Creamy Asparagus Soup

From the archives, first posted 2007.

Spring here means strawberries and rhubarb, sweet peas and asparagus, and dreams of the summer bounty to come. Asparagus are everywhere, big, fat, and fresh. And yes, although we can get them all year round, I’m especially happy to eat them in Spring. Not only are they likely to have been grown in the same Hemisphere, and could even be local, their very abundance signals the renewal of the season and a good-bye to Winter. Here is a fresh and easy asparagus soup recipe, a perfect excuse to buy more than one bunch.

  • Prep: 15 minutes
  • Cook: 30 minutes
  • Yield: Serves 4-6.

Ingredients

  • 2 lbs asparagus, trimmed of woody stem bottoms
  • 1 large yellow onion, chopped (1 1/2 to 2 cups chopped)
  • 3 Tbsp unsalted butter
  • 4 cups chicken stock
  • 1 cup water
  • Leaves of 2 sprigs of fresh thyme
  • 2 Tbsp chopped fresh parsley
  • 1/4 cup heavy cream
  • 1 Tbsp dry vermouth
  • A squeeze of fresh lemon juice
  • Salt and pepper

Method

1 Cut tips from the asparagus 1 1/2 inches from top and halve tips lengthwise if thick. Reserve for garnish. Chop the remaining asparagus stalks into 1/4-inch rounds.

2 Melt the butter in a 4 to 5 quart pot on medium heat. Add the onions and cook until translucent, about 5 minutes. Add the chopped asparagus (not the spear tips) to the onions. Sprinkle with salt and pepper to taste. Cook another 5 minutes.

3 Add the broth, water, and thyme to the pot. Increase the heat to a boil, then reduce to a simmer. Simmer, covered, until the asparagus are tender, 10 to 15 minutes. At the end of cooking, stir in the chopped parsley.

4 While the soup is cooking, blanche the asparagus tips in a small pot of boiling, salted water (about 1 1/2 teaspoons of salt per quart of water), until the tips are just tender, about 2-4 minutes, depending on the size of the asparagus. Drain. Rinse with cool water to stop the cooking. Set aside.

5 Use an immersion blender to blend the soup until smooth. (If you use an upright blender, work in small batches, fill no more than a third the blender bowl at a time, and hold down the lid while blending.) For a creamy texture, if you want, press the puréed soup through a sieve or food mill. Stir in the cream. Stir in the vermouth and a squeeze of lemon juice. Season with salt and pepper to taste.

Garnish with asparagus tips.
