What You Need: Ingredients List?
This potato leek soup for vegans only needs 8 ingredients you can easily get your hands on.
Let’s start by looking at some key flavor notes to include!
- Leeks: This is critical; it is potato leek soup! Leeks are fantastic in soup as they have a unique sweet yet oniony flavor similar to green onions. However, add some celery if you want the taste to be complete!
- Potatoes: For the richest and creamiest soup, use Yukon gold potatoes. These potatoes blend perfectly, and since they are naturally high in starch, they are the perfect choice for a nice and thick soup!
- Coconut Milk: Full-fat coconut milk is not everyone’s choice, but it is excellent to use if you want that richness that can make a big difference to a dish.
- Broth: A vegan chicken-flavored broth is probably the most flavorful option. However, any vegetable broth will do fine!
- Potatoes: Opt for starchy potatoes like Russets or Yukon Golds. They’ll break down better during cooking and yield a creamier soup.
- Leeks: Clean leeks thoroughly, as they can trap soil between their layers. Slice off the dark green tops, retaining the white and light green parts with a milder and sweeter flavor.
- Stock: Homemade vegetable or chicken stock brings more depth to the soup, but quality store-bought stock can work well in a pinch.
- Cream: Add a dash of cream at the end for a richer soup. Omit the cream or use coconut milk for a lighter, dairy-free version.
- Seasoning: Remember to skimp on seasoning. Freshly ground black pepper and sea salt can dramatically enhance the soup’s flavor.
- Garnish: Chives, parsley, or even a sprinkle of cheese make for visually appealing and tasty garnishes.
Can You Vary The Soup With Other Ingredients?
Here are some variations to suit different dietary preferences:
- Keto: For a keto-friendly version, use heavy cream instead of milk and avoid starchy thickeners. You can even add some bacon for a smoky twist.
- Paleo/Whole30: Use ghee or coconut oil instead of butter and dairy-free milk like almond or coconut. Make sure your stock is also compliant with these diets.
- Gluten-Free: This soup is naturally gluten-free if you use gluten-free stock. Always check the labels of pre-packaged stocks to ensure there are no hidden sources of gluten.
- Vegetarian: Use vegetable stock instead of chicken stock. For an extra boost of protein, you could add some white beans.
- Vegan: Replace butter with olive oil or vegan margarine, use vegetable stock, and substitute dairy cream with a plant-based alternative like coconut cream or almond milk.
- Prepare your leeks first, ensuring they are entirely cleaned (this is very important, as dirt, bacteria, and even small bugs can hide between the leaves). Then, chop and prep the rest of your ingredients.
- Before you start cooking, chop the celery, mince the garlic, chop the potatoes, and prepare the broth.
- Sauté your aromatics first, starting with your butter/olive oil/ broth in the pan with the leeks. Then, once cooked, add your aromatics, such as the garlic, celery, thyme, and bay leaves.
- Once fragrant and tender, add your potatoes and the liquids and boil before simmering for ¼ an hour until the potatoes are tender.
- Then, blend the soup until smooth with an immersion, vented normal blender, or a soup-friendly high-quality blender.
- Once completed, serve warm with toppings such as croutons, celery leaves, etc. Store as you wish.
Variations, Add-Ons And Toppings
Not all of these ingredients work for everyone or at all times of the year, so being aware of the variations of this soup you can make and what substitutions are viable is always a good idea!
- Potato variations: Most prefer using Yukon gold potatoes for this recipe as they have a super smooth texture when you blend them. However, if you do not like these, Russet is just fine!
Russet potatoes will be drier. However, once blended, the soup should still be just as smooth!
- Leek Substitutions: There is no great substitute for leeks; however, if there are no leeks in season, when you want to make this soup. You could use frozen leeks.
If doing this, add the leeks to the pot of melted butter straight from the freezer and sauté them for 3–5 minutes, ensuring all of their liquid has been evaporated.
- Substituting Coconut Milk: You can use equal parts of full-fat oat milk or even an unsweetened vegan creamer to substitute coconut milk, as we know it is not to everyone’s taste.
