Here’s a summary of a classic Potato Leek Soup recipe along with the key steps:

Preparation: Clean the leeks thoroughly to remove any dirt or sand.
Sauté the Leeks: In a large pot, melt the butter over medium heat. Add the leeks and cook until softened, about 5-7 minutes.
Add Potatoes and Broth: Add the diced potatoes and broth to the pot. Bring to a boil, then reduce the heat and simmer until the potatoes are tender, about 20-25 minutes.
Blend the Soup: Use an immersion blender to puree the soup until smooth. Alternatively, you can transfer the soup in batches to a blender.
Add Cream: Stir in the heavy cream and season with salt and pepper to taste. Heat the soup gently, without bringing it to a boil.
Serve: Ladle the soup into bowls and garnish with chopped chives if desired.
