Instead of burying the flavor of asparagus under a blanket of cream, this delicate soup is subtly enriched with a less-expected ingredient: Greek yogurt. This simple swap is less about lightening things up and more about bringing asparagus's green, vegetal quality to the fore. (Its modest calorie count is a happy coincidence.)
Delicate in texture, it's the perfect start to a Spring meal. (Or round it out with a piece of buttered toast for a light lunch or dinner.) Divvied up into small glasses, it also makes for a shockingly low-fuss hors d'oeuvre for a cocktail party or formal dinner party: make it ahead, reheat, and pour; that's it.
Gently reheat leftovers (don't let them come to a boil) as the yogurt can curdle if overheated. To make this soup vegan, omit the Greek yogurt, and instead add acidity with 1/2 teaspoon lemon zest plus the juice of 1/2 a lemon.
1/4 cup extra-virgin olive oil, plus more for drizzling
1 large shallot, thinly sliced
Pinch of crushed red pepper flakes
1 pound asparagus, trimmed, chopped
4 cups vegetable stock, preferably homemade
1 cup loosely packed spinach leaves
1/2 cup full-fat Greek yogurt
- In a medium saucepan, heat 2 tablespoons oil over medium-high heat. Add shallot, red pepper flakes, and a pinch of salt. Cook, stirring occasionally, until shallots are tender and just beginning to brown, about 5 minutes. Add chopped asparagus, and cook for 1 minute. Stir in broth and bring to a boil. Reduce heat to a simmer; continue cooking until asparagus is tender, about 15 minutes. Remove from heat; add spinach.
- Carefully transfer to a blender, add remaining 2 tablespoons oil and Greek yogurt, and blend until smooth. Season to taste with salt (1 teaspoon kosher salt was just right for us).
- Ladle soup into bowls, drizzle with olive oil, and serve.
