Why the Instant Pot is Perfect for Soup
The Instant Pot isn’t just a kitchen gadget; it’s a culinary assistant, especially when it comes to hearty soups like this Potato Leek masterpiece. Its pressure cooking function drastically cuts down cooking time, allowing you to achieve slow-cooked flavors in a fraction of the time. This means tender potatoes and perfectly softened leeks without hours of simmering on the stovetop. Moreover, the sauté function lets you build rich flavor directly in the pot, minimizing cleanup by using a single vessel for both sautéing and pressure cooking. The consistent heat and sealed environment ensure even cooking, locking in moisture and nutrients, which results in a deeply flavorful and aromatic soup every time. For busy individuals or families, the Instant Pot makes homemade comfort food accessible and effortless.
Ingredient Notes: Crafting the Perfect Creamy Potato Leek Soup
The beauty of this Instant Pot Potato Leek Soup lies in its simple yet high-quality ingredients. Paying attention to these components will ensure your soup is rich, flavorful, and wonderfully creamy. For exact measurements, please refer to the comprehensive recipe card below.
- Leeks: These mild, onion-like vegetables are the star alongside the potatoes. When preparing leeks, it’s crucial to clean them thoroughly, as dirt often gets trapped between their layers. Focus mainly on the white and light green parts, as the darker green tops can be tough. A simple method is to slice them first, then rinse them well under running water in a colander.
- Butter: Starting your sauté with butter adds a beautiful depth and richness to the soup that oil can’t quite replicate. Its nutty aroma enhances the overall flavor profile. However, if you prefer or need a dairy-free option, good quality olive oil can be used as a substitute.
- Potatoes: The choice of potato significantly impacts the soup’s texture. Russet potatoes, known for their starchiness, will yield a thicker, creamier soup when blended. Yukon Gold potatoes offer a buttery flavor and a lovely creamy texture. Red potatoes provide a slightly waxier texture, maintaining some shape even after blending. I personally don’t peel the potatoes, as the skins blend seamlessly into the soup with an immersion blender, saving you an extra step without compromising on smoothness. If you prefer a completely peel-free soup or are using a potato masher, peeling beforehand is recommended.
- Broth: Both vegetable broth and chicken broth work wonderfully in this recipe. Choose whichever you have on hand or prefer based on dietary preferences. Opting for low-sodium or no-sodium broth gives you complete control over the seasoning, allowing you to salt the soup to your exact liking without it becoming overly salty.
- Milk: For the creamiest and most luxurious potato leek soup, whole milk is highly recommended. Its higher fat content contributes significantly to the rich mouthfeel. 2% milk can also be used, but for optimal flavor and texture, avoiding skim milk is advisable.
- Corn Starch: This acts as a thickening agent, ensuring your soup achieves that perfect, satisfying consistency. It’s crucial to whisk it thoroughly with the milk until completely dissolved before adding it to the hot soup to prevent lumps.
- Sour Cream: A dollop of full-fat sour cream adds a delightful tanginess and an extra layer of creaminess to the soup. This subtle acidity brightens the overall flavor and balances the richness of the potatoes and dairy.
- Cheese: The recipe calls for one cup, but feel free to add more if you’re a cheese enthusiast! For the ultimate melt and creamiest texture, shred your cheese directly from the block. Pre-shredded cheeses are often coated with cellulose to prevent clumping, which can hinder their melting ability and result in a grainier texture in your soup. Sharp cheddar, Gruyere, or even a good quality white cheddar are excellent choices.
How to Make This Instant Pot Potato Leek Soup: Step-by-Step
Creating this flavorful and comforting Instant Pot Potato Leek Soup is a breeze with these easy-to-follow steps. Your pressure cooker will do most of the heavy lifting, allowing you to enjoy a delicious homemade meal in no time.
- Prepare Your Ingredients: Begin by washing and chopping all your vegetables. Dice the potatoes into bite-sized pieces and chop the leeks (white and light green parts) and celery. Remember, leeks can hide a lot of grit, so rinse them thoroughly after chopping to ensure all dirt is removed. Have your garlic minced and your seasonings ready.
- Sauté the Aromatics: Turn your Instant Pot to the “Sauté” setting and allow it to heat up. Once hot, add the butter (or olive oil) and let it melt. Add the chopped leeks and celery to the pot and sauté for about 3-4 minutes, stirring frequently, until they begin to soften and become fragrant. This step is crucial for developing a deep base flavor. Next, add the minced garlic and stir for another minute until aromatic, being careful not to burn it.
