Why You’ll Love It

• 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.
• We love how creamy and velvety this soup is. The high-pressure of the Instant Pot allows the ingredients to meld together beautifully, resulting in a luscious soup without the need for excessive cream or butter.

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

Equipment Needed

• Instant Pot – I use a 6-quart Instant Pot Duo Plus to make all of my recipes, but you can use any size or brand of electric pressure cooker. If you’re using an 8-quart pot, you will need to adjust the amount of liquid accordingly, as it requires more water to build steam.
• Immersion blender – This is a very handy kitchen tool to have around. If you don’t have one you can always use a blender. Just be careful, hot liquid can explode in the blender.

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.
•  If you use a low-sodium broth, you may need to add additional salt to taste.
• 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!)

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.

Step 1: Cut up the Vegetables

Start by washing the leeks thoroughly, as they can often harbor dirt and sand between their layers. Cut off the dark green tops and the root end, leaving the tender white and light green parts. Slice the leeks into rounds.

For the potatoes, peel and dice them into uniform pieces to ensure they all cook evenly.

Step 2: Sauté the Leeks

Turn on Sauté mode on the Instant Pot. Melt the butter in the pot. Add the leeks. Sauté for 3-5 minutes, just to soften the leeks, not brown them. Turn off sauté mode after 5 minutes (any longer and it might get too hot). Add the salt, pepper and garlic.

Step 3: Pressure Cook

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.

Step 4: Puree the Soup

Using an immersion blender, puree the soup to a smooth texture. Turn on sauté mode 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. If you don’t have one, check out our guide on which one to buy. Also see our guide to How to Use an Instant Pot and the many accessories you can buy for it.

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

Reheating leftover potato leek soup is a breeze, and you have a few options to choose from depending on your time and preference.

Stovetop – Gently warm the soup in a pot over low to medium heat. Stirring occasionally, allow it to come up to temperature.

Instant Pot – Simply place your soup in the Instant Pot, lock the lid, and select the “High Pressure” setting for 5 minutes. After a quick release of pressure, your soup will be piping hot and ready to serve.

Microwave – Place it in a microwave-safe container, cover it, and heat on medium-high power for 3-5 minutes. Be sure to pause and stir the soup at intervals to ensure even heating.
