The Versatile Pressure Cooker Potato Leek Soup Recipe

While often associated with specific brands like Ninja Foodi or Instant Pot, this potato leek soup recipe is incredibly adaptable to *any* pressure cooker you might have on your kitchen counter. From Mealthy to Crockpot Express, as long as your appliance boasts a high-pressure function, you’re fully equipped to whip up this flavorful soup. We frequently develop easy Ninja Foodi recipes, and this one is a shining example of pressure cooker simplicity at its best.

If you prefer to keep your meal light and healthy, or if you’re aiming for a delicious vegetarian soup, feel free to omit the bacon entirely. The choice of potatoes also offers customization – while Russets are often lauded for their ideal texture in creamy soups, Yukon Golds or even red potatoes can be used, each imparting a slightly different character to the final dish.

What is a Leek and How to Prepare It?

If you’re new to this elegant, chive-looking vegetable, you’re in for a treat! A leek is a member of the Allium family, closely related to onions, garlic, and shallots. However, it boasts a distinctly milder, sweeter onion flavor, making it a favorite for its delicate taste in a wide array of culinary dishes. Leeks typically grow to about 12 inches in length and are commonly diced into small pieces for recipes, where they add a subtle aromatic depth without overpowering other ingredients.

Perhaps you’re wondering if you’ll enjoy its unique flavor. Let’s explore everything you need to know about leeks to ensure you get the most out of this delightful ingredient:

Frequently Asked Questions About Leeks:

Does a leek taste like an onion?

Leeks offer a flavor profile that is indeed similar to an onion but with a notable sweetness and far less pungency. Being in the same family as onions, garlic, and shallots, their taste can be described as a gentle blend of all three. When consumed raw, leeks can be quite strong and crunchy, but cooking them, especially in a pressure cooker or Ninja Foodi soup, transforms their character. They soften beautifully, and their flavor mellows significantly, becoming a delicate, harmonious complement to the other ingredients in your dish.

What part of the leek do you eat?

When preparing leeks, you typically use only the white and light green parts of the stalk. Think of it much like a stalk of celery. The darkest green leaves at the very top are usually tough and fibrous, so you will cut off and discard the top two-thirds to three-quarters of the leek. The desirable sections are the white and pale green or yellowish parts at the bottom, which are tender and flavorful, perfect for dicing and incorporating into your recipes.

While raw leeks can be strong and crunchy, making them less of a favorite for some, their transformation when cooked is remarkable. In the Instant Pot, they become incredibly tender and develop a light, nuanced flavor that perfectly complements potatoes and other ingredients, enriching the soup without dominating it.

Essential Ingredients for Potato Leek Soup

Crafting this delicious soup requires only a handful of fresh, simple ingredients. Here’s what you’ll need:

• 3 medium to large leeks, carefully cleaned and diced.
• 4 medium potatoes (Russet or Yukon Gold recommended), peeled and chopped into uniform pieces.
• 1/2 a white onion, diced.
• 2 tablespoons butter, or a plant-based alternative for a dairy-free version.
• 1 teaspoon minced garlic.
• 3 cups chicken broth, or vegetable broth for a vegetarian option.
• 2 teaspoons Herbes de Provence, or your preferred seasoning blend.
• 1 cup heavy cream, for that signature creamy texture.

Regarding the liquid, while chicken broth adds depth, you certainly have options. Vegetable broth is an excellent choice for a robust vegetarian or vegan soup base. Even plain water can be used in a pinch, though broth significantly elevates the flavor. For those seeking an even richer, more nourishing soup, consider using Instant Pot bone broth. The choice ultimately depends on your taste preferences and dietary considerations, allowing you to tailor the soup to your exact liking.

Customizing Your Potato Leek Soup: Add-Ins and Variations

With Bacon: A Savory Addition

If you’re a fan of rich, savory flavors and wish to incorporate meat into your soup, crispy bacon is an outstanding choice. To add bacon, begin by dicing it into small, bite-sized pieces. Use the sauté function on your Instant Pot, adding a touch of olive oil if needed, and cook the bacon until it’s browned and slightly crispy, but not overly crunchy. Once cooked, remove the bacon to a paper towel-lined plate, leaving a small amount of rendered fat in the pot. Turn off the sauté function, and proceed to deglaze the pot with a splash of broth before adding your vegetables. The rendered bacon fat will infuse a wonderful smoky depth into the soup. After the soup is blended, you can stir in the cooked bacon pieces or use them as a delightful garnish. This method also works wonderfully for using up leftover ham after the holidays, adding a similar savory element.

Vegetarian and Vegan Options

For a completely meatless soup, simply omit the bacon or any other meat. This recipe shines beautifully on its own as a hearty vegetarian dish. To further enhance the vegetable profile, consider adding other inexpensive yet flavorful ingredients. Diced celery, for example, is a fantastic addition, providing extra flavor and a subtle textural contrast. Approximately 1 cup of finely diced celery, added with the leeks and onions, is an excellent choice. Opt for tender celery stalks for the best results. Other vegetables like finely chopped carrots or even a handful of frozen broccoli florets can also be added during the pressure cooking phase to boost nutrition and flavor.

