Prep the shrimp: Pat the cooked shrimp dry with paper towels. Chop finely so there are small pieces in every bite.
If using larger shrimp, aim for pea-sized bits to avoid stringy chunks.
Soften the base: In a medium bowl, beat the softened cream cheese until smooth and fluffy. This step keeps the dip from feeling heavy.
Build the creaminess: Add sour cream and mayonnaise. Mix until fully combined and silky with no lumps.
Layer the flavor: Stir in horseradish, hot sauce, lemon juice, Worcestershire, Old Bay, garlic powder, onion powder, salt, and pepper.
Taste and adjust heat and tang now.
Fold in the shrimp and herbs: Gently fold in the chopped shrimp, green onion, and dill or parsley. Avoid overmixing so the shrimp pieces stay intact.
Brighten it up: Add lemon zest if using. Taste again and tweak with a pinch more salt, a squeeze of lemon, or an extra dash of hot sauce as needed.
Chill: Cover and refrigerate for at least 30 minutes, ideally 1–2 hours.
The flavors meld and the texture sets.
Serve: Transfer to a serving bowl, garnish with extra green onion or dill, and serve with your favorite dippers.
