How to Make Prime Rib Roast With Mustard Horseradish Sauce
- Two hours before roasting, remove the prime rib roast from the refrigerator and let it come to room temperature.
- Preheat oven to 500°F (260°C). Place oven rack in the second lowest position.
- Place the roast, bone-side down, in a roasting pan large enough to comfortably hold it. Generously season the top with 2 teaspoons of salt and 1 teaspoon of freshly ground black pepper.
- Roast for 45 minutes at 500°F (260°C).
- Reduce oven temperature to 325°F (160°C). Continue roasting for 30 minutes.
- Increase oven temperature to 450°F (230°C). Roast for another 15-30 minutes, or until a meat thermometer inserted into the thickest part registers 125°F (52°C) for medium-rare. (Adjust cooking time based on desired doneness.)
- While the roast cooks, prepare the mustard horseradish sauce (see below).
- Remove the roast from the oven and transfer it to a cutting board. Tent loosely with aluminum foil and let rest for at least 20 minutes before carving. This allows the juices to redistribute, resulting in a more tender and flavorful roast.
- Carve the roast against the grain and serve with the zesty mustard horseradish sauce.
