Ingredients

  • Four 8-ounce salt cod fillets, or 1 whole side bone-in salt cod (about 3 1/2 pounds)
  • One 14-ounce can peeled Italian plum tomatoes (preferably San Marzano)
  • 1/2 cup extra-virgin olive oil, plus additional oil for the finished dish if you like
  • 3 cloves garlic, peeled
  • 8 large green olives, such as Cerignola, cut away from the pit in wide strips
  • 1 tablespoon chopped fresh oregano
  • Freshly ground black pepper
  • Salt

Method

  • With your hands, remove the seeds from the tomatoes by squeezing them over a sieve, squeezing just enough to get the seeds out, then crush the tomatoes that you have in your hands coarsely and return them to the seedless liquid.
  • Heat 1/4 cup of the olive oil in a large, heavy skillet over medium-high heat.
  • Whack the garlic with the flat side of a knife, scatter the cloves over the oil, and cook, shaking the pan, until lightly browned, about 2 minutes.
  • Stir in the olives and cook until any liquid has evaporated and the olives begin to sizzle, about 1 minute.
  • Add the tomatoes and oregano and bring to a boil.
  • Lower the heat so the sauce is at a lively simmer and season lightly with pepper.
  • Let simmer while you prepare the cod, spooning in a little hot water if the sauce begins to thicken.
  • Pat the salt-cod fillets dry with paper towels.
  • Heat the remaining 1/4 cup oil in a separate large skillet over medium heat.
  • Add the fillets and cook, turning once, until lightly browned on both sides and opaque at the thickest point, about 10 minutes.
  • Drain excess oil from the skillet and carefully pour in the tomato sauce.
  • Bring to a quick boil, lower the heat so the sauce is simmering, and simmer 2 to 3 minutes, basting the fish with the sauce as it cooks.
  • Taste the sauce and add salt and pepper, if necessary.
  • Divide the sauce among four heated plates and top each pool of sauce with the fillets.
  • Drizzle each fillet with additional olive oil, if you like.
