Ingredients

Scale
  • 4-5 lb Prime Rib Roast (bone-in or boneless)
  • 2 tbsp Olive Oil
  • 4 cloves Garlic, minced
  • 2 tbsp Fresh Rosemary, chopped
  • 1 tbsp Fresh Thyme, chopped
  • 2 tsp Kosher Salt
  • 1 tsp Black Pepper

Instructions

  • Remove the prime rib from the refrigerator at least 2 hours before cooking. Pat the roast dry with paper towels.
  • In a small bowl, combine the olive oil, minced garlic, chopped rosemary, chopped thyme, kosher salt, and black pepper. Mix well to create a paste.
  • Rub the herb mixture all over the prime rib roast, making sure to coat every surface.
  • Preheat your oven to 275°F (135°C). Place the seasoned prime rib roast in a roasting pan, preferably with a rack. Roast for approximately 3-4 hours, or until the internal temperature reaches your desired doneness.
  • Use a meat thermometer to check the internal temperature. Insert the thermometer into the thickest part of the roast, avoiding the bone if you are using a bone-in roast. Use the following guide: Rare: 120-125°F (49-52°C), Medium Rare: 130-135°F (54-57°C), Medium: 140-145°F (60-63°C), Medium Well: 150-155°F (66-68°C), Well Done: 160°F+ (71°C+).
  • For a deeper, crispier crust, you can sear the roast after it reaches the desired internal temperature. Remove the roast from the oven and increase the oven temperature to 500°F (260°C). Return the roast to the oven and sear for 5-10 minutes, or until the crust is nicely browned.
  • Tent the roasted prime rib with foil and let it rest for at least 30 minutes before carving.
  • Carve the prime rib against the grain into slices about ½ inch thick. Serve immediately.
