A garlic-studded prime rib with an aromatic crust and juicy, rosy center is a high protein, carnivore-approved holiday masterpiece. This family celebration roast delivers bold, beefy perfection.
Remove the prime rib from the refrigerator and let it rest at room temperature for at least 1 hour before roasting. Preheat oven to 500°F.
Peel 8 garlic cloves. Make 8 deep slits around the roast with a small paring knife and insert a garlic clove into each pocket.
Pat the roast dry with paper towels. Rub the entire surface with olive oil to help the seasonings adhere.
Combine kosher salt, black pepper, chopped rosemary, and thyme in a small bowl. Press the seasoning mixture evenly onto all surfaces of the roast, ensuring the crust will form.
Place the roast bone-side down on a rack in a roasting pan. Roast at 500°F for 20 minutes to develop a rich crust, then reduce the oven temperature to 325°F without opening the door.
Continue roasting until an instant-read thermometer inserted into the thickest part registers 125°F for medium rare, about 90–120 minutes depending on size. Check temperature after 90 minutes.
Remove the roast from the oven and tent loosely with foil. Let rest 25–30 minutes before carving to allow juices to redistribute.
Slice between the bones for generous servings. Serve immediately with pan juices, if desired.
