Ingredients

Scale
  • 2 pounds fresh asparagus, woody ends trimmed
  • 3 tablespoons unsalted butter
  • 1 medium yellow onion, chopped
  • 3 cloves garlic, minced
  • 4 cups low-sodium vegetable or chicken broth
  • 1 medium russet potato, peeled and diced
  • 1 cup heavy cream or half-and-half
  • 1 cup freshly grated Parmesan cheese, plus more for serving
  • 1 teaspoon kosher salt, plus more to taste
  • ½ teaspoon freshly ground black pepper
  • Pinch of red pepper flakes (optional)
  • Fresh herbs for garnish: chives, dill, or parsley

Instructions

  1. Prep the asparagus by cutting the spears into 1-inch pieces, reserving a handful of tender tips for garnish.
  2. In a large pot, melt butter over medium heat. Add onion and cook until soft, about 5-7 minutes. Add garlic and cook for 30 seconds until fragrant.
  3. Add the chopped asparagus (except reserved tips), diced potato, broth, salt, pepper, and red pepper flakes. Bring to a boil, then reduce to a simmer. Cover and cook for 15-20 minutes until vegetables are tender.
  4. While soup simmers, blanch reserved asparagus tips in boiling salted water for 1-2 minutes. Drain and set aside.
  5. Carefully puree the hot soup using an immersion blender or a countertop blender until completely smooth.
  6. Return soup to low heat. Stir in heavy cream and grated Parmesan until cheese is melted and soup is heated through. Adjust seasoning.
  7. Ladle soup into bowls. Top with blanched asparagus tips, extra Parmesan, black pepper, and fresh herbs.

Notes

For a smoother blend with a countertop blender, remove the center lid plug and cover with a towel to let steam escape. Use freshly grated Parmesan, as pre-grated can make the soup grainy. Soup can be made ahead and stored for up to 4 days.
