Cooking Time & Fish Temperature

I love making recipes such as this Keto Sesame Ginger Ahi Tuna Steaks with ‘Potatoes’ because it’s so quick and easy to make! Depending on your preference, I’ve provided cooking times for rare, medium-rare, and medium for your ahi tuna.

    • RARE: For rare ahi tuna, you simply need to cook in a skillet over medium-high heat for 1.5-2 minutes per side.
      • *Recommended temperature, as the ahi tuna will be the most moist. 
    • MEDIUM-RARE: For medium-rare ahi tuna, you can sear each side for about 2.5 minutes.
    • MEDIUM: For medium ahi tuna, you’ll be searing each side closer to 3 minutes.

Overall, you’ll want your ahi tuna to at least reach a temperature of 115 degrees F, 46 degrees C. I’d recommend checking your ahi tuna with a thermometer before serving!
