FAQs

What is the trick to cooking prime rib? ›

Prime rib should be cooked at 500F for 15 minutes, then lowered to 325F for the remainder of the cook time. A good slow roasting prime rib temp is 325F. It is the perfect temperature for medium rare prime rib.

When trying to figure out how much time you need to roast your prime rib, use this simple calculation: weight of the prime rib (in pounds) x 5 = total roasting time in minutes. For example, if you have a 3-pound roast, 3 x 5 = 15 minutes. A 6-pound roast? 6 x 5 = 30 minutes.

Do you cover prime rib roast when cooking? You can cover rib roast when cooking after searing it to help it retain some of its moisture, but it's not necessary. For the best results, leave the roast uncovered until you remove it from the oven or grill and place it at room temperature for resting.

How do restaurants make prime rib so tender? The secret to restaurant-style prime rib is cooking the meat super slow at low temperatures. I recommend cooking prime rib at no higher than 200 degrees F. This cooks the meat very slowly, turning the fat into butter and rendering the proteins juicy and soft.

A thermometer is the only way to guarantee perfectly cooked meat, and a good instant read thermometer is the best one for the job. Aim for 115 to 120°F for medium rare (125 to 130°F after resting), or 125 to 130°F for medium (135 to 140°F after resting).

Use indirect heat in your grill and maintain the temperature between 200 and 250 degrees F. Bring the roast to your desired internal temperature and then crisp the outside in a 550 degree F oven for 7 to 8 minutes.

Place the roast fat side up, bone side down, in a large roasting pan. Cook for 15 minutes, then reduce the oven temperature to 325°F. This allows the heat to sear the roast, trapping the juicy flavors inside while the rest of the meat cooks. On average, each pound of rib needs 15 minutes to cook (i.e., a 4 lb.

Heat the oven to 250°F with the rack in the lower middle position. Place the seasoned rib roast on a greased roasting rack in a roasting tray. Cook for 4 to 5 hours or until the internal temperature in the thickest part of the roast is 125-130°F for medium-rare prime rib, or 135-140°F for medium.

Start on the right foot by letting your prime rib sit at room temperature for a full 3 hours before roasting it.

Is it better to cook prime rib slow or fast? ›

Cooked low and slow in the oven and finished with a blast of heat for the juiciest, most flavorful, evenly cooked prime rib roast. Kenji is the former culinary director for Serious Eats and a current culinary consultant for the site.

The rule of thumb for buying prime rib is to buy one pound per person. A bone-in standing rib roast will feed about 2 people per bone. Also, be sure to consider how many side dishes you plan to serve. If you are preparing a large holiday meal with plenty of other food you could plan on ½ – ¾ pound prime rib per person.

Season the Prime Rib

You can also use olive oil instead of butter and any dried herbs that you like. Spread the soft butter mixture all over the surface of the prime rib and then season the top generously with more fresh black pepper and salt. Don't be shy when seasoning the prime rib before roasting.

A roast is a large cut of meat: it needs more seasoning than you might expect. Season it generously with kosher salt the day before roasting it and let it sit in the fridge uncovered overnight. When you take it out of the fridge before roasting, add pepper and any additional herbs.
