  • Step 1

    Preheat a ridged stovetop grill pan or outdoor grill. Season tuna with salt and pepper. Brush grill pan or grill with oil. Grill tuna until well browned but still rare, about 2 minutes per side; the flesh will be firm and tight. For medium rare, cook 1 minute more, until the flesh begins to pull apart. For medium, cook 2 minutes more, until the flesh flakes apart.

    Meanwhile, in a small saucepan, combine lemon zest and juice, anchovies, oil, and garlic. Bring to boil over medium heat, remove from heat, and stir in oregano and basil. Serve immediately with sauce spooned over tuna.

The grill offers you two ways of preparing tuna. One method is to grill a thinner tuna steak over high heat until it is cooked through. The other method is to quickly grill it over very high heat, searing the outside, which leaves the fish mostly raw, but seared tuna is an Asian favorite that's becoming more and more commonplace in the U.S.

The Basics of Grilling Tuna

No matter how you prepare tuna, always shop at a reputable market with only the highest quality seafood available. Look for tuna with deep red, even color without dark patches. Tuna is great for grilling and is uniquely meaty and delicious. Luckily, it is also easy to cook.

Tuna is a very lean fish and tends to dry out quickly on the grill. While serving with sauce will help, if you cook tuna beyond medium rare it is most likely be dry. To help combat dryness, you can marinate the tuna. Anything with a lot of acid will begin to cook the fish before it hits a heat source (similar to the way ceviche cures fish in acidic citrus juices), so the marinade should be pretty mild and the tuna should not marinate for very long. Use a drizzle of high-quality olive oil, herbs, spices, and a small amount of lemon juice or flavored vinegar and marinate for just a few minutes while the grill heats.

Fully Cooked Grilled Tuna

If you choose a piece of tuna that is about 1-inch-thick, it will grill in about 8 to 10 minutes, provided that your grill is very hot. Remove tuna from the grill before the surface starts to get crusty and burns. Unlike beef, lamb, or pork, you do not need to let tuna rest before serving. Get it off the grill and onto the plate right away.

Seared Grilled Tuna

For seared tuna, purchase a piece of tuna that is about three inches thick. Prepare it simply with a light brushing of oil and a generous sprinkling of salt and pepper. Preheat the grill until it is very hot. The major difference between grilling and searing tuna is the level of heat. Some gas grills simply can not produce the intensity of heat necessary to properly sear a piece of tuna. In this case, use a heavy cast-iron skillet. The iron skillet will absorb and hold the heat, giving you a good sear as long as you preheat the pan. If you trust your grill to produce the level of heat needed, then go straight to the grate; otherwise, use the skillet or a heavy-duty griddle.

Charcoal grills will allow you to bank up hot coals under the grate to get the kind of intense heat you need. The tuna sears for less than one minute per side, leaving the interior raw. Sear your thick cut of tuna on all four or six sides for about 45 seconds per side. The result is a piece of tuna that has a fantastic seared crust all around and a heated but raw middle. 

How to Serve Grilled Tuna

If you've cooked your tuna through and it's a little dry, or you just want to add more flavor, serve it with a sauce or a salsa. Pineapple ango salsa, ginger and lime sauce, or buttery lemon chive sauce all compliment grilled tuna nicely.

Thinly slice seared tuna the way you would a steak and serve it immediately with a spicy wasabi sauce or a balsamic reduction. Tuna can be served with grilled vegetables, rice, or as part of a Niçoise salad bowl.

Let's get grilling

1

Remove the tuna steaks from the refrigerator and allow them to rest as you prep the grill. They should be out of the refrigerator 20 minutes before cooking.

2

Build a Kingsford® Charcoal fire on the grill, and open all dampers for maximum heat. Apply a light coat of oil to the hot grill grates, and heat the grill to approximately 500–600°F.

3

Remove the tuna steaks from the plastic wrap and lightly coat with oil. Season to taste with salt and pepper and place them onto the grill, directly over the heat.

4

Grill for 3 minutes on each side or less depending on your preference. Tuna should be firm with pink in the middle. If you prefer your grilled tuna steak rare to medium-rare, reduce grilling time to 1½ to 2 minutes per side.

5

You can serve grilled tuna steaks whole or slice them into ¼ inch strips.

How do you know when tuna is done on the grill?

Pat the tuna dry and sprinkle liberally with salt and pepper. Grill 30 to 60 seconds per side, until cooked on the outside but still raw on the inside. It's helpful to use a food thermometer: the internal temperature should be 115 degrees Fahrenheit.

How long should tuna steaks be cooked?

Cook, uncovered, 4 to 6 minutes per ½-inch thickness (6 to 9 minutes for the ¾-inch-thick steaks we suggest) or until fish begins to flake when tested with a fork but is still pink in the center, turning once during cooking. Adjust the heat as needed if the skillet gets too hot.

Do you flip tuna on the grill?

Sear and Cook the Tuna Place the tuna steaks over the hottest part of the grill. Leave that side down for 1-2 minutes until browned and crispy. Then, flip to the other side and sear for another 1-2 minutes. Now, you can pull it off the grill or continue to cook it to your desired doneness level.

How long does it take to grill ahi tuna steaks?

Grill Your Ahi Tuna Steaks Place your thawed and seasoned ahi tuna steaks directly on the grill grates. If you prefer a medium-rare doneness cook the tuna steaks for 60-90 seconds on each side, or until seared. For a medium doneness, cook each tuna steak 4-5 minutes on each side or until opaque throughout.
