Lay chicken breasts out on a clean chopping board.
Smother the chicken breasts in lemon juice and rind from your large lemon and season with sea salt.
Add ground black pepper and garlic powder.
Place your chicken breasts into the air fryer basket. Cut your lemon slices and find a place on top of the breasts and to the side of them. Air fry for 15 minutes at 180c/360f.
Check the chicken and then cook for a further 3-5 minutes if they are still pink in the middle. Slice the chicken breasts and serve.
