  • 4 tuna steaks ,about 6 ounces each and 1 inch thick (swordfish makes a great substitute)
  • Extra virgin olive oil for brushing
  • Kosher salt and freshly ground black pepper
  • 1 tablespoon extra virgin olive oil
  • 2 cloves garlic minced
  • 1 cup diced fresh tomatoes
  • 1 cup dry white wine
  • 2/3 cup sliced firm green olives (I used Lindsay Sicilian-style Olives)
  • 1/4 cup capers ,drained (I used Lindsay)
  • 1 1/2 tablespoons fresh lemon zest
  • 2 tablespoons fresh lemon juice
  • 2 teaspoons chopped fresh thyme
  • 2 teaspoons chopped fresh parsley
  • 1/4 teaspoon salt
  • 1/4 teaspoon freshly ground black pepper
  • 1/4 cup chopped fresh parsley


  • Brush the tuna with some oil and sprinkle with salt and pepper. Heat the grill and brush the cooking grates with oil.
  • Heat the oil in a small skillet over medium heat and cook the garlic for a minute. Add the tomatoes and cook for another couple of minutes. Add the wine and bring to a rapid boil for two minutes. Add all remaining ingredients except for the parsley and simmer uncovered for 5 minutes. Stir in the parsley and remove from heat.
  • Sear the tuna steaks over high, direct heat for 1-2 minutes on each side. (For the best texture and to prevent becoming dried out tuna should be rare to medium rare on the inside.)
  • Serve the tuna steaks immediately topped with the sauce.
