Clean the mushrooms under cold running water and pat dry. Trim the stems for an even finish.

Set up a dredging station with flour, beaten eggs, and a mixture of panko breadcrumbs, parmesan, and ranch seasoning.

Dredge each mushroom in flour, then dip in eggs, and finally coat with the breadcrumb mixture.

Preheat air fryer to 400°F (200°C) for 5 minutes. Arrange mushrooms in a single layer in the basket.

Air fry at 400°F for 10-12 minutes, shaking halfway through, until golden brown.

Remove from air fryer, let cool, and garnish with parsley. Serve as desired.
