Tips for success
For the best texture, use jumbo or extra-large shrimp—they stay juicy during the long cook. If you use smaller shrimp, reduce the cooking time to 2 hours and check for doneness.
When selecting crab, look for clusters that are heavy for their size, indicating they're full of meat. If you can't find snow crab, king crab or Dungeness crab work well, but adjust the cooking time based on the size of the legs.
The sauce is the star—don't skimp on the butter. Use a good-quality unsalted butter and season it generously with Cajun spice and smoked paprika. If you want a little heat, add a pinch of cayenne or a few dashes of hot sauce.
The lemon juice is essential for balancing the richness; add it just before pouring the butter over the seafood. You can also garnish with fresh parsley if you like, though it's not required.
Variations
- Spicy Andouille Sausage: Add 8 ounces sliced andouille sausage to the slow cooker with the seafood for a smoky, spicy flavor. The sausage releases its oils into the butter sauce, adding depth. Cook as directed—the sausage is already cooked, so it just needs to heat through.
- Cajun Chicken and Seafood: Replace half the shrimp with boneless, skinless chicken thighs cut into chunks. The chicken will cook in the same time and absorb the Cajun butter. Ensure the chicken reaches 165°F (74°C) before serving.
- Veggie-Packed Boil: Add 2 cups of baby potatoes and 2 ears of corn cut into rounds along with the seafood. The potatoes will absorb the butter and become tender. Increase the cooking time to 3 1/2 hours if the potatoes are large.
- Mild Garlic Butter: For a milder version, omit the Cajun seasoning and use 1 cup of melted butter mixed with 1 teaspoon of smoked paprika and 1/2 teaspoon of garlic powder. The dish will still be rich and garlicky but without the heat.
Storage and make-ahead
- Fridge
- Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave.
- Freezer
- Freeze cooked seafood and sauce in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator and reheat gently.
- Reheat
- Reheat in a saucepan over low heat, adding a splash of water or butter to loosen the sauce. Avoid boiling to prevent the shrimp from becoming tough.
Store leftover seafood and sauce in an airtight container in the refrigerator for up to 3 days. The flavors will meld further, but the shrimp may become slightly softer. To reheat, place the leftovers in a saucepan over low heat, adding a splash of water or butter to loosen the sauce. Avoid microwaving, as it can make the shrimp rubbery. The corn and garlic will absorb more flavor as they sit.
You can prepare the ingredients up to a day in advance. Clean the shrimp, smash the garlic, and measure the butter sauce and lemon juice. Store them separately in the refrigerator.
When ready to cook, layer everything in the slow cooker and pour the butter over. The cooking time remains the same. This is a great option for entertaining—you can have everything ready to go and just turn on the slow cooker when guests arrive.
Serving ideas
Serve the seafood boil directly from the slow cooker or transfer to a large platter for a family-style presentation. Provide small bowls for the discarded shells and plenty of napkins.
Steamed jasmine rice is the perfect accompaniment—it soaks up the buttery sauce and balances the richness. Lemon wedges on the side let everyone brighten their portion to taste. For a complete meal, add a simple green salad or crusty bread to mop up the sauce.
This dish is hearty enough to stand alone as a main course. The crab and shrimp are the centerpiece, while the corn and garlic act as built-in sides. If you're serving a crowd, you can double the recipe and use a larger slow cooker or cook in batches. The leftovers are just as delicious the next day—try them over rice or in a seafood pasta. The sauce is also great for dipping crusty bread.

- 1/4 cup fresh lemon juice
- steamed white jasmine rice, for serving
- lemon wedges, for serving
Instructions
- Place the snow crab leg clusters and raw jumbo shrimp in the bottom of a 7-quart slow cooker. Spread them out evenly so they cook uniformly.
