Make this silky smooth, flavorful asparagus soup by roasting the asparagus first for deep taste. This recipe uses Greek yogurt for creaminess, keeping it lighter than traditional cream-based soups.

Ingredients

Scale
  • 1 pound fresh asparagus, tough ends snapped off
  • 1 tablespoon olive oil
  • 1 large leek, white and light green parts only, sliced
  • 2 cloves garlic, minced
  • 4 cups vegetable broth
  • 1/2 cup plain Greek yogurt (or cashew cream for dairy-free)
  • 1 teaspoon lemon zest
  • 1 tablespoon fresh lemon juice
  • Salt and black pepper to taste
  • Optional: Asparagus tips for garnish

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius). Toss the trimmed asparagus spears with olive oil, salt, and pepper on a baking sheet. Roast for 10 to 12 minutes until tender and slightly browned. Set aside about 1/4 cup of the tips for garnish, if using.
  2. In a large pot or Dutch oven, sauté the sliced leek over medium heat until soft, about 5 minutes. Add the minced garlic and cook for 1 minute more until fragrant.
  3. Add the roasted asparagus (reserving the tips) and the vegetable broth to the pot. Bring the mixture to a simmer and cook for 5 minutes to allow flavors to combine.
  4. Remove the pot from the heat. Carefully transfer the soup mixture to a blender, or use an immersion blender directly in the pot. Blend until completely smooth and velvety.
  5. Return the soup to low heat. Stir in the Greek yogurt, lemon zest, and lemon juice. Heat gently until warmed through; do not boil after adding the yogurt.
  6. Taste and adjust seasoning with salt and pepper. Serve immediately, garnished with the reserved asparagus tips.

Notes

  • For a richer flavor, roast the asparagus longer until it is deeply caramelized.
  • If you prefer a thinner soup, add more vegetable broth until you reach your desired consistency.
  • This soup tastes excellent made ahead and reheated gently the next day.
