Confession: I’m not that big on soup. I don’t consider it a complete meal by itself, so when I do make soup, it’s usually eaten alongside a sandwich or salad. But when I’m short on time and need to throw something together, soup is a good option. For this reason, I try to minimize the amount of knife work required and either make a chunky soup (like the Beet Green and Chickpea Soup) or a pureed soup like this one. If you have guests with dietary restrictions, keep this recipe in your back pocket—it’s vegan and gluten-free.
Parsnip Soup
In a medium saucepan, heat the oil over medium heat. Add the onion, garlic, and 1 tablespoon salt and cook, stirring, until softened, about 5 minutes. Add the parsnips and cook, stirring occasionally, until the outsides of the parsnips are slightly softened, about 10 minutes. Add the water and bring to a boil. Reduce the heat to medium and simmer until the parsnips are very tender, about 30 minutes. Let cool slightly, then transfer the soup to a blender (or use an immersion blender) and puree until smooth, working in batches if necessary. Keep warm.
Sautéed Mushrooms
While the soup is cooking, heat the olive oil in a medium skillet over high heat. Add the mushrooms and ½ teaspoon salt. Cook the mushrooms, stirring occasionally, until deeply caramelized, about 5 minutes. Scrape the mushrooms into a bowl and add the lemon zest and juice, the chile, parsley, and scallion. Toss to combine. Season to taste with salt and pepper.
For Serving
Ladle the soup into bowls and top with the mushrooms. Drizzle with olive oil, sprinkle with flaky salt and a few grinds of pepper, and serve.
The Takeaway
As with the beet green soup, I like pairing simple, rustic soups with more dramatic garnishes. Instead of bread and cheese here, I reach for a mixture of mushrooms, which I sauté until they’re both crispy and chewy, adding lots of texture and savory flavors to an otherwise simple soup.
