Ingredients

  • 2 tuna steaks
  • 2 tablespoons olive oil
  • 1 teaspoon sesame oil
  • 1 teaspoon ground ginger
  • 1 tablespoon soy sauce
  • 1 teaspoon garlic powder
  • 1 tablespoon rice vinegar
  • 2 tablespoons sesame seeds divided
  • Green onion sliced (for garnish)

Instructions

  • Prepare the Marinade
  • In a small bowl, whisk together olive oil, sesame oil, ground ginger, soy sauce, garlic powder, rice vinegar, and half of the sesame seeds.
  • Marinate the Tuna
  • Pour half of the marinade over the tuna steaks and reserve the remaining marinade.
  • Cover and refrigerate for at least 20 minutes (or up to overnight).
  • Preheat the Grill
  • Preheat your grill to medium-high heat (about 350°F).
  • Coat the Tuna
  • Remove the tuna steaks from the marinade and discard the used portion.
  • Coat the tuna with 1 tablespoon (or more) of sesame seeds to form a crust.
  • Grill the Tuna
  • Place tuna steaks on the hot grill. Cook for 2–3 minutes per side.
  • Drizzle a little of the reserved marinade over the steaks while grilling.
  • For medium-rare, cook until the internal temperature reaches 135°F. For well-done, cook to 145°F as per FDA guidelines.
  • Serve and Enjoy
  • Remove from the grill. Top with remaining marinade, sliced green onions, and additional sesame seeds.
  • Serve immediately.
  • Notes
  • Marinating longer enhances flavor, but 20 minutes is sufficient if short on time.
  • For tender, medium-rare tuna, cook to 135°F; cook to 145°F for well-done.
  • Pairs well with rice, stir-fried vegetables, or salad for a complete meal.
