Seared ahi is one of the fastest elegant dinners there is. The tuna is coated in sesame seeds, seared in a very hot pan just long enough to toast the seeds, and sliced to show a ruby-red center.

Because the center stays rare, buy tuna labeled sushi- or sashimi-grade from a trusted fish counter.

Ingredients

Tuna

  • 2 sushi-grade ahi tuna steaks (about 1 pound total), 1 1/2 inches thick
  • Salt and black pepper
  • 1/2 cup white and black sesame seeds
  • 2 tablespoons neutral oil

Dipping sauce

  • 1/4 cup soy sauce
  • 1 tablespoon rice vinegar
  • 1 teaspoon toasted sesame oil
  • 1 teaspoon grated ginger
  • 1 green onion, sliced
  • Wasabi and pickled ginger, for serving

Instructions

  1. Make the sauce. Stir the soy sauce, vinegar, sesame oil, ginger and green onion together.
  2. Coat. Pat the tuna dry, season with salt and pepper and press into the sesame seeds on all sides.
  3. Sear. Heat the oil in a skillet over high heat until shimmering. Sear the tuna 30 to 45 seconds per side, just until the seeds are golden.
  4. Slice and serve. Slice 1/4 inch thick with a sharp knife and serve with the sauce, wasabi and pickled ginger.

Tips

  • Keep the tuna very cold until it hits the pan for the rarest center.
  • A thicker steak gives a bigger red center.
