Prime rib roast is probably the most luxurious piece of meat, and when it’s cooked following the below technique, it melts in your mouth.

Why is it so good? The spinalis dorsi (rib eye cap) blankets the eye of the roast, providing beefy, fatty flavor throughout, while crisping up to add an impressive texture.

I highly recommend choosing a prime rib that carries a USDA grade of choice or prime. If you’re going to pay a little extra for this special cut, you might as well invest in one that will be undeniably incredible. 

Prepping the Prime Rib

There are just a few steps to follow to prep the prime rib.

The peel and trim steps are optional and depend on how fancy you want to get, but I highly recommend following the rub and rest technique before grilling your prime rib. 

How to Grill Prime Rib Roast

Remove the Silver Skin

If you’ve cooked ribs before, you know how important it is to remove the silver skin from the back of the bones. It’s a tough membrane that can ruin a good bite. The rib roast has this membrane, too.

Whether or not you want to remove the silverskin is completely optional. When you eat pork ribs, you pick them up and bite right into the meat. That silverskin can create a tough bite.

With prime rib, however, you eat it with a knife and fork and usually don’t bite right down near the bone. I just like to remove it so the rub has more contact with the meat in between the bones. 

To do this, flip the roast upside down and grab the membrane with a paper towel. Then, peel it off and toss it in the trash.

Frenching the bones

Some fancy restaurants scrape the meat away from each bone, leaving them connected to the roast. 

This creates a really pretty presentation with the bones clean and protruding from the big hunk of beautiful meat. 

My family likes to gnaw on the leftover prime rib bones, so personally, I don’t french them, but if you’d like to try it, you can view a step-by-step demonstration of this technique over at my pork prime rib post.  

The secret trim

Okay. It’s not really a secret to the world, but there is a nice little special trim you can do to add more flavor to the prime rib.

Run your knife between the bones and the meat and continue slicing down until you almost reach the bottom. Make sure not to separate the two.

Now, when you add your rub, you can add rub down through that trimmed area. See nice little secret. 

If you follow this technique, you may want to use some butcher’s twine to secure the bones back to the roast – especially, if you’re cooking this on a rotisserie. 

When it comes time to slice your grilled prime rib, you can quickly remove the twine and remove the bones so they’re not in the way. Then, slice the meat into thin or thick slices, depending on what your diners prefer. 

How to Grill Prime Rib Roast

Rub + Rest

Unlike turkey that gets a wet brine in the fridge, this prime rib gets a dry brine and is left out on the counter.

The counter. What? Is that safe? Yep. It sure is, so long as you don’t exceed four hours.

You want to leave it on the counter, so it gradually comes to temp before it hits the grill. If you put the prime rib on the grill at a 40F-degree fridge temp, it’s not going to cook evenly. The center will take longer to warm while the outside overcooks.

I leave it on the counter for 2-3 hours, and while it’s sitting around waiting, I slather it with robust herbs mixed with my Brisket Rub, garlic, olive oil and my signature ingredient – allspice. While the beef is adjusting to room temperature, it’s breathing in the herbs like an aromatherapy treatment.


Grilling the Prime Rib

The cooking method has 3 stages: slow cook, crust creation and rest.

How to Grill Prime Rib Roast

Step 1: Slow Cook

For an uber-tender prime rib, you want to keep that slow warm-up going by grilling it at a low heat over indirect heat. I like 250F. Be sure to set the prime rib on the grill fat side up. This way, any fat juices will render back into the center of the roast.

You don’t want to cook it all the way at this temp. Instead, aim for an internal meat temperature of 110F degrees. I recommend using a digital thermometer, like the ThermoWorks Smoke. It will alert you when your meat reaches 110F degrees.

A 6-pound rib roast will take about 2 hours.

How to Grill Prime Rib Roast

Step 2: Crust Creation

The best part of a rib roast is the herbaceous crust. To create this, you need to crank the grill heat up to 400F degrees.

