Chestnut and Mushroom Soup: A Taste of Autumn

There’s something magical about the first whiff of woodsmoke in the autumn air, the crunch of leaves underfoot, and the comforting warmth of a bowl of soup. One autumn, while visiting an old friend in the French countryside, I stumbled upon a tiny farmers market overflowing with earthy treasures. The scent of roasting chestnuts mingled with the damp aroma of wild mushrooms, instantly transporting me to a place of rustic charm and culinary delight. I purchased a bounty of both, determined to recreate the feeling in a bowl – and this chestnut and mushroom soup is the result, a fragrant reminder of crisp air and cozy evenings.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 24-34 minutes
• Total Time: 39-49 minutes
• Servings: 4
• Dietary Type: Vegetarian (easily Vegan)

Ingredients

• 1 tablespoon extra virgin olive oil
• 2 shallots, finely chopped
• 1 garlic clove, minced
• 1 leek, white and light green parts only, thinly sliced and well rinsed
• 3 tablespoons brandy (optional, or 3 tablespoons warm water)
• 1 lb chestnuts, vacuum-packed or jarred, patted dry
• 1 lb mixed mushrooms, such as cremini, shiitake, and oyster
• 1 pinch chili powder (optional)
• 6 cups vegetable stock
• Salt, to taste
• 2 tablespoons balsamic vinegar
• Fresh parsley, chopped, for garnish
• Freshly ground pepper, for garnish

Equipment Needed

• Large soup pot or Dutch oven
• Wooden spoon
• Immersion blender (or regular blender)
• Cutting board
• Sharp knife

Instructions

1. Heat the olive oil in a large soup pot or Dutch oven over medium heat.
2. Add the shallots, garlic, and leek. Cook for 5 minutes, stirring regularly, until softened and translucent. Be careful not to brown the garlic, as this can make the soup bitter.
3. Deglaze the pot with brandy, if using. If you prefer to omit the alcohol, use 3 tablespoons of warm water. Pour in the brandy or water and scrape the bottom of the pot with a wooden spoon to loosen any browned bits. This adds depth of flavor to the soup.
4. If you are using vacuum-packed or jarred chestnuts, pat them dry with paper towels. This will help them brown slightly.
5. Add the chestnuts to the pot and cook for 4 minutes, stirring gently from time to time, until the chestnuts are lightly golden. This step enhances their nutty flavor.
6. Reserve two mushrooms for garnish. Slice the remaining mushrooms and add them to the pot.
7. Add the chili powder, if desired.
8. Pour in the vegetable stock and season with salt to taste.
9. Bring to a simmer, cover, lower the heat to medium-low, and cook for 20-30 minutes, or until the vegetables are very soft.
10. Let the soup cool for a few minutes. This makes blending safer.
11. Puree the soup using an immersion blender until the soup is smooth with just a few remaining chunks. Alternatively, you can carefully transfer the soup to a regular blender in batches and blend until smooth. Be cautious when blending hot liquids.
12. Stir in the balsamic vinegar, taste, and adjust the seasoning as needed. The balsamic vinegar adds a touch of acidity that balances the richness of the chestnuts and mushrooms.
13. (The soup can be made a day ahead up to this point). Reheat gently before serving.
14. Cut the reserved mushrooms in slices, and chop the parsley leaves roughly.
15. Ladle the soup into bowls. Plop a mushroom slice on the surface of each bowl, sprinkle with parsley and a touch of freshly ground pepper, and serve immediately.

Expert Tips & Tricks

• For a richer flavor, use homemade vegetable stock.
• If you can find fresh chestnuts, roast them yourself for an even deeper, nuttier flavor. Score the chestnuts with an X, then roast at 400°F (200°C) for 20-30 minutes, or until the shells are cracked and the chestnuts are tender. Peel while still warm.
• Don’t overcrowd the pot when cooking the vegetables. If necessary, cook them in batches.
• To prevent the soup from splattering while blending, start on a low speed and gradually increase it.
• If you don’t have an immersion blender, you can use a regular blender. Be sure to vent the lid to allow steam to escape.
• For a creamier soup, add a splash of coconut milk or cashew cream after blending.
• Taste and adjust the seasoning as you go. The amount of salt needed will depend on the saltiness of your vegetable stock.

Serving & Storage Suggestions

Serve the chestnut and mushroom soup hot, garnished with sliced mushrooms, chopped parsley, and freshly ground pepper. A swirl of cream or a drizzle of truffle oil adds a touch of elegance. This soup pairs well with crusty bread, a simple salad, or a grilled cheese sandwich.

Leftover soup can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze the soup in individual portions for up to 2 months. Reheat gently on the stovetop or in the microwave.
