Why This Recipe Works
Ingredients for Recipe
Leeks (3 medium): Make sure to clean them thoroughly. Leeks grow in sandy soil, so rinse each layer well to remove dirt.
Butter (2 tbsp): Use unsalted butter for better control over the saltiness of the soup.
Garlic (2 cloves, minced): Adds depth to the flavor. Be careful not to let it brown too much to avoid bitterness.
Potatoes (2 medium, peeled and diced): They help to thicken the soup and give it that creamy texture without the need for too much cream.
Vegetable or Chicken Broth (4 cups): Choose a high-quality broth for the best flavor. You can also use homemade stock for a more intense taste.
Heavy Cream (1 cup): For that silky-smooth finish. Adjust the amount to your preferred creaminess.
Salt and Pepper: To taste. Be generous with the seasoning, as leeks need a little salt to bring out their full flavor.
Fresh Thyme (1 sprig): The earthy aroma of thyme pairs beautifully with leeks, enhancing the overall experience.
Step-by-Step Instructions
- Prepare the leeks: Trim the root and dark green tops of the leeks. Slice the white and light green parts thinly. Thoroughly rinse the slices in cold water to remove any sand.
- Sauté the leeks and garlic: In a large pot, melt the butter over medium heat. Add the leeks and sauté until softened, about 5-7 minutes. Add the garlic and cook for an additional minute.
- Add potatoes and broth: Stir in the diced potatoes and vegetable broth. Bring to a boil, then reduce heat and let simmer for 20-25 minutes, or until the potatoes are tender.
- Blend the soup: Use an immersion blender to purée the soup until smooth. Alternatively, you can transfer the soup to a blender in batches.
- Stir in the cream: Once blended, return the soup to low heat and stir in the heavy cream. Season with salt and pepper to taste. Let the soup heat through for 3-5 minutes.
- Finish and serve: Ladle the soup into bowls and garnish with fresh thyme or a swirl of extra cream. Serve immediately.
Chef’s Insight: Don’t let the garlic brown too much, as it can become bitter.
Pro Tips & Common Mistakes to Avoid
High heat can cause the cream to curdle. Keep the heat low after adding it.
If you prefer a more rustic soup, mash the potatoes slightly before blending.
Leeks should soften, not brown. This preserves their delicate flavor.
Leeks need salt to bring out their natural sweetness, but be careful not to overdo it.
Serving, Nutrition, Storage, Reheating & Freezing Guide
This soup can be served as a stand-alone meal or as a starter to a hearty dinner. It pairs well with a slice of crusty bread or a light salad. For storage, let the soup cool completely before transferring it to an airtight container. It will stay fresh in the fridge for 3-4 days. When reheating, warm gently over low heat to avoid separating the cream. For freezing, allow the soup to cool and store in an airtight container for up to 3 months. To reheat, simply thaw overnight and warm on the stove.

Notes
- Leeks: Be sure to clean the leeks thoroughly, as they often contain sand between the layers. Rinse them under cold water and pat dry before slicing.
- Butter vs. Oil: You can substitute butter with olive oil for a lighter version of this soup. Olive oil will still give it a smooth texture but with a different flavor profile.
- Cream Alternatives: For a lighter or dairy-free version, substitute the heavy cream with coconut milk or a plant-based cream. The texture will be a bit different, but the soup will still be creamy and delicious.
- Potatoes: The potatoes help thicken the soup naturally. If you prefer a thinner consistency, you can reduce the amount of potatoes or use a little less cream.
- Serving: This soup is great on its own or served with a slice of crusty bread, a side salad, or a sprinkle of crispy croutons for added texture.
