Ingredients

Main Ingredients:

2 tablespoons unsalted butter (or olive oil for dairy-free)
3 large leeks (white and light green parts only), cleaned and sliced
2 cloves garlic, minced
4 medium Yukon Gold or russet potatoes, peeled and diced
4 cups (1 liter) low-sodium vegetable or chicken broth
1 cup (240 ml) whole milk or heavy cream (or coconut milk for vegan)
2 teaspoons fresh thyme leaves (or 1 teaspoon dried thyme)
1 bay leaf
Salt and freshly ground black pepper, to taste
1 tablespoon olive oil (optional, for drizzling)

For Garnish (Optional):

Chopped chives or parsley
Crispy croutons or bacon bits (optional)
Extra cream swirl or grated Parmesan cheese

Equipment:

Large pot or Dutch oven
Immersion blender (or countertop blender)
Ladle and whisk

Instructions

1. Prepare the Leeks

Trim the root ends and dark green tops of the leeks, keeping only the white and pale green parts. Slice them lengthwise, then rinse under cold water to remove any dirt hidden between the layers. Slice the cleaned leeks thinly into half-moons.

2. Sauté the Aromatics

In a large pot, melt butter over medium heat. Add the sliced leeks and cook for 6–8 minutes, stirring often, until soft and fragrant but not browned. Add the minced garlic and cook for another 30 seconds until aromatic.

3. Add the Potatoes and Broth

Stir in the diced potatoes, thyme, bay leaf, and a generous pinch of salt and pepper. Pour in the broth and bring the mixture to a boil. Once boiling, reduce the heat to low and simmer uncovered for 20–25 minutes, or until the potatoes are tender and easily pierced with a fork.

4. Blend Until Smooth

Remove the bay leaf and carefully blend the soup until creamy. Use an immersion blender directly in the pot for convenience, or transfer the soup in batches to a countertop blender. Blend until perfectly smooth and velvety.

5. Add Cream and Seasoning

Return the blended soup to low heat. Stir in the milk or cream and let it warm gently for 2–3 minutes (do not boil). Taste and adjust the seasoning with additional salt and pepper. For a richer flavor, drizzle in a little olive oil or add a knob of butter just before serving.

6. Serve and Garnish

Ladle the soup into bowls and garnish with your choice of toppings—chopped chives, a swirl of cream, or crispy croutons. A sprinkle of thyme leaves or a drizzle of olive oil adds a restaurant-style finish.

Tips for Perfect Potato Leek Soup

Clean the leeks well: Dirt often hides in the layers—rinsing thoroughly is key.
Choose the right potatoes: Yukon Golds make the soup creamy; russets make it fluffier.
Don’t rush blending: A smooth texture depends on fully pureeing the soup.
Avoid boiling after adding cream: This prevents curdling and maintains a silky consistency.
For extra flavor: Add a splash of white wine before simmering or a squeeze of lemon at the end to brighten the taste.

Variations & Customizations

Vegan option: Use olive oil and coconut or oat milk instead of butter and cream.
Chunky style: Blend only half the soup, leaving some texture.
Loaded version: Top with shredded cheese, scallions, and crispy onions.
Herb twist: Swap thyme for rosemary, tarragon, or dill for a fresh spin.
Add greens: Stir in spinach or kale at the end for added nutrients.

Serving Suggestions

Serve with warm crusty bread, baguette slices, or garlic toast.
Pair with a fresh green salad for a balanced meal.
For an elegant touch, serve in small bowls or cups as a starter for a dinner party.
Drizzle with truffle oil or sprinkle with Parmesan shavings for a gourmet twist.

Storage & Reheating

Refrigerate: Store in an airtight container for up to 4 days.
Freeze: Cool completely before freezing for up to 3 months. Thaw in the fridge overnight before reheating.
Reheat: Warm gently on the stove over low heat, stirring occasionally. Add a splash of broth or milk if it thickens too much.
