Begin by gently cleaning your fresh button or cremini mushrooms using a damp cloth to remove dirt. Trim the stems for uniformity.

In a large mixing bowl, combine the clean mushrooms with extra virgin olive oil, garlic powder, salt, and black pepper until evenly coated.

Set your air fryer to a temperature of 200°C (400°F) and preheat for about 5 minutes.

Place the seasoned mushrooms in a single layer in the air fryer basket. Cook for 10-12 minutes, shaking halfway through.

Check for doneness by ensuring mushrooms are golden brown and crispy; cook an additional 2-3 minutes if needed.

Remove from the air fryer, transfer to a serving platter, and garnish with freshly chopped parsley.
