Ingredients
1
1/2 pound large leeks (white and pale green parts only), thinly sliced (about 2 1/2 cups)
1
1/2 pounds Yukon Gold potatoes, peeled, cut into 2-inch pieces
1
pound zucchini, cut into 1-inch rounds
4
1/2 cups (or more) canned low-salt chicken broth
Directions
1.
Melt butter in heavy large pot over medium heat. Add leeks and garlic; sauté until tender, about 6 minutes. Add potatoes and zucchini; sauté 5 minutes. Add 4 1/2 cups broth and bring to a boil. Reduce heat and simmer until potatoes are tender, about 15 minutes. Cool 30 minutes.
2.
Working in batches, puree soup in blender. Transfer soup to large bowl. Mix in half and half. Season to taste with salt and pepper. Cover and refrigerate until cold, about 4 hours. (Can be made 2 days ahead. Keep refrigerated. Before serving, thin with additional broth, if necessary.)
3.
Ladle soup into bowl. Sprinkle with chives and serve.
