🥗 Ingredients

The Soup Base

  • 18 ounces Roasted Chestnuts (peeled; vacuum-packed or jarred are excellent for convenience)
  • 3 tablespoons Unsalted Butter (high-quality European style preferred)
  • 1 Yellow Onion (medium, finely diced)
  • 1 large Leek (white and light green parts only, cleaned and sliced)
  • 1 Celery Stalk (finely chopped)
  • 2 Garlic Cloves (minced)

Liquids & Aromatics

  • 1/2 cup Dry White Wine (such as Sauvignon Blanc or Pinot Grigio)
  • 5 cups Chicken or Vegetable Stock (low-sodium, high-quality)
  • 3 sprigs Fresh Thyme (tied together with kitchen twine)
  • 1 Bay Leaf (dried)
  • 1/2 cup Crème Fraîche (plus extra for swirling)
  • 1 teaspoon Kosher Salt (or to taste)
  • 1/2 teaspoon Black Pepper (freshly cracked)
  • 1/8 teaspoon Nutmeg (freshly grated)

For Garnish

  • 8-10 Fresh Sage Leaves (fried until crisp in a little butter)
  • 1 teaspoon White Truffle Oil (for drizzling)
  • 3-4 pieces Reserved Chestnuts (crumbled)

👨‍🍳 Instructions

  1. 1

    In a large Dutch oven or heavy-bottomed pot, melt the 3 tablespoons of butter over medium heat until it begins to foam.

  2. 2

    Add the diced onion, sliced leeks, and celery. Sauté for 8-10 minutes, stirring occasionally, until the vegetables are soft and translucent but not browned.

  3. 3

    Stir in the minced garlic and cook for just 60 seconds until fragrant, being careful not to let it burn.

  4. 4

    Add the roasted chestnuts to the pot (reserving 3-4 for garnish). Stir them into the butter and vegetables for 2 minutes to toast them slightly and release their oils.

  5. 5

    Pour in the white wine to deglaze the pan, scraping up any flavorful bits from the bottom. Let the wine simmer until it has reduced by half.

  6. 6

    Add the stock, thyme sprigs, and bay leaf. Bring the mixture to a gentle boil, then immediately reduce the heat to low.

  7. 7

    Cover the pot and simmer for 20-25 minutes. This allows the chestnuts to soften completely and the flavors to marry.

  8. 8

    Remove the pot from the heat. Carefully fish out and discard the thyme sprigs and the bay leaf.

  9. 9

    Using an immersion blender, puree the soup until it is completely smooth and velvety. If using a standard blender, work in small batches and hold the lid down with a towel to prevent steam pressure buildup.

  10. 10

    Return the pureed soup to the pot over low heat. Stir in the crème fraîche, salt, black pepper, and freshly grated nutmeg.

  11. 11

    Taste and adjust seasoning. If the soup is too thick, add a splash more stock until you reach your desired silky consistency.

  12. 12

    Ladle the hot soup into warmed bowls. Garnish with a swirl of crème fraîche, a few crumbled chestnuts, a fried sage leaf, and a tiny drizzle of truffle oil.

💡 Chef's Tips

If using fresh chestnuts, score an 'X' on the flat side and roast at 400°F for 20 minutes before peeling while warm. For an even silkier texture, pass the pureed soup through a fine-mesh sieve (chinois) before adding the cream. Don't skip the nutmeg; it provides a subtle warmth that bridges the sweetness of the chestnuts and the savory stock. If the soup tastes flat, add a teaspoon of lemon juice or sherry vinegar at the end to brighten the flavors. To make it vegan, substitute the butter with olive oil and the crème fraîche with full-fat coconut milk or cashew cream.

🍽️ Serving Suggestions

Serve with warm, crusty sourdough bread or buttery brioche croutons. Pairs beautifully with a glass of crisp Chardonnay or a dry Amontillado Sherry. Accompany with a simple arugula salad dressed in a light lemon vinaigrette to cut through the richness. For a main course, serve alongside roasted duck breast or a mushroom risotto. Excellent as a 'sipping' appetizer served in small espresso cups for holiday parties.
