Start with fresh, sushi-grade ahi tuna steaks. Pat them dry with a paper towel.

Sprinkle salt and pepper generously on both sides of the steaks.

Place your skillet over medium-high heat and add the sesame oil.

Once the oil is shimmering, carefully place the tuna steaks in the skillet.

Sear for about 1-2 minutes without moving them.

Using a spatula, gently flip the steaks and sear for another 1-2 minutes.

If using a meat thermometer, check for an internal temperature of 125°F for medium-rare.

Once cooked to your liking, remove the tuna from the skillet and let it rest for a minute.

Using a sharp knife, slice the tuna into thin strips.
