Grilled Tuna with Sesame Ginger Marinade

If you love seafood, then you’ll definitely enjoy these sesame ginger grilled tuna steaks!

The tuna is marinated in a delicious sesame ginger sauce, which adds a sweet and savory flavor to the fish that is delicious, rich, and out of this world.

Tuna is a great steak to grill, since it is thicker than a lot of seafood, so it won’t fall apart on the grill. Tuna’s fattier meat is also easier for beginner cooks to try grilling, since it is forgiving and less fussy – it doesn’t dry out as easily if slightly overcooked.

Plus, grilling the tuna steaks is quick and easy, making this dish perfect for a weeknight meal.

Serve with rice and veggies for a complete meal. We hope you enjoy this easy seafood dinner as much as we do!

How to Grill Sesame Ginger Tuna Steaks

Grilling tuna steaks is super 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 perfect 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 delicious, earthy flavor that is almost peanut-like.
  • First, combine the tuna, sesame oil, ginger, soy sauce, garlic, and green onion in a large zip-top bag. Marinate for 30 minutes to 1 hour, turning the bag occasionally.
  • Preheat a grill or grill pan over medium-high heat. Spray with cooking spray.
  • Remove the tuna from the marinade and discard the marinade. Grill the tuna for 3 to 4 minutes per side, or until slightly pink in the center.
  • Sprinkle with sesame seeds, green onions, a squeeze of lemon juice, herbs, and serve with rice and veggies. Enjoy!

Tips and Tricks to Perfect Sesame Ginger Grilled Tuna Steaks

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 delicious.

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.

For rare, cook to 120-130; medium-rare 130-140 degrees F.

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

How long can I keep tuna steaks?

Raw tuna steaks should be cooked one day after purchasing for the best flavor and freshness. Keep refrigerated until marinating, and let marinate in the refrigerator.

  1. Ronnie says:

    If grilling 4 tuna steaks do I just double the ingredients?

    1. Katherine says:

      Yes!

  2. Ann says:

    Amazing recipe. Does the recipe really call for 1 “tablespoon” of garlic powder? I only added 1 teaspoon and the tuna turned out delicious.

    1. Katherine says:

      Yes 1 tbsp will be a little spicier since the ginger adds that heat. So glad you enjoyed it!

  3. Adie says:

    This sounds delicious!
    I’m hoping to make it this weekend for my fish loving dad.
    Is it possible to make a sauce from the marinade rather than discarding it?

    1. Katherine says:

      If you want some sauce with it you can double the marinade. Add half the marinade to the raw fish and reserve the rest in the fridge. The next day you can boil the remaining marinade and add some cornstarch if you want it thicker. This should give you more of the flavor of the marinade. Hope this helps!

  4. Preyes says:

    This recipe made frozen tuna bought in the supermarket delicious!

    1. Katherine says:

      Thank you!

  5. David Street says:

    Hello Courtney, I just purchased 1 6oz. piece of sushi grade tuna to try myself, since my wife doesn’t care that much for tuna. My question is, can I use your recipe in a cast iron frying pan, instead of the grill?
    Thanks so much for your help! I look forward to receiving more of your recipes in the future.
    Respectfully yours,
    David S.

    1. Katherine says:

      Yes! If you want to pan fry your tuna steak simply heat about a tablespoon of olive oil in the cast iron skillet until it is very hot then sear on both sides. Tuna can be eaten raw but I go for a nice brown crust on the top and bottom when pan frying. Be aware it may smoke a lot in your house so open a window. Good luck!

  6. Adam Porter says:

    Combine with honey? Honey isn’t in the ingredients list! (How much?)

    1. Katherine says:

      Hi Adam, that was written in by mistake, the recipe doesn’t use honey, I fixed the issue, thank you for letting me know!