If you are skilled in the kitchen, you could make your cashew cream by blending up ¾ cup of cashews (soaked) with a single cup of water.
- Oil-Free Variations: If you want to avoid oils, you can sauté the aromatics of the recipe in a splash of water or a broth instead!
Scaling The Recipe
Scaling the Potato Leek Soup recipe up or down is a matter of simple math. Most soup recipes, including this one, are quite forgiving, making them ideal for adjusting to your needs. Here are some general tips:
- If you’re hosting a larger gathering, you can easily double or triple the recipe. Just multiply each ingredient by the same factor. For example, if the recipe calls for 2 leeks and 4 potatoes for 4 servings, use 4 and 8 potatoes for 8 servings. Also, ensure your cookware is large enough to handle the increased volume.
- If you’re cooking for fewer people, halve or reduce the quantities of each ingredient accordingly. Remember that the cooking time might decrease slightly with less volume, so check for doneness earlier.
What Is Used For Garnishing?
The Potato Leek Soup recipe often uses freshly chopped parsley for garnishing. However, you can get creative and use a variety of other garnishes to add color, texture, and additional flavor to the soup. Some popular choices include:
- Fresh Herbs: Besides parsley, chives, thyme, or dill can provide a new, vibrant touch.
- Cream or Olive Oil: A drizzle can add a rich, visually appealing finish.
- Cheese: A sprinkle of grated parmesan, cheddar, or crumbled blue cheese can add a deliciously savory note.
- Croutons add a delightful crunch and can be especially enjoyable if homemade.
- Bacon Bits: If you’re not adhering to a vegetarian or vegan diet, crisp bacon bits can add a smoky flavor and crunchy texture.
- Green Onions or Leeks: A few slices can enhance the leek flavor and add a pop of color.
Can I Make Soup In A Slow Cooker Or Instant Pot?
A slow cooker and Instant Pot can be used to prepare Potato Leek Soup, offering you the convenience of hands-off cooking. Here’s how:
- As usual, begin by sautéing the leeks in butter and white wine, then transfer them to the slow cooker. Add the potatoes and chicken stock, cover, and cook on low for 6-8 hours or on high for 3-4 hours.
- Once the potatoes are tender, use an immersion blender to puree the soup in the slow cooker or carefully transfer it to a countertop blender in batches. If needed, stir in seasonings and additional stock, then serve garnished with parsley.
- Using the sauté function, cook the leeks in butter and white wine directly in the Instant Pot. Add the potatoes and chicken stock, then secure the lid and set to pressure cook on high for 15 minutes.
- Once the cooking time is up, allow a natural pressure release for about 10 minutes before performing a quick release. Puree and season the soup as described above.
Can I Use Store-Bought Broth, Or Should I Make My Own?
Both store-bought and homemade broth can be used to make Potato Leek Soup, depending on your preference, time constraints, and dietary needs.
- It is a convenient option when you’re short on time. There are many high-quality, flavorful broths available in stores. Look for low-sodium versions to control your soup’s salt level.
- If you have specific dietary restrictions, read labels to ensure the broth meets your needs.
- Making your broth allows you to customize the flavor profile and control the ingredients. It’s a great way to utilize leftover chicken bones or vegetable scraps, making it a cost-effective and waste-reducing option.
- Homemade broth typically has a richer flavor than store-bought, which can enhance the overall taste of your soup.
Can I Use Different Types Of Meat/Fish/Pasta/Vegetables For The Soup?
Potato Leek Soup is a versatile recipe that can easily accommodate a variety of additional ingredients, allowing you to experiment and create a version that suits your taste. Here are some ideas:
- Meat: Adding cooked, shredded chicken can make the soup heartier. Smoky bacon is another flavorful addition. Cook it until crisp, crumble it, and add it to the soup before serving.
- Fish: Add cooked, flaked white fish or shrimp for a seafood twist. Add these towards the end of cooking to avoid overcooking the seafood.
