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. The soup holds well overnight. Reheat it gently and add the butter at the end so the finish stays clean.

The Story Behind This Dish

In Sardinia, chestnut and wild fennel soup belongs to the colder months, especially where chestnuts are part of the inland kitchen. I make it plain: chestnuts, fennel, onion, celery, parsley, water, and a little butter at the end.

The work is in the chestnuts. I score them, blanch them, and peel them while they are still warm. Once they are in the pot, I let the soup simmer quietly until the chestnuts soften and start to break into the broth.

Wild fennel gives the soup its Sardinian marker. If I only have fennel fronds, I use them and accept a milder pot.

How I Serve It

I serve this hot, without blending it smooth. The chestnuts should stay partly whole and partly broken down. Add the butter off the heat, then wait a minute before ladling so the broth settles.
