Bayou Butter Garlic Corn Snow Crab: One-Pot Slow Cooker Seafood

Snow crab and jumbo shrimp simmer in a rich, spiced butter sauce with sweet corn and garlic—all in one slow cooker. This is the kind of dinner that feels like a special occasion but comes together with almost no effort.

Just layer the ingredients, pour the butter, and let the slow cooker do the work while you get on with your day. The result is a tender, sweet, and savory seafood boil that's perfect for a casual weeknight or a weekend gathering.

This slow cooker seafood dish brings together the best of a Louisiana-style boil in a hands-off format. Sweet snow crab clusters and jumbo shrimp cook gently in a buttery sauce infused with garlic, paprika, and a hint of Cajun spice.

Corn kernels add a pop of sweetness, while the garlic cloves soften into mellow, spreadable nuggets. Serve it over steamed jasmine rice to soak up every last drop of the sauce. The recipe is forgiving and adaptable—use whatever seafood looks best at the market, and adjust the heat to your liking.

Ingredients

Why this recipe works

The slow cooker provides a gentle, even heat that cooks the seafood without toughening it. Unlike a rapid boil, the low temperature lets the shrimp stay plump and the crab meat tender. The butter sauce slowly infuses the corn and garlic, so every bite carries the same rich flavor. The hands-off method means no standing over a pot, and the dish keeps warm until you're ready to serve.

The combination of butter, garlic, and lemon is a classic that complements the natural sweetness of crab and shrimp. The paprika and Cajun seasoning add depth without overwhelming the seafood.

Because the ingredients are layered in the slow cooker, the flavors meld together as they cook, creating a cohesive dish. The corn absorbs the spiced butter, turning into a side dish all on its own.

Notes and substitutions

Snow crab leg clusters are usually sold precooked and frozen; they just need to be heated through. If using raw crab, adjust the cooking time accordingly.

Jumbo shrimp are ideal because they hold up well during the long cook, but you can use large or extra-large shrimp—just reduce the cooking time slightly. The garlic should be smashed, not minced, so it softens and sweetens without burning.

The Cajun garlic-paprika butter is the heart of this recipe. If you don't have it on hand, melt 1 cup of unsalted butter and stir in 1 tablespoon of Cajun seasoning and 1 teaspoon of smoked paprika. Adjust the spice level to your preference. The lemon juice brightens the rich butter and balances the heat. For a milder version, use half the Cajun seasoning.
