Learn how to quickly sear sushi-grade Ahi tuna to achieve a warm, flavorful crust and a cool, rare center.

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. Pat the tuna steaks completely dry using paper towels. This step is key for a good sear.
  2. In a small bowl, whisk together the sesame oil, soy sauce, ginger, garlic, and black pepper to create the marinade.
  3. Place the tuna steaks in a shallow dish and pour the marinade over them, turning to coat both sides. Let them marinate for 10 minutes at room temperature. Do not marinate longer, as the soy sauce can begin to ‘cook’ the fish.
  4. Spread the sesame seeds on a plate. Remove the tuna from the marinade, letting excess drip off, and press all sides of the steaks firmly into the sesame seeds until fully coated.
  5. Heat a heavy-bottomed skillet, such as cast iron, over high heat until it is very hot. Add a small amount of high-heat oil if your pan is not non-stick, though the sesame oil in the marinade often suffices.
  6. Carefully place the coated tuna steaks in the hot skillet. Sear for 60 to 90 seconds per side for rare, or up to 2 minutes per side for medium-rare. You want a dark crust and a cool center.
  7. Remove the tuna from the pan immediately. Let the steaks rest on a cutting board for 5 minutes before slicing thinly against the grain.

Notes

  • Use only high-quality, sushi-grade yellowfin tuna for this recipe.
  • For serving, pair this with a simple soy-ginger dipping sauce or a bed of mixed greens.
  • If you prefer a spicier crust, mix a pinch of red pepper flakes into the sesame seeds.
