Coat the mushrooms:
Place the mushrooms in a large bowl and pour the garlic butter mixture over them. Toss the mushrooms well so that they are evenly coated with the butter and seasonings.
Air fry the mushrooms:
Arrange the mushrooms in a single layer in the air fryer basket or tray. Avoid overcrowding to ensure they cook evenly.
Cook at 375°F (190°C) for 8-10 minutes, shaking the basket or stirring the mushrooms halfway through the cooking time to ensure they cook evenly.
Check for doneness:
The mushrooms should be golden brown and tender when done. If you prefer them a bit more crispy, you can cook them for an additional 2-3 minutes.
Serve:
Once cooked, remove the mushrooms from the air fryer and transfer them to a serving dish. Garnish with freshly chopped parsley (optional) and serve immediately.
