Parsley-Root Soup With Truffled Chestnuts

• 1 1/2 cups chopped onion (1 large)
• 3 garlic cloves, chopped
• 5 tablespoons unsalted butter
• 3 pounds parsley root (about 4 1/2 pounds total with tops), tops discarded and root peeled and chopped
• 3 (4- to 5-inch) sprigs thyme
• 1 Turkish bay leaf or 1/2 California
• 1/2 teaspoon white pepper
• 6 cups water
• 3 cups reduced-sodium chicken broth
• 3 tablespoons extra-virgin olive oil
• 8 to 10 peeled roasted whole chestnuts (from a 7-ounce jar)

1. Cook onion and garlic in butter in a large heavy pot over medium heat, stirring occasionally, until onion is softened and golden, 6 to 8 minutes. Add parsley root, thyme, bay leaf, white pepper, and 3/4 teaspoon salt and cook, stirring occasionally, until parsley root begins to soften, 8 to 10 minutes. Add water and broth and simmer, partially covered, until parsley root is very tender, 30 to 40 minutes.
2. Discard thyme and bay leaf and stir in oil. Puree soup in batches in a blender until smooth (use caution when blending hot liquids), transferring to a bowl. If soup is too thick, thin to desired consistency with water. Season with salt, then return to cleaned pot to keep warm, covered, until ready to serve.
3. Shave chestnuts with an adjustable-blade slicer or sharp vegetable peeler as thinly as possible over each serving.
