Instant Pot Leek and Potato Soup

This leek and potato soup is so simple and rustic, yet it is so flavorful and comforting.

Instant Pot Leek and Potato Soup

With chunky vegetables and a garlicky broth, this soup is the perfect starter for dinner. You could also serve it for lunch with salad and crusty bread. It's both light and hearty at the same time.

This leek and potato soup is a take on porrusalda, a soup from Spain's Basque region. In fact, porrusalda means leek soup in Basque.

While the traditional leek and potato Spanish soup is simmered for two to three hours, you can achieve that same creamy texture by preparing it in an Instant Pot (affiliate link) in just 3 minutes of sautéing and then just 3 minutes of pressure cooking (not including the time it takes to reach pressure)! It's pretty much miraculous!

If you haven't tried leeks in soups, be sure to try leek and celery root soup too. 

How to prepare this soup in an Instant Pot. 

While Instant Pots (or other electric multi-cookers) are primarily electric pressure cookers, you can also sauté in them, which makes it so easy to cut down on extra pots and pans. Plus, they also have a slow cooker function as well as a yogurt function, which I hear is great for proofing dough (I haven't tried it yet).

To make this soup, you sauté the leeks in the multi-cooker, add all of the rest of the ingredients, set it to pressure cook, and then set the cooking time to 3 minutes. The Instant Pot will take about 10 minutes to come to pressure, at which time the 3 minutes start.

Once the 3 minutes are up, you manually release the pressure. Be sure to read the instructions that come with your machine to prevent burns. I also like to lightly cover the release valve with a dish towel to absorb and diffuse the steam as it is expelled from the pressure cooker.

Tips for making this pressure cooker porrusalda:

You can either peel the Yukon gold potatoes or leave them unpeeled, as I did. Either way is fine. You can also cut the potatoes into chunks, or, if you want to be more Basque-like, you can break the potatoes into irregular chunks to release more starch. Just cut them part way, and then break them with your hands.

Be sure to wash the leeks thoroughly before sautéing them. I like to add them to a salad spinner filled with water after slicing them. Just swirl them with your hand, drain, and spin. You can also do this with a bowl of water and a strainer.

To keep this dish vegetarian, you can substitute vegetable stock for the chicken stock. If you want to be totally luxurious, shrimp stock would be amazing in this soup.

For a creamier soup, smash some of the potatoes with a wooden spoon or granny fork after cooking.

In Spain, they often add bits of salt cod when serving this soup. Salt cod is not easy to find here, so I added a few bits of leftover poached cod.

This soup is delicious the day it is made and it also makes delicious leftovers. It gets even creamier over time as the potato starches are released into the broth.

To serve this soup, drizzle it with a little bit of olive oil and a shake of crushed red pepper or a dash of hot sauce.
