Prepare the Chicken: Cut each chicken breast in half lengthwise to create 6 long, narrow pieces. Pound each piece to an even 1/2-inch thickness using a meat mallet. Drizzle the chicken with olive oil and toss to coat evenly.
Make the Breadcrumb Coating: In a shallow bowl, combine breadcrumbs, Parmesan, paprika, garlic powder, thyme, cayenne pepper, and salt. Mix until evenly blended.
Coat the Chicken: Dip each chicken breast into the breadcrumb mixture, pressing lightly to ensure the breadcrumbs adhere to the chicken evenly on both sides.
Preheat the Air Fryer: Preheat the air fryer to 390°F (200°C) for about 3-5 minutes.
Cook the Chicken: Coat the air fryer basket with nonstick spray and place the chicken in a single layer. Air fry at 390°F for 4 minutes on the first side, then flip the chicken and continue cooking for 2-5 more minutes, or until the internal temperature reaches 165°F and the coating is golden brown.
Serve: Let the chicken rest for a couple of minutes before serving. Enjoy with your favorite sides!
