I've always been partial to vichyssoise, that classic cold potato soup created by New York Ritz-Carlton chef Louis Diat in the summer of 1917. I also adore globe artichokes, so I thought, "Why not combine the two in an easy summer soup?" Frozen artichokes shorten prep time, and marinated artichoke hearts boost the flavor. Prep: 10 minutes; Cook: 40 minutes; Chill: 2 hours.
1 (9-ounce) package frozen artichoke hearts
1 baking potato, peeled and cubed (about 12 ounces)
8 large green onions, trimmed and thinly sliced
2 cups vegetable broth
1 1/2 cups half-and-half, divided
1 (12-ounce) jar marinated artichoke hearts, drained and liquid reserved, if desired
1 1/2 cups milk
3/4 teaspoon salt
1/4 teaspoon freshly ground pepper
3 tablespoons coarsely chopped fresh chives
How to Make It
Bring first 4 ingredients to a boil in a large nonreactive saucepan over high heat. Reduce heat, cover, and simmer 40 to 45 minutes or until tender.
Puree until smooth in 2 batches in a food processor, adding 1/4 cup half-and-half and half the marinated artichoke hearts to each batch. Transfer each batch to a large nonreactive pitcher.
Stir in remaining 1 cup half-and-half, milk, salt, and pepper. For extra tartness, if desired, stir in 1 to 2 tablespoons reserved artichoke liquid. Cover and chill at least 2 hours before serving.
Whisk well, ladle into chilled soup bowls, and sprinkle with chopped chives.
