Potato Leek Soup is a comforting, creamy dish perfect for chilly days or when you crave something warm and soothing. The combination of tender potatoes and mild leeks creates a velvety texture, while a hint of garlic and fresh herbs enhances the flavor. This soup is easy to prepare and makes for a satisfying meal, whether you're serving it as a starter or the main course.
Prepare the Vegetables. Begin by washing the leeks thoroughly to remove any dirt or sand. Slice them thinly, using only the white and light green parts. Peel and dice the potatoes into small, even cubes.
Cook the Aromatics. In a large pot, heat the olive oil and butter over medium heat. Add the chopped onion, sliced leeks, and minced garlic. Sauté for about 5-7 minutes, until the leeks are soft and the onion is translucent.
Add the Potatoes and Broth. Stir in the diced potatoes and season with salt and pepper. Pour in the vegetable broth and bring to a boil. Once boiling, reduce the heat to a simmer and cook for 20-25 minutes, or until the potatoes are tender.
Blend the Soup. Use an immersion blender to puree the soup until smooth. If you don't have an immersion blender, carefully transfer the soup in batches to a regular blender and puree until smooth. Return the soup to the pot.
Finish with Cream. If you desire a richer soup, stir in the heavy cream. Taste and adjust seasoning with additional salt and pepper if needed.
Serve. Ladle the soup into bowls and garnish with fresh chives or parsley. Serve hot with crusty bread on the side.
Replace the heavy cream with half-and-half or full-fat coconut milk for a dairy-free option. Try adding a bay leaf to the broth as it simmers, removing it before blending. Include other vegetables like carrots or celery for additional flavor and texture.
