Preheat oven to 450°.
Set the turkey in a roasting rack (or see alternative in notes below) and place on a sheet pan.
Roast for 15 minutes and then lower oven to 350° until meat thermometer reaches 165° (cooking time is approximately 20 minutes per pound).
Cover with foil and let rest for 10 - 15 minutes before removing breast from bone and carving into slices.
Garnish option: before roasting, slide whole sage leaves under skin for a pretty presentation.
