Ahi tuna, also known as yellow-fin tuna, is marinated in soy sauce, lemon juice, and sesame oil, then seared to perfection! Served rare, don’t let this sushi-style dish intimidate you. With a few simple ingredients, you can prepare this elegant meal in less than 30 minutes.
In a mixing bowl, whisk the first 8 ingredients (everything but oil and tuna steaks) for the marinade.
Place the tuna steaks on a rimmed pan or casserole dish, and pour marinade over the fish.
Marinate for 15 minutes, turning once halfway through the marinating process. Pour off the marinade from the fish.
Heat a few tablespoons of oil in a cast-iron skillet over medium-high heat, until shimmering.
Carefully place tuna steaks in the skillet with plenty of room between them. *
Sear 3 minutes per side. Carefully flip with tongs or a spatula.
Transfer fish to a large cutting board or plate, cover with foil, and allow to rest for 10 minutes.
Using a sharp knife (serrated is best), slice thinly across the grain (perpendicular to the natural lines across the fish).
Garnish with green onion and sesame seeds if desired. Serve chilled or at room temperature.
