Hot Seafood Dip combines chopped cooked shrimp and genuine lump crab with a seasoned cream-cheese base, mozzarella, Parmesan, and fresh green onion. It bakes into a rich, scoopable appetizer with bubbling edges and a lightly golden cheese top, ready for toasted baguette, crackers, or tortilla chips.
This is a 35-minute recipe: allow 10 minutes for preparation and 20 to 25 minutes at 375°F. A brief optional broil adds color, but careful mixing and correct seafood are what preserve the best texture.
Hot Seafood Dip Ingredients
The creamy base needs 8 ounces softened cream cheese, ½ cup sour cream, exactly 2 minced garlic cloves, 1 teaspoon Old Bay or Cajun seasoning, salt and black pepper to taste, and an optional ½ teaspoon hot sauce. Soft cream cheese is essential for a smooth blend.
Fold in 1 cup chopped cooked shrimp, 1 cup drained lump crab meat, 1 cup shredded mozzarella divided between filling and topping, ½ cup grated Parmesan, and exactly 2 chopped green onions or chives, also divided. Serve with toasted baguette slices, crackers, or tortilla chips.

How to Make Cheesy Shrimp and Crab Dip
- Preheat the oven to 375°F and choose an oven-safe baking dish.
- Mix softened cream cheese, sour cream, minced garlic, seasoning, salt, pepper, and the optional hot sauce until completely smooth.
- Gently fold in chopped cooked shrimp, drained lump crab, half the mozzarella, all the Parmesan, and half the green onions or chives. Keep visible pieces of crab intact.
- Spread the mixture evenly in the baking dish and cover it with the remaining mozzarella.
- Bake for 20 to 25 minutes, until hot throughout, bubbling at the edges, and beginning to turn golden.
- For more color, broil for 1 to 2 minutes while watching constantly. Garnish with the remaining green onion and serve hot.

Soften the Cream Cheese First
Let the 8-ounce block soften enough to accept a spoon or spatula without resisting. Cold cream cheese tends to remain in small white lumps after sour cream is added, which makes the base harder to season evenly. Softening does not mean melting; it should retain its shape at room temperature.
Blend the cream cheese and ½ cup sour cream before adding seafood. Work in the garlic, measured seasoning, salt, pepper, and optional ½ teaspoon hot sauce until the color and texture are consistent. Taste the base carefully before seafood is added, remembering that Parmesan and crab contribute salinity.

Handle Shrimp and Real Lump Crab Gently
The shrimp must already be cooked; chop it into bite-size pieces so each scoop contains seafood. Drain the cup of lump crab meat thoroughly and pick through it for any shell fragments. The source recipe specifically calls for lump crab rather than imitation crab because its texture and flavor are central to the dip.
Use a folding motion once the seafood enters the bowl. Turn the mixture from the bottom over the top instead of vigorously stirring. That keeps attractive crab chunks intact and prevents the mixture from becoming uniformly shredded or pasty.
Layer the Cheeses Correctly
Only half of the 1 cup mozzarella goes into the seafood mixture, while the entire ½ cup Parmesan goes inside. Mozzarella adds creamy stretch and forms the browned top; Parmesan seasons the filling and adds savory depth without creating a heavy surface crust.
Spread the combined dip into an oven-safe dish of a size that creates a reasonably shallow, even layer. Smooth the surface, then distribute the reserved mozzarella from edge to edge. Even thickness helps the middle become hot at the same time the perimeter bubbles.
Bake, Then Broil Only if Needed
Bake at exactly 375°F for 20 to 25 minutes. The reliable signs are active bubbles near the sides, melted cheese across the top, and a center that is hot rather than merely warm. Because the shrimp is already cooked, extending the bake unnecessarily can make it firm.
If the dip is hot but the top is still pale, switch to the broiler for only 1 to 2 minutes. Stay at the oven and watch continuously; mozzarella can change from golden to burned very quickly. Remove the dish as soon as scattered golden spots appear.
Finish and Serve While Warm
Scatter the reserved green onions or chives over the hot top immediately after baking. This final addition supplies fresh color and mild onion flavor without wilting into the filling. Let the dish rest briefly so bubbling subsides, but serve it while the cheese remains soft.
Offer sturdy toasted baguette slices, crisp crackers, or tortilla chips. A broad serving spoon works for bread, while smaller scoops make it easier to load chips without breaking them. Keep the hot baking dish on a heatproof board and warn guests that its handles remain hot.
Prepare Ahead Without Overbaking
The dip may be mixed and spread in its baking dish ahead of time, then covered and refrigerated before baking. Keep the reserved garnish separate. If the dish goes into the oven cold, it may need a few additional minutes beyond the standard range; use bubbling edges and a hot center as the guide.
Do not broil a refrigerator-cold dip before it has heated through. The top would brown while the center stayed cool. Complete the normal bake first and use the 1-to-2-minute broil only as an optional finishing step.
Storage, Reheating, and Food Safety
Refrigerate leftovers in a covered container for up to 2 days, following the source recipe. Since the dish contains cooked shellfish and dairy, do not allow it to remain at room temperature throughout a long party. Put out a smaller portion and replenish it if necessary.
Reheat gently in the oven or microwave until hot. Short intervals help prevent the cheese from separating and the seafood from becoming rubbery. Stirring a reheated individual portion can restore its creamy consistency, although the broiled surface will naturally soften.
Useful Troubleshooting
A watery dip usually points to seafood that was not drained thoroughly. Pat chopped shrimp dry when needed and let lump crab drain before measuring. A lumpy base usually means the cream cheese was too cold; smooth the dairy and seasoning completely before folding in seafood.
If the finished dip tastes overly salty, the combined seasoning, cheese, and seafood may have been salted too aggressively. Add salt only to taste, and consider the salt already present in Old Bay or Cajun seasoning and Parmesan. If the crab disappears into the mixture, fold more gently next time.
Conclusion
Mix softened cream cheese, sour cream, garlic, seasoning, salt, pepper, and optional hot sauce. Fold in cooked shrimp, lump crab, half the mozzarella, Parmesan, and half the onions. Top with remaining mozzarella and bake at 375°F for 20 to 25 minutes. Optionally broil 1 to 2 minutes, garnish, and serve hot.
