To cook a prime rib roast perfectly, follow these expert steps: 1. Prepare the Roast:
- Remove the prime rib from the refrigerator about 1 hour before cooking to bring it to room temperature, which helps it cook evenly
- Pat the roast dry with paper towels.
- Season the roast generously with salt, freshly ground black pepper, minced garlic, fresh rosemary, and thyme. Mix these with olive oil to create a herb rub and coat the entire roast evenly
2. Optional Marinating:
- For enhanced flavor, marinate the roast overnight in the refrigerator with the herb rub, covered loosely with plastic wrap
3. Preheat Oven and Position Roast:
- Adjust your oven rack so the roast will cook in the center of the oven.
- Preheat the oven to 500°F (260°C)
4. Initial High-Heat Roast:
- Place the roast bone-side down in a roasting pan or on a rack inside the pan.
- Roast at 500°F for 15 minutes to develop a flavorful crust
- For larger roasts, some recommend roasting at 450°F for the first hour, adding water to the pan to prevent burning and promote caramelization of onions or vegetables placed under the roast
5. Reduce Heat and Continue Roasting:
- Lower the oven temperature to 325°F (163°C) or 350°F (175°C) and continue roasting until the internal temperature is about 5-10°F below your desired doneness
- Use a meat thermometer to monitor temperature:
- Rare: 120°F (49°C)
- Medium Rare: 130°F (54°C)
- Medium: 140°F (60°C)
- Medium Well: 150°F (66°C)
6. Rest the Meat:
- Remove the roast from the oven and tent it loosely with foil.
- Let it rest for at least 30 minutes. This resting period allows the juices to redistribute, ensuring a tender and juicy roast
7. Carve and Serve:
- If bone-in, remove the bones by cutting the kitchen twine and separating the ribs before carving.
- Slice the roast against the grain into about ½ inch thick slices.
- Serve with horseradish sauce or pan gravy if desired
This method yields a prime rib roast with a flavorful crust, tender interior, and perfect doneness
. Using a meat thermometer is essential for precision. Enjoy your prime rib with classic sides like mashed potatoes and a fresh salad for a complete meal.
