Ingredients

• 3 large (white and light green parts only, sliced) leeks
• 1 large (diced) yellow onion
• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 2 medium (peeled and diced) potatoes
• 2 cloves (minced) garlic
• 4 cups chicken or vegetable stock
• 1 cup heavy cream
• 1 teaspoon (adjust to taste) salt
• 0.5 teaspoon (adjust to taste) ground black pepper
• 2 tablespoons (chopped, for garnish) fresh parsley
• 0 (optional, for serving) crusty bread

Directions

Step 1

Prepare the leeks by trimming off the dark green leafy tops and roots. Slice the white and light green parts into thin rounds, then rinse thoroughly under cold water to remove any dirt.

Step 2

Heat the butter and olive oil in a large pot over medium heat.

Step 3

Add the diced onion and cook, stirring occasionally, for 5–7 minutes until softened and translucent.

Step 4

Stir in the sliced leeks and cook for another 5 minutes until softened and fragrant.

Step 5

Add the minced garlic and cook for 1 minute, stirring constantly, to prevent burning.

Step 6

Add the diced potatoes and pour in the chicken or vegetable stock. Bring the mixture to a boil, then reduce the heat to a simmer. Cover and cook for 20–25 minutes, or until the potatoes are tender.

Step 7

Using an immersion blender, carefully puree the soup until smooth and creamy. Alternatively, let the soup cool slightly and blend in batches in a countertop blender.

Step 8

Return the pot to low heat and stir in the heavy cream. Season with salt and pepper to taste.

Step 9

Garnish with chopped fresh parsley and serve with crusty bread, if desired.
