Mix. Place the garlic powder, balsamic vinegar, maple syrup, olive oil, tamari, paprika, salt, and pepper in a large bowl and whisk to combine.
Marinate. In a shallow pan, place the oyster mushrooms and drizzle them with the marinade. Let marinate for 10 minutes.
Air fry. Place the mushrooms in a single layer on an air fryer, optionally flipping once, until tender and caramelized, about 15 minutes at 350 ºF (175ºC), 7-8 minutes per side.
Garnish. Transfer to a serving dish and optionally top with chopped parsley.
Serve immediately.

Notes
When using an air fryer, it's crucial to remember that each model, with its unique power level (watts), can yield different results. To ensure you get the perfect finish every time, always check your dish halfway through the suggested cooking time. This mid-point check is a golden rule, and it's one that most air fryer manuals emphasize too. Many air fryers even come with a handy beep to remind you! By doing this, you can adjust the timing as needed and avoid any unexpected crispy surprises.