Then, just keep on grilling over indirect heat until the internal temp reaches 135F. Remember to change your digital thermometer, so it alerts you when it’s ready.

Step 3: The Rest

Once you roast reaches 135F, pull it off the grill and let it rest for 30 minutes while you get the rest of dinner finished.

This step is so important. If you cut the prime rib right away, all of those magical juices will be lost on the cutting board. By resting the beef, the juices will reabsorb back into the meat, which means every bite will juicy.

If you’re worried about your meat being cold when you serve it, don’t. Your meat is actually going to continue to rise in temperature 5-10F degrees during the resting period. If you’re still skeptical, serve it on heated plates.

How to Grill Prime Rib Roast

How to Please Everyone

I like my beef medium rare, but I respect that there are those who prefer their meat cooked longer. If everyone eating the roast likes their meat medium or medium well, go ahead and cook the meat longer.

If there are just a couple of folks who like their beef extra dead, cut their slice and throw it back on the grill, and cook it to their doneness preference.

Here are the cooking temps to help you out

Medium 145F

Medium Well 150F

How to Grill Prime Rib with Your Grill

Pellet Smoker

This is by far the easiest grill to use because you adjust the temp just like you would an oven. What makes it better than an oven though is that the heat is generated by wood pellets that add a smoky flavor. I use a combo of cherry and oak pellets.

I adjust the temp just like I described above, and I use the grill’s included thermometer to monitor the meat temp.

Gas Grill

To create an indirect heat zone, turn on one burner and adjust it from low to medium until your grill registers at 250F degrees. To get the smoky grill flavor, use an Amazen Pellet Tube Smoker with cherry pellets or create a wood chip foil pouch. Place your meat on the opposite side of the grill and rotate it halfway through the cook.

When it’s time to raise the heat, turn the one burner to high. If the grill doesn’t quite reach 400F, turn on another burner. You may need to rotate the meat during the hot part of the cook to avoid one side of the roast cooking faster than the other. However, try to keep it over the indirect heat to avoid flare-ups.

Charcoal Grill

Light your coals until they have a gray ash. Push them to one side of the grill. Adjust your grill vents, until your grill registers at 250F degrees. Add your meat to the side without coals. You can add wood chips to the coals for smoky flavor, or use hickory charcoal briquettes. When it’s time to increase the heat, adjust your vents. You may need to add more briquettes.

Big Green Egg

Light your coals and add the plate setter to diffuse the heat. Adjust the bottom and top vent, until the grill registers at 250F degrees. Add wood chips for added smoke. When it’s time to increase the heat, open both vents to increase air flow. You can also use a device like the Flame Boss to control the heat automatically.

Oven

I realize I may not have converted all of you to the grill yet. So good news – you can roast this in the oven, too. You just won’t get that same smoky flavor that you get on the grill. Follow the steps above, adjusting the temp from 250F to 400F and monitoring the meat temp.


Answers to your most common questions

Several of you have left comments and asked questions below. To help others so they don’t have to read through all of the comments, here are the most commonly asked questions. 

How large of a prime rib do I need?

When cooking a bone-in prime rib, plan on one pound per person or one bone for every two people. A three-bone prime rib will usually weigh about six pounds and will serve six adults. 

If you plan to serve additional meats and a lot of sides, you can slice the meat thinner and get three servings per bone. 

How long does it take a prime rib to cook?

This recipe is for a six-pound prime rib, which will cook in about three hours (2 hours on low, 30 minutes on high and 30 minutes for the resting stage)

If you’d like to grill a larger prime rib, plan to cook it on low for 20-30 minutes per pound. Then, cook it on high for 45-60 minutes, until it reaches your desired doneness. The resting stage is still 30 minutes.

How to make delicious gravy to go with your prime rib

If you’re a gravy-lover, I recommend roasting some veggies under the prime rib to create a rich, flavorful broth.

