Prepare your baking dish by spraying it with cooking spray or olive oil.
In a large bowl, combine softened cream cheese, lemon juice, diced onion, chopped green onions, Worcestershire sauce, mayonnaise, grated parmesan cheese, and black pepper. Stir until well combined.
Gently fold in the lump crab meat until it's evenly distributed throughout the cheese mixture. Be careful not to break up the crab too much.
Transfer the crab dip mixture into the prepared baking dish. Place the dish into your air fryer basket or on the tray.
Air fry at 300°F (150°C) for 20 minutes. Carefully stir the dip.
Continue air frying at 300°F (150°C) for another 10 minutes. Stir the dip again.
Increase the heat to 340°F (170°C) and air fry for an additional 5-10 minutes, or until the top is golden brown and bubbly.
Garnish with minced parsley. Let the dip cool for at least 10 minutes before serving. Enjoy with your favorite chips, crackers, bread, or vegetables!
