Wash and dry the chicken, then place on a roaster pan.
Coat with coconut oil.
Season the outside and inside of the chicken with sea salt, black pepper, garlic, and dried rosemary.
Add cut lemon to the inside of the chicken.
Place in the oven and roast for 1 hour. Check the thickest parts of the chicken to ensure that it is fully cooked. If you see red meat or red juices, the chicken is not done. Cook for an additional 15 to 20 minutes, then set to the side to cool.
