Cauliflower Soup with Parmesan Croutons

Author: Canadian Living

This recipe makes delicious and thrifty use of the 1/4-inch (5 mm) thick rinds that remain after grating wedges of Parmigiano-Reggiano. They infuse this velvety soup with a rich salty bite.

  • 2 tablespoons butter
  • 1 onion chopped
  • 1 onion (white and light green parts only) chopped
  • 1 leek (white and light green parts only) chopped
  • 1 celery stalk chopped
  • 1 clove garlic minced
  • 1/2 teaspoon salt
  • 1 pinch ground nutmeg
  • 1 pinch cayenne pepper
  • 6 cups cauliflower florets (about 1 head)
  • 1 potato peeled and chopped
  • 3 cups vegetable stock
  • 1 1/2 cup milk
  • 1/4 cup dry sherry
  • 1/4 cup vegetable stock
  • 2 rinds (each 4 x 2 inch/10 x 5 cm) Parmigiano Reggiano cheese
  • 2 rinds (each 4 x 2 inch/10 x 5 cm) Parmesan cheese
Parmesan Croutons:
  • 2 cups cubed (1/4 inch/5 mm) day-old bread
  • 1/3 cup grated Parmigiano Reggiano cheese
  • 1/3 cup grated Parmesan cheese
  • 2 tablespoons extra-virgin olive oil
  • 1/4 teaspoon crumbled dried thyme
  • 1 pinch salt
  • 1 pinch cayenne pepper


Parmesan Croutons: In bowl, toss together bread, cheese, oil, thyme, salt and cayenne; spread on rimmed baking sheet. Bake in 350°F (180°C) oven until golden and crisp, about 10 minutes. Let cool. (Make-ahead: Store in airtight container for up to 5 days.)

In large saucepan, melt butter over medium heat; fry onion, leek, celery, garlic, salt, nutmeg and cayenne, stirring often, until softened, about 8 minutes.

Stir in cauliflower, potato, stock, milk, sherry and cheese rinds; bring to boil. Reduce heat, cover and simmer until vegetables are tender, stirring occasionally, about 30 minutes. Let cool slightly. With tongs, remove cheese rinds, scraping any gooey cheese back into soup. Discard rinds.

In batches, puree soup in blender until smooth. (Make-ahead: Let cool for 30 minutes. Refrigerate, uncovered, in airtight container until cold. Cover and refrigerate for up to 2 days.)

Return to clean saucepan; heat through over medium heat, stirring occasionally. Ladle into bowls; sprinkle with Parmesan Croutons.
