Time-saver tip: Cook up a double batch and freeze half for another dinner.
1 tablespoon butter
1 cup diced potato
1/2 cup thinly sliced green onions (scallions)
1 teaspoon minced garlic
1/2 teaspoon salt
1/4 teaspoon dried thyme or oregano leaves
1/4 teaspoon ground black pepper
11/2 pounds white leeks, sliced (about 9 cups)
1 cup white wine or water
11/2 cups low fat milk
In a large saucepan over medium-high heat, melt butter. Add potatoes, onions, garlic, salt, thyme and pepper; cook, stirring often, until onions just begin to brown, about 5 minutes. Add leeks, broth, and wine; bring to a boil; cook for 1 minute. Using a slotted spoon, remove 1 cup of the vegetables; set aside. In a blender or food processor, place half of remaining soup from the saucepan; puree until smooth; remove to a bowl; repeat with remaining mixture; return entire pureed mixture to saucepan; stir in milk and reserved vegetables. Simmer just until heated through, about 5 minutes. If desired, garnish with parsley.