Take a pan that is 1-2 inches deep and add a sliced onion, 2 sliced carrots, 2 stalks sliced celery and some fresh herbs. Pour in a cup of beef broth, a cup of water and a 1/2 cup of red wine.  

Place a rack over the pan and add the prime rib right on top for the first part of the cook. Once it’s time to crank up the heat, remove the veggie pan from the grill.

At this point, you can strain the broth and set it aside. Make a roux in a sauce pot by cooking down 2 tablespoons flour and two tablespoons butter. Then, add in the broth and stir until thickened.

    The recipe calls for olive oil. I don’t see where to use it in the cooking process. I assume the oil gets spread over the roast before the dry rub. I’m cooking a prime rib for Christmas dinner.

        Totally your call. If after the first hour, you’re not getting enough drippings, you can add liquid to the pan. I recommend water or beef broth.

          I’m not calling for direct heat in stage 2. I recommend you continue cooking it over indirect heat, just raise the temp. If you move it to direct heat, you risk having flareups.

        • Anonymous February 12, 2021 at 2:16 pm - Reply

          She did call for Direct Heat (directly above): When you raise the temp to 400, the meat should cook over the direct heat. That will help form the crust. Closing the lid is not mandatory, but it helps. Enjoy.

          • Christie Vanover February 21, 2021 at 11:41 am

            I’m sorry for the confusion. That final stage really depends on your grill. If you’re cooking on a pellet grill or a ceramic grill with a diffuser, you can maintain indirect heat at the 400F-degree stage. If you’re using a gas grill, you can start on direct heat at 400F, but keep an eye on it. If you get flareups, move it over to the indirect heat.

    We have two 5 lb roasts to put on the grill at the same time. Any thoughts or adjustments?

    • Christie April 4, 2018 at 8:22 pm - Reply

      You should only need to adjust the time by 30-60 minutes. The adjustment is needed because the cooler meat can bring the temp of your grill down. However, I recommend resting your prime rib at room temperature for 2-3 hours before you grill it. If you do that, the adjustment should be pretty minor.

    How about a pork standing rib roast with pork belly laid over it. Should work the same way, no?

    • Christie May 28, 2018 at 9:32 pm - Reply

      That’s quite a feast you’re planning. You’ll need to cook a pork rib roast longer than beef. Shoot for a temp of around 145. I don’t recommend laying the pork belly on the roast. Belly is best when cooked to about 200, but if you cook your roast that long, it will dry out.

    The first time I used your method the roast turned out absolutely wonderful. I use a jerk seasoning as a dry rub, and of course, allspice is a big part of that. Today I am doing a 5 rib version in my Kamado Joe, and looking forward to it. I do the temperature control with a Flame Boss, and after set up, I grill from my easy chair.

    Hi Christie,

    We were looking for a recipe for grilling prime rib. I came across your website and went with yours. We were having our family for dinner so we purchased a 7lb. prime rib. We live in Ontario, Canada. The cost was $90.00 so I DID NOT want to ruin an expensive piece of beef! We followed your instructions to a T. The prime rib was perfect!! My family loved it and we will all be using your recipe in the future. Thanks very much.

    Hey Christie, I’m a first time prime rib grilller. When you say “heat grill to 250 with indirect heat, does that mean to only turn on half the burners and put the meat on non lit half? Just trying to clarify. Can wait!! Thanks in Advance.

    • Christie Vanover November 10, 2018 at 8:56 pm - Reply

      Yes. That’s exactly right, if you’re using a gas grill. If you’re using charcoal, push the coals to one side, and put the meat over the non-coal side. If you’re using a pellet grill, the deflector plate makes the heat indirect. If you’re using a ceramic cooker, use the plate setter to diffuse the direct heat.

    about how long does it take to go from the 110 degree slow cook portion of the cook to the 135 degree 400 degree part of the cook??

  11. Chop November 20, 2018 at 1:05 pm - Reply

    When you say:
    Crust Creation
    The best part of a rib roast is the herbaceous crust. To create this, you need to crank the grill heat up to 400F degrees.

