Preheat your oven to 350°F (175°C).
In a mixing bowl, combine the softened cream cheese, mayonnaise, grated Parmesan cheese, sour cream, shredded mozzarella cheese, minced garlic, lemon juice, Worcestershire sauce, and optional hot sauce. Mix until well combined.
Gently fold in the drained lump crab meat until evenly distributed throughout the mixture.
Season the mixture with salt and pepper to taste, adjusting as needed.
Transfer the crab mixture into an oven-safe baking dish, spreading it out evenly.
Bake in the preheated oven for about 20-25 minutes, or until the dip is heated through and bubbly around the edges.
Once done, remove the dip from the oven and let it cool for a few minutes.
Garnish with chopped fresh parsley if desired.
Serve the "Irresistible Crab Dip" warm with your favorite crackers, bread, or veggies for dipping.
