Ingredients
Method
- Take the prime rib out of the refrigerator about two hours before cooking so it reaches room temperature evenly. This helps it cook more uniformly and prevents a cold center with an overdone exterior.
- Preheat your oven to 500°F for the initial sear, then prepare your roast by patting it dry with paper towels—this helps the seasoning stick and promotes better browning.
- In a small bowl, mix together the olive oil, minced garlic, salt, pepper, thyme, and smoked paprika until you get a thick paste. Rub this mixture all over the entire surface of the roast, making sure to get into any nooks and crannies between the bones.
- Place the roast fat-side up in a roasting pan with a rack (or on a bed of chopped vegetables if you don't have one). Roast at 500°F for 15 minutes to develop a good crust, then reduce the oven temperature to 325°F and continue cooking for about 15-20 minutes per pound.
- Use an instant-read thermometer to check internal temperatures: aim for 120-125°F for rare, 130-135°F for medium-rare (the sweet spot for most people), or up to 140°F for medium. The temperature will rise about 5 degrees while resting.
- Remove the roast from the oven and tent it loosely with foil. Let it rest undisturbed for at least 20 minutes before slicing—this is non-negotiable if you want juicy slices that hold together.
- Slice between the bones against the grain into thick pieces, about half an inch to three-quarters of an inch wide. Serve immediately with any accumulated juices from the pan.

Notes
I've made this for dinner parties when I needed to impress without stressing, but more often than not I pull it from my regular rotation because it's honestly reliable. The hard part is waiting long enough before slicing into it—resist the urge or you'll lose half your good meat on the cutting board.
Make ahead tip: Season the roast up to a day in advance and leave it uncovered in the refrigerator so the surface dries out slightly—this gives you better browning when it hits the oven.
Storage: Leftovers keep well in an airtight container in the fridge for up to 4 days, or freeze sliced portions for up to 3 months. Reheat gently in a low oven at 275°F until warmed through to avoid overcooking.
Substitutions: If your butcher doesn't have bone-in, you can use boneless—just reduce cooking time by about 10-15 minutes and watch the thermometer carefully. You can also add a tablespoon of Dijon mustard under the seasoning paste for extra depth if that's what your pantry has on hand.
