Ingredients:
- 2 tablespoons unsalted butter (30g)
- 1 medium yellow onion, chopped (about 1 cup) (150g)
- 2 cloves garlic, minced (about 1 teaspoon) (6g)
- 1.5 pounds fresh asparagus, ends trimmed and chopped (reserve tips for garnish) (680g)
- 4 cups vegetable broth or chicken broth (950ml)
- 1/2 cup heavy cream (120ml) (optional)
- 1/4 cup dry white wine (60ml) (optional)
- 1 tablespoon lemon juice (15ml)
- Salt and freshly ground black pepper to taste
- Optional garnishes: reserved asparagus tips, a swirl of cream, fresh chives, croutons
Instructions:
- Melt butter in a large pot. Add onion and garlic and sauté until softened but not browned.
- Add the chopped asparagus (except the tips you've reserved) and broth to the pot. Bring to a boil, then reduce heat and simmer until the asparagus is tender.
- Stir in the broth and bring to a simmer, then reduce the heat to low. Cover and cook for about 15 minutes, or until the asparagus is tender.
- Using an immersion blender, blend the soup until smooth. Alternatively, carefully transfer the soup to a regular blender and blend in batches.
- Stir in the heavy cream (if using) and lemon juice. Season with salt and pepper to taste.
- While the soup is blending, quickly blanch the reserved asparagus tips in boiling water for 2-3 minutes, until bright green and tender-crisp. Drain and set aside.
- Ladle the soup into bowls. Garnish with the blanched asparagus tips, a swirl of cream (if desired), and fresh chives. Serve immediately.
