Remove steak from refrigerator and allow it to sit at room temperature for 30 minutes.
1 Steak
Meanwhile, preheat the air fryer to 350°F.
Pat the steak dry with paper towels.
Lightly brush both sides of the steak with olive oil or melted butter and season if desired.
2 teaspoon Olive Oil or Melted Butter, Seasoning of Choice
Place the steak in the basket of the preheated air fryer.
Cook the steak for a total of 6-8 minutes, depending on the size and thickness, making sure to flip the steak half way through the cooking time. A thinner steak may require only 4-6 minutes, while thicker cuts might need an additional 1-2 minutes.
Monitor the internal temperature of the steak with an instant read thermometer to ensure the inside of the steak does not overcook. (See note.)
Once the steak has reached your target internal temperature, carefully remove it from the air fryer and let it rest on a wire rack before enjoying.
