Instructions

  1. Peel the chestnuts. Score each one with a knife, blanch in boiling water for 2 minutes, then peel off both the outer shell and the inner skin.

    Tip: Peel chestnuts while still warm—once they cool the inner skin sticks.
  2. Wash and roughly chop the wild fennel. Chop the onion, celery, and parsley.

  3. Heat olive oil in a large pot over medium heat. Add the chopped onion, celery, and parsley. Sauté for 5 minutes until softened.

  4. Add 2 liters of water, salt, and pepper. Bring to a boil.

  5. Add the peeled chestnuts and wild fennel. Reduce heat and simmer for about 1 hour, stirring occasionally. If the soup gets too thick, add more water.

    Tip: The chestnuts should be soft enough to break apart when pressed with a spoon.
  6. Remove from heat and stir in the butter until melted. Serve hot.

Storage & Meal Prep

Refrigerate for up to 3 days. The soup will thicken as it sits—thin with water when reheating. Freezes well for up to 2 months.

Variations

  • With Pancetta: Dice 100g of pancetta and fry it with the onion and celery at the start for a meatier version.
  • Blended Version: Blend half the soup before serving for a creamier texture while keeping some chestnut pieces intact.

FAQ

Can I use regular fennel instead of wild fennel?

Yes. Use the fronds and some of the tender stalks. The flavor will be milder than wild fennel but still works well.

Do I need to soak chestnuts before peeling?

No. Scoring and blanching them briefly in boiling water is enough to loosen both shells and inner skins.

Can I make this soup ahead of time?

Yes. It reheats well and the flavors improve overnight. Add the butter fresh when reheating.
