Start by gathering all your ingredients. Drain the canned crab meat thoroughly and set it aside. Make sure your cream cheese is at room temperature.
In your mixing bowl, combine the room temperature cream cheese, mayonnaise, and sour cream. Use a spatula or whisk to mix until smooth and creamy.
Add the sliced green onion, fresh lemon juice, Cajun seasoning, Worcestershire sauce, and hot sauce. Stir until everything is well incorporated.
Gently fold in the well-drained lump crab meat, being careful not to break it up too much.
Transfer your Cajun Crab Dip to a serving dish, cover it, and chill in the refrigerator for at least 30 minutes before serving.
