Potatoes often get an unfair reputation, largely thanks to their fried counterparts. However, when prepared healthily, they are nutritional powerhouses. They are naturally high in fiber, incredibly low in fat, and packed with essential vitamins, minerals, and potent disease-fighting antioxidants. This makes them a fantastic foundation for a healthy, satisfying meal that supports your well-being.

Essential Ingredients for the Perfect Potato Leek Soup
The beauty of this vegan potato leek soup lies in its simplicity, relying on a handful of basic yet flavorful ingredients to create a truly memorable dish. Each component plays a crucial role in building the soup’s rich taste and luxurious texture.
- **Olive Oil:** We begin by sautéing our aromatics in a good quality olive oil. Its rich, fruity notes complement the other ingredients beautifully, adding depth to the soup’s base. Beyond flavor, olive oil is known for its heart-healthy monounsaturated fats. If olive oil isn’t your preference, any neutral oil suitable for sautéing, such as avocado oil or grapeseed oil, will work well. For those not adhering to a strict vegan diet, a touch of butter or ghee can be substituted for an extra layer of richness, though it’s certainly not necessary for a flavorful result.
- **Leeks & Garlic:** These two ingredients form the aromatic heart of our soup. Leeks, often mistaken for giant green onions, possess a distinctively milder, sweeter, and more delicate onion-like flavor. They soften beautifully when cooked, releasing a gentle sweetness that is absolutely perfect for creamy soups and dips. Don’t have leeks on hand? Don’t fret! A large yellow or white onion can serve as a suitable substitute, or you can explore my comprehensive guide on the Best Substitutes for Leeks for more options. Minced garlic adds a pungent, savory kick that elevates the overall flavor profile, creating a balanced and inviting aroma.
- **Russet Potatoes:** The star of the show! Russet potatoes are an excellent choice for this soup due to their high starch content. As they cook, they break down readily, naturally thickening the soup and contributing to its incredibly creamy texture without the need for any dairy. If you desire an exceptionally smooth soup, peeling the potatoes before cooking is recommended. However, for a more rustic feel and an extra boost of fiber, you can leave the skin on. While russets are ideal, yellow or gold potatoes (such as Yukon Golds) are also fantastic alternatives, offering a slightly waxier texture but still blending into a delightful creaminess.
- **Vegetable Broth:** This is more than just a liquid base; it’s a foundational flavor enhancer. A good quality vegetable broth adds an instant layer of savory depth to the soup. To manage sodium intake, I highly recommend opting for a reduced-sodium vegetable broth. This allows you to control the seasoning precisely, adding salt to taste without making the soup overly salty.
- **Thyme & Bay Leaf:** These classic herbs are the secret to the soup’s warm, earthy, and subtle flavor profile. Dried thyme imparts a gentle, aromatic essence that pairs wonderfully with potatoes and leeks. A single bay leaf, simmered with the other ingredients, releases a nuanced, almost floral note that deepens the soup’s complexity. Remember to remove the bay leaf before blending, as it’s meant to infuse flavor, not to be consumed.

