What Is Prime Rib?

A standing prime rib roast is a pricey cut of meat made out of beef ribs and the ribeye part of a steer. The roast is called a standing rib roast because it rests on the bones, which provides an insulating layer of protection. Boneless or bone-in prime rib roasts are available. The bones do not provide flavour like they would if cooked in liquid, but they provide insulation for the meat and are extremely tasty.

How Long To Cook Prime Rib?

This recipe uses very high heat to sear the roast first, generating a tasty crust, and then continues to cook the roast at reasonably high heat. As a result, the cooking time for this recipe is dependent on a variety of parameters, including the size of the roast, the starting temperature of the meat, the consistency of the oven, and the ending temperature of the meat (rare, medium-rare, etc.). A 5-pound roast will take around 2 hours to roast using this recipe, plus rest time. Allow an extra 10 minutes per pound for larger roasts.

Cooking Tips For Perfect Results

Here are the best tips for perfect results of prime rib:

  • Allow meat to sit at room temperature for at least an hour before cooking for more even cooking. The ends of the prime rib will be significantly more cooked than the middle of it is taken straight from the refrigerator to the oven.
  • As the interior temperature reaches your ideal temperature, could you keep a close check on it? The rate at which the temperature rises will quicken as the roast gets closer to being done.
  • Any dry red wine will suffice. Usually, I’ll go with a Pinot Noir.
  • If you want a perfectly cooked, soft, juicy roast, you must ensure that you get the roast to the exact desired temperature and that you let it rest correctly when cooking a large roast in a roasting pan.
  • Cooking a 4-5 pound roast should take about two hours. The size and starting temperature of the roast, the accuracy of your oven temperature, and how consistently your oven cooks are all factors that affect overall cook time. With an electric knife, slicing the roast is a breeze.

Prime Rib Temperature:

Here are the best tips for temperature for cooking prime rib:

  • Please remove it from the oven when your prime rib roast reaches 10 degrees below your desired final temperature.
  • Rare prime rib should be cooked to 120-125°F, medium-rare to 130-135°F, and well done to 140-145°F.
  • When cooking for a large group, the best rule of thumb is to take your prime rib roast out of the oven when it reaches 120°F and let it rest for 20 minutes while loosely tented with foil.
  • You’ll most likely suit everyone’s tastes for how they like their prime rib roast cooked if you aim for medium-rare.
  • Insert the meat thermometer into the thickest part of the beef, not in the fat or touching the bone, when monitoring the temperature of your prime rib roast. Cook until the rib roast reaches a temperature of 120 degrees F on the inside.

How To Make Prime Rib?

There are several ways to make a prime rib roast:

How To Slow Cook Prime Rib?

The reverse sear method is one of the most classic ways to prepare prime rib. The prime rib will be cooked low and slow in the oven, then finished with high heat to achieve a crisp exterior. The prime rib loses less fluid to the bottom of the roasting pan with this procedure, and it cooks all the way evenly through.

  • Season the beef with a lot of salt and pepper. Allow it to remain in the fridge overnight, uncovered.
  • Allow several hours for it to get to room temperature. Allow 4 hours for it to settle on the counter before cooking. It’s especially crucial to bring the roast to room temperature here because a cold roast will take much longer to cook.
  • Cook it on low heat for a long time. Preheat the oven to 225°F and place the roast inside. According to our timing schedule above, start taking an internal temperature on the roast 30 minutes before it should be done. Please remove it from the oven after it has reached the desired temperature.
  • Allow it to rest. Allow for at least 15 minutes, but up to an hour, of resting time after covering with foil.
  • Sear it in the opposite direction—Preheat the oven to 550 degrees Fahrenheit. Uncover the roast and bake for 7 to 8 minutes, or until it has a good sear on the outside.
  • Cut it up. You may slice it as soon as it comes out of the oven because it has rested. Thanks to the reverse sear time, the prime rib is reheated right before serving.

How to Smoke a Prime Rib?

Smoking a prime rib is similar to roasting a prime rib slowly in the oven:

  • Remove the majority of the fat from the roast’s exterior. Because the temperature in the smoker will be below, you won’t need the fat for insulation, and the smoke, not the fat, will infuse the meat.
  • Season the beef with a lot of salt and pepper. Allow it to remain in the fridge overnight, uncovered.
  • Allow it to cool to room temperature. Allow it to sit on the counter for 2 to 3 hours before smoking to ensure equal cooking.
  • Prepare the grill or smoker. With wet wood chips, you can use a specialist smoker or a charcoal or gas grill set up for indirect heat. Because the smoking process takes a long time, give the roast plenty of time to cook. Place the roast, bone side down, in the smoker.
  • Smoke from the grill should be covered. Maintain a temperature of 200 to 250 degrees Fahrenheit by adjusting the vents. Add extra charcoal and wood chips every 45 minutes to maintain a consistent temperature. Cook for 35 to 45 minutes per pound, or until a thermometer inserted into the thickest portion of the prime rib registers 130 degrees F for medium-rare. It will take about 5 1/2 to 6 hours to cook an 8-pound roast.
  • Pop it in the oven for a few minutes for a crisp crust. Place the roast in a 550°F oven, uncovered, for 7 to 8 minutes, or until crisp on the outside.

How to Grill Prime Rib?

To capture all the juices that will come out of the roast, place a chopping board in a half-sheet pan. Your cutting board’s grooves won’t be able to hold all of the juice, and you don’t want it spilling all over the place. Knives should be sharpened. Get some disposable gloves for your non-dominant hand, which will be holding the roast steady as you slice. Slice one slice for each person, then continue to slice as needed. It’s much easier to reheat or slice into thin slices for sandwiches if you keep the leftover roast in one large piece.

Can You Freeze Prime Rib?

A well-wrapped, raw prime rib roast can be frozen for up to a year. 4 days before roasting, thaw in the fridge. Cooked prime rib roast can also be frozen tightly wrapped, but it shouldn’t be kept in the freezer for more than six weeks. Before reheating, let it thaw for four days in the refrigerator.
A raw prime rib can be kept in the refrigerator for up to three days, while a cooked prime rib can be kept for five days.


When cooking a prime rib, it is essential to remember that the best cooking time for a prime rib roast is about fifteen minutes per pound of meat. The roast should be roasted at a temperature of three hundred and twenty degrees, and the meat should be at a minimum of 120 degrees for medium-rare. While this may seem like a lot of time, it is essential to use a thermometer to ensure your rib is cooked correctly.
