Ahi tuna is type of tuna that is divided into two different species: yellowfin and bigeye. And its often cheaper than bluefin tuna, with a very similar flavor profile and texture. You can usually find it frozen at Trader Joes or your local grocery store for very inexpensive.

It actually looks very similar to a beef steak in this regard. It. Is. AMAZING.
Ahi Tuna Steak Basics
Here are the basics steps for preparing Ahi Tuna Steak at home:
Buy the fish. Get your hands on some fresh, sushi-grade Ahi Tuna filets.
Take your fish out of the refrigerator. Prepare the marinade and cover the fish with it. Set it aside and let it marinate for about 20-25 minutes. This will allow the fish to come closer to room temperature and absorb some of the marinade flavors.
Sear the fish. Heat up a non-stick or cast iron skillet over very high heat. Place the steak and sear for about 1-3 minutes on each side, or until the steak reaches the desired doneness. When searing Ahi Tuna steaks, it is important not to overcook them the fish tastes best when rare in the center .
Serve the fish. Cut the Ahi Tuna steaks against the grain into ½-inch thick slices. Drizzle with the reserved marinade.

- Before cooking tuna steaks, check for scales. If any are present, rinse with cool water. Pat dry with paper towels.
- Measure the thickness of the fish with a ruler, so you know how long to cook tuna steak.
- Fresh tuna steaks love a good marinade recipe, which flavors this fairly mild fish and helps keep it moist during cooking. A short marinating time is all it needs, from 15 minutes to 4 hours in the refrigerator. Tuna pairs especially well with Asian-inspired flavors.
- Instead of marinating, you can brush the fish with olive oil or melted butter and season as desired. For example, try brushing tuna with olive oil and lemon juice, then sprinkle it with snipped fresh herbs , salt, and ground black pepper. Or try one of these delicious spice blends.

What Is Sushi Grade Tuna
Sushi grade or sashimi-grade tuna is fish that can be safely eaten raw. It is usually processed on the boat and flash frozen to prevent parasites.
Most grocery stores will indicate that the tuna is sushi grade. If not, ask if it is considered sushi grade. Although we are not going to be eating raw tuna, it will be quickly seared and be rare in the middle.
Ive never had a problem with the tuna I have bought even though it wasnt labeled sashimi or sushi-grade ahi tuna.
The best tuna will have a deep pink or red color. Lesser grades will look light pink and translucent and should be avoided.
Dry Oil And Then Season The Tuna
While your grill is preheating, you can prep your fish. It’s important to dry the fish well on both sides, using paper towelsminimizing surface moisture helps speed the searing process along and reduces the chances of the tuna sticking to the grill.
To that end, I also like to lightly rub the dried steaks with a neutral oil like canola or vegetable oil. It’s just one more bit of insurance against sticking.
Salt draws moisture out of proteins like fish and other meats, so I make sure to sprinkle it on the tuna at the last second. After we’ve made sure to dry the surface of the fish well, the last thing we want to do is get it wet again before putting it on the grill.

Does Ahi Tuna Steak Need To Be Cooked Through
Sushi grade tuna, such as Ahi Tuna, is generally not cooked through in the sense of being well-done it is almost always served medium-rare. The searing should cause the outer inch or so of the tuna to be cooked all around, with a nice pink interior.
However, if you dont like medium-rare tuna, you can cook it longer just until the interior begins to change color and is no longer translucent. Dont overcook, or the tuna will be tough, dry, and hard to chew.
Is Ahi Tuna Steak Healthy
