Preheat the oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish.

Rub each chicken breast with olive oil, then place in the prepared dish. Season with garlic powder, salt, and pepper. Pour Worcestershire sauce over each breast. Cover the dish with aluminum foil.

Bake in the preheated oven until chicken is no longer pink at the bone and the juices run clear, 45 to 60 minutes. An instant-read thermometer inserted near the bone should read at least 165 degrees F (74 degrees C).
