Preheat the oven. Set to 375°F (190°C). Lightly grease a small baking dish or oven-safe skillet.
Prep the lobster. If using cooked tails or claws, chop into bite-size pieces. If the lobster is cold, pat it dry.
Too much moisture can make the dip watery.
Sauté for extra flavor (optional). In a small skillet, melt the butter over medium heat. Add garlic and cook 30 seconds. Stir in the lobster for 1 minute to warm and perfume with garlic.
Remove from heat and cool slightly.
Mix the creamy base. In a bowl, beat cream cheese until smooth. Mix in sour cream, mayonnaise, lemon zest, 1 teaspoon lemon juice, Old Bay, paprika, Worcestershire (if using), and a few dashes of hot sauce. Add a pinch of salt and pepper.
Add cheese and herbs. Stir in mozzarella, half of the Parmesan, and the green onions or chives.
Fold in the lobster. Gently mix in the lobster so the pieces stay chunky.
Taste and adjust seasoning. Add more lemon or Old Bay if needed.
Transfer and top. Spread the mixture evenly in the baking dish. Sprinkle the remaining Parmesan over the top for a golden crust.
Bake. Bake for 18–22 minutes, until the edges bubble and the top is lightly browned.
For extra color, broil for 1–2 minutes, watching closely.
Rest and serve. Let it sit 5 minutes so it sets slightly. Finish with a squeeze of lemon and extra chives. Serve hot with toasted baguette slices, crackers, or veggies.
