Ingredients

3 tablespoons unsalted butter
3 large leeks, thinly sliced (white parts and a bit of the green parts)

1/2 teaspoon salt
2 large Yukon Gold potatoes, peeled and cut into 1-2 inch chunks
3 cups chicken stock or vegetable stock

2/3 cup heavy cream
Kosher salt to taste
Freshly ground black pepper to taste

Chopped fresh chives for garnish

Directions

Preparing the Leeks

Melt the Butter:

In a Dutch oven or large pot, melt the butter over low heat.

Cook the Leeks:

Add the leeks and salt.
Cook until the leeks are very tender, pasty, and broken down, stirring frequently. This will take 25-35 minutes.

Adding the Potatoes and Stock

Combine with Potatoes and Stock:

Add the potatoes and chicken stock to the pot.
Bring the mixture to a gentle boil.
Cook until the potatoes are very tender, about 20 minutes.

Blending the Soup

Puree the Soup:

Remove the pot from the heat.
Using an immersion blender or a stand blender (remember to remove the center cap to avoid steam build-up), puree the mixture until very smooth and creamy.

Finishing Touches

Stir in the Cream:

Stir in the heavy cream.
Season with kosher salt and freshly ground black pepper to taste.

Garnish and Serve:

Ladle the soup into bowls.
Garnish with chopped fresh chives.

Tips for the Perfect Vichyssoise

Cooking the Leeks

Ensure the leeks are very soft before blending to achieve a smooth puree. This step is crucial for the soup’s velvety texture.

Swirling the Cream

For a decorative touch, swirl a little extra cream into the soup. Use a small cup to drizzle the cream in a circular motion, then use a shish kabob stick to create a swirl or figure-eight pattern.

Choosing the Stock

Use chicken stock, chicken broth, or vegetable broth. Low-sodium options are preferred to better control the soup’s saltiness.

Blending Safely

If using a stand blender, remove the center cap from the lid to allow steam to escape and prevent pressure build-up, which can cause hot soup to spray out.

Variations

Adding Herbs

Enhance the flavor by adding herbs such as thyme or bay leaves during the cooking process. Remove them before blending.

Making it Vegan

Substitute butter with olive oil and heavy cream with coconut milk or cashew cream for a vegan version of this classic soup.

Adding Protein

For a heartier meal, add cooked, shredded chicken or crispy bacon bits as a garnish.

FAQs

Can I make Vichyssoise ahead of time?

Yes, Vichyssoise can be made a day or two in advance. Store it in the refrigerator and serve it chilled or reheat it gently on the stovetop.

How long does Vichyssoise last in the fridge?

It can be stored in an airtight container in the refrigerator for up to 5 days. Make sure to stir well before serving.

Can I freeze Vichyssoise?

Yes, you can freeze Vichyssoise. Allow it to cool completely, then transfer it to a freezer-safe container. It can be frozen for up to 3 months. Thaw in the refrigerator overnight before reheating.

What can I serve with Vichyssoise?

Vichyssoise pairs well with crusty bread, a light salad, or even a grilled cheese sandwich. A glass of white wine, such as Chardonnay, complements the flavors beautifully.

Can I use other types of potatoes?

Yukon Gold potatoes are preferred for their creamy texture, but you can use russet or red potatoes if needed. Keep in mind that the texture may vary slightly.

Is there a dairy-free option?

Yes, you can substitute the heavy cream with a plant-based alternative like coconut milk, almond milk, or cashew cream for a dairy-free version.

How can I adjust the thickness of the soup?

If the soup is too thick, add a bit more stock or cream until the desired consistency is reached. If it’s too thin, simmer it for a bit longer to reduce and thicken.

What if I don’t have an immersion blender?

A stand blender works well, but blend the soup in batches to avoid overfilling. Always remove the center cap of the blender lid to allow steam to escape and prevent accidents.
