Question: how do you cook a prime rib roast on the food network?
Answer: Preheat the oven to 250 degrees F. Unwrap the roast and place fat-side up on a rack set in a roasting pan. Roast the meat until an instant-read thermometer inserted into the center of the meat registers 120 degrees F, about 4 hours. Remove from the oven and let sit for 1 hour.
