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.

There is a reason this Cheesy Shrimp and Crab Bake Dip shows up at every party I host. It comes out of the oven golden, bubbling, and loaded with sweet crab and tender shrimp folded into a rich, garlicky cream cheese base. If you love seafood recipes appetizers that feel a little fancy but come together with almost no fuss, this is the one to bookmark. It sits comfortably alongside other favorites like shrimp mold dip or a classic cream cheese seafood dip, but the combination of both shrimp and crab together gives it a deeper, more satisfying flavor.
What I love most about this cheesy shrimp and crab bake dip is how forgiving it is. You can use fresh, frozen, or even canned seafood and it still tastes like something from a coastal seafood shack. It is one of those seafood apps that disappears from the table before you even get a chance to grab a second cracker.
Before we get cooking, the right tools and ingredients make a real difference here. A sturdy small baking dish helps the dip heat evenly without scorching the edges, and freshly grated parmesan melts so much better than the pre-shredded bagged kind. These are the products that genuinely help this recipe shine:
The magic of a great seafood dip recipe comes down to balance. You want the cream cheese rich enough to hold everything together, but not so heavy that it drowns out the shrimp and crab. A splash of lemon juice and a little hot sauce cut through the richness, while Old Bay seasoning brings that briny, slightly peppery flavor that says seafood the moment it hits your nose.
Chef's Tip: Pat your shrimp and crab meat dry with a paper towel before mixing them in. Excess moisture is the number one reason seafood dips turn watery instead of creamy.
If you are comparing this to other shrimp and crab dip with cream cheese recipes, the main differences here are the extra layer of parmesan for a deeper savory note, and baking it instead of serving cold. Both choices give the final dip a richer, more restaurant style texture.

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 the 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 and fluffy.
Fold in the crab meat, chopped shrimp, cheddar cheese, parmesan cheese, minced garlic, and green onions.
Season with Worcestershire sauce, Old Bay seasoning, lemon juice, hot sauce, salt, and pepper, then stir gently until evenly distributed.
Spread the mixture evenly into the prepared baking dish and smooth the top with a spatula.
Sprinkle a little extra cheddar cheese and a dash of Old Bay over the top.
Bake for 20 to 25 minutes, until the dip is bubbling around the edges and golden on top.
Remove from the oven and let it rest for 5 minutes before garnishing with fresh green onions.
Serve warm with crackers, toasted baguette slices, or crunchy vegetables.
This dip is best served warm, straight from the oven, with sturdy crackers, toasted baguette slices, or crisp vegetables like celery and bell pepper strips for dipping. It also works beautifully spooned over a baked potato or stuffed into mini phyllo cups for a more elegant presentation at a party.
If you have leftovers, let the dip cool completely before transferring it to an airtight container. It keeps well in the refrigerator for up to three days. When you are ready to reheat, the oven is your best friend here, since a low and slow reheat in a 350 degree F oven brings back that same creamy texture without breaking the dairy. The microwave works in a pinch, but reheat it in short bursts and stir often.
Whether you are building out a full spread of seafood recipes appetizers for a holiday table or just want one standout dish for a casual get together, this cheesy shrimp and crab bake dip earns its spot every single time. It has all the comfort of a classic seafood cheese dip with just enough texture from the shrimp and crab to make it feel special. Make it once and I promise it becomes a regular request.
