Rub olive oil generously over all sides of prime rib roast. Grind rosemary with coffee beans in a spice grinder and sprinkle the mixture over the roast.
Sprinkle lemon pepper and black pepper over the meat, followed by garlic powder and onion powder.
Place roast into a large roasting pan and cover with non-stick aluminum foil.
Roast in the preheated oven for 1 hour and 15 minutes. Uncover and continue roasting until meat is browned and an instant-read meat thermometer inserted into the thickest part of the roast reads at least 145 degrees F (65 degrees C), about 1 hour and 15 more minutes.
Let roast rest for at least 10 minutes before slicing.
