Why It Works

  • A base of aromatic vegetables like onion, leek, garlic, and celery provides the foundation for the parsnips' natural sweetness.
  • Complementary and contrasting aromatics, like citrusy coriander seeds, spicy jalapeño, and fresh-yet-warm ginger, add just enough dimension to make things interesting.

Parsnips are possibly my favorite root vegetable. Their sweet, earthy flavor is just irresistible. But like most things—even great, delicious things—they can be a little one-dimensional on their own. That's especially true in a soup, where boiling and simmering don't necessarily offer the same level of flavor transformation as, say, roasting. (Of course, you can roast your main soup ingredient first, but then you lose some of its pure, clean flavor.)

The key to overcoming that is to layer complementary and contrasting flavors. Like most creamy vegetable soups, I start with a basic method of sautéing aromatics in butter or oil. For this soup, I used a combination of onion, leek, celery, and garlic. If I had left it at that, I'd have ended up with a very simple, but possibly boring soup.

Instead, I added a few other aromatic ingredients for interest: coriander seed, a spice that I can not get enough of, is fragrant in a kind of woodsy, citrusy way; jalapeño, meanwhile, adds just enough heat to warm the mouth, and fresh ginger backs that heat up with its own particular combination of bright and warming spice.

Then I add the parsnips and just enough chicken stock to cover (though you can make this vegetarian with vegetable stock or even water), and let it simmer until everything is tender. The blender turns the soup creamy, despite its lack of dairy, but I take the extra step of pressing it through a fine mesh strainer with the help of a ladle to get an even silkier texture. (If I owned a high-power blender, which I sadly don't, I could get an even better texture without straining it at all.)

It comes out a little too thick, so the last step is to thin the soup to the desired consistency with water or more stock, if you have it.

I garnished the soup with whipped cream that I'd lightly seasoned with allspice and a dash of cayenne for color, but if you'd rather not introduce dairy, you could garnish with so many other things, like glazed chestnuts, sautéed mushrooms, or a lemony gremolata.

Ingredients

  • 1/4 cup extra-virgin olive oil

  • 2 teaspoons whole coriander seeds

  • 3 medium yellow onions, diced (about 3 cups)

  • 2 stalks celery, diced (about 2/3 cup)

  • 1 leek, white and light green parts only, diced (about 1/2 cup)

  • 6 medium cloves garlic, smashed

  • 1 jalapeño pepper, stemmed and roughly chopped

  • 1 (2-inch) piece fresh ginger, peeled sliced

  • 3 pounds parsnips, peeled and roughly chopped

  • 1 quart homemade or store-bought low-sodium chicken stock or vegetable stock

  • Water, as needed

  • Kosher salt and freshly ground black pepper

  • Fresh lemon juice, to taste

  • Whipped cream lightly flavored with ground allspice, for garnish

  • Cayenne pepper, for garnish

Directions

  1. In a Dutch oven, heat oil over medium-high heat until shimmering. Add coriander seeds and cook until fragrant, about 30 seconds. Add onion, celery, leek, garlic, jalapeño, and ginger, and cook, stirring occasionally, until softened, about 10 minutes.

  2. Add parsnips and stock and bring to a boil. Lower heat and simmer until parsnips are tender, about 20 minutes. Using a blender or immersion blender, purée soup until smooth (it will be thick at this point). Season with salt and pepper. For an extra-silky texture, press soup into a bowl through a fine-mesh strainer. Thin soup to desired consistency with water or additional stock and season once more with salt and pepper. Add lemon juice 1 teaspoon at a time to taste.

  3. Wipe out Dutch oven and return soup to Dutch oven. Reheat over medium heat, stirring, until hot. Serve, spooning dollops of spiced whipped cream and a sprinkle of cayenne on each bowl.
