Cook the Prime Rib
Preheat your oven to 450°F (230°C). Place the seasoned prime rib on a roasting rack in a roasting pan. Roast in the preheated oven for 20 minutes, then reduce the temperature to 325°F (165°C) and continue cooking for about 1.5 to 2 hours, or until it reaches your desired level of doneness (135°F for medium-rare).

Prepare the Au Jus
While the meat is resting, pour the beef broth into the roasting pan to deglaze it, scraping up any browned bits. Heat over medium heat until warmed through.
