Ingredients

Scale
  • 1 pound (450g) fresh asparagus, trimmed and cut into 2-inch pieces
  • 2 tablespoons unsalted butter
  • 1 medium onion, finely chopped
  • 2 garlic cloves, minced
  • 4 cups (950 ml) vegetable or chicken broth (low-sodium preferred)
  • ½ cup (120 ml) heavy cream (can substitute full-fat coconut milk for dairy-free)
  • Zest of 1 lemon
  • 1 tablespoon fresh lemon juice
  • ½ cup (120 ml) crème fraîche, plus extra for garnish
  • Salt and freshly ground black pepper to taste
  • Fresh herbs like chives or tarragon for garnish (optional)

Instructions

  1. Rinse and trim about 1 pound (450g) of fresh asparagus, cutting into 2-inch pieces. Set aside the tender tips separately.
  2. In a large heavy-bottomed pot, melt 2 tablespoons of unsalted butter over medium heat. Add 1 finely chopped medium onion and sauté for about 5 minutes until translucent and soft.
  3. Add 2 minced garlic cloves and cook for another minute until fragrant, being careful not to brown the garlic.
  4. Add the asparagus stalks (reserve the tips) and pour in 4 cups (950 ml) of vegetable or chicken broth. Bring to a gentle boil, then reduce to a simmer and cook uncovered for 12-15 minutes until asparagus is tender.
  5. Remove from heat and puree the soup using an immersion blender until smooth and creamy. If using a regular blender, blend in batches and return to the pot.
  6. Stir in ½ cup (120 ml) heavy cream, lemon zest, and 1 tablespoon fresh lemon juice. Season with salt and freshly ground black pepper to taste. Warm gently without boiling.
  7. In a small pan, lightly sauté the reserved asparagus tips in a teaspoon of butter or olive oil for 2-3 minutes until tender but still bright green. Alternatively, steam them.
  8. Ladle the soup into bowls and top each with a dollop of crème fraîche. Garnish with sautéed asparagus tips and fresh herbs if desired.

Notes

If soup is too thick after blending, thin with a splash of broth or water. Add lemon crème fraîche fresh at serving time for best flavor. For vegan version, substitute butter with olive oil, heavy cream with coconut milk, and crème fraîche with coconut yogurt or cashew cream. Frozen asparagus can be used but add earlier in cooking.
