Your go-to seared ahi tuna recipe!  So simple and always delicious!



  • (2) 1 inch tuna steaks
  • salt
  • pepper
  • 2 Teaspoons sesame seeds
  • 2 Tablespoons olive oil


  1. Place tuna steaks on plate.
  2. Sprinkle each side with salt, pepper and 1 teaspoon of sesame seeds per side.
  3. Pat seasoning into each side to make sure they stick.
  4. Take large cast iron skillet and add oil.
  5. Bring to medium-high heat.
  6. When oil just starts to smoke, place tuna steaks in skillet.
  7. Cook for 30-45 seconds per side (or up to 1 minute if you just barely want it rare in the middle).
  8. Remove and let rest on clean plate for 5 minutes.
  9. Serve immediately with sauce of choice (see notes below).


  • To ensure Whole30/Paleo compliance – use coconut aminos.  For a gluten-free alternative, use Tamari sauce.  Otherwise, feel free to use soy sauce.
  • eat undercooked or raw foods at your own risk