- Pasta: Small pasta shapes like orzo or ditalini could be added to the soup to create a more filling meal. Cook the pasta separately and add it before serving to prevent it from becoming too soft.
- Vegetables: Many vegetables would work well in this soup. Add diced carrots, celery, spinach, or kale for extra nutrition. These can be added during the simmering stage so they cook until tender.
Success Tips – Tips And Tricks For Making The Soup
If you are new to making soups and cooking with leeks, we have some top tips to help you make the most out of this soup!
- Choose Fresh Leeks: Select fresh leeks with firm, white and light green parts. Rinse them thoroughly to remove any dirt or grit between the layers.
- Use Yukon Gold Potatoes: Opt for Yukon Gold potatoes for their creamy texture and rich flavor. They hold up well in soups and contribute to a velvety consistency.
- Sauté Aromatics: Begin by sautéing leeks and onions in butter or olive oil until softened. This foundational step builds a flavorful base for the soup.
- Garlic Enhancement: Add minced garlic for an extra layer of savory flavor. Adjust the amount to suit your taste preferences.
- Simmer with Broth: Choose a good-quality vegetable or chicken broth to enhance the soup’s depth of flavor. Homemade broth is ideal, but store-bought works well too.
- Seasoning: Season the soup with salt, pepper, and a bay leaf. Consider adding thyme or rosemary for a herbal touch that complements the leeks and potatoes.
- Clean and Slice Leeks Properly: Trim the roots and dark green parts of the leeks. Slice them lengthwise, then chop into thin half-moons. Rinse thoroughly to remove any dirt between the layers.
- Uniform Potato Cubes: Ensure uniformity in potato size for even cooking. Aim for bite-sized cubes to expedite the cooking process.
- Mince Garlic in Advance: Pre-mince garlic to save time during the cooking process. This ensures the garlic incorporates evenly into the soup.
- Chop Ingredients Ahead: Chop onions, leeks, and potatoes ahead of time to streamline the cooking process. Store them separately to maintain freshness.
- Prepare Homemade Broth: If possible, use homemade vegetable or chicken broth for superior flavor. Prepare it in advance or use high-quality store-bought broth.
- Measure Ingredients: Pre-measure herbs, spices, and other ingredients to have them ready for quick incorporation into the soup.
Cooking Time Tips
- Sauté Leeks and Onions First: Begin by sautéing leeks and onions until soft and translucent. This foundational step enhances the overall flavor of the soup.
- Add Garlic Carefully: Add minced garlic towards the end of the sautéing process to prevent it from burning. Stir it in for about 30 seconds until fragrant.
- Simmer for Flavor Development: Allow the soup to simmer on low heat to allow the flavors to meld. This step is crucial for a rich and well-developed taste.
- Potato Cooking Time: Monitor the potato cooking time closely to achieve a tender yet slightly firm texture. Overcooked potatoes can result in a mushy consistency.
- Gradual Cream Incorporation: If using cream or milk, add it gradually, stirring continuously. This prevents curdling and ensures a smooth, creamy texture.
- Puree with Caution: If using a blender, allow the soup to cool slightly before blending to avoid splattering. Puree in batches if necessary for a consistent texture.

When you’re ready to serve the soup, reheat it gently on the stovetop over medium heat, stirring occasionally.
If the soup has thickened in the fridge, add water or stock to thin it out to your desired consistency. Always check the seasoning after reheating, as you might need to adjust it.

Leftover Potato Leek Soup doesn’t have to be reheated and eaten as is – it can be repurposed into new dishes, adding versatility to your meal planning:
- Pasta Sauce: Blend the soup to a smooth consistency and use it as a creamy sauce for pasta. Add some grated cheese and black pepper for extra flavor.
- Potato Gratin: Use the soup as a flavorful base for a potato gratin. Layer sliced potatoes in a baking dish, pour over the soup, top with cheese, and bake until golden.

- Chowder Base: Add corn, bacon, or seafood to make the soup hearty chowder.
