Spritz the air fryer basket with oil spray and place the frozen chicken in the basket. Spritz the chicken with oil spray.
Air fry at 400 degrees for 10 minutes, or until hot and crispy.
While the chicken is cooking, butter each piece of bread on one side. Sprinkle the butter with garlic salt.
When the chicken has finished cooking, place one slice of bread, butter side down, in the air fryer basket. Spread 1 tablespoon of marinara sauce over the bread and sprinkle with half of the parmesan and mozzarella. Place the chicken breast over the top and spread the remaining marinara over the top. Sprinkle with the remaining cheese. Sprinkle the Italian seasoning over the cheese and place the second piece of bread, butter side up, on the sandwich.
Air fry at 360 degrees for 4 minutes before carefully flipping the sandwich and cooking for 3-4 more minutes or until the bread is golden and crispy.
Serve hot.
Notes
You may use chicken patties in this recipe, but we prefer chicken breast filets. If using a chicken patty, cook for around 8 minutes. Add more sauce to your sandwich to suit your tastes.
