Now, the big question…
How much prime rib per person should I buy?
General rule of thumb, plan on serving 1/2 pound of meat per person. But I suggest adding an extra pound for just in case (plus, leftover prime ribs isn’t a bad thing at all!). So, if you’re having 8 adults for your dinner party, buy 5lbs boneless prime rib.
If you’re going with a bone-in prime rib, plan on 2 people per rib.
The BEST Prime Rib Roast
- 6 lbs boneless prime rib
- 1 tablespoon coarse kosher salt
- 3 tablespoons olive oil
- 3 tablespoons Montreal steak seasoning
- 3 tablespoons brown sugar
- 2 tablespoons Worcestershire sauce
- 1 tablespoon minced garlic
- Place an unwrapped prime rib on a tray. Generously salt all over and refrigerate overnight to air-dry the outside of the prime rib.
- Bring the prime rib to room temperature before roasting. It’ll take about 2 hours out on the counter.
- Mix olive oil, Montreal steak seasoning, sugar, Worcestershire sauce and garlic until smooth. Then evenly spread the mixture all over the roast.
- Preheat the oven to 200°F (95°C).
- Place the prime rib on a roasting pan fat side up. (I use this roaster, and highly recommend it.) Roast the meat in the oven until the center of the roast reads 120°F (50°C) on a meat thermometer for medium-rare, or 130°F (55°C) for medium doneness, about 3.5-4 hours.

- Remove the prime rib from the oven, cover with a foil and rest for about 30 minutes.
- Meanwhile, increase the oven temperature to 500°F (260°C).
- 10 minutes before serving, pop the prime rib into the oven, uncovered, and cook it until it’s nice and brown, and crisp on the outside, about 6-10 minutes. Rest for 10-15 minutes before slicing and serving.
