Instructions
-
Preheat the oven to 450 F.
-
Place the prime rib in a large roasting pan, then rub it with butter and coat evenly with salt and pepper. Let the roast stand at room temperature for 2 hours.
-
Sear the prime rib in the hot oven for 20 minutes.
-
Reduce the oven temperature to 325 F and continue roasting until the desired internal temperature is achieved, approximately 15 minutes per pound for medium-rare.
-
Transfer the roast to a platter, loosely tent with foil, and let it rest for 30 minutes before serving.
-
Pour off all but 2 tablespoons of fat from the roasting pan and place it on the stovetop over medium heat.
-
Add flour and cook, stirring, for 5 minutes to form a roux.
-
Whisk in beef broth, scraping all caramelized drippings from the pan. Increase heat to high and cook, whisking often, for 10 minutes until the sauce reduces and thickens slightly.
-
Adjust the seasoning, strain the au jus, and serve alongside the prime rib.
