Ingredients

Ahi Tuna Steaks

  • 2 ahi tuna (yellowfin tuna) steaks (about 4 oz. each, 1″ thick)

Marinade

  • 2 tablespoons soy sauce (preferably low sodium)
  • 1 tablespoon toasted sesame oil
  • 1 tablespoon honey
  • ½ teaspoon kosher salt (optional)
  • ¼ teaspoon black pepper
  • ¼ teaspoon cayenne pepper (optional)

For Searing

  • 1 tablespoon oil (canola, olive, or other high-heat cooking oil)

For Serving (Optional)

  • Green onions
  • Toasted sesame seeds
  • Lime wedges

Instructions

  1. Prepare the Tuna: Pat the ahi tuna steaks dry with a paper towel to remove excess moisture. Place the steaks on a plate or inside a plastic bag, ready for marination.
  2. Make and Apply Marinade: In a bowl, mix soy sauce, toasted sesame oil, honey, kosher salt (if using), black pepper, and cayenne pepper until the honey dissolves completely. Pour this mixture over the tuna steaks, turning them to coat evenly. Optionally, marinate for at least 10 minutes up to overnight in the refrigerator. Reserve some marinade for drizzling after cooking if desired.
  3. Heat the Skillet: Preheat a medium skillet (non-stick or well-seasoned cast iron preferred) over medium-high to high heat until very hot. For cast iron, allow 3-5 minutes; for non-stick, about 1 minute depending on thickness.
  4. Sear the Tuna: Add oil to the hot pan and sear the tuna steaks for 1 to 1½ minutes on each side for medium-rare doneness. Adjust cooking time for desired doneness: 30 seconds per side for very rare, 2 to 2½ minutes for medium-well to well done. Use medium to medium-high heat for non-stick pans to prevent burning the marinade.
  5. Slice and Serve: Remove the tuna from the skillet and transfer to a cutting board. Slice into ½ inch slices and arrange on a serving plate. Garnish with green onions, toasted sesame seeds, and lime wedges if desired. Sprinkle with flaky sea salt to taste, if needed.

Notes

  • For thinner or thicker tuna steaks, adjust searing times accordingly to avoid overcooking or undercooking.
  • Using low sodium soy sauce helps control salt levels in the dish.
  • Marinating overnight enhances flavor but is optional; a minimum of 10 minutes is sufficient for quick preparation.
  • Use a well-seasoned cast iron skillet or non-stick pan to avoid sticking and achieve a good sear.
  • Adjust heat carefully to prevent the marinade from burning.
  • Flaky sea salt sprinkled after cooking enhances flavor without making it too salty.
