Learn how to quickly sear sushi grade yellowfin tuna to achieve a warm, flavorful crust and a cool, rare center. This Asian tuna recipe is a healthy dinner ready in minutes.

Ingredients

Scale
  • 2 (6 ounce) sushi grade ahi tuna steaks
  • 2 tablespoons sesame oil
  • 1 tablespoon soy sauce or tamari
  • 1 teaspoon grated fresh ginger
  • 1 clove garlic, minced
  • 1/4 cup black and white sesame seeds, mixed
  • Pinch of sea salt

Instructions

  1. Remove the tuna steaks from the refrigerator 15 minutes before cooking to allow them to come closer to room temperature. Pat them completely dry with paper towels.
  2. In a small bowl, whisk together the sesame oil, soy sauce, ginger, and minced garlic. Brush this mixture evenly over all sides of the tuna steaks.
  3. Place the mixed sesame seeds on a shallow plate. Gently press each side of the tuna steaks into the seeds until they are fully coated.
  4. Heat a heavy-bottomed skillet, such as cast iron, over high heat until it is very hot. Add a small amount of high smoke point oil if your pan is not non-stick, though the oil brushed on the tuna should suffice.
  5. Carefully place the coated tuna steaks in the hot skillet. Sear for 60 to 90 seconds per side for a rare center. Adjust time slightly for your preferred doneness, but avoid overcooking.
  6. Remove the tuna from the pan immediately. Sprinkle lightly with sea salt.
  7. Let the seared ahi tuna rest on a cutting board for 3 minutes before slicing against the grain into half-inch thick pieces. Serve immediately.

Notes

  • For the best sear, make sure your skillet is smoking hot before the tuna touches the pan.
  • If you prefer a slightly more cooked center, sear for 2 minutes per side.
  • Serve this gourmet tuna with a side of wasabi or a light soy dipping sauce.
