Preheat the oven to 350°F (175°C).

In a mixing bowl, combine the lump crab meat, mayonnaise, Dijon mustard, Worcestershire sauce, lemon juice, shredded cheddar cheese, parsley, Old Bay seasoning, salt, and black pepper. Mix gently to combine without breaking up the crab meat.

Transfer the crab mixture into a greased baking dish.

In a separate bowl, mix the bread crumbs with melted butter. Sprinkle the bread crumb mixture evenly over the crab mixture.

Bake in the preheated oven for 20-25 minutes or until the top is golden brown and the mixture is heated through.

Garnish with additional chopped parsley before serving.
