Ingredients

Makes 4 servings

　　6 tablespoons extra-virgin olive oil

　　4 (5- to 6-ounce) tuna steaks

　　Salt and freshly ground black pepper

　　1 large onion, sliced (about 1 cup)

　　2 garlic cloves, minced

　　3 tablespoons salted capers, soaked in water for 10 minutes and drained

　　3 tablespoons minced pitted green olives

　　1/4 cup raisins

　　5 plum tomatoes, peeled, seeded, and chopped

　　1 cup fish stock or water, as needed

　　2 tablespoons fresh flat-leaf parsley, coarsely chopped

　　4 to 5 fresh basil leaves, torn

　　1/3 cup pine nuts, toasted

　　

Step 1

1. In a medium skillet over moderately high heat, warm the oil. Season the tuna with salt and pepper and sauté, turning once, until golden on both sides, 3 to 4 minutes total. Remove the tuna and set aside. Do not clean the pan.

　　

Step 2

2. In the same pan over low heat, sauté the onion, stirring frequently, until just tender, about 1 minute. Add the garlic, capers, olives, raisins, and tomatoes, and continue cooking, stirring, until heated through, about 2 minutes. If the tomatoes don't release much juice, add the fish stock or water to give the sauce some body.

　　

Step 3

3. Return the tuna to the pan and cover it with a tight-fitting lid. Cook over moderate heat until the tuna reaches the desired doneness, 2 to 3 minutes for medium.

　　

Step 4

4. Add the parsley and basil and stir to incorporate, then season to taste with salt and pepper. Serve the fish with the sauce spooned over the top; garnish with pine nuts.
