Preheat your oven to 450°F. Pound the chicken breasts until they are of even thickness.
In a small bowl combine the salt, pepper, smoked paprika, and garlic powder. Rub both sides of the chicken breasts with the mixture.
Coat the seasoned chicken breast with the barbecue sauce, drizzle with the olive oil, then place it in a baking dish.
Bake the chicken breast in the preheated oven for 12–15 minutes.
Remove the baking dish from the oven. Let the chicken rest for 5 minutes before slicing and serving. Serve the baked BBQ chicken breasts with additional barbecue sauce on the side. Enjoy!
