Learn how to grill sushi-grade tuna steaks to a perfect medium-rare using this simple guide and a flavorful sesame ginger glaze.

Ingredients

Scale
  • 2 (6-ounce) sushi-grade Ahi tuna steaks, about 1.25 inches thick
  • 1 tablespoon olive oil
  • 1 teaspoon coarse salt
  • 1/2 teaspoon black pepper
  • For the Glaze:
  • 3 tablespoons soy sauce
  • 2 tablespoons rice vinegar
  • 1 tablespoon honey
  • 1 teaspoon grated fresh ginger
  • 1 clove garlic, minced
  • 1 teaspoon sesame oil
  • 1 teaspoon toasted sesame seeds, for garnish

Instructions

  1. Remove the tuna steaks from the refrigerator 20 minutes before grilling. Pat the steaks completely dry using paper towels; this helps achieve a good sear.
  2. Prepare the glaze: In a small bowl, whisk together the soy sauce, rice vinegar, honey, ginger, garlic, and sesame oil. Set aside.
  3. Preheat your grill to high heat (about 450-500 degrees Fahrenheit). Clean the grates well and lightly oil them to prevent sticking.
  4. Brush the tuna steaks lightly with olive oil. Season both sides evenly with salt and pepper.
  5. Place the seasoned tuna steaks directly on the hot grill grates. For a medium-rare finish, grill for 1.5 to 2 minutes per side. For rare, use 1 minute per side.
  6. Use tongs to check the internal temperature if desired; 125 degrees Fahrenheit is ideal for medium-rare. You should see dark grill marks on the exterior.
  7. Remove the steaks from the grill immediately. Brush the tops lightly with the sesame ginger glaze.
  8. Let the grilled tuna steak rest on a cutting board for 5 minutes before slicing against the grain.
  9. Slice the tuna and drizzle with any remaining glaze. Garnish with toasted sesame seeds before serving.

Notes

  • For the best sear, make sure your grill is very hot before placing the tuna on it.
  • If you prefer a smoky grilled tuna flavor, use a cedar plank soaked in water for 30 minutes before grilling.
  • For a simple tuna steak marinade option, use equal parts lemon juice, olive oil, and dried herbs like thyme and oregano for 15 minutes.
