Prime rib has always been my husband’s go-to main course for special occasions. When we dine out for anniversaries or Valentine’s Day he tends to order prime rib without hesitation, and his delight when it appears on the table is unmistakable. This year, with fewer social outings, I decided to surprise him by preparing prime rib at home—restaurant style.
I chose a boneless roast for this dinner. While bone-in roasts can add extra depth of flavor, a boneless cut still delivers outstanding taste because of the generous marbling in this particular cut. Boneless also makes slicing and presentation simpler, so you can plate even, attractive slices for a festive meal.
The Keys to Perfect Prime Rib
Getting prime rib right is about a few critical steps more than complicated techniques. First, allow the roast to come to room temperature before cooking. For most roasts this takes about 3–4 hours after removing it from the refrigerator. Starting from room temperature helps the roast cook more evenly from edge to center.
Second, wait to salt the meat until just before it goes into the oven. Salting too far in advance can draw moisture out of the surface and dry the roast. When you’re ready, season the exterior generously—don’t be shy with the salt—and finish with freshly ground black pepper and your preferred steak seasoning.
A simple butter rub is all you need: soften unsalted butter to room temperature and mix with freshly ground black pepper and a steak seasoning of your choice, then spread the mixture all over the roast. Place the roast on a rack in a roasting pan so air can circulate and the exterior browns evenly.
For cook time, use this easy rule: round the roast weight up to the nearest whole pound, then multiply by 7 minutes per pound for a reliably medium-rare center. For example, a 4.76-pound roast cooks about 35 minutes. If you prefer a slightly more done outer edge and a medium-rare center, increase to 8–9 minutes per pound.
Once the calculated cook time finishes, turn the oven off and leave the roast inside with the oven door closed for two hours. This gentle carryover resting period completes the cooking and lets juices redistribute; resist the urge to peek, as opening the door will release heat and interfere with this process.

Restaurant Style Prime Rib Roast
Melt-in-your-mouth prime rib cooked at home with the kind of flavor and texture you’d expect from a quality restaurant.
Ingredients
- Prime rib roast, brought to room temperature
- 1/2 cup unsalted butter, room temperature
- 1 tablespoon freshly ground black pepper
- 1 teaspoon Montreal-style steak seasoning (or similar)
- Kosher salt, generous amount
Instructions
- Bring the rib roast to room temperature, about 3–4 hours out of the refrigerator.
- Preheat the oven to 500° F (260° C).
- In a small bowl, mix the softened butter with freshly ground black pepper and the steak seasoning.
- Spread the butter mixture evenly over the entire surface of the roast.
- Season the roast generously with kosher salt just before placing it in the oven.
- Set the roast on a rack in a Dutch oven or roasting pan. Roast for 7 minutes per pound (rounding up) for medium-rare. Increase to 8–9 minutes per pound for a slightly more done exterior.
- When the cook time is complete, turn the oven off and leave the roast inside with the door closed for 2 hours. Do not open the oven during this time.
- Remove the roast, slice against the grain into even slices, and serve immediately.
Notes
This method yields a medium-rare prime rib. For medium, extend the cook time to 8–9 minutes per pound.
Tip: Use a sharp carving knife and slice thinly against the grain for the most tender bites. Letting the roast rest as directed prevents juices from running out when sliced.
