Learn how to get a beautiful crust on sushi grade yellowfin tuna with this quick and easy Asian-inspired recipe.

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
  • 1/2 teaspoon black pepper
  • 1/4 cup sesame seeds (mixed black and white)

Instructions

  1. In a small bowl, whisk together the sesame oil, soy sauce, ginger, and minced garlic. This is your quick marinade.
  2. Place the tuna steaks in a shallow dish and pour the marinade over them. Turn the steaks to coat both sides evenly. Let them marinate for 10 minutes; do not marinate longer as the acid can start to cook the fish.
  3. Spread the sesame seeds out on a plate. Press each side of the marinated tuna steaks firmly into the seeds until they are completely coated.
  4. Heat a heavy-bottomed skillet, like cast iron, over high heat until it is very hot. You want the pan almost smoking.
  5. Carefully place the sesame-crusted tuna steaks into the hot, dry skillet. Sear for 60 to 90 seconds per side for rare to medium-rare (sushi grade tuna cooks very fast).
  6. 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 an extra flavor boost, mix 1 teaspoon of rice vinegar into your dipping sauce.
  • If you like your tuna cooked slightly more, add 15 seconds to each side, but remember that overcooking ruins the texture of quality ahi.
  • Serve this gourmet tuna with a side of steamed rice and sliced avocado for a complete healthy dinner.
