- 2 tablespoons unsalted butter
- 1 1/4 cups chopped yellow onions
- 1 1/2 cups chopped parsnips
- 3 tablespoons minced celery
- 1 teaspoon minced garlic
- 4 to 6 fresh thyme sprigs, tied together
- 2 pounds turnips, peeled and diced
- 3 cups chicken stock or canned, low sodium chicken broth

- Melt butter in a large saucepan over medium-high heat and add onions, parsnips, and celery. Cook until vegetables are lightly caramelized around the edges, 4 to 6 minutes.
- Add garlic and thyme and cook, stirring, until garlic is fragrant, 1 to 2 minutes.
- Add turnips, stocks, salt, and pepper and bring to a boil. Reduce heat just to a simmer and cook until turnips are very tender, 20 to 25 minutes.
- Remove thyme and add heavy cream, if using.
- Using an immersion blender (or in batches in a blender), puree soup until very smooth.
- Rewarm if necessary, then serve in small bowls, garnished with a dollop of sour cream, a pinch of chives, and parsnip chips.