- Build the Soup Base: Turn off the Instant Pot’s “Sauté” function. Pour in the broth, using a wooden spoon to scrape up any browned bits from the bottom of the pot – this is called deglazing and adds immense flavor while preventing the “Burn” error. Add the chopped potatoes, parsley, thyme, salt, and pepper. Stir everything well to combine. Ensure the broth mostly covers the potatoes; if not, add a little more broth to ensure they cook evenly.
- Pressure Cook to Perfection: Secure the lid on your Instant Pot, making sure it is properly sealed. Turn the vent to the “Sealing” position. Select the “Pressure Cook” (or “Manual” on older models) setting and set the cooking time for 10 minutes. The Instant Pot will take some time to come to pressure before the 10-minute countdown begins.
- Quick Release and Finish: Once the pressure cooking cycle is complete, carefully perform a quick release by turning the vent to the “Venting” position. Stand clear of the steam as it escapes. When the float valve drops, it’s safe to open the lid.
- Thicken and Cream: In a separate small bowl, whisk together the corn starch and milk until the corn starch is completely dissolved and no lumps remain. Slowly pour this mixture into the Instant Pot, stirring continuously to fully combine it with the hot soup. This will help thicken the soup as it warms.
- Add the Dairy: Next, stir in the heavy cream, cheese, and sour cream. Continue stirring gently until the cheese has fully melted into the soup, creating a velvety texture.
- Achieve Desired Consistency: At this point, you can serve the soup as is for a chunkier texture, or use an immersion blender to achieve a smoother consistency. Blend cautiously and intermittently if you prefer some lovely potato and leek chunks throughout your soup. If you don’t have an immersion blender, you can carefully transfer about half of the soup to a regular blender, blend until smooth, and then return it to the pot.
- Season and Serve: Taste the soup and adjust the seasonings (salt and pepper) to your preference. If the soup is too thick, you can thin it out by adding a splash more broth or milk until it reaches your desired consistency. Ladle into bowls and top with your favorite garnishes!
Notes and Tips for the Best Instant Pot Potato Leek Soup
- Avoid Gummy Potatoes: When blending the soup, whether with an immersion blender or a regular blender, be careful not to over-process the potatoes. Over-blending starchy potatoes can release too much starch, leading to a gummy or gluey texture. A few pulses are usually enough to achieve a creamy consistency while still leaving some delightful chunks, which adds to the rustic charm of this potato leek soup. If you are mashing, consider peeling the potatoes first.
- Immersion Blender Alternatives: No immersion blender? No problem! You can achieve a smooth texture by carefully transferring about half of the cooked soup into a standard blender. Blend until smooth, then pour it back into the pot and stir to combine. Alternatively, a potato masher can be used directly in the pot to break down the potatoes to your desired chunkiness, especially if you prefer not to peel them.
- Customizing Cheese Flavor: The recipe suggests one cup of cheese, which provides a lovely, subtle cheesy note. However, if you adore a bolder, richer cheese flavor in your creamy potato leek soup, feel free to double the amount! Cream-based soups are naturally rich, so starting with a moderate amount of cheese and adding more to your taste is always a good approach.
- Adjusting Soup Thickness: If your soup turns out thicker than desired after adding the dairy and cheese, simply thin it out with additional warm broth or milk, stirring until it reaches your preferred consistency. If it’s too thin, you can make a small slurry with a teaspoon of cornstarch and a tablespoon of cold water, stir it into the simmering soup, and cook for another minute to thicken.
- Enhancing Flavor: For an even deeper flavor, you can roast the leeks and potatoes briefly before adding them to the Instant Pot. This caramelization adds a wonderful layer of complexity to the soup.
What To Top Your Instant Pot Potato Leek Soup With:
Elevate your comforting bowl of potato leek soup with a variety of delicious toppings that add texture, flavor, and visual appeal. Here are some of our favorite garnishes:
- Extra shredded cheese (for the ultimate cheese lovers!)
- Freshly chopped chives or green onions for a delicate oniony bite.
- Crispy bacon bits or crumbled bacon for a smoky, savory crunch.
- Crunchy croutons for added texture.
