Instant Pot Potato Soup

For some reason I don’t take advantage of my Instant Pot as much as I should.  This Instant Pot Potato Soup was so easy and delicious!  And as of December 2024 with the new Weight Watchers change, its ZERO POINTS!  Whoop!  Add a touch of extra cheese and bacon bits on top.

Sunday night I normally go through my pantry/fridge and freezer to see what needs to be used up.  Happy to report that the 5 pound bag of carrots I thought was a good idea to buy from Costco a couple weeks ago is now completely used – go me!

Side note – I am not exactly sure that the saute part of this recipe is necessary, but that’s how I made it so I am going with it.

Ingredients Needed:

  • potatoes (I used Idaho but russets work great!)
  • carrots
  • celery
  • vegetable broth
  • chicken base (like Better Than Bouillion)
  • cajun seasoning (if you like a bit of spice)
  • unsweetened almond milk
  • corn starch
  • salt and pepper

How long do you cook potato soup in the Instant Pot?

For me, I wanted to be able to mash the soup with a potato masher after cooking, so I cooked on high pressure for 35 minutes.  All the vegetables were cooked to fork tender, and the soup was easy to mash to get it both creamy and a bit chunky at the same time if that makes sense?

This soup has half a pound of celery, and you can really taste the celery, which I love.  So reduce the amount if you don’t want an overly “celery” tasting potato soup.  I also added a lot of garlic cloves, so you add as much or as little as you like.

After the initial 35 minutes, the soup is nearly done – just need to add the cornstarch/almond milk slurry and cook an additional 5 minutes.

What if I don’t have an instant pot?

Simply cook in a large stock pot with a lid.  Follow the instructions above, but simmer over medium low heat for 35 minutes, or until the veggies are fork tender.  Then add the cornstarch/almond milk slurry and cook and additional 5 minutes.  If you dice your veggies small enough, they should cook in 35 minutes.
