Step‑by‑Step Instructions for Grilled Spicy BBQ Chicken Thighs
Step 1: Prepare the BBQ Sauce
In a medium saucepan over medium heat, melt 2 tablespoons of butter. Add 1 finely chopped yellow onion and sauté until softened, about 3-4 minutes. Stir in 2 cloves of minced garlic, cooking until fragrant. Then, combine ¼ cup of apple cider vinegar, ½ cup of water, 1 cup of ketchup, and the remaining spices. Simmer for approximately 15 minutes until the sauce thickens, stirring occasionally, then remove from heat.
Step 2: Season Chicken
While the BBQ sauce simmers, take 2 pounds of boneless skinless chicken thighs and pat them dry with paper towels. Rub each thigh generously with olive oil, followed by salt and black pepper to taste, ensuring an even coating. This seasoning will enhance the flavor of your Grilled Spicy BBQ Chicken Thighs, creating a deliciously savory base as they grill.
Step 3: Grill Chicken
Preheat your grill to medium-low heat, aiming for about 300°F (150°C). Once hot, place the seasoned chicken thighs skin-side down on the grill. Cook for 6-7 minutes, flipping them every 3-4 minutes to achieve an even golden-brown char. Grill until the internal temperature reaches 165-170°F (75-77°C) and the juices run clear, indicating they are perfectly cooked.
Step 4: Baste Chicken
During the last few minutes of grilling, use a brush to generously baste the juicy chicken thighs with the spicy BBQ sauce you prepared earlier. This step adds an extra layer of flavor to your Grilled Spicy BBQ Chicken Thighs, creating a glossy, caramelized finish. Keep an eye on them to prevent burning, and turn them once more to allow the sauce to settle while grilling.
Step 5: Rest and Serve
Once fully cooked and beautifully glazed, transfer the chicken thighs to a plate and let them rest for about 5 minutes. This resting period allows the juices to redistribute, making every bite even more tender. Serve the grilled spicy BBQ chicken thighs with your favorite sides, and relish the delicious flavors enhanced by the zesty sauce!

Make Ahead Options
These Grilled Spicy BBQ Chicken Thighs are perfect for busy weeknights or meal prepping!
