The magic of this Potato and Leek Soup with Truffle Oil Recipe lies in its simplicity. Each ingredient plays a crucial role, from the tender Yukon Gold potatoes that create the creamy texture to the sweet leeks adding delicate depth of flavor. The butter or olive oil helps bring everything together with a silky finish, while the broth and cream provide warmth and richness.

Butter or olive oil: Use 2 tablespoons to gently sauté and soften the leeks without browning them.
Leeks: 3 large, using only the white and light green parts, thinly sliced for the sweetest, most tender bite.
Garlic: 2 cloves, minced to add a subtle aromatic punch that complements the leeks.
Yukon Gold potatoes: 1½ pounds peeled and diced for the perfect creamy body and a naturally buttery flavor.
Vegetable or chicken broth: 4 cups to simmer the vegetables and infuse the soup with savory depth; choose vegetable broth for a vegetarian option.
Heavy cream or half-and-half: ½ cup for that irresistibly silky finish, or sub in milk for a lighter version.
Salt and black pepper: To taste, essential for balancing and enhancing the flavors.
Truffle oil: Just a drizzle to bring an elegant, earthy fragrance that transforms the soup.
Optional garnish: Chives, cracked black pepper, or crunchy croutons to add color, texture, and extra flavor.

How to Make Potato and Leek Soup with Truffle Oil Recipe

Step 1: Soften the Leeks

Start by heating your butter or olive oil in a large pot over medium heat. Add the sliced leeks and sauté gently for 8 to 10 minutes until they are very soft but not browned. This slow cooking softens the leeks, bringing out their natural sweetness and creating the foundation of flavor your soup will build on.

Step 2: Add Garlic

Stir in the minced garlic and cook for about 30 seconds until fragrant. Adding garlic at this stage ensures it releases its delicious aroma without overpowering the soup’s delicate nature.

Step 3: Simmer Potatoes and Broth

Next, add your diced Yukon Gold potatoes and pour in the broth. Bring everything to a gentle boil, then reduce the heat and let it simmer for 20 to 25 minutes. The potatoes should be tender and ready to blend, soaking up all that lovely leek and garlic flavor.

Step 4: Blend Until Smooth

Using an immersion blender or transferring to a countertop blender, blend the soup until perfectly smooth. This step transforms the chunky ingredients into a silky, velvety base that will delight your taste buds with every spoonful.

Step 5: Stir in Cream and Season

Return the soup to the pot if you used a blender and stir in the cream or half-and-half. Taste carefully and season with salt and black pepper to your liking. The cream softens the flavors even more, making the soup incredibly rich without being heavy.

Step 6: Finish with Truffle Oil

Finally, ladle the soup into bowls and drizzle lightly with truffle oil. This final touch adds an elegant, earthy fragrance and flavor that elevates the humble ingredients to a luxurious experience.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers, store them in an airtight container in the refrigerator. The soup will keep well for 3 to 4 days, during which the flavors continue to meld beautifully.

Freezing

This soup freezes exceptionally well! Pour cooled soup into freezer-safe containers or bags, leaving space for expansion, and freeze for up to 3 months. Avoid freezing the soup after cream is added if possible, to maintain the best texture.

Reheating

Reheat gently over low to medium heat on the stove, stirring frequently. Add a splash of broth or cream if the soup thickens too much upon standing or after freezing. Avoid boiling to keep that rich and creamy consistency you love.

FAQs

Can I use other types of potatoes?

Absolutely! While Yukon Gold potatoes provide a naturally buttery, creamy texture perfect for this soup, Russet or red potatoes will also work. Just keep in mind that their starch content might slightly change the soup’s consistency.

Is truffle oil necessary?

Truffle oil is the star that elevates this simple soup into something special, but if you don’t have it, the soup will still taste delicious on its own or with a different finishing oil like olive oil. Just use truffle oil sparingly, as it is very potent.

Can this recipe be made vegan?

Yes! Use olive oil instead of butter, opt for vegetable broth, and substitute heavy cream with a plant-based cream alternative, such as cashew cream or coconut milk, to keep it creamy and vegan-friendly.

How do I clean leeks properly?

Leeks hold dirt between their layers, so it’s important to rinse them thoroughly. Slice the leeks, then soak them in a bowl of cold water, swishing them around to release any grit before draining and drying.

Can I make this soup ahead for a party?

Definitely! This Potato and Leek Soup with Truffle Oil Recipe tastes even better the next day. Just reheat gently, add your truffle oil drizzle at the last moment, and garnish freshly for a warm, welcoming starter that feels made in advance but serves like a dream.
