Instant Pot Potato Leek Soup
This Instant Pot Potato Leek Soup is so delicious. With only a few ingredients, it can easily made vegan because it has no cream.

This is a hearty thick soup that you can make into a meal with a piece of bread for dunking and a nice salad. Of course, you could thin it out if you are looking for a lighter soup.
Did you know that traditional potato soup actually did not have any heavy cream in it? Nope. So if you swap out the butter with a vegan alternative, then it is 100% vegan, gluten free and dairy-free.
Making it in your Instant Pot could not be easier and only takes a few minutes, so you could easily make it when you get home from work!
What are leeks?
Leeks are in the same family as onions and scallions (Allium). Leeks are their larger cousin and are grown in very deep soil. More soil is added to the top as they grow to make them more tender.
The only parts of the leek you want to eat are the white and light green parts. These were under ground. The dark green or bluish green tops were above ground and will be tough.
Since leeks are grown under ground they get very dirty inside as the grow. Therefore, you need to wash them carefully to lose any grit.

How to wash leeks
To remove all of the soil from the leeks, cut off top dark tips and root end. Slice leek in half lengthwise. Then slice crosswise into ½ inch thick slices.
Now soak the slices for about 5 minutes in cold water. Use your hands to move the slices so that any stubborn particles are loosened from leeks. I use my salad spinner.
Dump the water they soaked in and then rinse with cold water with the sprayer attachment for your faucet, if you have one. If not then just rinse them very well.
Either place the washed slices in a colander to drain or use a salad spinner to remove the excess water from them. Now you are all set to cook with them.

Can you freeze potato leek soup?
Absolutely. This soup freezes very well and will stay fresh for 4-6 months.
Pro tips for making this soup
- If you are using a thin skinned potato, like Yukon gold, there is no need to peel. If you’re using a thick skinned potato, like Russet potatoes, you should peel them.
- If you don’t peel them your immersion blender will collect a lot of the skins. Some will be blended in.
- Start with a little salt and then taste and adjust your seasonings after the soup is blended.
- Use fresh thyme, if you have it. You can just add a sprig of thyme and then remove it before blending, or remove the tiny leaves from the stems and add them.
- If you would like to thin the soup out, add more vegetable stock and mix it in well.
- If you would like to make a chunky potato soup, chop the potatoes into bite sized pieces. Then before blending, remove some of the chunks. Blend soup, add the whole chunks back in.
