Ingredients
Scale
Tuna and Crust
- 1 pound sushi-grade ahi tuna steaks (about 1-inch thick)
- 2 tablespoons sesame oil
- 3 tablespoons black sesame seeds
- 3 tablespoons white sesame seeds
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
Soy Ginger Sauce
- 1/4 cup low-sodium soy sauce
- 2 tablespoons rice wine vinegar
- 1 tablespoon fresh ginger, finely grated
- 1 teaspoon honey
- 1/2 teaspoon sesame oil
Garnishes and Extras
- 1 avocado, sliced
- 2 scallions, thinly sliced
- 1 cucumber, julienned
- Pickled ginger (optional)
- Wasabi (optional)
Instructions
- Prepare the Tuna: Remove the sushi-grade ahi tuna from the refrigerator 15-20 minutes before cooking to bring it closer to room temperature. Pat the steaks completely dry with paper towels to ensure a perfect sear. Lightly brush all sides with sesame oil.
- Create the Sesame Crust: In a shallow dish, combine black sesame seeds, white sesame seeds, kosher salt, and black pepper. Mix them evenly. Press each tuna steak firmly into the mixture, coating all sides generously to help the seeds stick through the sesame oil.
- Make the Soy Ginger Sauce: In a small bowl, whisk together soy sauce, rice wine vinegar, grated ginger, honey, and sesame oil until the honey dissolves. Taste and adjust the balance of sweet and tangy to your preference.
- Heat Your Pan: Place a heavy-bottomed skillet or cast-iron pan over medium-high heat. Let it get very hot until a drop of water sizzles and evaporates immediately. Do not add oil to the pan since the tuna is already coated in sesame oil.
- Sear the Tuna: Place the tuna steaks gently in the hot pan and hear an immediate sizzle. Sear each side for 1-2 minutes, depending on thickness, until a golden-brown crust forms while keeping the center cool and pink. Do not move or press the tuna during searing.
- Rest and Slice: Remove the tuna steaks from the pan and let rest on a cutting board for 1 minute. Using a very sharp knife, slice against the grain into 1/4-inch thick slices. Clean the knife between cuts for the best presentation.
Notes
- Bring tuna to room temperature before cooking for an even sear.
- Patting the fish dry is essential to achieve a crisp crust without steaming.
- Press sesame seeds firmly onto the tuna to prevent them from falling off during cooking.
- Use a heavy skillet like cast iron for best heat retention and even cooking.
- Do not overcook; ahi tuna is best served rare to medium-rare in the center.
- Adjust the soy ginger sauce sweetness or acidity according to taste.
- Serve with fresh avocado, scallions, cucumber, and optional pickled ginger and wasabi for authentic flavors.
