A perfectly roasted prime rib with a seasoned crust and rosy, tender center is a high protein, carnivore family celebration centerpiece. This luxurious beef roast makes every holiday unforgettable.
Remove the prime rib from the refrigerator at least 2 hours ahead to bring it to room temperature for even cooking.
Preheat the oven to 500°F (260°C). Combine kosher salt, black pepper, garlic powder, and chopped rosemary, then rub the mixture thoroughly over the roast with olive oil.
Place the roast, bone side down, in a sturdy roasting pan fitted with a rack. Insert a meat thermometer into the thickest part, avoiding bone.
Roast for 20 minutes at 500°F to develop a deep, seasoned crust, then lower heat to 325°F (163°C) and continue roasting for 1.5–2 hours, or until the thermometer reads 120°F (49°C) for medium-rare.
Remove the roast from the oven, cover loosely with foil, and let it rest for 30 minutes. Carve thick slices and serve immediately, spooning pan juices over each portion.
