Instant Pot Prime Rib Roast

I just have to type the words “instant pot prime rib roast” and I am licking my lips at the thought of tucking into the best cut of meat in the instant pot.

But I am also well aware that prime rib is one of the most expensive cuts of meat and is certainly not economical like an instant pot chuck roast.

But its also the most flavoursome and tender meat (well apart from fillet steak) that I can cook at home using my kitchen gadgets.

After buying a beautiful organic 4 rib of beef from my local butchers for just short of £130.00, I wanted it to go beyond one roast beef dinner and for me to feel like I have got value for money.

That is why I decided to do prime here on Recipe This for this week. I am sure I am not the only one that loves prime rib but hates the price for one meal only and wants to make several meals out of one 4 rib of beef.

We will be halving it for two main roast rib joints, making soup with the rib bones and best of all, yummy leftover meals.

Today is day 1 of our delicious week dedicated to prime rib with instant pot prime rib and we will be back tomorrow with more prime rib favourites.


Plus, as well as our free newsletter, we also have a free instant pot mini course. It is ideal for instant pot beginners or those that want to get more confident with their instant pot. The free course runs for 5 days with a new lesson delivered each day to your inbox.

Can You Cook A Rib Roast In An Instant Pot?

Yes, you sure can. The instant pot pressure cooker and any other electric pressure cooker, does an impressive job of cooking any roast beef.

This of course includes a rib roast.

Though we do recommend that you cook a boneless rib roast rather than bone in and then reserve the rib bones for a yummy instant pot beef soup.

What Do You Call Instant Pot Beef Roast?

I originally published this recipe way back in 2017 and titled it an instant pot beef roast. I have now edited it today and renamed it an instant pot prime rib roast, as I feel like beef roast is too broad a term.

Beef roast could be a chuck roast, topside of beef, silverside, brisket and so many other cuts.

But during the process of renaming and some research among family and friends I realised that prime rib was not its only name.

This amazing meat might be referred to as:

  • Instant Pot rib roast
  • Instant Pot rib of beef
  • Instant Pot ribeye roast
  • Instant Pot cross rib roast
  • Instant Pot standing rib roast

Dominic said that during his years as a chef specialising in roasts, it would always be referred to as a 4 rib roast.

And our butchers (who we purchased it through) named it a rib of beef and I would think of it as a rib roast.

Do comment below with what it is called where you live as I find it so interesting how many different names it has.

Preparing Your Instant Rib Roast

The first step is to prepare your rib roast for the instant pot is deciding how you wish to cut it and if you are eating it bone in or boneless. And if any leftover meals are going to be planned, or if its just a one off roast beef for a Sunday dinner or a special occasion.

What we did in preparing our rib roast was to separate it into two.

Our rib roast was a 4 rib roast and weighed more than 5 kilos which is 11 pounds. Even if we had wanted to cook it all, there is no way that it would have fitted in our instant pot pressure cooker.

Therefore, Dominic was kind enough to slice down the middle and create two ribs of beef.

cutting your rib roast

Of course, these would fit in the kitchen gadgets easily.

BUT we find that rib of beef in the instant pot is much better, if you go with a boneless version.

Plus, if we do a boneless version, we can cut out the ribs and then use the rib bones for an amazing soup.  

Of course, you might not need to consider this, as you might have a ribeye roast that has been rolled and is already prepared for you.

Beef Rib Roast Instant Pot Seasoning

Some cuts of beef are so amazing, that they only need a light seasoning because you want to taste the flavours of the meat.

Beef rib roast is one of them, which is wonderful for you, because it means there is not much effort on your part.

What I recommend is that you season your rib roast with salt, pepper, and some garlic powder.

Then leave it in the fridge overnight.

The next day your prime rib roast is ready for cooking in the instant pot.

Rib Roast Instant Pot Recipe Ingredients

Rib Roast Instant Pot Recipe Ingredients

Roast – Whether its instant pot prime rib or instant pot rib roast, you will want a good one, for cooking in the instant pot. Opt for boneless or cut out the bones yourself. Also note, that you want one that will fit in your instant pot. We used a 2.5kg 2 rib roast which is 5.3lbs.

