Creamy Shrimp and Crab Spinach Dip

A rich, bubbling hot seafood dip packed with sweet crab, tender shrimp, and fresh spinach in a velvety, three-cheese base.

Why This Recipe Works:

• Squeezing the spinach dry prevents excess water from diluting the rich cheese base.
• A touch of cornstarch stabilizes the dairy emulsion, keeping it smooth even under the broiler.
• Folding the delicate lump crab meat in last preserves those sweet, luxurious pockets of seafood texture.

I still remember the humid July evening three years ago when I tried to serve a seafood dip at my sister's backyard housewarming, only to watch the entire mixture separate into a greasy, watery swamp on the picnic table.

My forearms actually ached from aggressively whisking the broken sauce, trying to force the slick pool of butter back into the cream cheese while guests politely pretended not to notice.

The problem with most hot seafood dips lies in the delicate protein matrix of the seafood combined with high-moisture vegetables like spinach. Bear with me here, because this is where the physics of cooking comes into play: when you bake them together at high heat, the spinach cells collapse and dump water, while the proteins in the shrimp tighten and squeeze out their own moisture, completely shattering your emulsified cheese base.

But there is an incredibly easy fix.

By par-cooking the shrimp, thoroughly squeezing the spinach in a clean kitchen towel until your knuckles turn white, and using a low-moisture starch stabilizer, you get a perfectly cohesive scoop every single time.

If you love rich, crowd-pleasing appetizers like our Hot Shrimp Dip, this elevated version brings a luxurious touch that makes any weekend gathering feel absolutely perfect.

Ingredients

• 225g (8 oz) cream cheese, softened
• 115g (1/2 cup) sour cream
• 60g (1/4 cup) mayonnaise (Duke's preferred)
• 150g (1.5 cups) shredded mozzarella cheese, divided
• 50g (1/2 cup) freshly grated Parmesan cheese
• 225g (8 oz) raw shrimp, peeled, deveined, and chopped into bite-sized pieces
• 225g (8 oz) lump crab meat, drained and picked through for shells
• 150g (5 oz) fresh baby spinach
• 2 cloves garlic, minced
• 1 tsp Old Bay seasoning
• 1/2 tsp Diamond Crystal kosher salt
• 1 tsp cornstarch

Directions

1. Preheat your oven to 375°F (190°C). Lightly grease a 1.5-quart baking dish.
2. Heat a splash of olive oil in a skillet over medium heat. Sauté the chopped shrimp and minced garlic for 2 to 3 minutes until the shrimp just turns pink; fish them out with a slotted spoon and set aside. Sautéing the garlic in olive oil first coaxes out those oil-soluble flavor compounds, infusing the entire base.
3. In the same skillet, wilt the fresh spinach. Transfer the wilted spinach to a clean kitchen towel and squeeze out every single drop of excess water over the sink. Squeezing spinach with a tiny strainer got annoying fast, so stick to the towel method. Rough chop the spinach.
4. In a large mixing bowl, vigorously beat the softened cream cheese, sour cream, mayonnaise, cornstarch, Old Bay, and Diamond Crystal kosher salt until completely smooth and emulsified.
5. Fold in the chopped shrimp, squeezed spinach, half of the mozzarella, and all of the Parmesan cheese.
6. Gently fold in the lump crab meat, taking care not to break up the large, sweet lumps of meat.
7. Spread the mixture evenly into your prepared baking dish and top with the remaining mozzarella cheese.
8. Bake for 15 to 20 minutes until bubbling around the edges, then pop under the broiler for 2 minutes until the cheese top is golden brown and blistered.

Notes

• We highly recommend using Duke's mayonnaise for its high egg-yolk content, which aids in emulsification. If using Diamond Crystal kosher salt, use 1/2 teaspoon; if substituting fine table salt, reduce this to 1/4 teaspoon.
• The addition of 1 teaspoon of cornstarch acts as a physical barrier that prevents the dairy proteins from clumping together and releasing water, keeping your cheese sauce perfectly velvety so it clings to every chip.
• Keep a hawk-like eye on the oven during the final broiling step. The high fat content in the cheese can go from beautifully blistered to completely scorched in less than thirty seconds.
• After a day in the fridge, the dip will solidify significantly as the fats cool. Reheat it gently to avoid breaking the emulsion.

Serving Suggestions

Complete your appetizer spread by pairing this bubbling hot dip with crunchy, sturdy dippers that can handle a heavy scoop without breaking.

• Warm, toasted baguette slices brushed with garlic butter.
• Sturdy tortilla chips or pita chips.
• Crisp celery sticks and cucumber slices for a refreshing contrast.
• A side of Cheesy Biscuit Treats to scoop up the extra sauce.
• Pair with a cold, crisp white wine like Pinot Grigio or Sauvignon Blanc.

Storage and Reheating

Leftovers are rare, but they keep beautifully.

Store any remaining dip in an airtight container in the refrigerator for up to three days. Because of the delicate nature of the crab and shrimp, we do not recommend freezing this dip, as the freezing process will destroy the texture of the seafood and cause the dairy to separate upon thawing.

To reheat, place the desired portion in an oven-safe dish, cover with foil, and bake at 350°F (175°C) for 10 to 12 minutes until warmed through.

Avoid the microwave if you can.

Microwaving heats unevenly and can easily overcook the shrimp, turning them rubbery while causing the cheese oils to separate.

Ingredient Substitutes

If you need to swap things out based on what is in your pantry, here are our tested substitutions:

1. Lump Crab Meat: You can substitute claw meat for a more budget-friendly option, though it has a slightly stronger seafood flavor. Avoid imitation crab if possible, as it adds unnecessary sweetness and moisture.
2. Fresh Spinach: Frozen chopped spinach works perfectly. Just ensure you thaw it completely and squeeze out the water using a potato ricer or clean kitchen towel.
3. Shrimp: If you want to skip the shrimp, you can double the crab meat, or swap it for chopped lobster tail for an ultra-luxurious twist similar to our Seafood Lasagna Roll-Ups.
4. Sour Cream: Plain Greek yogurt can be used in a 1:1 ratio, though it will add a slightly tangier flavor profile to the finished dip.

I hope this bubbling, cheesy masterpiece brings as much joy to your next gathering as it does to mine. Just remember to squeeze that spinach like you mean it, pour yourself a cold drink, and enjoy every single scoop.
