Prime Rib Tips

Here is the formula: Multiply the exact weight times 5 minutes. For me it was 5.35 x 5 = 26.75 minutes, which we round up to 27. You'll cook your room-temperature prime rib at 500 degrees F for exactly that many minutes.

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.

Brown the roast at 500°F (or as high as your oven will go) for 15 minutes. Lower the oven to 325°F to finish roasting: Reduce the oven temperature to 325°F. Roast in the oven until the thermometer registers 115°F for rare or 120° for medium rare, and 130°F for medium.

Look for a well-marbled and bone-in Prime Rib roast for the best flavor and tenderness. Bring the Meat to Room Temperature: Remove the Prime Rib from the refrigerator at least 1-2 hours before cooking. Letting it come to room temperature ensures more even cooking.

Start by cooking your prime rib at 500°F for 15 minutes and then lower the oven temperature to 325° F and cook for 10-12 min per pound for rare, or 13-14 min per pound for medium rare, or 14-15 min per pound for medium well. A meat thermometer is essential to ensure you cook it perfectly!

Putting a dry rub on too early increases the likelihood of it being washed off or knocked loose before you get the beef cooked. Aside from seasoning mixes designed to go on up to one day before cooking for brining purposes, you'll only want the dry rub on the Prime Rib in time for the start of cooking.

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 salt helps trap the heat to better cook the prime rib. “It conducts the heat and seals it,” says Betz.

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.

Searing is an important part of roasting a prime rib. Searing the roast first will kill the surface bacteria, which is a nice touch, especially when you are roasting at lower temperatures.

Should you put water in the bottom of the roasting pan when cooking prime rib? ›

Placing the oven rack too high up will cause your roast to brown too quickly and burn! After 30 minutes in the oven, add a ½ cup of water to the bottom of the roasting pan. The key is to allow the onions to brown and caramelize while roasting, but not to burn and smoke in the fat.

Prime rib has a large “eye” of meat in the center, which is juicy, tender, and marbled with fat. This eye has a fat-marbled muscle around it, and the whole thing is surrounded by a thick cap of fat. This means that prime rib is tender, juicy, and extremely flavorful because the muscles aren't heavily used.

Cook the prime rib at 500 F for 20 minutes. Then, turn the heat down to 325 F and cook it for another 1.5 hours – or until the internal temperature reaches. Once it's done, allow it to cool for 40 minutes under a foil tent. Then, slice it, serve with your favorite mashed potatoes, and enjoy!

Overcooking the Prime Rib

That's why prime rib is so expensive: it's a huge piece of extremely good beef. Therefore, it's important not to cook it beyond medium-rare. Going past that temperature means the roast will no longer be tender.

You'll cook the prime rib low and slow in the oven, then crank up the heat at the end to achieve a crisp outside. This method has several advantages: the prime rib loses less juice to the bottom of the roasting pan and it cooks evenly all the way through.
