Leek Potato Soup: A Classic Recipe

This classic soup recipe originates from Wales, and is traditionally made with potatoes, leeks, chicken broth and heavy cream. There is another variation called Vichyssoise which is a cold leek potato soup invented in 1917 America and named after the French town, Vichy.

This version is made creamy without the use of dairy, and is made flavorful with vegetable stock and nutritional yeast.

Vegan Leek Potato Soup

This is a simple recipe made with ingredients you likely have in your pantry. Vegan potato leek soup also comes together with little fuss, which I always love. This recipe is a high protein take on this traditional and well-loved soup with the addition of white beans.

My preference is to also  in a handful of fresh parsley, spinach, or chopped kale from the garden to help me feel as though I'm more health conscious than I may or may not be at the moment!

Leeks: Abundant and Flavorful

Leeks are a hardy winter vegetable grown year round.  These tasty alliums are mild in flavour compared to onions, and are widely available at local markets or grocers, especially throughout the fall and winter months. In my own garden, I grow leeks starting in early February when I pull the very last one from the year prior.  

Of course, everyone loves leeks with potatoes (right?).  Their flavours together remind me of many homemade lunches with my dad; a hot bowl of leek and potato soup with a slice of German rye bread is such a nourishing meal on a cold day.

White Beans for Creaminess

The addition of white beans (Cannellini beans) makes this soup extra creamy and adds a boost of plant-based protein. White bean also contain lots of fiber and load of other healthful nutrients. They blend into this soup seamlessly.

What you will need

The ingredient list if fairly simple, however, you may or may not have nutritional yeast on hand; this is the most exotic ingredient, however it is readily available at most grocery stores.

• olive oil
• small white onion
• leeks
• garlic
• yukon gold or nugget potatoes
• low sodium vegetable broth (gluten-free, if necessary)
• cooked cannellini beans
• nutritional yeast
• Sea salt & pepper to taste
• Fresh chopped parsley or spinach for serving

How to make this recipe

This recipe comes together in one pot. To get a creamy texture, I use an immersion blender. All in all it takes roughly 50 minutes to make this recipe. Details on the instructions are below, however, here is a quick synopsis.

First, prep the vegetables, then add the onion, leeks and garlic to a large pot with some heated oil. The leeks, onion and garlic need to cook for about 5 minutes. The potatoes go in next, along with the white beans and vegetable stock. Then the soup simmers for 25-30 minutes or until the potatoes are soft.

Next, the nutritional yeast goes in, along with salt and pepper. Then,the soup is lightly blended with an immersion blender to the desired consistency.  It is ready to serve with fresh bread and topped with whatever green veg you may like.

Tips to make this recipe perfect

• Leeks are grown in somewhat gritty well draining soil. As such, it's a good idea to wash the leeks in a sieve after chopping them to make sure all the grit is removed.
• When prepping the leeks, you want to use only the white and light green parts; the darker green leaves are woody and not appetizing. Compost the leaves!
• Make sure you scrub the potatoes well to remove any dirt or grit.
• Nutritional yeast is optional, but it really makes this recipe super flavorful.
• Puree the soup to your desired consistency; silky smooth, or slightly chunky.
• Serve this recipe with any of the following garnishes: fresh chopped kale, spinach, parsley, dill, gluten-free croutons, or fresh cracked pepper.

Storage

This recipe will last in the fridge covered for 2-3 days. Moreover, I have also frozen it in a freezer-safe container for up to three months; just make sure it is cool before storing it. To serve it from frozen, defrost it in the fridge and reheat on the stove until heated through.
