Description

This creamy Asparagus Soup is a fresh, healthy, and flavorful dish made with tender asparagus, fennel, and herbs. It delivers a silky texture without heavy cream, making it perfect for a light lunch or elegant appetizer.


Ingredients

Scale
  • 1 lb (450g) fresh asparagus, trimmed and chopped
  • 1 medium onion, diced (about 1 cup)
  • 2 cloves garlic, minced
  • 1 cup fennel, chopped
  • 1 medium potato, peeled and diced (about 1 cup)
  • 3 cups vegetable broth
  • 2 tablespoons olive oil
  • 1 tablespoon fresh tarragon, chopped (or 1 teaspoon dried)
  • 1 tablespoon lemon juice
  • 1/2 teaspoon salt (or to taste)
  • 1/4 teaspoon black pepper

Instructions

  1. Trim the woody ends off the asparagus and chop into small pieces. Dice the onion, fennel, and potato, and mince the garlic.
  2. Heat olive oil in a large pot over medium heat. Add the onion and fennel, sauté for 5–7 minutes until soft and fragrant.
  3. Add the garlic and cook for 1 minute, stirring constantly to avoid burning.
  4. Add the chopped potato and asparagus, stirring to combine with the aromatics.
  5. Pour in the vegetable broth and bring to a gentle boil.
  6. Reduce heat and simmer for 15–20 minutes, until vegetables are tender.
  7. Remove from heat and blend the soup using an immersion blender until smooth.
  8. Stir in tarragon and lemon juice, then season with salt and pepper.
  9. Return to low heat and warm gently before serving.
  10. Serve hot with optional garnish like herbs or a drizzle of olive oil.

Notes

  • Use fresh, bright green asparagus for best flavor.
  • For extra creaminess, add 1/4 cup coconut milk or heavy cream.
  • Adjust consistency by adding more broth if needed.
  • A squeeze of lemon juice helps balance flavors.
  • Store leftovers in the refrigerator for up to 3 days.
  • This soup can be frozen for up to 2 months without dairy additions.
