Marinated Seared Ahi Tuna

Step 1

In a bowl, whisk together the first 7 ingredients to make the marinade.* Towel dry tuna steaks and place in a glass or ceramic dish. Pour marinade over the fish, turning to coat well throughout. Cover tightly and chill several hours, up to overnight; turn fish over at least once in the middle of marinade time.

Step 2

Heat 3 TB oil in a large heavy skillet - use aluminum or stainless steel; not nonstick, as it won't sear - until oil is smoking. Sear ahi steaks 1 1/2 minutes per side on high heat, taking care to flip carefully with a flat, steel spatula. (If your tuna is less than 1 1/2 inches thick, sear for only 1 minute per side.)

Step 3

Transfer seared ahi to a large cutting board and let rest/cool 10 minutes. Use a very sharp (serrated works well) knife to slice thinly across the grain.

Step 4

Serve chilled or at room temp. Sprinkle with sesame seeds and cilantro or green onions, if desired. Drizzle with Sriracha mayo if desired.
