This slow-cooker lobster tail and shrimp dish is the easiest way to get a restaurant-quality seafood boil at home without standing over a pot. Four split lobster tails and a pound of jumbo shrimp simmer gently in a chili-lime butter with sweet corn and roasted garlic cloves.

Whether it's a weeknight treat or a weekend dinner for guests, this slow-cooker seafood boil delivers big flavor with minimal fuss. Serve it over steamed jasmine rice with lemon wedges to brighten every bite.

Ingredients

Why this recipe works

The slow cooker's low, steady heat is ideal for delicate shellfish. Unlike boiling or pan-searing, which can easily overcook lobster and shrimp, the gentle simmer in the slow cooker keeps them moist and tender. The butter and lime juice create a flavorful poaching liquid that infuses the seafood as it cooks, so every bite is rich and aromatic.

Layering the ingredients without stirring means the seafood stays on top, where it cooks evenly without breaking apart. The corn and garlic on the bottom absorb the buttery juices, becoming soft and sweet. The chili-lime butter melts and emulsifies into a glossy sauce that coats everything, and the cilantro adds a fresh, herbal finish.

Notes and substitutions

Use cold-water lobster tails if possible — they have firmer, sweeter meat. Split them down the middle with kitchen shears so the meat is exposed to the butter.

Jumbo shrimp (16-20 per pound) work best; smaller shrimp will cook faster and may become tough. Frozen sweet corn is convenient and holds up well, but fresh corn cut from the cob adds extra sweetness.

The chili-lime butter is the backbone of this dish. Use fresh lime juice, not bottled, for the brightest flavor. Adjust the chili powder to taste — start with 1 teaspoon for a mild warmth, or add more for extra heat. Unsalted butter lets you control the salt level; if using salted butter, skip any additional salt in the recipe.

• frozen sweet corn kernels: Fresh corn cut from 3 ears (about 2 cups) — add with the seafood; it will soften during cooking.
• unsalted butter: Salted butter works, but reduce added salt elsewhere; the chili-lime butter will be slightly saltier.
• chili powder: Use 1/2 tsp smoked paprika plus 1/2 tsp cayenne for a smokier heat, or 1 tsp ancho chili powder for milder flavor.
• jumbo shrimp: Large shrimp (16-20 per lb) work; reduce cooking time by 15 minutes if using smaller shrimp.