    Then, just keep on grilling until the internal temp reaches 135F.

    At what point do you do this(crank the heat up)? At the beginning or at the end?

    • Christie Vanover November 21, 2018 at 5:53 am - Reply

      First, you’ll want to cook the roast to an internal temperature of 110F degrees. Once it reaches that temp, then you’ll crank the heat up. Enjoy.

  12. Donny X Bui November 21, 2018 at 1:36 pm - Reply

    Two questions please:
    1) if i want Med Rare @ 135 and resting rises an additional +10deg shouldn’t I remove the meat @ 125 deg?

    2) I have heard of people crusting @ the beginning in the oven vs. at the end as you suggest. Are these two different techniques or is one a lessor approach?

    Thanks. Happy Holidays

    • Christie Vanover November 23, 2018 at 7:41 am - Reply

      If you prefer your meat more rare, you could pull it between 125-130F.

      When it comes to creating the crust, you can do either approach, but I prefer to crust at the end. 1) I feel like I can control the end temp better, and 2) I like the way the smoke works itself into the meat pre-crust.

    When I’m doing the crust process do I take it off and wait for the grill to reach 400* or just leave it on the grill and turn it up? Also, do you rotate the prime rib at all or leave it as is? Thank you.

    • Christie Vanover December 19, 2018 at 9:11 pm - Reply

      I usually leave the prime rib on the grill while it heats up to 400. You only need to rotate it, if your grill has uneven heat, or if you’re heat is coming from one side. For instance, if the charcoal is pushed to one side and the meat is on the other, rotating it will help with even cooking. If you use a pellet grill or Big Green Egg, no rotation needed.

    Hi I am grilling a 15 lb boneless roast I’m just clarifying that I should remove the roast when It reaches 135 degree internal temp from the 400 degree temp grill. I’m feeding 25 people and I am nervous I’m going to blow it. Anything else I need to know? I’m removing from fridge at 6am according to you I should leave out for 3 hours prior. My meal will be served at 630 pm. Is that too early?

    • Christie Vanover December 19, 2018 at 9:17 pm - Reply

      Hi Rebecca. Once it reaches 110, crank the heat to 400 degrees and cook to 135 (or longer if you prefer well done). Once it reaches your preferred doneness temp, remove it and let it rest. 6 a.m. would be too early. I recommend starting at 9 a.m. Let it rest until 11 a.m. to noon. Smoke it at noon for 4-5 hours. Crank the heat and smoke for another 30-60 minutes. Then, let it rest for 30 minutes. You got this!

    • Christie Vanover December 22, 2018 at 9:11 am - Reply

      You’re going to do great, Tony. Just be sure to keep the roast over indirect heat. If you put it in the middle and keep the side burners on, you won’t need to rotate it. If you put it to the left and keep the right burner on, you’ll want to rotate the roast midway through. My recipe is for a 6-pound roast, so you will need to cook it longer. You’ll probably be looking at about 4 hours over at 250F. Main thing is look for the center part to reach 110 degrees. The outer parts will be more done. Another option is to slice that bad boy in half. That would speed up cook time a bit, if you need to.

    Planning to make this for Chrismas Eve! Just for clarification, isn’t it only “Prime Rib” if its prime, otherwise its a “standing rib roast”? That may explain the discrepancy in price.

      Foil will insulate it to help it cook faster, but it will also cause the crust to be more soggy. I think you should be fine with a small grill without the foil.

    I cooked a 6lb standing rib roast on my pellet smoker. I followed your steps to a tee. I let it cook Until It was 135 and then took it off. I wrapped it in foil after removing it to let it rest. When I sliced it open, it was a little more done than I like. Do you recommend not wrapping it or was that the right thing to do? I saw in a previous post you said it would be okay to remove a little earlier for a more rare meat. The crust was delicious but inside was too done for my liking. Any criticism would be appreciated.

