Leftover Prime Rib Soup

Do you see a theme going on at Recipe This? You might be thinking that I am talking about our prime rib week. After all, we have already shared with you this week air fryer prime rib, instant pot prime rib and slow cooker prime rib stroganoff.

But no, I am not talking about that, but more about my obsession with cooking beef roasts and transforming them into wonderful leftover roast beef soups in the instant pot pressure cooker.

Ones that are easy to make and that you can easily make at home in your instant pot. Where you don’t need many leftovers to make them happen and that small amount of roast beef can really add flavour to an instant pot soup.

Two weeks ago, we showed you how to make leftover brisket soup and this recipe today for prime rib soup is similar in many ways.

It is cheap to make with what I already have in, it uses the last bit of prime rib that we have not eaten yet, its so easy my five year old could prep it and best of all it will feed your family for a couple of days.

But best of all, because they are similar and also similar to some of our other leftover roast beef soups, you can easily swap the roast beef, if you don’t have leftover prime rib.


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.

What Is Beef Rib Soup?

Beef rib soup, prime rib soup, standing rib soup, are all one of the same and are soups make from prime rib leftovers, or as you might call it rib roast soup.

You can use spare meat, or the bones, to make a delightful, hearty soup or stew that will keep you full for hours and hours.

In fact, after a small bowl of this beef rib soup, I did the school run and collected the kids. I didn’t have much but was crazy full all the way to school.

Can You Make Prime Rib Roast Soup In The Instant Pot?

You most certainly can. Though note, if doing prime rib bones soup, that you might need to trim your bones to size, so that they can fit in the instant pot.

Because we are already using our prime rib bones for bone broth, we are just using a small portion of chopped prime rib in this soup.

Prime Rib Soup With Potatoes

Did you know the easiest way to make a prime rib soup is with potatoes? The potatoes help to create a creamier soup, you can then keep the soup gluten free and best of all, its economical and will make a bigger soup and fill people up more.

You also only need 2 medium/large white potatoes and most people will already have these in their pantry.

Your Prime Rib Soup Instant Pot Recipe

Though this prime rib is your own and you can tailor to how you like it and how you will enjoy it most.

You know what vegetables you like, you know what potatoes you would prefer, and you know what items you already have in your pantry.

The version of prime rib soup in the instant pot that I am making is a Mexican one. I am doing this because I can stretch the leftover soup to feed more people. I can add in frozen corn and drained black beans, and I can add in my favourite Mexican seasonings and then serve it with some fresh bread rolls.

Leftover Prime Rib Stew

Or if you would rather make a leftover prime rib stew, then that is easy to create too. Simply reduce the liquid and don’t refill your salsa jars and you have a stew. It’s the only change you need to make in this recipe.

Prime Rib Soup Recipe Ingredients

Prime Rib – You don’t have to have a large quantity of leftover prime rib to make this work. Note that this leftover roast beef soup would feed at least six people, so if there is just two of you, then you could use less.

Veggies – I love my veggies in my soup and will go with what I have in, rather going out and buying lots of extra ingredients. I added onion, fresh tomatoes, tinned tomatoes, courgette, salsa, carrots, and frozen corn and frozen peas. My family always joke when they see me with frozen corn that I am short on food and just trying to stretch it that little bit further.

Beans – Now this is another great way to fill your family up and feed more people. I had a can of black beans in the pantry that needed using up and added it in. You can swap black beans for chickpeas, white beans, kidney beans etc.

Potatoes – We also used a couple of medium to large white potatoes. You can do the same and it will make it more filling. Or swap the potatoes for sweet potatoes, butternut squash etc.

Seasoning – Next you need the seasonings, and you can mix and match with your own preference. Though start with salt and pepper and then we used Mexican seasoning, and coriander leaves. We also recommend adding extra after pressure cooking as the instant pot can strip some of the flavour.

Then for the kitchen gadgets that we have used in this prime rib soup instant pot recipe, it has just been our instant pot pressure cooker. We have this one and it is amazing for soups, stews, and casseroles.

How To Make Prime Rib Soup?

instant pot prime rib soup step by step
  • Sauté. Slice your onion and sauté with extra virgin olive oil in the instant pot. Then cancel, add in the chopped fresh tomatoes and the juices from the tomatoes will help you deglaze the instant pot.
  • Slice. Prep your vegetables and potatoes and peel and slice any that need it.
  • Dump. Place everything else (apart from the frozen corn and peas) into the instant pot and stir.
  • Cook. Set the valve to sealing and pressure cook for 7 minutes, followed by a quick pressure release.
  • Stir. After releasing pressure, stir in frozen corn and frozen peas. The corn and peas are fantastic at heating through with the warmth of the instant pot soup so no need to thaw it first. Then add in extra seasoning if you feel it needs it.
  • Serve. Then serve with warm bread rolls such as our air fryer pull apart bread or our bread machine dinner rolls.

How To Thicken Prime Rib Soup?

Worried that your prime rib soup will need thickening? Well, there are a few easy ways to do that.

My favourite is simply to drain some of the liquid and to put it to one side for another meal or for freezer stock.

The next option is to mash a couple of the potatoes and then mix with your spoon.

Or for a third option for thickening your prime rib soup is to add in extra black beans.

Or if you would like a creamy prime rib soup, a good option is to use a hand blender and with your hand blender, blend about 10% of your soup and stir. This will make a much creamier soup, but still maintain a chunky soup.

    • Hi E Jackson,

      You cannot reheat or freeze this soup because the rib has already been cooked 2 times. It is recommended not to reheat meat more than 2 times to be safe, so you can avoid any issues with the food like food poisoning. I was always taught this whilst working as a chef in many different places, I always give advice based on what I have learnt 🙂

      Hope this helps!
