Spray your baking dish with cooking spray, and prepare your pasta as directed on the box
Drain the pasta, add it to a large bowl, and add the marinara sauce, shredded chicken, 1/2 of the shredded mozzarella, and 1/2 of the grated parmesan cheese; add the Italian seasoning.
Transfer back to the saucepan, and simmer for a couple of minutes; fold in the rest of the cheese.
Transfer the ingredient to the baking dish, and spread them into an even layer. Add the panko, melted butter, salt, black pepper, and garlic powder in a small bowl, and mix well.
Sprinkle the panko on top of the casserole. Set into the air fryer and set cook time for 6 to 10 minutes, at 330 degrees F; using the air fryer setting, cook until the top is golden brown. Cover it tightly with foil if you find that the top is getting too browned.
Serve with additional marinara or pasta sauce, extra Parmesan cheese, and freshly diced herbs.
