1 1/2 pounds (5 cups) Yukon gold or russet potatoes, cut into 1-inch pieces
4 medium leeks, coarsely chopped
1 teaspoon salt
1/4 teaspoon pepper
1 (32-ounce) box (4 cups) chicken broth
3 tablespoons chopped fresh chives
2 teaspoons prepared horseradish
Chopped fresh chives, if desired
Melt butter in 4-quart saucepan until sizzling; add potatoes, leeks, salt and pepper. Cook over medium heat, stirring occasionally, 8-10 minutes or until leeks are softened.
Add chicken broth. Increase heat to medium-high; cook 8-10 minutes or until mixture comes to a boil. Reduce heat to low. Cover; cook 25-27 minutes or until potatoes are tender. Stir in half & half.
Place 3 cups soup in 5-cup blender container or food processor bowl fitted with metal blade. Cover; blend until smooth. Pour into large serving bowl; repeat with remaining soup. Stir in 3 tablespoons chives and horseradish. Garnish with chopped fresh chives, if desired.
Leeks are grown in sandy soil, so it’s important to rinse them well. Slice lengthwise and run water between the layers so all the sand is washed away. Chop the white and tender green parts of the leeks.
Soup can be served chilled. Prepare as directed above. After blending, refrigerate for at least 2 hours. Before serving, stir in 1 cup additional half & half if soup is too thick.
