Learn how to quickly sear sushi grade tuna for a delicious, healthy dinner with an Asian flavor profile.

Ingredients

Scale
  • 2 (6 ounce) sushi grade tuna steaks (yellowfin or bigeye)
  • 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 tablespoon sesame seeds (for coating)

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, and minced garlic. Brush this mixture evenly over all sides of the tuna steaks.
  3. Place the sesame seeds on a shallow plate. Press each side of the tuna steaks into the seeds to coat them lightly.
  4. Heat a heavy-bottomed skillet (cast iron works well) over high heat until it is very hot. You should see a slight wisp of smoke.
  5. Carefully place the coated tuna steaks into the hot, dry skillet. Sear for 60 to 90 seconds per side for rare to medium-rare. Do not move the fish while searing.
  6. Remove the tuna from the skillet immediately. Let the steaks rest on a cutting board for 5 minutes before slicing thinly against the grain.

Notes

  • For a dipping sauce, mix 2 tablespoons soy sauce, 1 teaspoon rice vinegar, and a pinch of red pepper flakes.
  • If you prefer a slightly more cooked center, increase the searing time to 2 minutes per side.
  • Use only high-quality, sushi grade tuna for this quick seafood recipe.
