Preheat the air fryer to 360°F for 5 minutes.
Pulse the turkey in a food processor for 10 seconds to finely chop; set aside. Pulse the fried onion straws for 15 seconds.
In a large bowl, combine turkey, stuffing, mashed potatoes, Parmesan, garlic, shallot, sage, and rosemary. Shape into patties.
Whisk eggs with ½ cup water in one bowl. Combine panko and ground onion straws in another.
Dip patties in egg, then panko, pressing the crumbs to adhere.
Place in a single layer in the basket and spritz with cooking spray. Air fry 6 minutes, flip, spritz again, and air fry 6 more minutes.
Blend cranberry sauce, sour cream, horseradish, pepper, and jalapeño for 15 seconds.
Serve croquettes hot with the cranberry dip.
