Place the chicken breast between two layers of parchment paper. Use a rolling pin or meat mallet to gentle press the chicken so it's an even width throughout. Dry the chicken breasts off with paper towel.
Pour the oil onto the chicken (I do this right on the parchment) and rub all over, coating it equally. Sprinkle with a pinch of salt.
Combine the rest of the ingredients in a small bowl, shaking together. Pour onto a large rimmed plate.
Cover each of the chicken breasts well with the panko mixture, and then place onto the mesh basket of your air fryer, making sure to leave room between the breasts - they would not be touching.
Spray the tops of the chicken with cooking spray and cook 8 minutes. Gently flip and cook another 6-8 minutes until the chicken is crispy and golden and an instant read thermometer reads 165 degrees Fahrenheit inserted into the chicken