    Hi! Thanks for the recipe. I did a trial run with a 5 lb 2 bone roast and it came out great.
    Here’s my dilemma, I’m making a 17 lb 7 bone roast for Thanksgiving, and will be using a gas grill to cook/smoke. What do you suggest for placement? I’m thinking placing it diagonally and then rotating because I’m worried about the side closest to the burner getting cooked un-proportionally Or cut it in 2 and place them on the outside (it’s a 4 burner grill).

    Thanks in advance!

    • Christie Vanover November 27, 2019 at 6:20 am - Reply

      That’s going to be a showstopper. Personally, I would cut it in half. It will also cook faster that way. I would then turn on the two outside burners and cook them in the middle. If you keep it whole, you’re exactly right, you’ll need to do some rotating for an even cook. Again, if it will fit in the middle that might help, so there is more even heat on the two sides.

    I purchased a 100% grass fed Prime Rib roast, which was pricey, so I wanted to cook it right and not ruin it. I cooked a 10 pound rib roast just like you instructed, let it sit unwrapped and it was soooo perfect. During the last couple of minutes of the 400 degree temp, i put it directly over the fire and gave it a nice crispiness, that was my personal preference, but it was perfect for my family and friends!!
    I will definitely do this again..

    I did a 5lb roast on New Years Day and used your rub recipe. I also used some mesquite wood chips and I must say that it was delicious. The only thing that I may do differently next time is to cut back on the salt as we found the outer edges much too salty. Otherwise, my wife said it was the best prime rib roast that I’ve ever done on the grill. Thank you.

      Thanks so much. I’m glad you enjoyed it. If you prefer a less salty rub, you could cut it down to 1 tbsp. salt instead. Let me know if that works better for you.

        Hi. Making this for Christmas dinner. Can’t wait to try your recipe, it sounds awesome. Quick question. When it comes tone for the crust creation part, do I flip the roast fat side down or leave it fat side up?

        • Christie Vanover December 23, 2020 at 10:22 am - Reply

          I usually leave it bone side down the entire time. The ambient heat will help sear the outside.

    Hi Christie. Would you use the same procedure when cooking a boneless leg of lamb?

    Made this on my Traeger yesterday & everyone loved it. Did seem a bit saltier than I prefer, so will reduce to 1 tbsp next time.
    Cook times & temperatures were spot on. This is definitely a keeper recipe!

    Quick question…. Any suggestions on how to gather the drippings when using this grilling method? Would like it to make Au Jus. Thought about putting the roast on a pan to catch but this might alter the temperature of the heat

    • Christie Vanover April 11, 2020 at 5:26 pm - Reply

      I put an aluminum pan under the grill grate with some veggies and a little water to collect the drippings.

    Christie,

    When the roast reaches the 110degree stage what do you do with it as you are waiting on the grill to reach the 400 degree level. Do you remove it from the grill and wrap it? Do you leave it on the grill to continue to cook?

    • Christie Vanover August 17, 2020 at 1:57 pm - Reply

      You can leave it on the grill or remove it and set it on a pan, until the grill heats up. Either method works fine.

    We have successfully done prime rib on the grill in the past – but this process was much easier! Came out perfect. Thanks!

    Hi Christie. I’ll be trying this recipe for Christmas this year. For collecting drippings you suggest a pan underneath the meat. I assume that is just during the slow cook…and to be removed for the 400° cook? A friend told me that she increases the amount of drippings she gets when oven roasting a prime rib by adding a couple of small steaks into the bottom of the roaster. What do you think of doing that?

    • Christie Vanover December 4, 2020 at 7:48 am - Reply

      Yes. Use the pan during the slow cook and remove it when you increase the heat. Adding a couple small steaks sounds like a great idea. Clever friend you have there.

    Hi Christie. I ordered a prime rib for Christmas Eve from my butcher. He told me it would be around 12 to 14 pounds. We like our meat more on the rare side. What temp and how long do you think it will take to cook?

