Seared Ahi Tuna with Marinade
Seared Ahi Tuna with Marinade features fresh Ahi tuna steaks marinated in a mixture of soy sauce, sesame oil, garlic powder, sugar, lemon juice, salt, and pepper, then quickly seared on high heat to create a browned crust while maintaining a rare interior. The tuna is sliced thin and served chilled or at room temperature, optionally garnished with sesame seeds, green onions, and a drizzle of spicy mayonnaise for added flavor and texture.

Ingredients
For the Marinade
- 2 TB soy sauce or gluten-free tamari sauce
- 1 TB sesame oil found in the Asian aisle, Asian toasted
- 2 tsp garlic powder
- 2 tsp granulated sugar
- 1 tsp kosher salt
- 1 tsp black pepper freshly cracked
- 2 TB lemon juice freshly squeezed
For Ahi Tuna
- 2 ½ pounds Ahi Tuna steak about 1 1/2-1 2/3 inches thick, fresh
- 3 TB canola oil for searing, or vegetable oil
- cilantro green scallions, sesame seeds for garnish, freshly chopped, optional
- mayonnaise really good!, Sriracha flavored, for drizzling, optional
Instructions
- In a bowl, whisk together the marinade ingredients. This can be done in advance. Cover and chill until ready to use.
- Thoroughly dry ahi tuna steaks with paper towels and place in a glass or ceramic dish. Pour marinade over the fish, turning to coat well throughout. Cover tightly and chill several hours, or up to overnight. Turn fish over at least once in the middle of marinade time.
- Heat 3 TB oil in a large heavy skillet 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.)
- 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.
- Serve chilled or at room temp. Sprinkle with sesame seeds and cilantro or green onions, if desired. Drizzle with Sriracha mayo if desired.

Notes
- Do not marinate the tuna longer than overnight to protect its texture from the lemon juice.
- Use a heavy stainless steel or aluminum skillet for best searing results, avoiding nonstick pans.
- Rest the seared tuna before slicing to allow gentle finishing of cooking and maintain rare interior.
- Leftover tuna can be wrapped tightly and refrigerated for up to one day.
- For lower sodium, choose reduced sodium soy sauce; use gluten-free tamari to keep the dish gluten-free.
