Get your boneless, skinless pork chops ready. Slice them into ½-inch filets. If you bought frozen ones, thaw them overnight and let them come to room temperature for at least 30 minutes before working with them. Then pat them dry with a kitchen towel. Optionally, you can brine them overnight.
Next, lightly season both sides of your pork chops with salt and pepper.
Prepare your breading station: In a shallow container, add the cornstarch. In a medium bowl, prepare the egg wash by beating an egg until smooth. In a separate shallow container, place the Panko-style breadcrumbs.
Preheat your air fryer to 400°F (204°C). If your air fryer has a capacity of 4 quarts or smaller, please see the note for more info.
While preheating, bread your lightly seasoned pork chops. Begin by dredging them with cornstarch. Then dip them into the beaten eggs, allowing any excess to drip off. Finally, coat the pork chops in the Panko breadcrumbs, pressing lightly to ensure the breadcrumbs adhere to the meat. Repeat this process for all the pork chops.
Air fry pork Tonkatsu for 10-12 minutes, flipping halfway through. Begin by carefully adding the breaded chops into the air fryer basket. Then, spray them generously with cooking oil, ensuring all areas are covered. Air fry them for 5-6 minutes, then flip the chops and spray any remaining dry areas with cooking oil spray. Cook for another 5-6 minutes. Continue air frying until the tonkatsu turns golden brown and crispy, or until you've reached your desired level of doneness.
Prepare the tonkatsu sauce by mixing ketchup, Worcestershire sauce, soy sauce, mirin, and rice vinegar. Alternatively, you can also purchase a ready-made sauce from your favorite Asian supermarket.
Allow your air fried tonkatsu to rest for 3-5 minutes. To maintain the crispiness of the crust, it's best to place them on a cooling rack.
Serve the air fryer pork tonkatsu hot with tonkatsu sauce on the side for dipping. Serve alongside shredded cabbage and cooked rice for a complete meal. Enjoy!
