Preheat the oven to 400°F. Line a baking sheet with parchment paper or foil for easy cleanup.
In a small bowl, whisk together the barbecue sauce, olive oil, apple cider vinegar, smoked paprika, garlic powder, onion powder, black pepper, and salt until well combined.
Place the chicken thighs in a large mixing bowl. Pour the barbecue sauce mixture over the chicken, ensuring each piece is evenly coated. Let it marinate at room temperature for 10 minutes.
Arrange the chicken thighs in a single layer on the prepared baking sheet. Brush any remaining sauce from the bowl over the chicken.
Bake in the preheated oven for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F and the edges are caramelized.
Remove the chicken from the oven and let it rest for 5 minutes before serving. Serve with additional barbecue sauce on the side if desired.
