Place thawed bird in roasting pan, and dry with paper towels. Be sure to dry every nook and cranny. Liberally salt the inside and outside of the turkey. Place in a fridge, uncovered, on the lowest shelf overnight. 24 hours minimum. 

Remove the bird from the fridge an hour before you want to bake it. There is no need to rinse the bird, and leave the juices in the bottom of the roasting pan. Pick the bird up, and place on a small roasting rack to pickup off the bottom of the pan. Stuff the bird with lemon, onion, and sage. Tie the legs together, and brush melted butter all over the bird. Sprinkle the tablespoon of poultry seasoning over it, and rub liberally to spread around. Cover the bird on the roasting pan tightly with foil, and bake at 350 degrees until the internal temperature reaches 160 degrees. 15 minutes per pound. Right at almost 4 hours. The last half hour, you’ll want to remove the foil and let the skin brown. You can baste the bird, if you would like during this half hour. 

Once the turkey has reached 160 degrees, remove from the oven and cover tightly with foil to let it reest for 15-20 minutes before slicing.
