Ingredients


For squash soup

  • 3/4 stick unsalted butter, cut into pieces
  • 1 medium onion, halved lengthwise and thinly sliced crosswise
  • 1/2 tsp salt
  • 2 lb yellow summer squash, halved and thinly sliced
  • 2 carrots, thinly sliced
  • 1 yellow-fleshed potato (1/2 lb), peeled, halved
  • 4 cups chicken stock or reduced-sodium chicken broth


For pistou

  • 3/4 cup loosely packed fresh mint leaves
  • 1/2 cup loosely packed fresh flat-leaf parsley sprigs
  • 1 large scallion, chopped (1/2 cup)
  • 1/4 cup extra-virgin olive oil
  • 2 tbsp water
  • 1/4 tsp salt

Directions

  • Melt butter in a 6- to 8-quart wide heavy pot over moderate heat, then cook onion with salt, stirring, until softened, about 8 minutes.
  • Add squash, carrots, potato, and stock and bring to a boil.
  • Reduce heat, then simmer, partially covered, until vegetables are very tender, about 20 minutes.
  • Remove from heat and cool soup, uncovered, 10 minutes.
  • Working in batches, purée soup in a blender until smooth (use caution when blending hot liquids) and transfer to a bowl.
  • Return purée to cleaned pot and thin with water if desired; simmer 3 minutes. Season with salt.
  • Pulse mint, parsley, and scallion in a food processor until finely chopped. With motor running, add oil in a stream, then add water and salt, blending until incorporated.
  • Swirl 1 tablespoon pistou into each bowl of soup.

  • Soup (without pistou) can be made 2 days ahead and cooled, uncovered, then chilled, covered. Reheat before serving, thinning with additional water if desired.
  • Pistou keeps, its surface covered with plastic wrap, chilled, 3 days. Bring to room temperature before using.
