Lemony Asparagus-Dill Soup
Total Time: 50
Yield: 2 quarts, 8 to 10 servings
This Lemony Asparagus-Dill Soup Recipe -- an adaptation of the classic Greek egg-and-lemon soup -- can be made a day ahead of time and served warm or cold. For this menu, I prefer to serve it warm.
- 3 pounds thin asparagus
- 4 cups chicken broth
- 4 cups plus 2 cups water
- 1/2 teaspoon salt
- 3 tablespoons butter
- 1-1/2 cups chopped celery
- 1-1/2 cups finely chopped onion
- 1 cup chopped leeks (cleaned well), white parts only
- Salt and freshly ground black pepper, to taste
- 3 eggs
- 1/4 cup plus 2 tablespoons fresh lemon juice
- 1/4 cup snipped fresh dill
- Garnish: dill sprigs and asparagus tips
Wash asparagus. Break off woody ends of asparagus and reserve, then cut tips off asparagus spears and reserve. Cut asparagus stalks into 1-inch pieces. (If you use thick asparagus, peel the bottom 3 inches of the stalk with a vegetable peeler first, then reserve the peels along with the woody ends.) In a saucepan over high heat, place asparagus ends (and peels) and chicken broth. Cover, bring to a boil, and then immediately remove mixture from heat and let rest 15 minutes. Strain broth and reserve. Discard asparagus ends (and peels).
Place 4 cups of water and 1/2 teaspoon salt in a small saucepan. Bring to a boil, then blanch the asparagus tips 2 minutes, or until bright green and barely cooked through. Remove tips from hot water and plunge into a bowl of ice water until chilled. Drain and reserve to use as garnish for the soup.
In a large soup pot over medium heat, melt butter and add chopped celery, onions, and leeks. Saute until softened, about 6 minutes. Season with salt and pepper to taste. Add asparagus stalk pieces; stir. Add infused chicken broth and 2 cups water. Increase heat to high and bring to a boil, then reduce heat to medium-low and simmer, covered, about 5 minutes, until asparagus is tender. In a blender, puree soup in batches. Return pureed soup to the pot and allow to cool about 5 minutes, or until lukewarm.
In a small bowl that can withstand heat, whisk together eggs and 1/4 cup lemon juice until creamy and well mixed. Slowly add 1 cup of the slightly cooled soup, whisking constantly. Pour egg-soup mixture back into the soup pot, whisking constantly. Cook soup over low heat, whisking constantly, until soup is thickened slightly and the temperature reaches 160 degree on an instant-read thermometer. Do not allow soup to boil. Whisk in snipped dill and additional 2 tablespoons lemon juice. Add salt and pepper to taste.
Refrigerate soup in a covered container up to 24 hours. Reheat gently on low heat before serving. Place asparagus tips and a sprig of dill in the center of each bowl of soup as a garnish.
