Making perfectly seared ahi tuna steaks is easier than you may think and the addition of a golden sesame seed crust takes it over the top! Ahi tuna sears quickly and doesn't require much for it to be totally delicious, so follow this recipe and you can serve a gourmet fish dinner at home!
To begin, place the sesame seeds, sugar, and seasonings on a shallow plate and mix them together.
2 tablespoon black sesame seeds, 2 tablespoon sesame seeds, 1 teaspoon coarse sugar, 1 teaspoon salt, ½ teaspoon ground black pepper, ½ teaspoon Italian seasoning
Pat your ahi tuna dry with paper towels, then brush soy sauce on all sides.
1 tablespoon soy sauce
Sprinkle the sesame blend generously over the tuna. Use your hands and gently, yet firmly, press the sesame coating into the fish. *Before proceeding, read ahead because the remaining steps will go very quickly.
12 oz ahi tuna
Heat a cast-iron skillet over medium-high heat and wait until it is VERY hot (*see note). Add your oil and coat the pan. Let it heat up until it's shimmering hot.
2 tablespoon cooking oil
Lay your ahi tuna in the pan carefully and press it down with your spatula. Sear for 45-60 seconds, then lift a corner of the fish to check the color. If golden, flip it over. Sear the opposite side for 60-90 seconds until golden.
Use tongs to hold the fish on its side so you may sear the edges. The edges will sear quickly, don't hold them to the pan for too long.
Transfer the cooked ahi tuna to a cutting board, slice it thinly, and serve right away.
