• Step 1: Preheat your oven to 375°F (190°C). Line a large baking sheet with foil or parchment paper for easy cleanup.
• Step 2: In a small bowl, whisk together the barbecue sauce, brown sugar, smoked paprika, garlic powder, and cayenne pepper (if using). Season the chicken thighs with salt and pepper.
• Step 3: Arrange the chicken thighs on the prepared baking sheet and brush them generously with the barbecue sauce mixture, making sure to coat all sides.
• Step 4: Bake the chicken for 35-40 minutes, basting with the sauce every 10-15 minutes, until the chicken is cooked through and the sauce is caramelized.
• Step 5: Remove the chicken from the oven and let it rest for 5 minutes before serving. Enjoy your delicious oven-baked barbecue chicken!
