If you have large chicken breast fillets then slice them in half lengthways to make chicken fillets which are not too thick. You can buy chicken cutlets, but I find these harder to source in UK supermarkets these days.
Crack the egg and whisk in a bowl. Add your herbs to this whisked egg.
Add your breadcrumbs to a separate bowl. Add salt and pepper to the breadcrumbs.
Pre-heat your air fryer to 200C.
Prepare your chicken breasts by removing any fat or skin.
Dip the chicken breasts into the egg, then add to the breadcrumb bowl. Turn over several times to ensure even coverage. You can repeat this step if you want a large amount of breading.
Spray the air fryer basket with spray oil IF you use this. I typically skip this step now.
Add the breaded chicken breasts to your air fryer basket in a single layer.
Air fry at 200C (390F approx) for 6 minutes.
Turn over to ensure even cooking and to prevent sticking.
Air fry for a further 6 minutes at 200C (390F approx).
Check that the chicken is at the safe internal cooking temperature for chicken (75C/165F approx) before serving.
If you like you can rest the chicken breast for 5 minutes before slicing and serving. Alternatively you can serve up the whole chicken breast alongside the rest of your dinner.
