My favorite thing about this comforting soup…

It brings back wonderful childhood memories eating at my grandfather’s favorite “fancy occasion” restaurant & celebrity haunt, Scandia, in Hollywood. It was such a special treat to eat there. Everything was delicious, but most especially their creamy, dreamy, Vichyssoise.

If you’re not familiar with Vichyssoise, the main ingredients are potatoes and leeks, like this healthy potato soup recipe. BUT it’s also made with heavy cream AND it’s served cold. And, cold soup is one of the few things my hubby, Mr. Spicy, doesn’t like.

So, this warm vegan leek and potato soup is a delicious compromise and Mr. Spicy approved!

What ingredients do you need to make this easy recipe for potato leek soup?

You only need 5 ingredients for this simple recipe. Plus salt to taste and optional toppings-like yummy Spring pea shoots!

Image featuring 6 ingredients (vegetable broth, potatoes, leeks, onion, vegan butter, pea shoots) to make vegan leek and potato soup.

Potatoes

My recipe calls for Yukon Gold potatoes because they add a naturally creamy consistency to the soup. But, feel free to experiment with russet potatoes, purple potatoes (that would be so pretty!), sweet potato, red potatoes, or whatever potatoes you have on hand.

Chopped Leeks

While you can typically find leeks in the grocery store year round, especially late winter to early summer, early Spring is a perfect time to enjoy them.

Tip! Leeks are a dirty veggie. To clean leeks, be sure to clean & rinse ’em well to remove all the loose dirt.

Onion

I suggest choosing a sweet version, like Maui or Vidalia, for a subtle layer of additional flavor.

Vegetable Stock

I love making this potato soup recipe with Organic Imagine Vegetarian No Chicken Veggie Broth instead of chicken broth. But, feel free to use any vegetable broth you like.

Vegan Butter

I like Earth Balance Organic Whipped Buttery Spread or Melt Organic Spread to provide a buttery flavor. Extra virgin olive oil or avocado oil, both rich in heart healthy monounsaturated fats would work well too.

Optional Ingredients

Non-Dairy Milk: I don’t use any milk in this vegan potato soup, but feel free to add almond milk, coconut milk, coconut cream, cashew milk, or cashew cream for an extra creamy vegan potato leek soup recipe. If you want a little protein boost, swirl in organic soy milk.

Seasonings: Salt, nutritional yeast, black pepper, Dijon mustard, a splash of lemon juice…

Toppings: Spring pea shoots! Green onions, fresh parsley, dill, thyme sprigs, fresh chives, a drizzle of olive oil…

You can make this Vegan Leek and Potato Soup in one large soup pot!

You’ll want a large pot or Dutch Oven (I LOVE my Le Creuset) to make this creamy vegan potato leek soup. Or, try making it in an Instant Pot and let me know how it turns out!

Beyond that, you’ll need your typical measuring cups and utensils, plus a hand-held immersion blender. Don’t have one? Use a regular blender instead.

Note: You can meal prep this creamy vegan leek soup ahead of time. Make a big batch to freeze, or store in in an airtight container in the refrigerator for up to 3 days.

Vegan Leek and Potato Soup Nutrition Information

This creamy potato leek soup recipe is light on calories, full of flavor, & packs a healthy punch!

Low in fat and calories. Rich in taste!

At less than 200 calories and 5 grams or fat per serving, this vegan leek and potato soup is much lower in fat & calories than traditional vichyssoise or classic potato leek soup made with cream. And, while I have nothing against enjoying a little heavy creamy once in awhile, I promise you won’t miss it in this luscious vegan leek and potato soup!

Leeks are laced with nutrients.

Sulfur and flavanoid rich leeks belong to the allium family, which also includes garlic and onions. Potential health benefits include cancer preventionand protection against cardiovascular disease.

In addition, leeks are an excellent source of vitamins A and K (good for bone health), and a very good source of vitamins C and folate~ an important B vitamin that helps support methylation.

Did I mention leeks are also a prebiotic rich food, important for gut health?

Leeks

Potatoes are nutrition rockstars.

Not only do they provide the creamy texture in this vegan soup recipe, potatoes are packed with vitamin C, potassium, and other key nutrients. There’s no reason to give them up for health reasons. Just sayin!

And, if you choose to enjoy this vegan leek and potato soup cold, a la Vichyssoise, you’re getting some gut healthy resistant starch in your diet too. Pretty cool (literally AND figuratively) right?!
