Parsley-Root Soup with Truffled Chestnuts

This elegant parsley root soup offers a sophisticated alternative to traditional root vegetable recipes. The parsley root provides a delicate, earthy sweetness that sits somewhere between parsnip and celeriac, creating a velvet-smooth texture once blended. Infused with aromatic thyme and white pepper, the soup is finished with a drizzle of extra-virgin olive oil for a rich, savoury depth that feels indulgent yet remains light and balanced.

As a diabetes-friendly option, this nutritious dish is high in fibre and uses roasted chestnuts for a festive, nutty crunch without the need for heavy cream. The shaved chestnuts add a wonderful visual appeal, making it an ideal starter for a dinner party or a comforting autumn lunch. Serve it alongside a small portion of wholegrain bread for a complete, heart-healthy meal.

Ingredients for Parsley-Root Soup with Truffled Chestnuts

  • 240g chopped onion (1 large)

  • 3 garlic cloves, chopped

  • 5 tablespoons unsalted butter

  • 1.4kg parsley root (about 2.0kg 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 teaspoons white pepper

  • 1450ml water

  • 725ml reduced-sodium chicken broth

  • 45ml extra-virgin olive oil

  • 8 to 10 peeled roasted whole chestnuts (from a 200g jar)

How to make Parsley-Root Soup with Truffled Chestnuts

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 teaspoons 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.

Discard thyme and bay leaf and stir in oil. Purée 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.

Shave chestnuts with an adjustable-blade slicer or sharp vegetable peeler as thinly as possible over each serving.
