- Remove the prime rib from its packaging and pat it thoroughly dry with paper towels. This step is crucial for achieving a beautiful sear. Let the roast sit at room temperature for about 1 to 2 hours before cooking. This allows for more even cooking.1 approx. 4-5 lbs boneless prime rib roast
- In a small bowl, combine the coarse sea salt, freshly cracked black pepper, garlic powder, dried thyme, and dried rosemary. Mix well to ensure all the spices are evenly distributed.3 tablespoons coarse sea salt, 2 tablespoons freshly cracked black pepper, 1 tablespoon garlic powder, 1 teaspoon dried thyme, 1 teaspoon dried rosemary
- Generously rub the entire surface of the prime rib roast with the prepared seasoning blend. Make sure to coat every side, pressing the seasonings gently into the meat.1 approx. 4-5 lbs boneless prime rib roast
- In another small bowl, combine the softened unsalted butter, grated Parmesan cheese, minced garlic, and finely chopped fresh parsley. Mix until you have a cohesive paste.1/2 cup unsalted butter, softened, 1/4 cup grated Parmesan cheese, 2 tablespoons fresh parsley, finely chopped, 2 cloves cloves garlic, minced
- Preheat your oven to 450°F (230°C). Heat a large, oven-safe skillet or roasting pan over medium-high heat with a drizzle of olive oil. Once the oil is shimmering, carefully place the seasoned prime rib into the hot skillet, fat-cap side down if applicable. Sear for 2-3 minutes per side until a nice brown crust forms. This initial searing locks in juices and builds foundational flavor.olive oil, 1 approx. 4-5 lbs boneless prime rib roast
- After searing, remove the roast from the skillet and place it on a cutting board. Evenly spread the Pepper Parm butter mixture over the top and sides of the roast, pressing it gently to adhere.1 approx. 4-5 lbs boneless prime rib roast
- Place the prime rib, crust-side up, into the preheated 450°F (230°C) oven. Roast for 15 minutes at this high temperature.1 approx. 4-5 lbs boneless prime rib roast
- After 15 minutes, reduce the oven temperature to 325°F (160°C). Continue roasting until the internal temperature reaches your desired level of doneness. Use a meat thermometer inserted into the thickest part of the roast (avoiding bone):
- 120-125°F (49-52°C) for Rare
- 130-135°F (54-57°C) for Medium-Rare (recommended)
- 140-145°F (60-63°C) for Medium
- A general guideline for roasting time is about 13-15 minutes per pound at 325°F (160°C) after the initial sear and high-heat blast. So, for a 4-5 lb roast, expect about 3 to 4 hours of total roasting time.
- Once desired temperature is reached, remove the prime rib from the oven. Tent it loosely with aluminum foil and let it rest for at least 20-30 minutes before carving. This resting period is critical for allowing the juices to redistribute throughout the meat, ensuring a moist and tender final product.
- After resting, carve the Pepper Parm Prime Rib into thick slices. Serve immediately with your favorite side dishes.
Notes
Leftover Pepper Parm Prime Rib will stay fresh in the refrigerator for up to 3-4 days. For reheating, reheat individual slices in a single layer in a baking dish with a splash of beef broth or water, covered tightly with foil, in a preheated oven at 300-325°F (150-160°C) until warmed through.
