Preheat the air fryer to 375°F (190°C).
In a large bowl, combine crab meat, mayo, egg, Dijon mustard, Old Bay, lemon juice, parsley, and breadcrumbs. Mix gently to avoid breaking the crab lumps.
Shape the mixture into patties about half an inch thick.
Spray the air fryer basket with cooking spray.
Arrange the patties in a single layer, leaving space between each.
Cook for 10 to 12 minutes, flipping once halfway through, until golden and crisp.
Serve immediately with tartar sauce, remoulade, or fresh lemon wedges.