- A dollop of sour cream or Greek yogurt for extra creaminess and tang.
- Crispy fried onions for a sweet and savory crunch.
- Fresh thyme sprigs for an aromatic finish.
- A sprinkle of Fritos (don’t knock it ’til you try it – trust me on this one!)
How To Make This Creamy Potato Leek Soup in the Crockpot:
No Instant Pot? No problem! You can absolutely still enjoy this incredibly delicious and creamy potato leek soup using your trusty Crockpot or slow cooker. The process is equally simple, just requiring a bit more time. To begin, toss the chopped potatoes, broth, seasonings, leeks, and celery into your slow cooker. For the best depth of flavor, I highly recommend briefly sautéing the leeks and celery in a separate pan with butter or oil before adding them to the Crockpot, mirroring the Instant Pot’s initial step. Cook on low heat for 6-8 hours or on high heat for 3-4 hours, until the potatoes are wonderfully soft and tender. Once cooked, follow the remaining instructions from the recipe card: whisking in the corn starch and milk mixture to thicken, and then stirring in the heavy cream, sour cream, and cheese. Finish with a quick blend to your desired consistency and enjoy!
Storage and Reheating Instructions for Potato Leek Soup:
Proper storage ensures you can enjoy your delicious Instant Pot Potato Leek Soup for days to come. To store any leftovers, allow the soup to cool completely to room temperature first. Then, transfer it to an airtight container and refrigerate for up to 5 days. Potato leek soup can also be frozen, which makes it an excellent meal prep option. Again, ensure it is completely cooled before transferring to freezer-safe containers or bags. It will keep well in the freezer for up to 3 months.
When you’re ready to reheat, there are a couple of easy methods. For microwave reheating, transfer a single serving to a microwave-safe bowl and heat in 1-minute increments, stirring in between, until thoroughly warmed through. If the soup appears too thick after refrigeration or freezing, add a splash of extra milk or broth to thin it out to your desired consistency. For stovetop reheating, gently heat the soup on medium-low heat in a pot, stirring frequently, until it just begins to lightly bubble. Avoid boiling to maintain the soup’s creamy texture.

Print Recipe
Ingredients
- 3 lb potatoes, cut into bite sized pieces
- 2 large leeks, whites only, roughly chopped
- 4 celery stalks, chopped
- 2-3 garlic cloves, minced
- 1 ½ T butter (or olive oil)
- 4 c broth, more as desired
- ½ tsp thyme
- 1 tsp parsley
- ¾ tsp pepper
- ½ tsp salt
- 3 T corn starch
- 1½ c milk
- 1 c shredded cheese (e.g., sharp cheddar, Gruyere)
- ½ c sour cream
- ½ c heavy cream
Instructions
-
Chop all vegetables and prep ingredients. Turn your Instant Pot to “Sauté” and allow it to heat up. Melt butter. Add in leeks and celery and heat for about 3-4 minutes or until slightly softened. Add in garlic and stir, heating for another minute until fragrant.
-
Turn off the Instant Pot. Add in broth, scraping any browned bits off the bottom of the pot. Add the potatoes, parsley, thyme, salt and pepper. Stir to combine thoroughly.
-
Close and lock the Instant Pot lid. Ensure the vent is turned to “Sealing” and set it to pressure cook for 10 minutes. When the cycle is complete, perform a quick release to allow pressure to escape. Carefully remove the lid once the float valve drops. In a small bowl, whisk together the milk and corn starch until dissolved.
-
Slowly pour the milk and corn starch mixture into the soup, stirring continuously to combine and thicken. Stir in the heavy cream, sour cream, and shredded cheese until the cheese is completely melted.
-
Use an immersion blender to blend the soup to your desired consistency – slightly blended for chunky soup, or more thoroughly for a smoother texture. You can also transfer half the soup to a regular blender for this step. Adjust seasoning to taste. Serve with your favorite toppings. Store leftovers in an airtight container in the refrigerator for up to 4-5 days.
Notes
- You can use olive oil instead of butter in this potato soup if you prefer; both will work just fine.
- If you don’t have an immersion blender, you can pour half of the soup into a standard blender and blend until smooth. Then pour it back into the pot and stir to combine.
- The amount of cheese can be adjusted to your preference. While cream-based soups can be rich, feel free to add more than one cup if you desire a stronger cheesy flavor.
