Zest both lemons. In a bowl mix together the ghee, garlic, lemon zest, thyme, and rosemary.
Pat chicken dry. Rub ghee mixture all over the chicken and under skin if you can detach the skin without breaking it.
Cut one lemon in half and insert both halves into the cavity of the chicken. Add the onion quarters and a few springs of thyme and rosemary.
Sprinkle some salt, pepper, and paprika on chicken. Roast at 425F for about one hour or until juices run clear. The internal temperature should be 165F.
Remove from oven and let sit for about 10 minutes. It will keep the chicken extra juicy.
