Add the corn meal, lemon zest, thyme, garlic powder, paprika, salt and pepper to a large, shallow bowl. Mix to blend evenly and set aside.
Add the flour to a second large, shallow bowl, and the egg to a third.
Sprinkle the chicken breasts lightly with salt and pepper, and one at a time, coat them with the flour lightly and evenly. Then dip them into the egg, being sure they’re well coated. Now place each breast on top of the corn meal mixture and gently press down so that it adheres to it, and do the same thing on the other side, and edges.
Remove the basket from the pot of the air fryer, and line the pot with foil. Return the basket and spray the bottom of it with the olive oil. Place the coated chicken breasts in the basket and then spray the top surface with the olive oil.
For the GoWISE USA Air Fryer, use the Preset Chicken setting for 20 minutes at 400° F.
Let the air fryer cool down and wait for the indicator that it’s ready to open.
