Learn how to sear sushi grade yellowfin tuna perfectly every time 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 for gluten-free)
  • 1 teaspoon grated fresh ginger
  • 1 clove garlic, minced
  • 1/2 teaspoon black pepper
  • 1/4 cup sesame seeds (mixed black and white for best look)

Instructions

  1. In a small bowl, whisk together the sesame oil, soy sauce, grated ginger, minced garlic, and black pepper. This is your quick marinade.
  2. Place the ahi tuna steaks in a shallow dish and pour the marinade over them. Turn the steaks to coat evenly. Let them marinate for 10 minutes at room temperature. Do not marinate longer, as the soy sauce can start to cure the fish.
  3. Spread the sesame seeds out on a plate in a thin, even layer.
  4. Remove the tuna from the marinade, letting any excess drip off. Gently press both sides of each tuna steak into the sesame seeds until they are fully coated.
  5. Heat a heavy-bottomed skillet (cast iron works best) over high heat until it is very hot, almost smoking. This high heat is key for a good sear.
  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. You want a deep, golden-brown crust and a cool, deep red center.
  7. Remove the tuna from the skillet immediately. Let the steaks rest on a cutting board for 5 minutes before slicing.
  8. Slice the tuna against the grain into half-inch thick pieces. Serve right away.

Notes

  • For an extra layer of flavor, serve this seared ahi tuna with a drizzle of low-sodium soy sauce or a light ponzu sauce.
  • If you prefer your tuna cooked slightly more, add 15 to 30 seconds to the searing time per side, but avoid cooking past medium, as the texture changes significantly.
  • You can use a mix of spices instead of sesame seeds, such as blackening seasoning, for a different flavor profile.
