Ingredients
  

  • 2 ahi tuna steaks about 1 to 1.5 inches thick
  • 2 tbsp soy sauce
  • 1 tsp toasted sesame oil
  • 1 clove garlic minced
  • 1/2 tsp fresh ginger grated
  • 1/2 lime juiced
  • salt and black pepper to taste
  • 1 tbsp neutral oil for grill grates
  • 1 tbsp sesame seeds for garnish
  • 2 tbsp scallions sliced for garnish

Equipment

  • grill
  • mixing bowl
  • whisk
  • Tongs
  • paper towels

Method
 

  1. In a small bowl whisk together soy sauce, sesame oil, minced garlic, grated ginger, and lime juice until well combined.
  2. Place the tuna steaks in a shallow dish and pour the marinade over them. Turn to coat and let sit at room temperature for 15–20 minutes.
  3. Heat the grill to high heat around 450–500°F. Clean the grates thoroughly.
  4. Remove the tuna from the marinade and gently pat dry with paper towels. Season lightly with salt and black pepper if desired.
  5. Using tongs, rub a paper towel dipped in neutral oil over the grill grates just before cooking.
  6. Place the tuna steaks directly over high heat and grill for about 2 minutes on the first side without moving. Flip once and grill for 90 seconds to 2 minutes on the second side for medium-rare.
  7. Transfer to a cutting board and rest for 2 minutes. Slice or serve whole, then garnish with sesame seeds, sliced scallions, and an extra squeeze of lime.

Notes

For best results, use sushi-grade tuna and avoid overcooking — aim for a medium-rare center. Always pat the tuna dry before grilling to achieve a proper sear. Marinate briefly (15–20 minutes) to enhance flavor without breaking down the texture.
