A quick and simple recipe for perfectly seared ahi tuna steaks with a caramelized crust and rare, ruby-red interior, ideal for busy weeknights or dinner parties.

Ingredients

Scale
  • 2 ahi tuna steaks (about 6 oz / 170 g each, sashimi-grade preferred)
  • 1 tablespoon sesame oil (or grapeseed oil as a neutral alternative)
  • 2 tablespoons soy sauce (low sodium preferred)
  • Freshly ground black pepper to taste
  • Pinch of sea salt or flaky salt
  • 2 tablespoons crushed black and white sesame seeds (optional)
  • 1 teaspoon finely grated fresh ginger (optional)
  • Light sprinkle of garlic powder (optional)
  • Fresh lime or lemon wedges for serving

Instructions

  1. Pat the tuna steaks dry with paper towels to remove excess moisture (about 2 minutes).
  2. Season both sides lightly with sea salt and freshly ground black pepper. If using sesame seeds, press them gently onto both sides for a coating (1-2 minutes).
  3. Mix soy sauce, sesame oil, grated ginger, and garlic powder in a small bowl and set aside (2 minutes).
  4. Heat a heavy-bottomed skillet or cast iron pan over medium-high heat until very hot, about 3-4 minutes, until oil shimmers.
  5. Add a teaspoon of sesame oil to the pan, then place the tuna steaks carefully. Cook without moving for exactly 1 minute for a 1-inch thick steak to form a golden crust.
  6. Flip the steaks gently and cook the other side for 45 seconds to 1 minute to keep the center restaurant rare.
  7. Remove the steaks from the pan and let rest on a cutting board for 2 minutes to redistribute juices.
  8. Slice into half-inch slices against the grain, drizzle with the soy-sesame sauce, and serve with lime wedges (3 minutes).

Notes

If tuna steaks are thicker than 1 inch, increase searing time by 15-30 seconds per side. Avoid overcooking to maintain the rare center. Use a hot pan and dry the tuna well for a crisp crust. Can swap soy sauce for tamari for gluten-free option. Let tuna rest before slicing for best texture.
