What's Ahi Tuna?
There are four widely consumed varieties of tuna: Albacore, Bluefin, Skipjack, and Yellowfin tuna. Yellowfin tuna (a.k.a. Ahi Tuna) is a species of tuna found in the pelagic waters of tropical and subtropical oceans worldwide. The fish have pink flesh with a mild flavor.
Where to Buy Ahi Tuna Steak?
Depending on where you live, you might have difficulties finding some good Ahi Tuna steaks. Because it’s best to keep the middle of the steaks raw, you’ll need some fresh sushi-grade tuna. The best place to buy it is at a popular local fish market. Just do a quick Google search and find a fish market in your area that has good reviews.
If there are no good fish markets in your area, you may opt for frozen Ahi Tuna. To be honest, the difference between fresh and frozen tuna is noticeable, so I always prefer the fresh ones.
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.
Marinate the fish. 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 (preferred) or cast iron skillet over very high heat. Place the steak(s) 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 (but of course, cook to your liking).
Serve the fish.Cut the Ahi Tuna steaks against the grain into ½-inch thick slices. Drizzle with the reserved marinade.
I absolutely love this marinade on my Ahi Tuna steak. It has a great balance of sweet and sour, and adds a ton of flavor. The marinade is made with a few ingredients:
- Olive Oil
- Maple Syrup
- Lemon Juice
- Dijon Mustard
I use this marinade to drizzle on top of the steak, once it's cooked, too. Very tasty!
How to Make Ahi Tuna Steak:
1. Take the Ahi Tuna out of the refrigerator. Remove the packaging, and set aside.
2. In a large dish, mix all of the marinade ingredients together. Reserve about four tablespoons of the marinade. Add the tuna steaks to the dish, and turn them until they’re well-coated. Set aside, and let them rest at room temperature for about 20-30 minutes.
3. Heat up a non-stick skillet over high heat. Sear the tuna steaks for about
1-3 minutes on each side, or until the steaks reach their desired doneness.*
4. Place the cooked steaks on a cutting board, and slice against the grain into ½-inch thick slices. Transfer the steak slices to a serving plate and drizzle with the reserved maple-mustard marinade. Serve immediately.
*It is best to leave the middle of the tuna steak raw. Searing time will depend on your personal preference and on how thick your tuna steaks are. I like to stay and watch the steaks closely while searing. It is easy to see how the steak changes color as it cooks, so when it looks like it’s 25% cooked on the bottom, I flip it and cook it for the same amount of time on the other side.
