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 5 minutes. Stir in 2 minced garlic cloves and cook for another minute until fragrant, filling your kitchen with aromatic goodness. This forms the flavorful base of the spicy BBQ sauce that will elevate your grilled chicken thighs.
Step 2: Mix the Sauce Ingredients
To the onions and garlic, add ¼ cup of apple cider vinegar, ½ cup of water, and ¾ cup of ketchup. Stir in 1 teaspoon of paprika, 2 tablespoons of sriracha, 1 tablespoon of sambal oelek (or more sriracha for milder heat), 1 teaspoon of chili powder, 1 tablespoon of mustard, and 1 tablespoon of Worcestershire sauce. Let this mixture simmer over low heat for 15 minutes, until thickened, stirring occasionally to combine the flavors beautifully.
Step 3: Season the Chicken
While the BBQ sauce simmers, prep 4 boneless, skinless chicken thighs by patting them dry with paper towels. Drizzle 1 tablespoon of olive oil over the thighs and season generously with salt and black pepper, ensuring every nook and cranny is coated. This seasoning not only enhances flavor but also helps the chicken develop a lovely crust on the grill.
Step 4: Preheat the Grill
Preheat your grill to medium-low heat (around 300°F to 325°F). This temperature ensures that the chicken cooks evenly without drying out. Once heated, lightly oil the grill grates to prevent sticking. You’ll be ready to grill the chicken thighs when you see a few wisps of smoke rising from the grill, signaling it’s at the right temperature.
Step 5: Grill the Chicken Thighs
Place the seasoned chicken thighs on the grill skin-side down. Cook them on low heat, flipping every 3-4 minutes to prevent burning. Keep an eye on the chicken until the juices run clear and an instant-read thermometer registers 165-170°F, which should take about 20 minutes. The beautiful char marks and golden edges indicate they’re perfectly grilled.
Step 6: Baste with BBQ Sauce
During the last few flips, generously baste the grilled spicy BBQ chicken thighs with the prepared sauce, ensuring every piece is coated in that delicious mixture. This not only adds flavor but also creates a sticky glaze as it caramelizes on the grill. Be sure to save some sauce for serving, as this will enhance your chicken even further!
Step 7: Rest and Serve
Once the chicken is cooked through and beautifully glazed, remove it from the grill and let it rest on a plate for about 5 minutes. This resting period allows the juices to redistribute, enhancing the juiciness. Serve these scrumptious Grilled Spicy BBQ Chicken Thighs with the reserved BBQ sauce and your favorite summer sides for a complete and satisfying meal.

How to Store and Freeze Grilled Spicy BBQ Chicken Thighs
