The secret to a great seafood cheese dip is balance. You want the seafood to be the star, not an afterthought floating in a sea of cheese. This recipe uses:
Chef's Tip: Pat your shrimp and crab meat dry with paper towels before mixing. Excess moisture is the number one reason a seafood dip turns watery instead of creamy.
This dip walks the line between a warm seafood dip you would scoop with crackers and something hearty enough to serve as a light main course over rice or in lettuce cups. Some readers even compare it to a cheesy shrimp casserole, minus the extra starch and bake time.
A few small habits make a big difference in how this dip turns out:
If you love the flavors here but want something a little more filling, this same seafood mixture also works beautifully spooned over split biscuits, echoing that classic seafood casserole with cheddar bay biscuits combination people love at seafood restaurants.
Ready to make it? Here is the full step-by-step recipe:

This baked seafood dip loads sweet crab and juicy shrimp into a bubbly, cheesy base with tender veggies, the ultimate hot crab and shrimp dip for parties and game day.
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, mayonnaise, and sour cream together until smooth and creamy.
Fold in the crab meat, chopped shrimp, 1 cup of the cheddar cheese, the parmesan cheese, red bell pepper, green onions, and garlic.
Season the mixture with Old Bay, Worcestershire sauce, hot sauce, and lemon juice, then stir until everything is evenly combined.
Spread the mixture evenly into the prepared baking dish and top with the remaining 1/2 cup of cheddar cheese.
Bake uncovered for 20 to 25 minutes, until the dip is bubbling around the edges and the cheese on top is melted and golden.
For extra color, broil for the last 1 to 2 minutes, watching closely so it does not burn.
Remove from the oven and let cool for 5 minutes, then garnish with fresh parsley and extra green onions before serving warm.
Serve this dip hot, straight from the oven, with sturdy dippers like toasted baguette slices, buttery crackers, or tortilla chips. It also pairs nicely with celery sticks or endive leaves if you want a lighter, low carb option alongside it.
For leftovers, let the dip cool completely before transferring it to an airtight container. It will keep in the refrigerator for up to 3 days, and it reheats well in the microwave or a low oven. If you are planning ahead for a party, you can fully assemble the unbaked dip a day in advance, then simply pop it in the oven when your guests arrive.
Chef's Tip: If the top browns faster than the center heats through, tent the dish loosely with foil for the last few minutes of baking so the inside catches up without burning the cheese.
However you serve it, this hot crab and shrimp dip is guaranteed to be the first thing to empty off the table.
