This recipe leans on a handful of simple, reliable ingredients that work together beautifully.
This dip sits comfortably alongside other favorites like shrimp mold dip or any classic shrimp and crab dip with cream cheese, but baking it gives you a warm, melty texture that cold seafood dips simply cannot match.
Chef's Tip: Pat your shrimp and crab meat as dry as possible before mixing. Excess moisture is the number one reason seafood dips turn watery instead of creamy.
The process is refreshingly simple, which is part of why this recipe has become one of my most requested seafood appetizers.
Start by beating your softened cream cheese until it is silky smooth. This step matters more than people expect. Cold, lumpy cream cheese will leave you with a grainy dip, so give it a few extra minutes if needed. From there, you simply fold in your mayonnaise, sour cream, seafood, and seasonings, then top with cheese and bake until bubbly.
This dip is incredibly forgiving, which makes it a great recipe for both beginner cooks and seasoned hosts who want something reliable for parties, game days, or holiday spreads.

This Cheesy Shrimp and Crab Bake Dip is a warm, bubbling blend of cream cheese, sweet crab, and tender shrimp baked until golden. It is the easiest seafood appetizer you will make all year.
Preheat your oven to 375 degrees F (190 degrees C) and lightly grease a small baking dish or cast iron skillet.
In a large bowl, beat the softened cream cheese until smooth and creamy.
Mix in the mayonnaise and sour cream until fully combined.
Fold in the crab meat, chopped shrimp, minced garlic, lemon juice, Worcestershire sauce, and Old Bay seasoning.
Stir in half of the mozzarella, half of the parmesan, and the sliced green onions. Season with salt and pepper to taste.
Spread the mixture evenly into the prepared baking dish.
Sprinkle the remaining mozzarella and parmesan evenly over the top, then dust lightly with extra Old Bay.
Bake for 20 to 25 minutes, until the dip is hot and bubbling and the cheese on top is melted and golden in spots.
Remove from the oven and let rest for 5 minutes before garnishing with fresh parsley and extra green onions.
Serve warm with crackers, toasted baguette slices, or fresh vegetables for dipping.
This Cheesy Shrimp and Crab Bake Dip is wonderfully versatile when it comes to serving. Here are a few of my favorite pairings:
If you want to switch things up, try adding a pinch of cayenne or a few dashes of hot sauce for heat, or stir in some chopped artichoke hearts for a fun twist on a classic seafood cheese dip. You can also broil the top for the last 1 to 2 minutes of cooking if you want extra color and a slightly crisped, bubbly crust.
Chef's Tip: If you are serving this at a party, bake it in a small cast iron skillet. It holds heat beautifully and keeps the dip warm and inviting for much longer than a standard baking dish.
Like most great seafood apps, this dip is best fresh from the oven, but leftovers are still delicious. Let the dip cool completely, then transfer it to an airtight container and refrigerate for up to 3 days. To reheat, warm it gently in the oven at 350 degrees F until heated through, or microwave it in short bursts, stirring in between, to keep the texture smooth and creamy rather than separated.
Whether you are building out a full spread of seafood recipes appetizers or just want one standout dish for your next gathering, this dip earns its place at the center of the table every single time.
