Grilled tuna steak recipes aren't limited to restaurants. After enjoying yellowfin tuna in southwest Florida, I came up with this recipe so I could enjoy the flavor of my favorite fish at home. —Jan Huntington, Painesville, Ohio

Grilled Tuna Steak Tips

Should tuna steak be pink in the middle?

Tuna steaks can be pink in the middle because it keeps it moist, tender and flavorful. If cooked longer, tuna steaks can dry out quickly. You can tell a tuna steak is done when the outside is firm to the touch, it can be easily flaked with a fork and the center is still pink. Better yet, use a meat thermometer and aim for an internal temperature of 90°F (32°C).

What is a good side dish for tuna steaks?

Tuna steaks lend themselves beautifully to a number of delicious sides. Serve them with a simple salad like mixed greens with lemon champagne vinaigrette and warm green bean and potato salad. You can also pair tuna steaks with almond vegetable stir-fry or lemon rice pilaf.
