Simple Seared Ahi Tuna Recipe – Your go-to seared ahi tuna recipe!  So simple and always delicious!


  • (2) 1 inch tuna steaks
  • kosher salt
  • ground black pepper
  • 2 teaspoons sesame seeds
  • 2 tablespoons olive oil


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


  • Paleo/Whole30: To ensure Whole30/Paleo compliance – use coconut aminos.  For a gluten-free alternative, use Tamari sauce.  Otherwise, feel free to use soy sauce.
  • How to Serve: we love these Seared Tuna Rice Bowls or these Ahi Tuna Tacos!
  • eat undercooked or raw foods at your own risk (see full blog post for discussion about sushi-grade tuna, etc)
