  • dutch oven or cast iron skillet
  • mixing bowl
  • whisk
  • baking dish


  • 1-1.5 lbs Ahi Tuna Steaks This is usually about 2 large tuna steaks

Ahi Tuna Marinade

  • 3 Tablespoons Soy Sauce
  • 1 Tablespoon Everything But The Bagel Seasoning
  • 1 Tablespoon Sesame Oil
  • 1/2 Tsp Salt
  • 1/2 Tsp Black Pepper
  • 1 Tablespoon Mikes Hot Honey or regular honey
  • Juice of 1 lemon
  • 3 Tablespoons coconut oil
  • Black Sesame seeds for garnish


  • In a small bowl combine soy sauce, sesame oil, everything but the bagel seasoning, salt, pepper, lemon juice, and hot honey. Whisk to combine.
  • In a shallow dish place your tuna steaks and pour marinade over them. Cover and let sit in the refridgerator for 3-6 hours. The longer the better!
  • Take out your tuna and over high heat get 3 tablesoons of coconut oil screaming hot in a cast iron pan. I use a dutch oven because the sides are tall and there is less splatter.
  • When the pan is very hot, lay one tuna steak down in the oil. Cook for 45 seconds -1 Minute depending on the level of rareness you like.
  • Flip to the other side and cook for an additional 45 seconds to 1 minute.
  • Remove from pan and lay on a cutting board to rest for 5 minutes. Repeat with 2nd tuna steak.
  • With a serrated knife, cut slices against the grain of the tuna.
  • Top with sesame seeds and sliced avocado!


This is also delicious with siracha mayo and a cabbage slaw.
