Set temperature on Air Fryer to 360 degrees Fahrenheit. Preheat 3 minutes.

Cut chicken breasts in half, lengthwise and trim.

Pound the chicken breasts into thinner pieces that are the same thickness.

In a medium bowl mix together the breadcrumbs and parmesan cheese.

In another bowl whisk the eggs together.

Dip each piece of chicken in egg and then dredge in the breadcrumb mixture. Repeat with remaining pieces of chicken.

Place chicken breasts in single layer inside of air fryer basket. If you are using a smaller air fryer you will need to cook in batches.

Add chicken breasts to preheated Air Fryer and cook for 6 minutes. Flip the chicken breasts over and top with marinara sauce and mozzarella cheese. Air fry for an addition 3-4 minutes or until chicken reaches an internal temperature of 165 degrees Fahrenheit.

Set aside and keep warm, repeat with remaining 2 pieces.
