4.7 from 126 reviews

This Prime Rib Roast recipe delivers a perfectly seasoned and juicy roast with a flavorful herb and garlic crust. Ideal for special occasions, the roast is initially seared at high heat to develop a rich crust, then slow-roasted to medium-rare perfection and rested to ensure tender, mouthwatering slices.

Ingredients

Scale

Prime Rib Roast

  • 46 lb Prime Rib Roast

Seasoning Paste

  • 2 tbsp coarse kosher salt
  • 2 tsp freshly cracked black pepper
  • 6 cloves fresh garlic, minced
  • 2 tbsp fresh rosemary, chopped
  • 2 tbsp fresh thyme, chopped
  • 2 tbsp olive oil

Instructions

  1. Preheat Oven: Preheat your oven to 450°F (230°C) to prepare for the initial high-temperature roasting that will create a flavorful crust on the prime rib.
  2. Prepare Seasoning Paste: In a bowl, mix the kosher salt, freshly cracked black pepper, minced garlic, chopped rosemary, chopped thyme, and olive oil thoroughly to form a paste. This mixture will add savory and aromatic flavors to the roast.
  3. Season the Roast: Generously rub the herb and garlic paste all over the prime rib roast, ensuring every surface is coated for maximum flavor penetration.
  4. Position Roast: Place the seasoned roast bone-side down on a roasting rack inside a roasting pan. This allows even air circulation and heat distribution during cooking.
  5. Sear the Roast: Roast the prime rib at 450°F (230°C) for 15 minutes. This high heat sears the meat, locking in juices and creating a crispy outer crust.
  6. Reduce Heat & Continue Roasting: Without opening the oven door, lower the temperature to 325°F (160°C). Continue roasting until the internal temperature reaches 125°F (52°C) to achieve medium-rare doneness, which typically takes about 1.5 hours depending on the size of your roast.
  7. Rest the Meat: Remove the roast from the oven and let it rest for at least 20 minutes. Resting allows the juices to redistribute throughout the meat, resulting in tender, flavorful slices.

Notes

  • Use a meat thermometer to accurately check the internal temperature for perfect doneness.
  • Resting the meat is crucial to maintain juiciness and improve slicing.
  • The cooking time may vary slightly based on your oven and roast thickness; adjust accordingly.
  • For different doneness levels, adjust the target internal temperature: 120°F for rare or 135°F for medium.
  • Letting the prime rib sit at room temperature for 30-60 minutes before cooking can help it cook more evenly.
