- 1 1/2 lb. asparagus
- 4 Tbs. (1/2 stick) plus 2 tsp. unsalted butter
- 1 yellow onion, diced
- 3 garlic cloves, minced
- 1/4 cup dry vermouth
- 3 cups chicken stock, plus more as needed
- Salt and freshly ground pepper, to taste
- 3/4 cup heavy cream
In a heavy soup pot over medium heat, melt the 4 Tbs. (1/2 stick) butter. Add the onion and garlic and sauté, stirring occasionally, until tender and translucent, 3 to 4 minutes. Add the vermouth and cook until most of the liquid has evaporated. Add the chopped asparagus and the 3 cups stock. Season with salt and pepper. Bring to a simmer, then reduce the heat to medium-low. Cover and cook until the asparagus is tender, about 20 minutes.
Using an immersion blender, puree the soup until smooth, about 2 minutes. Pass the soup through a chinois into a clean saucepan. Stir in the cream plus more stock if needed to reach the desired consistency. Season with salt and pepper. Set the pan over low heat and reheat the soup to serving temperature.
In a small sauté pan over medium heat, melt the 2 tsp. butter. Add the reserved asparagus tips and cook until just tender, about 2 minutes. Ladle the soup into warmed bowls, garnish with the asparagus tips and serve immediately. Serves 4.
