A simple, traditional boneless prime rib recipe that ensures a tender and juicy roast with a gorgeous, crispy crust.
Pat the prime rib dry with a paper towel. Lightly score the fat cap of the roast by making a cross-hatch pattern with a sharp knife. Do not cut too deep.
Drizzle canola oil over the roast and rub to adhere. Sprinkle with Kosher salt and black pepper, and rub all over once more.
If you have time, intensify the flavor of the beef by transferring the roast to a rimmed pan and placing it in the refrigerator (taking care to avoid any cross-contamination) overnight or up to 3 days, uncovered. If you do not have time, proceed directly to step 4.
Preheat the oven to 450° and have ready a rack fitted in a roasting pan or over a sturdy rimmed baking sheet.
Remove the roast from the refrigerator to sit at room temperature 1 hour prior to roasting to remove the chill. Then, transfer to prepared rack and pan.
Roast for 15 minutes at 450°. Decrease the temperature to 300° and roast until the internal temperature reaches 120°, about 1 hour and 45 minutes to 2 hours more.
Remove from the oven and allow to rest at least 15-20 minutes before carving. Slice the roast in 3/4" slices, serve and enjoy.
Once the roast has reached 100°, it is safe to assume it will rise in temperature 2° every 3 minutes.
