Preheat the oven to 450F. Pat the chicken dry with paper towel. Position oven rack in the middle of the oven.
Mix the seasonings in a small mixing bowl: salt, pepper, rosemary, lemon zest, lemon juice and olive oil. For best flavor, soak the chicken in the mixture and cover on all sides so it is well saturated.
Place the meat in a covered shallow roasting pan. Bake for 30 minutes. Check the meat and flip to the other side. Continue roasting until the meat is 160F in the thickest part, approximately another 30 minutes. Move the chicken to a plate to rest, and cover with foil. Serve while hot.
