Ingredients

Scale

2 Ahi Tuna Steaks
2 tbsp Olive Oil
1 tbsp Soy Sauce
1 tsp Sesame Oil
½ tsp Garlic Powder
¼ tsp Black Pepper
To taste Salt
Sesame seeds
Sliced green onions

Instructions

  1. Gently pat your ahi tuna steaks dry with paper towels
  2. In a shallow dish or a Ziploc bag, combine the olive oil, soy sauce (or tamari), sesame oil, garlic powder, black pepper, and salt. Whisk everything together until well combined
  3. Place the dried tuna steaks into the marinade. Turn them to coat evenly. Allow the tuna to marinate for 10-15 minutes at room temperature. Avoid marinating for longer than 30 minutes, as the acidity can start to "cook" the delicate fish
  4. While the tuna marinates, preheat your grill to medium-high heat (about 400-450°F or 200-230°C). Make sure the grill grates are clea
  5. Lightly oil the hot grill grates to prevent sticking. You can do this by folding a paper towel, dipping it in a little vegetable oil, and carefully wiping the grates using tongs
  6. Carefully place the marinated tuna steaks on the hot, oiled grill. For a rare to medium-rare doneness (which is ideal for ahi tuna), cook for 1.5 to 2 minutes per side. For a medium doneness, cook for 3-4 minutes per side
  7. The best way to check doneness is with an instant-read thermometer. For rare, aim for 115-120°F (46-49°C). For medium-rare, 125-130°F (52-54°C). For medium, 135-140°F (57-60°C). The edges will be opaque, and the center will be pink
  8. Once cooked to your desired doneness, remove the tuna from the grill. Place it on a clean plate and let it rest for 5 minutes. This allows the juices to redistribute, resulting in a more tender and flavorful steak
  9. Slice the tuna against the grain into ½-inch thick pieces, if desired. Garnish with sesame seeds and sliced green onions for an extra flourish. Serve immediately

Notes

For best results, use high-quality, fresh ahi tuna with a vibrant red color and firm texture.

Patting tuna steaks dry thoroughly before marinating is crucial for a good sear.

Do not marinate ahi tuna for longer than 10-15 minutes to avoid a mushy texture.

Ensure your grill is preheated to medium-high (400-450°F / 200-230°C) with clean, oiled grates to prevent sticking and achieve a perfect sear.

Cook for 1.5-2 minutes per side for rare to medium-rare (internal temp 125-130°F), or 3-4 minutes per side for medium. Use an instant-read thermometer.

Rest the tuna for 5 minutes after grilling to allow juices to redistribute, ensuring a tender and flavorful steak.

For a gluten-free option, use Tamari instead of soy sauce.

Store leftover grilled tuna in an airtight container in the refrigerator for up to 2-3 days. Reheat gently in a 275°F (135°C) oven for 5-10 minutes, or in a skillet over low heat, to avoid drying it out. Avoid microwaving.