Step-by-Step Instant Pot Potato Leek Soup Recipe
Creating this delicious vegan potato leek soup in your Instant Pot is incredibly straightforward. Follow these simple steps for a warm, comforting meal that’s ready in no time.
Step One: Sauté the Aromatics
Begin by pressing the “Sauté” button on your Instant Pot. Allow it to heat up for a few minutes, then drizzle in the olive oil. Once the oil is shimmering, add your chopped leeks and minced garlic to the pot. Cook them for about 3-5 minutes, stirring occasionally, until they soften and become fragrant. This step is crucial for building the soup’s foundational flavor. For detailed ingredient quantities, refer to the recipe card below.
Step Two: Add Remaining Ingredients
After the leeks and garlic have softened, press the “Cancel” button on your Instant Pot to turn off the sauté function. Carefully add the quartered russet potatoes, vegetable broth, water, dried thyme, and the bay leaf into the pot. Ensure all ingredients are submerged in the liquid.
Step Three: Pressure Cook
Secure the lid on your Instant Pot, ensuring it is properly locked. Set the pressure cooking time to 6 minutes on high pressure. Once the cooking cycle is complete, allow the pressure to release naturally (NPR) for 5-10 minutes. This natural release helps prevent foaming and allows the flavors to meld beautifully. After the natural release, carefully perform a quick release (QR) to vent any remaining pressure.
Step Four: Remove Bay Leaf
Once all the pressure has been released and the float valve has dropped, you can safely remove the lid. Using tongs, carefully locate and remove the bay leaf from the soup. Discard the bay leaf, as its purpose of infusing flavor is now complete.
Step Five: Blend and Serve
With the bay leaf removed, carefully use a hand immersion blender directly in the pot to blend the soft potatoes and leeks into a smooth, creamy soup. Blend until your desired consistency is achieved – whether you prefer it velvety smooth or with a few small chunks for texture. If you don’t have an immersion blender, carefully transfer batches of the soup to a regular blender (see tips below). Serve the soup hot, garnished with fresh chives for a burst of color and a mild oniony zest. Enjoy your homemade, incredibly satisfying vegan potato leek soup!
Expert Tips for a Flawless Vegan Potato Leek Soup
Achieving the perfect bowl of vegan potato leek soup is easy with these helpful tips and tricks. Whether you’re adapting to stovetop cooking or looking for ingredient alternatives, these insights will ensure your soup is always a success.
- **Stovetop Cooking Method (No Instant Pot? No Problem!):** If you don’t own an Instant Pot, you can absolutely make this recipe on the stovetop. In a large pot or Dutch oven, heat the oil over medium heat. Add the sliced leeks and minced garlic, cooking for 5-7 minutes until softened and aromatic, stirring occasionally. Next, add the quartered potatoes, vegetable broth, water, thyme, and the bay leaf. Increase the heat to high and bring the mixture to a gentle simmer. Once simmering, reduce the heat to low, cover the pot, and let it cook for 20-25 minutes, or until the potatoes are fork-tender. Turn off the heat and proceed with blending as described below.
- **Blending Hot Liquids Safely:** For the creamiest results, an immersion blender is ideal as it allows you to blend directly in the pot. If using a standard blender, work in small batches. Fill the blender only halfway, ensuring the lid is securely fastened. Crucially, remove the center cap of the blender lid (the feeder cap) and cover the opening with a kitchen towel to allow steam to escape. This prevents dangerous pressure buildup. Blend until smooth, then transfer to a separate bowl before blending the next batch.
- **Potato Varieties:** While Russet potatoes are recommended for their starchy texture, which naturally thickens the soup, other potato varieties can also be used. Yukon Gold (yellow) potatoes will yield a slightly waxier, yet still creamy, soup with a rich, buttery flavor. Red potatoes can also work, though they might require a bit more blending for a perfectly smooth consistency. Experiment to find your favorite!
- **To Peel or Not to Peel:** Peeling your potatoes will result in an exceptionally smooth and silky soup texture, which is often preferred for a classic potato leek soup. However, leaving the skins on adds extra fiber and nutrients, and gives the soup a slightly more rustic character. If you choose to keep the skins, ensure you scrub the potatoes thoroughly before cooking.
- **Proper Leek Preparation:** Leeks can harbor dirt between their layers, so proper cleaning is essential. To prep leeks, first trim off the tough, dark green tops and the root end. Then, make a lengthwise slit down the leek from just above the white part almost to the root. Fan out the layers under cold running water, rinsing away any trapped dirt or grit. Once clean, slice the leek, primarily using the white and light green parts. Discard the very tough, dark green sections.
- **Leek Substitutes:** If leeks are unavailable or you simply prefer another option, a large white or yellow onion can be used in their place. While the flavor profile will be slightly different (more assertive onion flavor), it will still create a delicious and aromatic base for your soup.
- **Understanding Instant Pot Cook Time:** The stated 6-minute cook time for the Instant Pot is for active pressure cooking. Keep in mind that your Instant Pot will also take approximately 10-15 minutes to come up to pressure before the 6-minute timer begins. Additionally, allowing for a natural pressure release of 5-10 minutes adds to the total hands-off time.
- **Serving Suggestions & Garnish:** This potato leek soup is delightful on its own, but a garnish can elevate the experience. Freshly chopped chives add a pop of color and a mild, fresh onion flavor. Other excellent additions include crispy croutons, a swirl of vegan sour cream or crème fraîche, a sprinkle of smoked paprika, or a generous slice of crusty bread for dipping.
Frequently Asked Questions About Potato Leek Soup
Here are some common questions about making and storing this delicious Instant Pot Vegan Potato Leek Soup:
Absolutely! This soup freezes beautifully. Once it has cooled completely, transfer it to freezer-safe containers or bags, leaving about an inch of headspace to account for expansion. It can be stored in the freezer for up to 3 months. When you’re ready to enjoy it again, simply transfer the frozen soup to a pot and reheat gently over low heat, stirring occasionally until thawed and brought to a simmer. Adjust seasoning if needed before serving.
For optimal flavor and freshness, this vegan potato leek soup will keep well in an airtight container in the refrigerator for up to 4 days. It makes for an excellent make-ahead meal or quick weeknight dinner. To reheat, you can either warm it on the stovetop over medium-low heat or in the microwave until heated through. Stir well before serving.
This recipe is naturally vegan and dairy-free because it uses plant-based ingredients exclusively. Instead of heavy cream or butter (common in traditional potato leek soups), we rely on the natural starchiness of russet potatoes to create a wonderfully creamy texture, along with olive oil for sautéing. Vegetable broth is used as the liquid base, ensuring it remains entirely plant-based. The result is a rich, satisfying soup that doesn’t compromise on flavor or texture, even without animal products.
Yes, this soup is quite versatile! While the classic recipe is focused on potatoes and leeks, you can certainly add other complementary vegetables. A handful of chopped carrots or celery added with the leeks and garlic can add extra flavor and nutrients. A cup of frozen peas or spinach can be stirred in after the soup is blended, just to heat through, for a pop of color and freshness. Be mindful that adding too many other vegetables might alter the core potato-leek flavor, so add sparingly at first.

Instructions
- Press the “Sauté” button on a 6-quart or 8-quart Instant Pot. Drizzle in the oil and let it heat up for a few minutes. (See notes for stovetop directions.)

Notes
- **STOVETOP DIRECTIONS:** In a large pot or Dutch oven, heat the oil over medium heat. Add the leeks and garlic and cook for a few minutes, stirring occasionally.

Reduce heat to low, cover the pot, and let it simmer for 20-25 minutes, or until the potatoes are fork-tender. Turn off the heat and use a hand immersion blender to blend to desired consistency.

- You can use other types of potatoes for this recipe, including red potatoes or gold (Yukon Gold) potatoes, for slightly varied texture and flavor.
- Peeling the potatoes is optional; it will result in a silkier soup, but leaving the skins on adds fiber and a more rustic texture.
