Remove bag with giblets/liver from the inside of the chicken & discard. Rinse chicken well, inside and out. Pat dry with paper towels.
Rub the oil all over the outside of the chicken. Mix all seasonings in a small bowl, then place 1/2 of the seasonings under the skin. Rub the remaining seasoning on the outside of the chicken. Place the cut up lemon inside the cavity of the chicken. Place the chicken (breast side up) in a large pan on a rack. Pour 1 cup of water in the bottom of the pan.
Preheat the oven to 450 degrees. Cook the chicken for 15 minutes. Lower the temperature to 350 degrees, then cook for an additional 2-1/2 hours. Baste a few times while cooking. If the skin starts to get too brown, place tinfoil over the chicken. Let chicken cool for 15 minutes (with tinfoil covering it) before serving.
