Ingredients

• 5 pounds prime rib roast
• 1 cup prepared horseradish
• 1 tablespoon fresh parsley, chopped
• 1 tablespoon fresh rosemary, chopped
• 1 tablespoon fresh thyme, chopped
• 4 cloves garlic cloves, minced
• 2 tablespoons Dijon mustard
• 2 tablespoons olive oil
• 2 teaspoons kosher salt
• 1 teaspoon black pepper, freshly ground

Directions

Step 1

Remove the prime rib roast from the fridge at least 1 hour before cooking to let it come to room temperature. This ensures even cooking.

Step 2

Preheat your oven to 450°F (232°C). Place a rack in the middle of the oven and ensure you have a roasting pan ready.

Step 3

In a small bowl, combine the prepared horseradish, parsley, rosemary, thyme, minced garlic, Dijon mustard, olive oil, kosher salt, and black pepper. Mix until well blended to form the horseradish crust.

Step 4

Pat the prime rib roast dry with paper towels. Place the roast, fat side up, on a roasting rack set inside a roasting pan.

Step 5

Spread the horseradish crust mixture evenly over the entire surface of the prime rib roast, pressing gently to adhere.

Step 6

Place the roasting pan in the oven and roast for 20 minutes at 450°F (232°C) to develop a flavorful crust.

Step 7

Lower the oven temperature to 325°F (163°C). Continue roasting until a meat thermometer inserted into the thickest part of the roast (away from the bones) registers your desired doneness: about 120°F (49°C) for rare, 130°F (54°C) for medium rare, or 140°F (60°C) for medium. This step will take approximately 1 to 1.5 hours depending on the size of the roast.

Step 8

Remove the roast from the oven and transfer it to a cutting board. Tent the roast loosely with aluminum foil and let it rest for at least 20 minutes. This allows the juices to redistribute and makes carving easier.

Step 9

Carve the roast into thick slices and serve warm with your favorite sides, such as mashed potatoes, roasted vegetables, or creamy horseradish sauce.
