Gathering the right ingredients is key, and this recipe keeps it delightfully simple. Each component plays a vital role, whether it’s the sweetness of the leeks, the creaminess from the potatoes, or the aromatic hint from fresh herbs that rounds out the flavor profile.

Leeks (white and light green parts only): They bring a subtle oniony sweetness that’s the soul of this soup.
Butter: Adds richness and a silky texture during sautéing.
Garlic (minced): Provides a fragrant depth without overpowering the delicate flavors.
Russet or Yukon Gold potatoes (1-inch pieces): These give the soup its creamy body and smooth mouthfeel once pureed.
Fresh thyme sprigs: Adds a fresh herbal note that complements the earthiness of the potatoes.
Bay leaf: Infuses the broth with subtle complexity during cooking.
Salt and black pepper: Essential seasoning to enhance all the natural flavors.
Low sodium vegetable or chicken broth: The flavorful base that ties everything together, also controls soup consistency.
Chopped fresh chives (for garnish): Adds a bright, oniony contrast and a pop of vibrant color on top.

How to Make Instant Pot Potato Leek Soup Recipe

Step 1: Prepare the leeks

Start by trimming the leeks to use only the white and light green parts, then slice them into thin half moons. Washing them thoroughly is crucial since leeks often hold grit between their layers. A good soak and drain in cool water ensures your soup will be silky, not sandy.

Step 2: Sauté the leeks and garlic

Switch your Instant Pot to sauté mode, melt the butter, then add the chopped leeks. Cooking them until softened takes about 4 to 5 minutes, which brings out their natural sweetness. Stir in the minced garlic for just 30 seconds so it releases aroma without burning, then turn off the sauté function.

Step 3: Deglaze with broth

Pour in a cup of your broth, then scrape the bottom of the pot to lift any caramelized bits. This step is not just about cleaning the pot; it incorporates those flavorful browned bits back into the soup, deepening the taste.

Step 4: Add potatoes and herbs

Now it’s time to add the potatoes, thyme sprigs, bay leaf, salt, pepper, and the remaining broth. Give everything a good stir to combine all the elements, ensuring the potatoes are submerged to cook evenly.

Step 5: Pressure cook the soup

Secure the lid and set the steam release valve to sealing. Use the Pressure Cook or Manual function to cook at high pressure for 8 minutes. The Instant Pot will take about 15 minutes to reach pressure before the countdown begins, which allows the flavors to meld beautifully.

Step 6: Release pressure and finish

Once the cooking time ends, let the pressure release naturally for 10 minutes. This gentle release helps the potatoes continue to soften delicately. Afterward, carefully quick release any remaining pressure before opening the lid.

Step 7: Remove herbs and puree

Take out the bay leaf and thyme stems, which have done their job infusing flavor. Use an immersion blender directly in the pot to puree the soup until smooth and silky. If you prefer, transfer the soup in batches to a blender for a perfectly velvety texture.

Step 8: Taste and adjust

Give your soup a taste and season with additional salt or pepper if needed. If it feels too thick, stir in a little more broth until you reach your perfect consistency. Garnish with freshly chopped chives before serving.

Garnishes

The chopped fresh chives on top are not just pretty—they add a refreshing brightness that cuts through the creamy richness of the soup. You can also try a swirl of cream or a sprinkle of crispy bacon bits for an extra pop of indulgence.

Side Dishes

This soup pairs beautifully with crusty bread like a baguette or a slice of sourdough, perfect for dipping. A crisp green salad or some roasted vegetables on the side will round out your meal with vibrant textures and freshness.

Creative Ways to Present

Serve your soup in rustic bowls for a cozy feel or elegant white soup plates for a special occasion. Add edible flowers or a drizzle of herb oil on top to elevate the presentation and impress your guests visually as well as with flavor.

Make Ahead and Storage

Storing Leftovers

Leftover soup should be cooled to room temperature and stored in an airtight container. It keeps well in the refrigerator for up to 3 days, making it a wonderful option for quick lunches or dinners during a busy week.

Freezing

This soup freezes beautifully. Portion it into freezer-safe containers or bags, leaving some headspace as it will expand. Frozen soup lasts for about 2 months, so you’ll have homemade comfort ready whenever you need it.

Reheating

Thaw frozen soup overnight in the refrigerator for best results. Reheat gently on the stovetop over medium-low heat, stirring occasionally until warmed through. If the soup is too thick, add a splash of broth or water to loosen it to your liking.

FAQs

Can I use other types of potatoes for this soup?

Absolutely! Russet and Yukon Gold are ideal for their creamy texture, but red potatoes or fingerlings can work as well. Just keep in mind that waxy potatoes tend to keep more structure and won’t puree as smoothly.

Is it necessary to peel the potatoes?

If you’re using Russet potatoes, peeling is recommended for the smoothest texture. Yukon Gold potatoes have thin skin that softens when cooked, so you can leave the peel on if you prefer added nutrition and texture.

Can I make this soup vegan?

Yes! Swap the butter for olive oil or a plant-based margarine and use vegetable broth instead of chicken broth. The creamy texture and flavor will still shine through beautifully.

How can I make the soup thicker or thinner?

For a thicker soup, use less broth or cook it a bit longer uncovered to reduce. To thin it out, simply add more broth or water and reheat until you reach your desired consistency.

Can I prepare the soup without an Instant Pot?

You can! Sauté the leeks and garlic in a large pot, add broth, potatoes, and herbs, then simmer gently until potatoes are tender, about 30–40 minutes. Puree and season as directed. The Instant Pot just speeds up the process wonderfully.
