Ingredients

Scale

Main Ingredients

  • 2 fresh sushi-grade ahi tuna steaks (about 1 to 1.5 inches thick)
  • 2 tablespoons olive oil, divided
  • 2 tablespoons soy sauce
  • 1 tablespoon freshly grated ginger
  • 2 cloves garlic, minced
  • 1 tablespoon lime juice
  • 2 tablespoons sesame seeds
  • Sea salt, to taste
  • Black pepper, to taste

Instructions

  1. Prepare the Tuna Steaks: Pat the fresh ahi tuna steaks dry with paper towels to ensure a perfect sear. Lightly season both sides with sea salt and black pepper to enhance the fish’s natural flavors.
  2. Marinate the Tuna: In a small bowl, whisk together olive oil, soy sauce, freshly grated ginger, minced garlic, and lime juice. Place the tuna steaks in a shallow dish and pour the marinade over them. Let the steaks sit for about 10 minutes to absorb the flavors without overpowering the delicate fish.
  3. Coat with Sesame Seeds: After marinating, gently press both sides of each tuna steak into a plate of sesame seeds to create a crunchy and aromatic coating that browns beautifully when seared.
  4. Heat the Pan and Sear: Preheat a heavy-bottomed skillet or cast-iron pan over medium-high heat until very hot. Add a small amount of olive oil to coat the pan. Sear each tuna steak for 1.5 to 2 minutes on each side, aiming for a nicely browned crust while keeping the inside rare, soft, and pink.
  5. Rest and Slice: Remove the tuna steaks from the pan and allow them to rest for a couple of minutes to redistribute the juices. Slice the tuna into half-inch thick pieces, cutting against the grain for optimal tenderness and presentation.

Notes

  • Use fresh, sushi-grade tuna for the best tenderness and flavor.
  • Do not overcook; serve tuna rare to medium-rare to avoid dryness.
  • Preheat your pan thoroughly for a quick sear and caramelized crust.
  • Dry the tuna before searing to prevent steaming and ensure browning.
  • Let the tuna rest after cooking to keep it juicy and moist.
