Chestnut Soup - Thao Bui

Chestnut soup is smooth, warm, and full of rich, nutty flavor.

It feels fancy, but it’s surprisingly easy to make at home.

The chestnuts become creamy as they cook, and the onion, garlic, and herbs add just the right amount of savory flavor.

This soup is perfect for a cozy lunch or a simple dinner.

Why I Love This Recipe

The first time I made chestnut soup was on a cool fall evening. I had a bag of cooked chestnuts and wanted something warm that felt comforting without being too heavy. After blending everything together, I couldn’t believe how creamy it became without needing lots of cream. Now it’s one of the soups I make every year when the weather turns cool.

What I love most:

It tastes rich but uses simple ingredients.
The chestnuts make the soup naturally creamy.
It is easy enough for weeknights but nice enough for guests.
It reheats beautifully the next day.
Every spoonful is smooth, cozy, and full of flavor.

Substitutions and Variations

Make Ahead Tips

Recipe

Step 1: Cook the Onion and Garlic

Melt 2 tablespoons unsalted butter with 1 tablespoon olive oil in a large soup pot over medium heat. Add 1 diced onion and cook for about 6 minutes until soft. Stir in 2 minced garlic cloves and cook for 1 more minute until fragrant.

Step 2: Add the Chestnuts and Broth

Add 14 ounces cooked peeled chestnuts, 4 cups chicken broth, 1 teaspoon fresh thyme leaves, 1 bay leaf, ½ teaspoon salt, and ¼ teaspoon black pepper. Stir well and bring the soup to a gentle boil.

Step 3: Simmer

Reduce the heat to low. Let the soup simmer for 20 minutes so the chestnuts become very soft and the flavors blend together. Remove the bay leaf.

Step 4: Blend the Soup

Blend the hot soup until completely smooth using an immersion blender or a blender. Return it to the pot if needed.

Step 5: Stir in the Cream

Pour in ½ cup heavy cream and stir until fully mixed. Heat gently for about 2 minutes. Do not let the soup boil.

Step 6: Garnish and Serve

Ladle the soup into round bowls. Top with 2 tablespoons chopped fresh parsley, fresh cracked black pepper, and chopped toasted chestnuts if using. Serve warm.

Why This Recipe Works (Quick Science)

Chestnuts are full of natural starch. As they simmer in the broth, the starch breaks down and thickens the soup. Blending the cooked chestnuts creates a smooth, creamy texture without needing lots of cream. Adding the cream at the end keeps it rich and silky.

Common Mistakes

Do not use raw chestnuts unless they are fully cooked first.
Do not boil the soup after adding the cream.
Blend until completely smooth for the best texture.
Remove the bay leaf before blending.
Taste the soup before serving because different broths have different amounts of salt.
