In this Rutabaga and Parsnip Soup recipe, rutabaga is first roasted with parsnips and carrots to bring out a little sweetness, then simmered with thyme, nutmeg, and cardamom for a resulting flavor that elevates this humble root vegetable to delicious new heights.
Place the rutabaga, parsnips, and carrots on a baking sheet. Toss with two tablespoons of olive oil and season with salt and pepper.
Roast for 30-35 minutes, tossing occasionally, until the vegetables are tender and slightly brown.
Meanwhile, heat the remaining tablespoon of olive oil in a heavy bottomed pot over medium high heat.
Add the onion, celery, and garlic along with a pinch of salt. Cook until the onion is tender, about 5-6 minutes.
Add the roasted vegetables to the pot, and pour in the vegetable stock. Add the thyme, nutmeg, cardamom, and salt and pepper to taste. Bring to a low boil, then cover the pot and simmer for 25-30 minutes.
Use and immersion blender or carefully transfer the soup to a standard blender and puree until smooth.
Stir in the coconut milk and cook for a few minutes until heated through. Season the soup with more salt and pepper to taste.
Ladle the soup into bowls and garnish with green onions, ground nutmeg, and a drizzle of olive oil.
Notes
To make a curly green onion garnish: thinly slice the green tops lengthwise, then soak in a bowl of ice water for 8-10 minutes.
