How Long to Cook Chicken Breast in an Air Fryer at 400°F

At 400°F / 200°C, a boneless chicken breast about 2 cm thick takes 14-18 minutes in the air fryer, flipped halfway, until the thickest part reaches 74°C / 165°F.
Quick answer
- 1Pound the breast to an even thickness of about 2 cm and pat it dry.
- 2Oil and season it, then preheat the air fryer to 400°F / 200°C for 3 minutes.
- 3Cook 14-18 minutes, flipping halfway.
- 4Pull it when a probe in the thickest part reads 74°C / 165°F, then rest 5 minutes.
Why 400°F changes the time
400°F / 200°C is hotter than the 375°F / 190°C used on the full chicken breast recipe, so the same breast finishes a few minutes sooner. The safe endpoint does not change.
The USDA FSIS safe-temperature chart lists 74°C / 165°F for chicken. A thicker end still under that number is not done, even if the timer has finished.
Thickness matters more than the clock
A thin breast can be done at 14 minutes. A very thick one may need the full 18, or a little longer if you did not pound it even. Check at 14 minutes the first time.
The full method, with a rub and the 375°F version, is on the chicken breast recipe. Use this page when the basket is already set to 400°F.
