Ingredients

  • 2 pounds Swiss chard
  • 1 onion, chopped (about 1 cup)
  • 2 celery stalks, trimmed, peeled, and cut into chunks (about 1 1/2 cups)
  • 1/3 cup fresh Italian parsley leaves
  • 8 fresh basil leaves
  • 1/3 cup extra-virgin olive oil
  • 1/2 teaspoon peperoncino flakes, or to taste
  • 1 tablespoon tomato paste
  • 9 cups water
  • 2 teaspoons salt, or to taste
  • 1/4 teaspoon freshly ground black pepper, or to taste
  • 1 egg
  • 1/2 slice day-old country bread, or 3 or 4 large croutons
  • Freshly grated pecorino to taste
  • A food processor
  • A heavy-bottomed saucepan or soup pot, 5-or 6-quart capacity, with a cover
  • A skillet or saute pan, 3-inch sides or deeper, with a cover, for poaching eggs

Method

  • Wash and drain the chard, and tear out the long stems from the leafy parts.
  • Stack the leaves, and slice crosswise into 1-inch strips.
  • Cut off the tough base of each stem, and discard.
  • Chop the trimmed stems into 1/2-inch pieces.
  • Using a food processor, mince the onion, celery, parsley, and basil into a fine-textured paste (pestata).
  • Heat the oil in the saucepan over medium heat, scrape in the pestata, and stir it all around the pan as it starts to steam and sizzle.
  • Sprinkle in the peperoncino and cook, stirring, until the pestata has dried and starts to stick, 4 minutes or so.
  • Drop in the tomato paste, and stir to toast it for a minute.
  • Pour in 9 cups water, raise the heat to high, and stir up all the cooked seasonings, while adding 2 teaspoons of salt and some freshly ground pepper to taste.
  • Bring the water to the boil, and dump in all of the cut chard leaves and chopped stems.
  • Return to the boil, cover partially, and cook at a steady simmer for about 40 minutes, until the chard is very tender and the broth is quite flavorful.
  • Turn off the heat until youre ready to serve.
  • Ladle about 1 1/3 cups of soup per serving into the skillet.
  • Heat to a simmer; crack and carefully slip into the soup one egg for each serving.
  • Turn the heat down very low, cover the skillet tightly, and poach the eggs for 2 minutes or longer.
  • Put a bread slice or croutons in each warm soup bowl, and when the eggs are done as you like them, lift them out one at a time with a slotted spoon or spatula, taking some cooked greens too.
  • Lay the egg and greens on the bread, and ladle in hot broth to cover.
  • Sprinkle pecorino over the egg and broth, and serve immediately, passing more cheese at the table.
