White root vegetables do the talking in this rich and velvety soup that will leave you guessing it’s laden with cream. Well, guess again. This humble soup is light and healthy, thickened by parsnips and celery root with a good splash of milk. The sweet and nutty root vegetables are tempered by garlic and thyme for a well rounded and slurp-worthy bowl of goodness that promises to keep you warm in the cold weather.
Parsnip and Celery Root Soup
Feel free to change the ratio of veggies and/or add Jerusalem artichokes to the mix. Just be sure to keep the total weight at 2 pounds. Serves 4 to 6.
1 tablespoon extra-virgin olive oil
1 medium onion, chopped, about 1 cup
1 pound parnsips, peeled, cut into 3/4-inch chunks
1 pound celery root, peeled, cut into 3/4-inch chunks
3 cloves garlic, chopped
4 cups chicken stock
2 sprigs thyme
1/2 cup whole milk plus more to taste
1 teaspoon salt, or more to taste
1/2 teaspoon freshly ground black pepper
Heat the oil in a soup pot over medium heat. Add the onion and sauté until translucent without coloring, about 3 minutes. Add the parsnips, celery root, and garlic. Sauté until the vegetables begin to soften, 2 to3 minutes. Add the chicken stock and thyme. Bring to a boil, then reduce heat to low. Cover and simmer until the vegetables are very soft, 25 to 30 minutes. Remove the thyme sprigs. Carefully transfer the soup to a food processor (or use an immersion blender) and purée until smooth. Return to the soup pot. Add the milk, salt and pepper. If too thick, add more milk to your desired consistency and taste for seasoning. Serve warm.
