Ingredients:

  • 1 bone-in prime rib roast (choose a roast that weighs about 4-6 pounds for 4-6 servings)
  • 2-3 tablespoons of olive oil
  • 4-6 cloves of garlic, minced
  • 2-3 sprigs of fresh rosemary or thyme (or 2-3 teaspoons of dried)
  • Salt and freshly ground black pepper

Instructions:

  1. Preparation:
    • Take the prime rib roast out of the refrigerator at least 1-2 hours before cooking to allow it to come to room temperature. This will ensure even cooking.
    • Preheat your oven to 325°F (163°C).
  2. Seasoning:
    • Pat the roast dry with paper towels. This will help the surface to brown nicely.
    • Rub the roast all over with olive oil.
    • Sprinkle the minced garlic evenly over the roast.
    • Season generously with salt and pepper. Make sure to season the entire surface.
  3. Herbs:
    • If using fresh herbs, remove the leaves from the sprigs and sprinkle them evenly over the roast. If using dried herbs, sprinkle them over the roast.
  4. Roasting:
    • Place the roast bone-side down in a roasting pan with a rack, if available. This elevates the roast and allows for better air circulation.
    • Insert a meat thermometer into the thickest part of the roast, making sure it doesn’t touch the bone. This will help you monitor the internal temperature accurately.
    • Roast the prime rib in the preheated oven. Calculate the cooking time based on the weight of the roast:
      • Rare: 15-17 minutes per pound (33-37 minutes per kilogram) for an internal temperature of 120-125°F (49-52°C).
      • Medium-rare: 18-20 minutes per pound (40-44 minutes per kilogram) for an internal temperature of 130-135°F (54-57°C).
      • Medium: 20-22 minutes per pound (44-48 minutes per kilogram) for an internal temperature of 140-145°F (60-63°C).
    • Remember that these are approximate times, and the best way to ensure the roast is cooked to your desired level is by using a meat thermometer.
  5. Resting:
    • Once the roast reaches your desired internal temperature, remove it from the oven and transfer it to a cutting board.
    • Tent the roast loosely with aluminum foil and let it rest for at least 15-20 minutes. This allows the juices to redistribute and ensures a juicy and tender prime rib.
  6. Carving:
    • Slice the prime rib into thick slices and serve immediately. You can serve it with a horseradish sauce or au jus if desired.

Enjoy your perfectly cooked prime rib! Adjust the cooking time to your preferred level of doneness, and you’ll have a delicious and impressive meal every time.
