Prepare the Potatoes
- Peel the potatoes and cut them into evenly sized chunks.Try to keep the pieces similar in size so they cook at approximately the same rate.
Sauté the Leeks and Onion
- Melt the butter in a large heavy-bottomed pot or Dutch oven over medium heat.Add the sliced leeks and chopped onion.Cook gently for approximately 7–10 minutes, stirring occasionally, until the vegetables become soft and fragrant.Avoid browning them heavily because the goal is to develop their delicate sweetness.

Add the Cream
- Return the blended soup to low heat if necessary.Slowly stir in the heavy cream.Heat gently for approximately 2–3 minutes.Do not allow the soup to boil vigorously after adding the cream.
Garnish and Serve
- Ladle the hot soup into serving bowls.Garnish with fresh parsley, thyme leaves, homemade croutons, a drizzle of cream, or freshly cracked black pepper.Serve immediately with warm crusty bread or garlic toast.
Notes

- Leeks: Use the white and light green portions for the best flavor and texture.
- Cream: Heavy cream gives the richest result, but whole milk can be used for a lighter soup.
- Broth: Vegetable broth keeps the soup vegetarian, while chicken broth adds extra savory depth.
- Texture: The soup can be completely smooth or partially blended if you prefer some potato pieces.
