Combine the onion salt, thyme, savory, orange peel and pepper; rub half of the herb mixture under the loosened skin. Rub chicken skin with oil; sprinkle with remaining herb mixture.
Bake at 375° for 1 1/2 to 2 hours or until a meat thermometer reads 180°.
Let stand for 10-15 minutes.
Remove skin before carving. Skim fat and thicken pan juices for gravy, if desired.
