Method
Prime Rib
- 1
Prepare the Prime Rib
Preheat your oven to 450°F (232°C).
- 2
Season the Roast
In a small bowl, mix together the kosher salt, black pepper, garlic powder, and chopped rosemary. Rub the mixture all over the prime rib roast. Drizzle with olive oil and make sure the seasoning covers the entire surface.
- 3
Roast the Prime Rib
Place the seasoned prime rib on a rack in a roasting pan. Roast in the preheated oven for 15 minutes, then reduce the oven temperature to 325°F (163°C) and continue roasting for about 1 hour and 15 minutes, or until the internal temperature reaches 130°F (54°C) for medium-rare.
- 4
Rest the Roast
Remove the prime rib from the oven and let it rest for at least 20 minutes. This allows the juices to redistribute.
- 5
Make the Au Jus
While the roast is resting, pour the beef stock into the roasting pan, scraping up any browned bits from the bottom. Heat on the stovetop to create a simple au jus.
