in a small bowl until smooth and tangy.
  5. Step 5: Remove chicken from grill and let rest for 5 minutes. Serve warm with the tangy mustard sauce on the side for dipping.
