Line the basket of your air fryer with parchment paper (this prevents sticking and makes cleanup easy). Preheat the air fryer to 350°F if your model requires preheating.
In a large mixing bowl, combine the egg, lemon juice, mayonnaise, Sriracha, parsley, green onions, Panko breadcrumbs, Worcestershire sauce, Old Bay seasoning, salt, and pepper. Stir until everything is evenly mixed into a cohesive binder. Gently fold in the drained lump crab meat, being careful not to break up the lumps too much; you want nice chunks of crab in every bite.
Using about ⅓ cup of the mixture per patty, shape into 6 crab cakes, each about 3 inches in diameter and roughly ¾-inch thick. (For best results, pack them firmly but gently so they hold together.)
Working in batches if needed (avoid overcrowding the basket for even crisping), place the patties in the prepared air fryer basket.
Air fry at 350°F for 10 minutes, flipping the patties halfway through cooking, until they are golden brown on the outside and heated through.
Serve warm with lemon wedges and tartar sauce, if desired.
