Method

Preparation

  1. 1

    Prepare the Prime Rib

    Take the 16 oz Prime Rib Roast out of the refrigerator and let it sit at room temperature for at least 1 hour before cooking. This will allow for even cooking.

  2. 2

    Preheat the Oven

    Preheat your oven to 250°F (120°C). This low roasting temperature will help to tenderize the meat.

  3. 3

    Season the Meat

    In a small bowl, combine the kosher salt, black pepper, garlic powder, and chopped fresh rosemary. Rub the mixture all over the prime rib roast. Drizzle the olive oil on top and rub it in to coat the meat evenly.

Roasting

  1. 4

    Roast the Prime Rib

    Place the seasoned prime rib roast on a roasting rack in a shallow pan. Insert a meat thermometer into the thickest part of the roast, avoiding the bone. Roast in the preheated oven for approximately 2 to 2.5 hours, or until the internal temperature reaches 130°F (54°C) for medium-rare.

  2. 5

    Rest the Roast

    Once the prime rib reaches the desired temperature, remove it from the oven and cover it loosely with aluminum foil. Let it rest for 15-20 minutes. This allows the juices to redistribute and keeps the meat juicy.

Serving

  1. 6

    Slice and Serve

    After resting, use a sharp knife to slice the prime rib against the grain into thick slices. Serve with horseradish sauce and au jus on the side if desired.
