Ingredients
  

For the tuna
  • 2 ahi tuna steaks sushi/sashimi grade, #1 or #2 grade recommended
  • 1 tsp sea salt
  • 1 tsp ground black pepper
  • 2 tbsps sesame seeds white or mixed
  • 1 tbsp high-heat cooking oil such as avocado or vegetable oil
For the marinade (optional)
  • 2 tbsps soy sauce
  • 1 tsp sesame oil
  • 1 tbsp rice vinegar
For serving
  • Jasmine rice cooked
  • Steamed vegetables e.g., broccoli, carrots, bell peppers
  • Sesame seeds for garnish
  • Green onions sliced, for garnish
  • Spicy mayo optional

Equipment

  • Grill, grill pan, or cast-iron skillet
  • Meat thermometer
  • Tongs or spatula
  • Paper towels
  • Knife and cutting board
  • Small bowl (for marinade)
  • Sous vide machine (optional, for precise temperature control)

Method
 

  1. Prepare the Ahi Tuna
    Pat the ahi tuna steaks dry with a paper towel to remove excess moisture — this step is essential for achieving a proper sear. If using a marinade, soak the tuna in the soy sauce, sesame oil, and rice vinegar mixture for 30 minutes to 1 hour before cooking. Do not over-marinate.
  2. Season the Tuna
    Season both sides of the tuna steaks generously with sea salt and black pepper. Coat evenly with sesame seeds, pressing gently so they adhere to the surface, creating a crunchy crust.
  3. Preheat the Grill or Pan
    Preheat your grill, grill pan, or cast-iron skillet over high heat. Oil the grates or pan surface to prevent sticking. The cooking surface must be very hot before the tuna touches it.
  4. Sear the Tuna
    Place the tuna steaks on the hot grill or pan. Sear for approximately 1 minute per side — the exterior should be golden and crusted while the center remains rare and tender. Use tongs or a spatula to flip gently. Use a meat thermometer to verify doneness if needed.
  5. Rest, Slice, and Serve
    Remove the tuna from the heat and let it rest for 1–2 minutes. Slice against the grain into thick pieces. Serve over jasmine rice surrounded by steamed vegetables. Garnish with sesame seeds and green onions. Add spicy mayo on the side if desired.

Notes

  • Use sushi-grade tuna: Always choose sushi or sashimi grade (#1 or #2) ahi tuna — it's essential for safety and the best flavor when served rare.
  • Don't overcook: Sear for no more than 1 minute per side over very high heat. The center should stay rare and pink. Overcooking makes it dry and tough.
  • Pat dry before searing: Removing excess moisture with a paper towel is the key step to getting a proper golden crust.
  • Storage: Keep leftovers in a sealed container in the fridge at 40°F or below and consume within 1–2 days.

Get your pan smoking hot before the tuna goes in — a properly preheated surface is what creates that golden crust while keeping the center perfectly rare. Don't move the fish; let it sear undisturbed for a full minute before flipping.
