First, you’ll want to make sure your skillet is hot hot hot. We’re talking set to medium / high with enough time to fully heat up.

You’ll know your skillet is good to go when the olive oil is fragrant. Place 1 tuna steak in the skillet and adhere to the following cook times depending on how well done you like your seared ahi tuna:

  • Rare: 30 seconds per side
  • Medium rare: 1 minute per side
  • Well done: 2 minutes per side

Is seared ahi tuna safe?

Yes, seared ahi tuna is safe to eat. If you feel uncomfortable eating a rare ahi tuna steak, feel free to cook it until it is cooked through the middle.

Also, if your ahi tuna smells funny or off we suggest not eating it!

Fresh or Frozen Ahi Tuna

You can use fresh ahi tuna or frozen ahi tuna.

If you are using frozen ahi tuna, remove the frozen fish from the freezer the day before you plan to eat it and place it in the refrigerator to thaw.

Store your ahi tuna in a airtight container for up to 5 days.
