Season rib roast with mixture of oil, melted butter, garlic, salt, pepper and rosemary. Be sure to season meat on all sides.
Allow the roast to rest on your kitchen counter for about 30 minutes to an hour to reach room temperature.
Place meat on a roasting pan with a rack. Alternatively you can use your instant pot rack over a cast iron skillet (that's what I did!).
Cook the prime rib at 500F degrees for 15 minutes then turn down the heat to 325F degrees and cook for about 15 minutes per pound.
