1. Line a 6-quart slow cooker with 8 to 10 forks facing up or down, arranging them in a way that keeps the chicken lifted from the bottom of the slow cooker.
2. Season the chicken with salt and pepper, rubbing into the meat. Set aside.
3. In a bowl, mix Parmesan, garlic, thyme and rosemary. Sprinkle all over chicken, pressing into the meat to create a crust.
4. Gently place chicken onto the forks in the slow cooker, bone side down.
5. Cover and cook on high for 3 hours.
6. Rest for 5 to 10 minutes with lid partially open. Serve.
