A cup of asparagus potato soup on the table with little dish of tips and a spoon to the side.

Asparagus Potato Soup

This asparagus potato soup comes together in one pot in about 35 minutes and gets its silky, creamy texture entirely from blended potatoes without any cream needed. Sauteed leeks, a touch of tarragon, and a bright squeeze of lemon at the end make it taste like spring in a bowl. This soup is perfect for a light lunch, a simple weeknight dinner, or making ahead for the week.

Recipe Tips

 
  • Don't overcook the asparagus. All it needs is 3–5 minutes to turn out tender and stay bright green. 
  • Taste and season after blending. The flavor shifts once the soup is blended, and it almost always needs a little more lemon or salt at the end. 
  • If your soup turns out stringy. Strain through a fine mesh sieve after blending to remove the strings. 
  • For a chunkier soup. Blend only half and stir it back into the rest for a more rustic, textured result.
