A quick and easy creamy asparagus soup with a bright lemon crème fraîche topping that balances earthiness with fresh, tangy creaminess. Perfect for any season and simple to prepare.

Ingredients

Scale
  • 1 pound fresh asparagus, trimmed and chopped (tender spears, not woody stalks)
  • 2 tablespoons unsalted butter
  • 1 medium yellow onion, finely chopped
  • 2 cloves garlic, minced
  • 1 medium potato, peeled and diced
  • 4 cups vegetable broth (preferably low sodium)
  • Zest and juice of 1 medium lemon
  • ½ cup crème fraîche, chilled (or sour cream/Greek yogurt as substitute)
  • Salt and freshly ground black pepper, to taste
  • 1 tablespoon olive oil (for finishing or roasting asparagus tips)

Instructions

  1. Rinse and trim the asparagus, chopping stalks into 1-inch pieces. Set aside the tender tips separately for roasting or garnish later.
  2. Dice the potato, chop the onion, and mince the garlic.
  3. In a large pot, melt 2 tablespoons of unsalted butter over medium heat.
  4. Add the chopped onion and cook until translucent and soft, about 5 minutes.
  5. Stir in the minced garlic and cook for another minute until fragrant but not browned.
  6. Add the diced potato and asparagus stalk pieces (not the tips). Stir to coat with butter and aromatics and cook for 3-4 minutes.
  7. Pour in 4 cups of vegetable broth, bring to a boil, then reduce heat and simmer gently for 15-20 minutes until potatoes and asparagus are tender.
  8. Remove the pot from heat and blend the soup until smooth and creamy using an immersion blender or regular blender in batches. Season with salt and black pepper to taste.
  9. Optional: Toss reserved asparagus tips with olive oil, salt, and pepper. Roast in a 400°F oven for 8-10 minutes until tender and lightly caramelized.
  10. In a small bowl, gently fold crème fraîche with lemon zest and 1 teaspoon fresh lemon juice. Adjust to taste.
  11. Ladle soup into bowls, add a dollop of lemon crème fraîche on top, and garnish with roasted asparagus tips or fresh herbs if desired.

Notes

When blending hot soup, start on low speed and hold the lid tightly to avoid splashes. Potato adds creaminess without heavy cream. If soup is too thick, add more broth or water. Separate asparagus tips for roasting to keep texture and color. Lemon crème fraîche should be folded gently to keep it light and airy. For vegan version, substitute butter with olive oil and crème fraîche with coconut cream or plant-based yogurt.
