Preheat Oven
Preheat your oven to 375°F (190°C).
Prepare the Base
In a large mixing bowl, combine whipped cream cheese, tartar sauce (or mayonnaise), Worcestershire sauce, hot sauce (if using), Old Bay seasoning, and lemon juice. Mix until smooth.
Add Crab Meat
Gently fold in the lump crab meat, being careful to keep the chunks intact for texture.
Incorporate Cheese
Stir in shredded Monterey Jack and mozzarella cheeses for richness and a gooey finish.
Transfer to Dish
Spoon the mixture into an oven-safe dish or skillet, spreading it evenly.
Garnish and Bake
Lightly spray the top with olive oil cooking spray and sprinkle with additional Old Bay seasoning. Bake for 20–25 minutes, until hot and bubbly, with a lightly golden top.
Serve Immediately
Garnish with fresh parsley and serve warm with toasted baguette slices, crackers, or vegetables.
