  • 1 tablespoon Brown Sugar
  • 2 tablespoon Honey
  • 3 tablespoon Coconut Aminos naturally Gluten free, it tastes like soy sauce and is delicious. You can sub in soy sauce if you wish.
  • 2 tablespoon Sesame Seed Oil
  • 2.5 tablespoon Furikake a Japanese spice that is absolutely delicious
  • 4 filet Tuna


  • Take the furikake, sesame seed oil, honey, brown sugar, and coconut aminos and place in a bowl. Whisk them together to form your marinade. Meanwhile, take your ahi tuna and pat it down with a paper towel to get rid of the extra liquid.
  • Take either a plastic bag (containers are fine as well) and place the ahi tuna inside. Pour the marinade in there and shake it up to make sure everything gets covered. Place in the fridge. Allow the marinade to sit for at least one hour, you can go overnight as well.
  • When you are ready to fry up your fish, take 2 tablespoons of oil (I used olive but you can use canola or any oil you wish) and let it heat up for 2 minutes. Place the tuna in the pan and let it fry. Depending on how you want to cook your ahi tuna, will determine how long you fry it on each side. For medium you want 1.5-3 minutes per side depending on the thickness of your filet. Rare would be 1-1.5 minutes per side. Well done would be 4-5 minutes per side. Once you have fried your tuna, set aside and allow it to sit for 3-5 minutes. Slice it and serve. If you wish, it is optional, top with more furikake, chives, and a squeeze of lime.
