This Instant Pot Potato Leek Soup is quick and easy to make and turns out creamy and flavorful – a great way to utilize the winter bounty of leeks and potatoes.
» The Instant Pot makes wonderful soups & stews. Try this caramelized carrot soup or this easy borscht recipe.

I love making soup in the Instant Pot because the pressure enables the rapid transformation and melding of flavors that you usually can only achieve with hours of simmering on the stovetop.
While Potato Leek Soup doesn’t need a ton of time for the flavors to develop, you’re going to get a really flavorful and delicious soup in just 10 minutes with the Instant Pot, and it would take at least 40 minutes for the potatoes to cook on the stovetop. So it’s a huge time saver. We also use this method with Beet Soup (Borscht) with great success.

Now you can control your pot wirelessly through an app. Cool-touch handles on the pot itself, and an automatic locking pressure release valve for greater safety. This one does it all.
Ingredients You Need
- Butter – you can use ghee, unsalted, or salted butter, as you wish
- Leeks – Remove the tough greens at the top and chop only the light colored, more tender stem
- Potatoes – I use russet potatoes and I peel them before cubing. Peeling does remove some of the nutrients from the potato, but this soup is really best without peels.
- Seasonings: salt, ground black pepper, garlic, thyme, bay leaf
- Vegetable or chicken broth
- Cream or half and half – This is optional. The soup is really creamy on its own, without the cream.
- For garnish: bacon, green onion, and paprika
How to Make Instant Pot Potato Leek Soup
This soup takes just 15 minutes to make, but there will also be some time needed to bring the Instant Pot up to temperature. You can cut down on that time by adding hot chicken stock, rather than cold. This will allow the Instant Pot to pressurize faster.
- Turn on Saute mode on the Instant Pot. Melt the butter in the pot. Add the leeks. Saute for 3-5 minutes, just to soften the leeks, not brown them. Turn off saute mode after 5 minutes (any longer and it might get too hot). Add the salt, pepper and garlic.
- Add the potatoes, broth, thyme and bay leaf. Secure the lid and set to cook for 6 minutes on high pressure. Do a quick pressure release.
- Remove the thyme sprig and bay leaf.
- Using an immersion blender, puree the soup to a smooth texture. Return to a low heat and add the cream. Heat through before serving.

Why Use An Instant Pot?
The Instant Pot is one of the most useful kitchen appliances you can buy, because it drastically cuts down on the cooking time for developing flavors in soups and stews, getting tough cuts of meat tender, and even baking a cheesecake. And there are many accessories that will help you get more out of your Instant Pot.
If you don’t have one yet, check out our guide on which one to buy. Also see our guide to How to Use an Instant Pot for more information.

Tips & Notes for Making Potato Leek Soup
- It’s possible to make this soup vegetarian or vegan, by substituting the butter for olive oil, using vegetable broth, and omitting the cream.
- The soup is really creamy on its own and doesn’t necessarily need the added cream. If you want to save the calories, you can choose not to add the cream at all. If you love a creamy soup, add up to 1/2 cup to suit your taste.
- The immersion blender is the easiest way to blend this soup. Blending for 3-5 minutes will yield a super silky soup. If you don’t have an immersion blender, you can puree the soup in a blender (leaving the vent whole open at the top because the soup is hot!)

Can You Freeze Potato Leek Soup?
Yes, you can freeze this soup, but you want to freeze it before you add the cream, if you’re planning to. The cream can congeal when frozen and it won’t reincorporate into the soup when it’s defrosted. So omit the cream and you can add it in after you’ve reheated the soup, if you want to.
The soup will keep in the refrigerator for up to one week. If frozen, it will keep for a month or longer in the freezer.
How to Reheat it?
To reheat it, slowly bring it up to temperature in a pot on the stovetop, cook for 5 minutes on high pressure in the Instant Pot, or microwave for 3-5 minutes.

Can you freeze this soup?
Hi Carol, you absolutely can freeze this soup. We suggest freezing it before you add the cream. You can freeze it after you add cream but the texture upon reheating might not be as creamy.
Try adding a chopped onion and a handful of Brussels sprouts. Then use your immersion blender while still in the pot. Wonderful!
