Preheat oven to 350°F (175°C). Lightly grease an 8x8 inch baking dish.
In a medium bowl, gently combine the crab meat, mayonnaise, Dijon mustard, Worcestershire sauce, Old Bay Seasoning, salt, and pepper. Be careful not to break up the crab meat too much.
Gently fold in the beaten egg, crushed butter crackers, chopped parsley, and lemon juice.
Transfer the crab mixture to the prepared baking dish and spread evenly.
Bake for 20-25 minutes, or until heated through and lightly golden on top.
Let stand for a few minutes before serving.
Notes
Serve hot as an appetizer or as a main course with a side salad.
