Ingredients

  • 1/4 cup capers, drained
  • 2 tablespoons chopped oregano
  • 1 small shallot, minced
  • 1 1/2 tablespoons extra-virgin olive oil, plus more for drizzling
  • Salt and freshly ground pepper
  • Four 6-ounce, 3/4-inch-thick tuna steaks
  • 4 anchovy fillets, chopped
  • 1 cup dry red wine
  • 2 tablespoons cold unsalted butter, cut into 2 pieces
  • 4 cups packed baby arugula

Method

  • In a bowl, mix the capers with the oregano, shallot and 1/2 tablespoon of the olive oil.
  • Season with salt and pepper.
  • In a skillet, heat the remaining 1 tablespoon of oil until shimmering.
  • Season the steaks with salt and pepper; add to the skillet and cook over high heat, turning once, until browned and medium-rare, about 4 minutes.
  • Transfer the steaks to a platter.
  • Add the anchovies to the skillet and cook over moderate heat, mashing with a fork until dissolved, about 1 minute.
  • Add the wine and boil until reduced by half, about 4 minutes.
  • Remove the skillet from the heat and swirl in the butter, 1 piece at a time, until blended and smooth.
  • Season the red wine sauce with salt and pepper.
  • In a medium bowl, drizzle the arugula with olive oil and season with salt.
  • Mound the arugula alongside the tuna.
  • Pour the red wine sauce around the tuna steaks, top them with the caper mixture and serve.
