  5. Garnish and Serve:
    • Once cooked, remove the sautéed mushrooms and onions from the air fryer basket.
    • Garnish with chopped fresh parsley or thyme, if desired, for a pop of color and freshness.
    • Serve the air-fried sautéed mushrooms and onions as a delicious side dish alongside grilled meats, pasta, rice, or as a topping for burgers or sandwiches.
