The cooking time for chicken breast in an air fryer varies depending on the size and thickness of the chicken breasts, as well as the temperature used. Here are general guidelines from multiple sources:

• Small breasts (5 to 7 ounces): about 7 to 10 minutes at 375°F to 400°F
• Medium breasts (8 to 10 ounces): about 10 to 12 minutes at 375°F to 400°F
• Large breasts (11 ounces or more): about 13 to 18 minutes at 370°F to 400°F

More detailed breakdowns include:

• 6 to 7-ounce breasts: 10 to 11 minutes total at 375°F, flipping halfway
• 8 to 9-ounce breasts: 11 to 14 minutes total, flipping halfway
• 10-ounce or larger breasts: 13 to 18 minutes total, flipping halfway

Cooking is typically done at 375°F to 400°F (190°C to 204°C). It is recommended to flip the chicken halfway through cooking for even results. Using an instant-read thermometer to check that the internal temperature reaches 165°F (74°C) ensures the chicken is fully cooked and safe to eat. Resting the chicken for 5 minutes after cooking helps retain juiciness. Example method: Cook chicken breasts at 375°F for 7 minutes, flip, then cook for an additional 3 to 7 minutes depending on size, until the internal temperature reaches 165°F

. In summary, expect to cook chicken breasts in an air fryer for about 10 to 18 minutes total, adjusting time based on size and thickness, at around 375°F to 400°F, flipping halfway and checking internal temperature for doneness.
