Sesame Ahi Tuna

4 Servings
2 hr 3 min

This meal was a real treat! A friend caught a tuna and gifted some of it. Part of the tuna was sliced thinly to create a sashimi appetizer. The rest was cut into steaks which were marinated and coated in sesame seeds to create this delicious dinner. Even raw fish skeptics tried the dish and fell in love.

The marinade will help the sesame seeds stick to the tuna. Make sure to coat the tuna steaks all over with the seeds, as many will fall off during the cooking process. Not only do they add flavor, but they add a nice texture to the fish.

Slicing the tuna against the grain will give you a more tender slice. The tuna should be just warm inside and seared on the outside. Drizzle the soy dipping sauce all over your platter or pass a bowl and let people add what they want.

  • It’s important to use quality tuna when making a dish that’s seared like this. The tuna shouldn’t smell “fishy”. Get to know your fish monger and buy when the fish has just arrived. Or friend a fisherman.
