Method

Prepare the roast

• Remove the roast from the refrigerator 2–3 hours before cooking.

• Pat dry with paper towels and place it on a rack in a roasting pan.

Preheat oven and prepare seasoning

• Preheat oven to 450°F (232°C).

• In a small bowl, combine olive oil, garlic, rosemary, thyme, salt, pepper, and Dijon mustard (if using).

• Rub the mixture all over the surface of the roast, pressing it into the meat.

Roast the prime rib

• Place roast bone-side down in the pan. Roast at 450°F for 20 minutes to develop a crust.

• Reduce oven temperature to 325°F (163°C) and continue roasting for 90–120 minutes, depending on size and desired doneness: 

- 120–125°F for rare 

- 130–135°F for medium-rare 

- 140–145°F for medium

Rest the roast

• Transfer the roast to a cutting board and tent loosely with foil.

• Let rest for at least 30 minutes to allow juices to redistribute.

• While resting, prepare any sauces or sides.

Slice and serve

• Carve between the bones into thick slices.

• Serve with horseradish sauce or au jus, and garnish with fresh rosemary if desired.

Tips for Success

• Use a meat thermometer for best accuracy.

• Don't skip the resting period—it’s essential for juicy meat.

• Leftovers make excellent French dip sandwiches or a hearty breakfast hash the next day.
