What I love about this Soup
I love the use of sour cream in this recipe, which gives it a delightful tanginess and richness. You can also use yogurt with a similar effect. While the soup simmers, whip up the flavorful Leek oil made the green leek tops. Drizzle this over the soup for a boost of leek flavor!

To be honest, in the past I have tended to shy away from Potato Leek Soup because of the many occasions when ordered, it arrived bland and lifeless.
This version, I assure you, is not. It’s rich and flavorful, all the while staying light and healthy.

Ingredients in Potato Leek Soup
- Leeks
- Olive oil (or butter or ghee)
- Garlic
- Fresh thyme (or sub dry thyme)
- Potatoes- yukon gold potatoes, russets, or any thin-skinned potatoes- red, fingerling.
- veggie broth or chicken stock
- salt and pepper
- Sour cream, or sub-heavy cream. See notes for vegan version.
- Fresh chives (or scallions) for garnish
How to make Potato Leek Soup
Step One: Slice the leeks into ¼-inch slices using the white, yellow and pale green parts. Rinse under running water to remove any dirt. You’ll need about 4-5 cups.

TIP: If feeling even just a little ambitious, save the dark green tops and make the flavorful Leek Oil! You can do this while the soup is simmering. Use this Leek oil to drizzle over the soup and many other things.

Step 2: Saute the leeks and garlic over medium-low heat until leeks are tender, about 8-10 minutes.

Step 3: Add the thyme, broth and sliced potatoes, cover, and simmer gently until tender ( about 15 minutes)

Step 4: Blend the soup until just creamy. Over-blending may create a “gummy” texture- so just blend until mostly smooth.

Step 5: Whisk in sour cream or heavy cream. ( See notes for vegan version).

Season. Taste and adjust salt and pepper to taste.

Serve in bowls with chives, or a swirl of leek oil and crusty bread. Or make this Leek Bread!

Serve this cozy soup with warm, crusty bread and a side of our White Bean Salad!
Storage
- Refrigerate any leftovers for up to 4 days.
- Freeze Potato Leek Soup without the sour cream for up to 6 months.
Hope you enjoy this simple Potato Leek Soup as much as we do!

Description
This delicious healthy recipe for Potato Leek Soup is deceiving flavorful! A nourishing, soul-satisfying meal made with the humblest of ingredients. Serve with optional Leek oil and Crusty Bread.
Ingredients
- 3–4 large leeks, (4–5 cups sliced)
- 3 tablespoons olive oil (or sub butter or ghee)
- 4 cloves garlic, rough chopped
- 1 tablespoon fresh thyme (or 1 tsp dry thyme)
- 1 1/2 pounds yukon gold potatoes, thinly sliced. Or sub any thin-skinned potatoes- red, fingerling, or use russets, peeled.
- 4 cups veggie broth or chicken stock
- 1 teaspoons salt, more to taste
- 1/2 teaspoon fresh cracked pepper
- 1/2 cup sour cream (or heavy cream) see notes for vegan.
- 2 tablespoons fresh chives (or scallions) for garnish
Optional – Leek oil for drizzling! (Make this with the green tops of leeks while the soup simmers.)
Instructions
- Slice leeks into ¼-inch thick slices. Rinse under running water to remove dirt and sediment. Drain. ( The water will help soften the leeks as well.)
- Heat oil in a heavy-bottom pot or dutch oven, over medium-low heat. Add rinsed leeks and garlic and thyme, sauté until tender, golden and fragrant, 8-10 minutes.
- Add potatoes, stock, salt, and pepper. Bring to a boil, cover, turn heat to low and simmer, covered, for 15-20 minutes, until potatoes are fork-tender.
- Make the optional leek oil.
- Blend the soup. When the potatoes are very tender, use an immersion blender and blend the soup until relatively smooth. TIP: Over blending may cause the soup to have a gummy texture. Alternatively, blend in batches in a regular blender (remember, you don’t want to fill up a blender with hot liquid, or you will have a soup explosion- so blend in small batches, less than half full, holding the lid down firmly covered with a kitchen towel. )
- Return the blended soup to the pot, and whisk in the sour cream. Taste and adjust salt and pepper. Gently warm over low heat.
- To serve, divide among bowls, drizzle with the leek oil, sprinkle with fresh chives or scallions.
Notes
To make this vegan, you can altogether leave out the dairy- it is quite creamy on its own. Or use vegan sour cream or vegan cream. Alternatively, you could add a 1/4-1/2 cup raw cashews to the simmering potatoes and leeks, and let them get soft. Blend the soup. Place back in the pot. Add a couple of drops of vinegar or lemon juice (1/4 teaspoon) and stir in a teaspoon or two of nutritional yeast to taste if you like. Adjust salt and pepper.
