Preheat your air fryer to 400°F (200°C) for 5 minutes.

Create a breading station using shallow dishes for milk, flour with seasoning, ranch dressing, and panko with ranch mix.

Dip each mushroom cap in milk, then roll in the flour mixture.

Coat the mushrooms in ranch dressing thoroughly.

Roll the mushrooms in the panko bread crumb mixture, pressing gently to adhere.

Place the mushrooms in the air fryer basket in a single layer and spray with nonstick cooking spray.

Air-fry the mushrooms for about 7 minutes until golden brown. Check for doneness and adjust cooking time as needed.

Let them cool slightly before serving with your favorite dipping sauce.