    • Christie Vanover December 13, 2020 at 12:24 pm - Reply

      Sounds like you’re ready for quite a feast. For the first part of the cook, plan on 20-30 minutes per pound at 250F. Then, plan for another hour for the sear portion of the cook and the resting.

    I am going to make this for Christmas this year. I will be feeding 15 people. What pound rib on roast will I need? This recipe sounds great.

    • Christie Vanover December 13, 2020 at 12:22 pm - Reply

      The standard recommendation is 1 lb per person for bone-in rib roast or 1 bone for every 2 people. So I recommend going with a 7-10-bone roast. Enjoy.

    Hi, would like to grill Prime rib in an aluminum pan rather having a pan under the grates. That would make to easier (don’t have to remove when increasing temperature), easier clean \-up, and save juices.

    • Christie Vanover December 18, 2020 at 5:11 pm - Reply

      You can definitely do that. You might want to put a metal rack under the meat in the pan, so it doesn’t sit in the juices and get soggy.

    Thank you for what looks like a fun recipe! The turkeys sold out at Thanksgiving apparently, so this will be the centerpiece of our Christmas dinner.

    We are supposed to be getting devastatingly high winds in Southern New England for Christmas Eve and probably won’t have power, on Christmas Day, so I was searching for ways to cook my prime rib roast. . This sounds awesome, and I will definitely be using it!

    Amazing instruction and recipe! Thank you so much. All about the guideposts (temp) and the process (time). Thank you!

    I followed the cooking instructions on this recipe and it turned out amazing. It was my first time cooking this cut of meat and using a new pit, but it still came out right.

    Most full-sized grills can accommodate a three-bone rib roast (5 to 6 pounds), but a larger roast will take up a lot of space—and since this is an indirect cooking method, the grill area needs to be at least twice the size of the roast. Make sure to measure the space before you buy a roast.

    Outstanding recipe! Thank you, Christie!

    Wanted to duplicate the dinner served at the famous San Francisco Prime Rib restaurant, (now closed) for my wife’s birthday celebration yesterday. Realizing that my infrared gas grill doesn’t have a thermostat temperature control nor do I have a meat thermometer, I chose instead to use my Wolf gas oven.

    Followed the recipe EXACTLY with a 5.78 lb prime rib roast purchased on sale ($8/lb) at our local Safeway supermarket. Perfect result. Only divergence was my choice to cook roast for only about 20 to 25 minutes at 400 deg. (it looked fully cooked) To be honest, the meat was actually tastier than that served at the Prime Rib!! The “rub” recipe was outstanding!

    A complete success!!! Our twin teenage daughters were surprised at how good it was! And of course, my wife is still talking about it!

      Oh wow. That just warms my heart. Thank you. And happy birthday to your wife.

    Hi Christie, Lawrence here. I want to thank you for your guidance in Bbqing my first Prime rib roast, Great success!
    I followed your instructions Almost to the tee, lol I was not sure if I was to put the fat side down once
    I started the “crust creation “ the picture seems that the fat side is still up which I did. Also I took the roast off
    the BBQ at 122 degrees Fahrenheit. You said that the roasts temperature would continue to rise between
    5-10 degrees wile it Rested! I prefer my roast medium rare, taking it out at 130-135 would add 5-10 degrees
    and make it beyond Medium rare!
    Thanks again Christie

    Thank you for your recipe and for monitoring these comments so closely. I made prime rib for my wife for Mother’s Day and served with with garlic mash and maple glazed carrots (we live in Canada, eh?). I used indirect heat on my gas grill with cherry wood in the smoker box. It was very good, but I would suggest using far less salt. The meat was perfect, and the crust was good, but there were definitely bites that were way too salty. I did a double take when preparing the roast when I saw that the recipe calls for 2 tablespoons of Kosher salt so I knocked it down to one and half, but it was still too much. I am not sure if anyone else found this, but I thought to share.
