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


  • (2) 1 inch raw ahi tuna steaks
  • kosher salt
  • ground black pepper
  • 2 teaspoons white sesame seeds
  • 2 tablespoons extra virgin olive oil (or avocado oil)


  1. Pat tuna steaks dry with a clean paper towel.
  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. Bring a large cast-iron skillet to a medium-high heat and add oil.
  5. When oil just starts to smoke, place tuna steaks in skillet.
  6. Cook for 30-45 seconds per side (or up to 1 minute if you just barely want it rare in the middle) – this will create a nice crust on the outside.
  7. Remove and let rest on clean plate for 5 minutes.
  8. Slice against the grain & serve immediately with sauce of choice (see notes below).


  • Paleo/Whole30: serve with coconut aminos. Otherwise, feel free to use soy sauce.
  • Gluten-Free: serve with tamari sauce!
  • How to Serve: we love these Seared Tuna Rice Bowls or these Ahi Tuna Tacos!
  • Storage: it is best to consume this dish immediately – if you have leftovers store in an airtight container in the refrigerator and consume within 24 hours. 
  • eat undercooked or raw foods at your own risk (see full blog post above for discussion about sushi-grade tuna, etc)
