Grilled Tuna Steaks

Tuna steaks can be a bit tricky to justify buying and preparing at home, primarily because of how easy it is to not cook it right.

Just like with beef steaks, tuna steaks can go from flaky and tender to rubbery and chewy in under a minute if you aren’t watching carefully.

However, thanks to this tangy marinade, it might not be that big of a problem – so long as you take the time to ensure the marinade penetrates the flesh and  keep an eye on the fish while on the grill, you should be able to end up with delicious and tender tuna, even if they end up a little over cooked.

How To Get The Right Doneness In Your Tuna Steak

Tuna is one of those challenging fishes to get right, because it is capable of becoming pretty unpleasant and tough if you aren’t careful when cooking it.

In fact, tuna steaks are a lot like regular steaks, in that the longer you cook them, the drier and less supple and juicy the inside becomes.

If you want to enjoy a slightly more well done tuna steak, feel free to leave your tuna on the grill for a little bit longer than in this recipe, as this will ensure a more cooked interior.

If you are struggling with burning the surface of your fish, though, try flipping it a few times as it cooks those last few minutes necessary to get the doneness that you want.

Flipping frequently is a great way to ensure that the surface doesn’t burn, as well as making sure that the interior of the meat cooks really evenly.

You can also gauge the doneness of your tuna steaks by giving them a little poke as they cook. The old thumb test that you would use for a steak works really well with fish also.

Simply spread out the palm of your hand and touch one finger of the same hand at a time onto the muscle at the base of your thumb.

The index finger hitting the muscle will feel like rare, the middle finger will feel like medium rare, the ring finger will feel like medium and your pinkie finger touching the muscle will feel like well done.

Use that simple guide to see how far along you are in cooking time, allowing you to prepare your tuna steaks however you prefer them.

Could You Use A Different Fish For This Recipe?

This recipe produces a really delicious piece of fish to enjoy as the main protein for a big family dinner, a perfect beef replacement for those looking to cut back on red meat.

However, one of the big problems with tuna is that it can be pretty pricey, so not everyone is going to want to always splurge for a big piece of fish.

Instead of using a big piece of tuna that might not necessarily be easy to get a hold of, feel free to substitute it for something else.

Any other type of fish with a thick, firm flesh would work here. Something like swordfish would be a perfect replacement, but that is obviously usually a lot more expensive than tuna anyway.

Instead, why not try looking for a good thick cut piece of salmon. Though still not completely cheap, salmon is capable of holding up to the bold flavors in this marinade, ensuring a tasty fish steak even if it doesn’t have the exact meatiness of tuna.

  • Add the tuna steaks and tun to coat them well.
  • Cover the glass dish and refrigerate for 30 minutes turning the steaks halfway through to re coat with the marinade.

Recipe Notes

If you don’t like rare fish, you can grill the tuna a little longer until it is opaque throughout. The tuna will not be as tender, and its texture will be more like a well-done steak, but it will still taste delicious. Make sure not to overcook the tuna or it will become tough.
