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

  • Preheat the grill to medium-high heat (350°F).
  • In a small bowl, whisk together the olive oil, sesame oil, ginger, soy sauce, garlic powder, rice vinegar, and half of the sesame seeds.
  • Pour half of the marinade over the tuna steaks, reserving the rest for later. Cover and refrigerate for at least 20 minutes (or up to overnight) while the grill heats.
  • Once the grill is hot, remove the tuna steaks from the marinade and discard the excess marinade.
  • Coat the tuna steaks with 1 tablespoon of sesame seeds (or more if needed) to create a crust.
  • Place the tuna steaks on the grill and cook for 2-3 minutes per side, drizzling a bit of the reserved sauce on top while grilling.
  • For medium-rare tuna, cook until the internal temperature reaches 135°F. If you prefer well-done tuna, cook to 145°F.
  • Remove from the grill and top with the remaining sauce, green onions, and additional sesame seeds.
  • Serve immediately and enjoy!

Notes

Marinating time: Longer marination enhances the flavor, but 20 minutes is sufficient if you're short on time.
Cooking temperature: For a perfectly seared exterior and tender interior, aim for medium-rare (135°F). For well-done tuna, cook to 145°F.
Serving suggestions: Pair with steamed rice, stir-fried vegetables, or a fresh salad for a complete meal.
