Ingredients
  

Main ingredients
  • 6 lbs boneless prime rib Look for well-marbled meat for best results.
  • 1 tablespoon coarse kosher salt Sprinkle generously all over the roast the night before cooking.
  • 3 tablespoons olive oil For the coating mixture.
  • 3 tablespoons Montreal steak seasoning Adds flavor to the roast.
  • 3 tablespoons brown sugar To enhance sweetness in the coating.
  • 2 tablespoons Worcestershire sauce Adds umami flavor.
  • 1 tablespoon minced garlic For flavor in the coating mixture.

Method
 

Preparation
  1. Take the boneless prime rib and place it on a tray. Generously sprinkle coarse kosher salt on all sides. Cover slightly and place in the refrigerator overnight.
  2. Two hours before cooking, remove the prime rib from the refrigerator to bring it to room temperature.
  3. In a mixing bowl, combine olive oil, Montreal steak seasoning, brown sugar, Worcestershire sauce, and minced garlic. Whisk until smooth.
Cooking
  1. Preheat the oven to 200°F (95°C).
  2. Place the prime rib in a roasting pan with the fat side facing up. Evenly spread the mixture over the roast.
  3. Roast in the oven until the internal temperature reaches 120°F (50°C) for medium-rare or 130°F (55°C) for medium doneness. This will take about 3.5 to 4 hours.
  4. Remove the roast from the oven and tent it loosely with aluminum foil. Let it rest for 30 minutes.
  5. Increase the oven temperature to 500°F (260°C). About 10 minutes before serving, place the prime rib back in the oven uncovered to create a crisp exterior.
  6. After 6 to 10 minutes, take it out and let it rest for another 10 to 15 minutes before slicing.
Serving
  1. Slice the roast against the grain on a large cutting board using a sharp carving knife.
  2. Serve with garnishes such as fresh herbs or roasted vegetables, and accompanied by gravy or au jus.

Notes

Allowing the prime rib to rest after cooking is crucial for juicy slices. Consider serving with classic sides like mashed potatoes and seasonal vegetables.
