Prep the shrimp: If using raw shrimp, poach in lightly salted simmering water 1–2 minutes until just pink. Drain and chill.
Pat dry well. Chop into small, bite-size pieces.
Soften the base: In a medium bowl, beat softened cream cheese with a spoon or hand mixer until smooth and fluffy. This prevents lumps and makes the dip extra creamy.
Build the flavor: Mix in sour cream, lemon zest and juice, Worcestershire, hot sauce, Old Bay, and garlic.
Stir until fully combined and silky.
Fold in the mix-ins: Add chopped shrimp, green onions, herbs, and any optional celery, red pepper, or capers. Fold gently so the shrimp stay tender.
Season to taste: Add a pinch of salt and a few grinds of black pepper. Taste and adjust lemon, heat, and salt as needed.
Chill to set: Cover and refrigerate for at least 30–60 minutes.
Chilling lets the flavors bloom and the texture firm up for easier scooping.
Serve: Transfer to a shallow bowl, garnish with extra herbs and a sprinkle of Old Bay or paprika. Serve cold with crunchy dippers.
