This is the easiest homemade chicken parmesan recipe you will find! It is all cooked in a single air fryer basket and beginning to end is complete in about 20 minutes!
Pound out the chicken breasts to an even thickness between two sheets of plastic wrap.
Crack the egg into a shallow bowl and add 1 tablespoon of water. Whisk with a fork until combined.
Add the Panko, Parmesan, garlic powder, onion powder, and salt to a second bowl and stir to combine.
Dip each chicken breast into the egg and then the breadcrumbs, pressing the breadcrumbs into the chicken so that they adhere.
Place chicken breasts evenly spaced in a greased air fryer basket. You will likely need to work in batches for all of the chicken to fit. Spritz chicken with oil spray.
Air fry at 380 for 10 minutes. Flip chicken over and air fry for 5 more minutes or until the chicken reaches 160 degrees internally. Check temperature as cook time will depend on the size and thickness of your chicken breasts.
Top each piece with 2 tablespoons of marinara. Sprinkle evenly with the mozzarella.
Air fry for 3 more minutes or until the chicken reaches 165 degrees.
