Roasted Asparagus Soup

Creamy, yet fresh and light, this soup takes full advantage of the abundance of springtime asparagus.  Roasting the asparagus brings out its sweetness and gives the soup a subtle smoky note while a touch of cream adds richness.   An immersion blender is a great tool for blending vegetable soups.  If you don’t have one, a traditional blender or food processor will get the job done.

Cooking Directions

  • Heat the oven to 425°F.  Place the asparagus on a rimmed baking sheet and drizzle with 1 tablespoon oil.
  • Roast the asparagus for 10 minutes or until tender.  Let cool.  Cut into 1-inch pieces.
  • While the asparagus is roasting, heat the remaining oil in a 4-quart saucepot over medium heat.  Add the onion and garlic and cook for 5 minutes or until the onion is tender, stirring occasionally.
  • Reduce the heat to low. Add the flour to the onion mixture. Cook for 5 minutes, stirring often. Gradually stir in the broth. Heat to a boil.  Cover and cook for 10 minutes.
  • Add the asparagus to the saucepan.  Using an immersion blender, blend until the mixture is smooth.  Add the heavy cream and blend until combined.  Season to taste.
