By charlotteh371

Ingredients

• 2 tbsp. unsalted butter
• 2 medium leeks, sliced
• 12 oz. celery root, peeled and cut into small cubes (about 2 3/4 cups)
• 9 oz. russet potato, peeled and cut into small cubes (about 1 3/4 cups)
• 3 cups chicken broth
• 1/2 tsp. kosher salt
• 1/4 tsp. black pepper
• 1/2 cup whole milk
• 1 tsp. Dijon mustard
• 1/4 cup heavy cream
• 1 tbsp. sliced fresh chives

Preparation

Step 1

Melt butter in a large saucepan over medium heat. Add leeks, and cook, covered, stirring often, until softened, 4 to 6 minutes. Add celery root and potato; cook, covered, stirring often, until vegetables begin to soften, about 3 minutes.
2. Stir in broth, salt and pepper. Bring to a boil, and reduce heat to medium-low to maintain a simmer. Cover, and cook until vegetables are tender, 15 to 20 minutes.
3. Carefully transfer soup to a blender. Remove center piece of blender lid (to allow steam to escape); secure lid on blender. Process until smooth. Return soup to pan over medium-low heat. Stir in milk and mustard.
