In a medium bowl, combine the softened cream cheese, sour cream, mayonnaise, grated Parmesan cheese, minced garlic, black pepper, and Old Bay Seasoning. Mix until well combined and smooth.
Gently fold in the chopped cooked shrimp into the cream cheese mixture.
Spoon the mixture into a small oven-safe baking dish.
Bake for 20-25 minutes, or until the dip is heated through and bubbly around the edges.
Garnish with fresh chopped parsley before serving. Serve warm with crackers, bread, or vegetable sticks.
Notes
This dip can be made ahead of time and refrigerated. Bring to room temperature for about 30 minutes before baking.
