Learn to sear sushi-grade ahi tuna quickly for a flavorful, healthy dinner with an Asian-inspired crust.

Ingredients

Scale
  • 2 (6 ounce) sushi grade ahi tuna steaks
  • 2 tablespoons sesame oil
  • 1 tablespoon soy sauce or tamari
  • 1 teaspoon grated fresh ginger
  • 1 clove garlic, minced
  • 1 tablespoon black sesame seeds
  • 1 tablespoon white sesame seeds
  • Pinch of black pepper

Instructions

  1. In a small bowl, whisk together the sesame oil, soy sauce, ginger, and garlic. Brush this mixture evenly over all sides of the tuna steaks.
  2. Combine the black sesame seeds, white sesame seeds, and black pepper on a small plate. Press each side of the tuna steaks firmly into the seed mixture to coat them completely.
  3. Heat a heavy-bottomed skillet (cast iron works well) over high heat until it is very hot, about 3 to 4 minutes. Do not add oil to the pan, as the marinade already contains oil.
  4. Carefully place the crusted tuna steaks in the hot, dry skillet. Sear for 60 to 90 seconds per side for rare to medium-rare. The goal is a dark, crisp crust with a cool, raw center.
  5. Remove the tuna from the pan immediately. Let the steaks rest on a cutting board for 5 minutes before slicing against the grain into half-inch thick pieces.

Notes

  • For best results, remove the tuna from the refrigerator 15 minutes before cooking to allow it to come closer to room temperature.
  • If you prefer your tuna cooked slightly more, reduce the searing time to 45 seconds per side.
  • Serve this dish with a side of steamed rice and blanched green beans for a complete meal.
