Ingredients

  • 500g fresh tuna belly (skin on, boneless)
  • 2 tablespoons soy sauce (preferably low sodium)
  • 1 tablespoon olive oil
  • 1 tablespoon brown sugar
  • 1 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon black pepper (freshly ground)
  • 1/2 teaspoon sea salt
  • Wood chips for smoking (preferably alder or applewood)
  • Lemon wedges (for serving)

Equipment

  • Smoker or charcoal grill with smoking lid
  • Thermometer (preferably digital instant-read)
  • Mixing bowl
  • Brush (for oil and marinade application)
  • Wire rack or grill grate
  • Aluminum foil (optional, for indirect heat setup)
  • Sharp knife (for trimming and slicing)

Instructions

  1. Prepare the marinade: In a mixing bowl, combine soy sauce, olive oil, brown sugar, smoked paprika, garlic powder, black pepper, and sea salt. Whisk until sugar is dissolved and the mixture is well blended.
  2. Marinate the tuna belly: Place the tuna belly in the bowl with the marinade, making sure it’s fully coated. Cover and refrigerate for at least 1 hour, but preferably 2-3 hours for deeper flavor infusion.
  3. Preheat your smoker or grill: Set up your smoker or grill for indirect heat at a steady temperature of about 225°F (107°C). Add your chosen wood chips to generate smoke.
  4. Prepare the tuna for smoking: Remove the tuna belly from the marinade and pat it dry gently with paper towels. This helps develop a better smoke ring and texture. Brush lightly with olive oil.
  5. Smoke the tuna belly: Place the tuna on a wire rack or directly on the grill grate away from direct heat. Insert a thermometer to monitor the internal temperature. Smoke for approximately 45-60 minutes, or until the internal temperature reaches 125°F (52°C) for medium-rare. Cooking longer will yield a more well-done texture but may dry out the fish.
  6. Rest the fish: Once smoked, remove the tuna belly from the smoker and let it rest for 5-10 minutes. This allows the juices to redistribute and the flavors to settle.
  7. Slice and serve: Slice the smoked tuna belly thinly against the grain. Serve with fresh lemon wedges to brighten the rich flavors.

Tips & Variations

“For best results, use fresh, sashimi-grade tuna belly. The quality of the fish makes all the difference!”

  • Feel free to experiment with different wood chips like cherry or hickory for unique smoke flavors.
  • If you prefer a spicy kick, add a pinch of cayenne pepper or chili flakes to the marinade.
  • Try adding a splash of sake or mirin to the marinade for a subtle sweetness and depth.
  • For a quicker option, you can cold smoke the tuna belly, but be sure to follow safe food handling practices.
  • If you don’t have a smoker, use a grill with a smoking box or create a foil pouch with wood chips to infuse smoke.
