Perfect Prime Rib

1 . Stage

Remove rib roast from packaging and place in a roasting pan. Let come to room temperature about 30 minutes. Preheat oven to 450º. Generously cover all sides of rib roast with salt and pepper. Place roast in a roasting pan fat-side up. Arrange half the rosemary in the bottom of the pan around the roast.

2 . Stage

Roast 30 minutes, then reduce heat to 350º and cook 1 hour 30 minutes more for medium rare. (Plan on about 15 minutes per pound.) Remove roast from oven, cover with foil, and let rest 20 minutes.

3 . Stage

To serve, slice along ribs to remove them, then separate each rib and put them aside. Slice the roast crossways against the grain. Serve on a platter with the ribs and remaining half fresh rosemary.
