There are few things better than a prime rib roast of beef. This article shows you how to cook a prime rib roast to perfection.
A day or two before roasting
Set boneless prime rib roast on cutting board and pat dry with paper towels. Salt all over with 1 tablespoon kosher salt. Place the salted boneless prime rib roast on a rack in a roasting pan (or on a baking sheet) and refrigerate overnight (uncovered) to air-dry the outside of the prime rib. This ensures a crispier outside.
Ready to roast
Preheat oven to 200°F
In a small bowl combine 2 tablespoons ghee (or olive oil) with 2 tablespoons freshly minced garlic, 2 teaspoons fresh thyme leaves, and 1 teaspoon freshly ground black pepper. Mix well into a paste.
With prime rib roast on rack in roasting pan, rub the garlic and thyme paste all over the roast.
Place roasting pan in preheated oven until the center of the roast reads 120°F on an instant read thermometer for medium-rare. About 4 hours.
Remove roast from oven and tent with foil to rest for at least 20 minutes.
Turn oven temp up to 500°F.
Once the oven reaches 500°F, remove the foil and put the roast back in the oven. Cook until the outside is nicely browned and crisp. About 10-15 minutes. Transfer roast to a cutting board and rest the roast at least 15 minutes. Slice and enjoy!
