Tastes Like Spring Soup

April 27, 2011

Author Notes:

With beautiful asparagus at the farmer’s market and fresh leek and fennel in my CSA box, I could not resist making a spring soup. Topped with a slightly peppery nasturtium bloom and a drizzle of earthy truffle oil, this soup reminds me of all the reasons I am happy it is spring.


Makes: 1 quart


  • 1 1/4 pounds asparagus, woody ends broken off
  • 1 baby fennel bulb, trimmed, thinly sliced crosswise (2 oz when trimmed)
  • 2 baby leeks, trimmed, washed, thinly sliced (2 oz when trimmed)
  • 1 tablespoon olive oil
  • 2 tablespoons unsalted butter
  • 1/4 cup vermouth (can substitute 3 T vodka)
  • 1 1/4 cups water
  • 1/2 cup half and half
  • 1-2 tablespoons mascarpone
  • Squeeze of a small Meyer lemon wedge
  • Sea salt to taste, if desired
  • Nasturtium blooms (optional, but recommended)
  • Truffle oil (optional, but recommended)
In This Recipe


  1. Trim off asparagus tips (about top 2 inches) and set aside. Slice remaining stems on the bias, in one inch pieces and place in a bowl.
  2. Heat olive oil and butter over medium heat in a Dutch oven. When foam subsides, add sliced leeks and fennel and cook, stirring, beginning to get soft and translucent. Add sliced asparagus and vermouth (or vodka), stir and cook for 30 seconds. Cover pot and cook for 3 minutes. Add reserved tips, cover and cook for 3 minutes more. Remove from heat.
  3. Add water and half-and-half to pot. Carefully transfer mixture to a blender. Puree mixture until smooth. Add mascarpone, starting with one tablespoon, and white wine vinegar and puree again. Taste to adjust seasonings adding an additional tablespoon of mascarpone if desired. Add squeeze of lemon, and sea salt if desired.
  4. Serve in bowls at warm, at room temperature or chilled. Top with nasturtium bloom and a drizzle of truffle oil if desired. Enjoy!

Thanks so much TiggyBee!! I actually made it again tonight and tried it without roasting the fennel - I think in this application it works better, since the roasted fennel flavor was almost overpowering the asparagus.

Gorgeous! I just planted some nasturtiums a few days ago, so I've got a while to wait for the flowers.

Thank you, hardlikearmour! I had never eaten a nasturtium before growing one. They have a lovely light peppery bite to them that I really enjoy. Have you ever pickled their seeds?
