Ingredients
  

For the Prime Rib
  • 1 bone-in prime rib roast (about 4-5 pounds) Beef
  • 2 tablespoons Olive oil
  • 1 tablespoon Kosher salt
  • 1 tablespoon Black pepper, freshly ground
  • 4 cloves Garlic, minced
  • 2 sprigs Fresh rosemary
  • 2 sprigs Fresh thyme

Equipment

  • Roasting pan
  • Meat thermometer

Method
 

  1. Preheat your oven to 450°F (230°C).
  2. Pat the prime rib dry with paper towels. In a small bowl, mix together the olive oil, kosher salt, black pepper, and minced garlic. Rub this mixture all over the prime rib.
  3. Place the rosemary and thyme sprigs on top of the roast.
  4. Place the prime rib, fat-side up, in a roasting pan. Insert a meat thermometer into the thickest part of the roast, avoiding the bone.
  5. Roast for 15 minutes at 450°F (230°C).
  6. Reduce the oven temperature to 325°F (160°C) and continue roasting for about 15-18 minutes per pound, or until the thermometer reaches your desired temperature.
  7. For medium-rare, aim for an internal temperature of 120-125°F (49-52°C). For medium, aim for 130-135°F (54-57°C).
  8. Once the roast reaches the desired temperature, remove it from the oven. Tent it loosely with foil and let it rest for at least 30 minutes before carving.
  9. Carve the prime rib against the grain and serve.

Notes

The resting time is crucial for the juices to redistribute, ensuring a tender and moist roast. You can make a pan sauce with the drippings if desired.
