Learn how to perfectly sear sushi-grade Ahi tuna for a quick, healthy, and flavorful meal.

Ingredients

Scale
  • 2 (6 ounce) sushi grade Ahi tuna steaks
  • 2 tablespoons soy sauce
  • 1 tablespoon sesame oil
  • 1 teaspoon grated fresh ginger
  • 1 clove garlic, minced
  • 1 tablespoon olive oil
  • 1 teaspoon black sesame seeds
  • 1 teaspoon white sesame seeds

Instructions

  1. In a shallow dish, whisk together the soy sauce, sesame oil, ginger, and garlic. This is your marinade.
  2. Place the tuna steaks in the marinade. Turn to coat both sides. Let the tuna marinate for 10 minutes. Do not marinate longer, as the soy sauce can begin to cure the fish.
  3. While the tuna marinates, mix the black and white sesame seeds together on a small plate.
  4. Remove the tuna from the marinade, letting excess drip off. Press both sides of each steak into the sesame seed mixture to coat evenly.
  5. Heat the olive oil in a heavy skillet (cast iron works well) over medium-high heat until the oil shimmers.
  6. Carefully place the coated tuna steaks in the hot skillet. Sear for 1 to 1.5 minutes per side for rare (cool, raw center) or 2 minutes per side for medium-rare.
  7. Remove the tuna from the skillet immediately. Let the steaks rest on a cutting board for 3 minutes.
  8. Slice the tuna against the grain into half-inch thick pieces. Serve right away.

Notes

  • For a dipping sauce, mix equal parts soy sauce and rice vinegar with a small dash of sriracha.
  • If you prefer a warmer center, you can cook the tuna for an extra minute per side, but avoid overcooking to keep the texture tender.
  • Use only sushi-grade or sashimi-grade tuna when preparing this dish raw in the center.
