Ingredients

  • 1 teaspoon kosher salt
  • 6 tuna steaks, about 6 to 8 ounces each, cut 1 inch or thicker
  • 1/2 cup or so all-purpose flour, spread in a plate for dredging
  • 1/3 cup extra-virgin olive oil, plus more as needed
  • 1/2 ounce dried porcini (about 1/2 cup loosely packed pieces), soaked in 1 cup warm water
  • 6 plump garlic cloves, crushed and peeled
  • 2 small anchovy fillets, drained and finely chopped (about 1 teaspoon)
  • 1 1/2 cups dry white wine
  • 2 tablespoons freshly squeezed lemon juice
  • 3 sprigs fresh thyme
  • 2 tablespoons butter (or extra-virgin olive oil)
  • 2 tablespoons chopped fresh parsley
  • A heavy-bottomed skillet or saute pan, 12-inch diameter or larger

Method

  • Sprinkle salt all over the tuna steaks, using about 1/2 teaspoon salt in all.
  • Dredge each steak in the flour, coating both sides, and shake off the excess.
  • Pour 4 tablespoons of the olive oil into the skillet, and set it over medium-high heat.
  • When the oil is hot, lay all the tuna in the pan, and saute on the first side for about 1 minute, just until browned.
  • Flip the steaks over, and brown the second side, another minute or so, then take the pan off the heat.
  • Transfer the tuna to a platter, and keep in a warm place while you make the sauce.
  • Lift the rehydrated porcini pieces from the soaking water (reserve it), and chop them fine.
  • Pour the remaining 2 tablespoons olive oil into the skillet, set it over medium-high heat, toss in the garlic cloves, then stir in the chopped anchovy and porcini.
  • Cook and stir until everything is sizzling nicely, then pour in the white wine, lemon juice, and porcini water (leaving behind any sediment).
  • Add the thyme sprigs, and season with the remaining salt.
  • Bring the sauce to a boil, and cook until reduced by about half.
  • When the sauce has thickened to a consistency you like, arrange the tuna steaks in the skillet again, and pour in any juices from the platter.
  • Heat for a minute in the bubbling sauce, then turn the steaks over and cook briefly on the second side.
  • The tuna should still be rare at this point; if you prefer your steaks better done, simply let them cook in the sauce longer.
  • Just before serving, drop the 2 tablespoons butter (or extra-virgin olive oil, if you prefer) into the pan, between the steaks, and stir it into the sauce as a final enrichment.
  • Turn off the heat, and stir in the parsley.
  • Serve the steaks on dinner plates, spooning sauce over them, or arrange them on a serving platter, with the sauce on top.
