Prepare the Roast: Place the rib roast in a roasting pan fitted with a rack. Generously rub kosher salt over the entire roast, pressing it into the meat with your hand. Refrigerate the roast loosely covered overnight or for up to 4 days.
Bring to Room Temperature: When you're ready to roast, remove the roast from the refrigerator and let it sit at room temperature for about 1-2 hours. This helps the meat cook more evenly.
Herb Rub: In a food processor, combine the olive oil, rosemary, sage, thyme, black pepper, and garlic. Pulse until everything is well combined, but some chunks of herbs remain. Generously rub this herb mixture over the entire roast, pressing it into the meat.
Preheat the Oven: Preheat your oven to 350 degrees F (175 degrees C).
Roasting: Place the roast bone-side down in the roasting pan. Once the oven is fully preheated, put the roast in the center of the oven. Allow it to cook for 12 to 15 minutes per pound, which should be approximately 3 ½ to 4 hours in total. Continue cooking until a deep brown crust forms around the outside of the roast and the internal temperature reaches 120 degrees F (49 degrees C) for medium-rare.
Broiling: Move the oven rack closer to the broiler and preheat the broiler.
Final Browning: After the initial roasting, place the roast back into the roasting pan and under the broiler. Broil until the top of the roast is browned and crisp, about 2-8 minutes. Keep a close eye on it to prevent burning.
Resting: Remove the roast from the oven and transfer it to a cutting board. Cover it tightly with aluminum foil and let the meat rest for 30 minutes. This resting period allows the juices to redistribute, ensuring a juicy and tender roast.
Carve and Serve: After resting, carve the rib roast into slices and serve. Enjoy your deliciously prepared rib roast!
