  1. You need a good meat thermometer to properly cook a good prime rib roast.

    Bring roast to room temperature. Preheat oven to 450 degrees, meanwhile place roast on rack, fat side up, in roasting pan. Season with Kosher salt and freshly ground black pepper. Place meat thermometer in middle of roast, making sure to set probe in the middle of the roast for an accurate reading.

    Place roast in oven, roast at 450 degrees for 15 minutes. Lower oven temperature to 350 and continue to roast until thermometer registers and internal temp of 140 degrees. Depending on your oven, allow about 20 minutes per pound. It could take 50 minutes to a little over an hour. Remove roast from oven and let sit for 20 – 25 minutes. It will continue to cook a little more and it needs to rest before carving.

    This method will ensure medium rare in the middle, medium on the sides and well done on the ends.

  2. Tracy is on the money with her answer A meat thermometer is the best way to gauge doneness I like mine rare though, I look for an internal temp of 125 degrees. let it rest before slicing the temp will rise about 5 degrees for a good rare