How to Make Dairy-Free Potato Leek Soup

Achieving that luscious, creamy texture without dairy is surprisingly simple. Instead of heavy cream, you can use a lactose-free dairy alternative. Unsweetened almond milk, cashew milk, or even full-fat coconut milk (for a slightly different flavor profile) are great choices. To ensure your dairy-free soup still has a desirable thickness, whisk 1-2 tablespoons of cornstarch into your chosen dairy alternative before stirring it into the soup at the end. This slurry will help thicken the soup to perfection. This technique of using a thickening agent in alternative milks is also similar to how you might make buttermilk with lemon juice by curdling the milk.

Best Potatoes to Use for Creamy Soup

The choice of potato plays a crucial role in the final texture of your soup. With so many varieties available, understanding their characteristics can help you achieve your desired creaminess. The primary differences lie in their starch content and how they break down when cooked.

For a truly creamy, smooth soup like this potato leek recipe, **Russet potatoes** or **Yukon Gold potatoes** are your best bet. Russets are high in starch, which allows them to break down easily and contribute to a thick, velvety texture when blended. Yukon Golds are also starchy but have a naturally buttery flavor and a slightly finer texture that blends beautifully. On the other hand, waxy potatoes like red potatoes or new potatoes tend to hold their shape more, resulting in a firmer texture even after cooking for longer periods. If you prefer a chunkier soup, these could work, but for a smooth, pureed consistency, stick with Russets or Yukon Golds.

While leaving the skins on potatoes can add extra fiber and nutrients, for the silkiest soup texture you envision, it’s highly recommended to peel all the potatoes at the beginning. The skins, even after blending, can leave a slightly grainy texture. Remember, the smaller and more uniformly you chop your potato pieces, the faster and more evenly they will cook in the pressure cooker.

Before you even fire up your Instant Pot, the key to a smooth cooking process is preparation. Begin by thoroughly prepping all your vegetables. From start to finish, including prep time and pressure cooking, this recipe will take you approximately 30-40 minutes (with only 15 minutes of active cooking once the Instant Pot is sealed). Keep this in mind during your meal planning. If you’re planning to serve this comforting soup with a side of our delicious pull-apart bread with biscuits, consider popping that into the oven at the very beginning of your soup making process. That way, both elements will be perfectly ready to enjoy together, creating a truly harmonious and satisfying meal.

How to Make Instant Pot Potato Leek Soup: Step-by-Step

• Prepare the Leeks: Start by trimming and discarding the tough, dark green parts of the leeks. Slice the remaining white and light green sections lengthwise, then cut them into small, manageable pieces. Place the chopped leeks in a large bowl of water and swish them around thoroughly to remove any hidden dirt or grit. Drain well.
• Prep Potatoes: Peel your chosen potatoes (Russet or Yukon Gold for best results) and chop them into uniform 1.5×1.5-inch cubes.
• Sauté Aromatics: Turn on your Instant Pot’s “Sauté” function. Add the butter (or vegan plant-based sticks) to the inner pot. Once melted, add the chopped leeks, diced white onion, and minced garlic. Sauté, stirring occasionally, until the vegetables have softened and become fragrant, about 5-7 minutes. If adding bacon, you would cook it with the butter at this stage before adding other aromatics. Once softened, turn off the “Sauté” function.
• Combine Ingredients: Add the chopped potatoes, chicken or vegetable broth, and Herbes de Provence to the pot. If you enjoy a subtle herbal note, you can also toss in a bay leaf at this point (remember to remove it before blending).
• Pressure Cook: Secure the lid on your Instant Pot, making sure the sealing vent is in the “Sealing” position. Select the “Pressure Cook” or “Manual” setting on High Pressure and set the cooking time for 8 minutes.
• Natural Pressure Release: Once the cooking time is complete, allow the pressure to release naturally (NPR) for at least 10-15 minutes. This natural release helps prevent foaming and ensures the soup’s flavors fully meld. After natural release, you can carefully turn the venting knob to the “Venting” position to release any remaining pressure.
• Add Cream & Blend: Carefully open the lid. Stir in the heavy cream (or your dairy-free alternative). For a wonderfully smooth soup, use an immersion blender directly in the pot to blend the soup until it reaches your desired consistency. Alternatively, carefully transfer batches of the soup to a standard blender, blending until smooth, then return to the pot.
• Garnish & Serve: Taste the soup and season with salt and freshly ground black pepper to your preference. Everyone has their own ideal seasoning level, so it’s often best to adjust at the very end. Garnish with fresh chopped chives or parsley, if desired, for a pop of color and freshness.

This potato leek soup truly defines comfort food, perfect for a cold evening, or surprisingly, even during warmer months when you want a delicious meal without heating up your entire kitchen with the oven or stovetop. Its simple elegance and robust flavor make it a year-round favorite!
