Learn how to sear sushi grade yellowfin tuna perfectly for a quick, healthy, and gourmet seafood dinner.

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 preferred)

Instructions

  1. Pat the ahi 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 acid can start to cook the fish.
  4. Spread the sesame seeds out on a plate. Remove the tuna from the marinade, letting any excess drip off, and press each side firmly into the sesame seeds until fully coated.
  5. Heat a heavy-bottomed skillet (cast iron works best) over high heat until it is very hot, almost smoking.
  6. 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 should be served rare in the center).
  7. Remove the tuna from the skillet immediately. Let the steaks rest on a cutting board for 5 minutes before slicing against the grain into 1/2-inch thick pieces.

Notes

  • For an extra layer of flavor, serve this quick seafood recipe with a side of soy sauce mixed with a little wasabi paste.
  • If you prefer a stronger crust, you can use only black sesame seeds.
  • This recipe works well with high-quality yellowfin tuna.
