Prep: 10 Cook: 4
Ingredients
  • 4 steaks (150g each) sushi-grade ahi tuna steaks
  • 120ml mixed black and white sesame seeds
  • 60ml soy sauce
  • 15ml wasabi paste
  • 30ml toasted sesame oil
Instructions
  1. Pat 4 steaks (150g each) sushi-grade ahi tuna steaks steaks completely dry with paper towels. This is crucial for a good sear. Season lightly with salt.

  2. Spread 120ml mixed black and white sesame seeds on a plate. Press each tuna steak firmly into the seeds, coating all sides evenly. The seeds should stick to the fish.

  3. In a small bowl, whisk together 60ml soy sauce, 15ml wasabi paste, and half the 30ml toasted sesame oil to create a dipping sauce. Set aside.

  4. Heat remaining sesame oil in a large skillet over high heat until almost smoking. The pan must be very hot for proper searing.

  5. Carefully place tuna steaks in the pan and sear for 60-90 seconds per side for rare, or up to 2 minutes for medium-rare. The center should remain raw.

  6. Transfer immediately to a cutting board and slice into 1cm (1/2-inch) thick slices. Serve with the wasabi-soy dipping sauce.

Tips

Tuna Quality: Only use sushi-grade ahi (yellowfin) tuna from a reputable source. The fish should be deep red with no fishy smell.

Sesame Coating: Mix equal parts black and white sesame seeds for visual appeal, or use all white. Press firmly for good adhesion.

Doneness: Ahi tuna is best served rare to medium-rare. The center should be cool and red. Overcooking makes it dry and loses the buttery texture.

Serving Suggestions: Serve over Asian slaw, seaweed salad, or sushi rice. Garnish with pickled ginger and wasabi.

Wasabi Alternative: If wasabi is too strong, substitute with grated fresh ginger or omit entirely. The dipping sauce is still delicious.

Storage: This dish is best served immediately. Leftover tuna can be refrigerated for 1 day and enjoyed cold in poke bowls or salads.