Oil – This may sound like an odd ingredient to add to this instant pot rib roast recipe, but it creates a glue for your seasoning to stick to. It also stops your rib roast from going dry during the pressure cooking process.

Seasoning – Keep the seasoning basic because the flavour is in this amazing cut of meat, not in heavy seasoning. I recommend salt, pepper, and garlic powder. You can include something simple like sweet paprika or some onion powder too.

Stock. Your beef will be so much better if you use beef stock rather than water in the instant pot. We make our own frozen beef stock cubes and then load them into the instant pot with the beef.

Onion. I also add an onion and deglaze it first in the instant pot with some extra virgin olive oil. The Instant Pot can then be deglazed with some red wine.

Then for the kitchen gadgets that we have used in this easy instant pot beef roast recipe, it has just been our instant pot pressure cooker. We have this one and it is amazing for many cuts of beef.

How To Cook Rib Roast In An Instant Pot?

instant pot rib roast step by step
  • Prepare. If you have a large prime rib, or one that will not fit in the instant pot, cut it to size for the instant pot and remove any bones.
  • Season. Add a light seasoning of salt, pepper, and garlic powder to your prime rib. Then load it into the fridge and leave it overnight for the flavour to marinate the meat.
  • Sauté. I recommend that you sauté an onion with extra virgin olive oil and deglaze with red wine. This creates a fantastic base for a beef stock and of course you can use the juices from this and the beef rib that have dripped down to make a gravy.
  • Dump. Add in the trivet and dump your rib of beef over the trivet.
  • Cook. Set the valve to sealing and pressure cook for 10 minutes, followed by a 30 minute natural pressure release.
  • Sit. Removing the lid allow to rest for 5 minutes before slicing and enjoying.

How Long To Cook Rib Roast In Instant Pot?

The instant pot rib roast cooking time is JUST 10 minutes, but also note that we are doing a 30 minute natural pressure release.

This produces a medium rib roast via the instant pot and is the best cook time to do.

You see, the 30 minute natural pressure release, cooks the meat slow. You still have the heat from pressure cooking, but it’s a lower temperature, similar to how you cook meat slower in a slow cooker.

  1. I am Cooking a 1.27 pound cross rib roast how long would you cook this? We have a small family so we always get smaller roast’s. Do you have any suggestions for this? I can’s find a cook time anywhere.

    1. Hi Misti,

      With it been so small compared to the one we cooked and depending on how you like it been cooked either well done, medium, medium rare i would cook it for 4 minutes and see if it is to your liking but also with it been pressure cooked it could shrink to a really small size 🙂

  2. 5 stars
    I have a 3pd cross rib roast, already removed bone and put aside. That is weight after bone removed. What would you recommend for cook time? Pressure and release time.

    1. Hi Melissa,

      It would depend on how you like it cooked. If you like it well cooked leave it for the full 10 minutes but if you like it slightly under then 6-7 minutes should be fine. Then leave for 15 minutes instead of what the recipe says which is 30 minutes, but these times all depend on how you like it cooked 🙂

  3. so the cooking time is always 10 minutes & the resting time is what counts – I have a 3.3lb roast – 10 minutes & then maybe 15 more before release for med/rare?

    1. Hi Dagan,

      Ours was just short of 5.5lbs and we did it for those times so I would do 8 minutes cook and 10 mins rest as i think it might be over your med/rare for that sized joint 🙂

    1. Hi Mary Ann,

      If you have the same size rib roast as we did i would add another 5 mins onto the cook time 🙂

  4. 5 stars
    Made this, it was well received. i would lessen the liquid just a skosh. I added mushrooms to the pot and yams. all were ready when the meat was. i will also add a little more garlic, and some rosemary to the pot.
    was good texture and good heat.

    thank you.

  5. 5 stars
    When you say: “place warm water into the bottom of the inner pot, then place the roast on top” do you mean on the rack/tricket (sp?), or in the water?
