Remember the pressure cookers of old that would splutter and rock, and make all sorts of scary noises? None of that with the Instant Pot. Just set the time, close the lid and let it do it’s thing. It even keeps your food warm once it’s finished cooking! How good is that?

Can you cook this Ham, Leek and Potato Soup any other way?

We used the slow cooker function on the Instant Pot for this recipe, but you could also use the pressure cooker function or just a pan on the stove. 

The pressure cooker should only take around 8-10 minutes cooking time, plus about 15 minutes natural pressure release, whilst the stove top version will take about half an hour to 45 minutes.

  1. First sauté the leeks in a few sprays of Frylight, then add them to the slow cooker. If you use an Instant Pot set it to sauté
  2. When the leeks start to soften add the ham and the potatoes
  3. Top up with the stock
  4. Set to slow cook for 4 hours, or until the ham is tender and the potatoes soft
  5. When everything is cooked if you want the soup a bit thicker roughly mash up some of the potato, with a potato masher, just enough to thicken the soup slightly, then cook for another 30 minutes or so

  1. Hi,

    I have a soup maker. If I cut the gammon into slightly smaller chunks do you think it’d still work? I think the standard setting takes 20-25 mins to cook.

  2. Going to try this very soon. Tempted to add a can of butter beans too (not that the recipe needs it I just love them) would be lush half mashed with the potatoes at the end. Thanks for another winner 🙂

  3. I made this today in my slow cooker for 12 hours on low but the potatoes werent cooked well. I used jacket potatoes.
    Unsmoked gammon joint isn’t too salty.
    All in all a lovely soup.

  4. This soup looks amazing and I want to cook it, only my pressure cooker isn’t an instant pot and doesn’t have a slow cooker mode. Would you recommend that I just cook it in my slow cooker or could this still be made in the pressure cooker, on the soup setting or meat setting and if so how many min on which setting please?
