How to make Grilled Tuna Steak

This grilled tuna dinner is simple to prepare, with easy to find ingredients the whole family will love.

Marinated Tuna Steak Ingredients

Grilling tuna steaks is simple – but starts with high quality ingredients.

To make this recipe, you'll need:

• Tuna steaks – ask for a full loin tuna, or tuna steaks, for a thick cut of tuna that is solid to grill. While you don't need to purchase sushi-grade tuna steaks, they will be the highest quality.
• Sesame oil – sesame oil has a rich, earthy flavor that ups the addictive quality of this recipe, and pulls out a hearty, meatier flavor of the tuna steak.
• Ginger – ginger provides a spicy kick to our dish, as well as a lightly sweet note that cuts through the salty soy sauce flavor.
• Soy sauce – soy sauce is a rich, earthy, salty sauce that is loaded with classic umami flavors – it helps enhance tuna steak's meaty flavor, and gives a dark, caramel appearance in a sauce. Soy sauce adds salt and black pepper flavor to the tuna.
• Garlic – garlic adds a pungent, earthy flavor to our sauce that adds a rich
• Rice vinegar – rice vinegar is light, slightly sweet, and a bit tart – helping to cut through the rich, salty soy sauce and fatty tuna flavor.
• Green onion – green onion provides a bright green color, light vegetal flavor, and is more subtle than onion – with a lightly earthy flavor.
• Sesame seeds – sesame seeds add crunch, help provide a crust for the tuna steaks to not stick to the grill grates, and get a good, earthy flavor that is almost peanut-like.

Sesame Grilled Tuna Instructions

Once you gather your ingredients, we will use the following method:

Prep & Marinate

First, combine the tuna, sesame oil, ginger, soy sauce, garlic, and green onion in a small bowl. Pour half into a large zip-top bag, save other half for sauce. Marinate for 30 minutes to 1 hour, turning the bag occasionally.

Grill

Preheat a grill or grill pan over medium-high heat. Spray with cooking spray.

Remove the tuna from the marinade and discard the marinade. Press tuna into sesame seeds on all sides.

Grill the tuna for 3 to 4 minutes per side, or until slightly pink in the center.

Serve

Sprinkle with sesame seeds, green onions, a squeeze of lemon juice, herbs, and serve with rice and veggies. Enjoy!

Kitchen notes

Don't overcook. Tuna is a forgiving fish that is fatty, so it can accept some overcooking and still taste great – but tuna steaks can be cooked rare to medium-rare (sear the outside, with a red middle) and be good.

How long to cook tuna steak. If you're going for a specific temperature, use our grilled tuna steak temperature guide below, to use with a digital meat thermometer:

• Rare: 120 – 130 degrees F.
• Medium Rare: 130 – 140 degrees F.
• Medium: 140 – 150 degrees F.
• Well: over 150F.

Don't flip too often. Flipping fish often can lead it to flake and fall apart – even fattier, thicker fish like tuna steaks. Flip only after each side has browned to reduce chances of tuna steaks breaking apart.

Marinate. Tuna steaks, even though they are thick and fattier than many types of fish, do best after marinating when grilled. Marinating locks in juices and adds flavor, and is an easy step that only requires 20 minutes before cooking – marinate as your grill heats if you forget to marinate earlier! Even a few minutes helps immensely.

Swap sesame as needed. If you are allergic to sesame oil, please skip it and swap for olive oil. You can replace the sesame seeds with crushed sliced almonds or pecans, or leave the tuna steaks without any kind of crust.

Make it keto. Swap soy sauce for coconut aminos to make this recipe keto diet approved.

Keeping leftovers

Leftover tuna steaks can be stored in an airtight container and kept in the refrigerator for up to two days.
