Instructions
Prep. Take the rib roast from the fridge and let it sit at room temperature for 1 to 2 hours before cooking.
Preheat the oven to 450˚F.
Prep the rib roast. Pat the roast dry with paper towels and generously season it with salt and pepper. Place the roast in a roasting pan and set aside.
Make the garlicky rub. Add the olive oil, rosemary leaves, thyme leaves, and garlic cloves to a food processor or blender; process until chopped up and well combined. Rub the prepared garlic mixture all around the roast.
Roast. Position the beef roast in the roasting pan, bone-side down. Transfer it to the oven and cook uncovered for 30 minutes.
Reduce the heat. Turn the oven's heat down to 350˚F and continue to cook until cooked to the desired doneness. I suggest taking the roast out of the oven when its internal temperature reaches 115°F to 120°F — it’ll keep cooking as it rests.
Rest the meat. Remove the roast from the oven, transfer it to a cutting board, and let it rest for 20 minutes before cutting.
In the meantime, prepare the Au Jus.
Strain the juices. Take the pan juices and strain them through a mesh sieve into a large measuring cup. Discard the bits in the mesh sieve, and pour the strained liquid back into the roasting pan.
Cook down the sauce. Place the roasting pan over the stovetop burners and cook over medium heat. Whisk in the Worcestershire sauce and wine; scrape up all the browned bits from the bottom of the pan. Bring to a boil and cook for 2 minutes.
Finish the au jus sauce. Stir in the beef broth and continue to cook for 5 minutes or until slightly reduced and heated through.
Serve. Slice the prime rib and serve it with the prepared au jus sauce.
Notes
Cooking Time: Estimate 15 to 20 minutes of cooking time per pound.
Please use an Instant Read Meat Thermometer to check for doneness. Whatever you do, avoid overcooking this pricey cut of meat. When the internal temperature registers at 115˚F to 120˚F, pull it out and let it rest on a cutting board for at least 20 minutes.
Cut against the grain: For a tender and juicy bite, observe the direction of the muscle fibers and slice across them, not parallel.
