Before you start
Before cooking, split the lobster tails if they aren't already cut. Using kitchen shears, cut through the top shell lengthwise and gently pull the meat up and over the shell so it sits exposed. Peel and devein the shrimp if needed.
Smash the garlic cloves with the flat side of a knife to release their flavor. Measure the corn, butter, lime juice, chili powder, and cilantro. Have the slow cooker ready and the jasmine rice steaming before you start — the seafood cooks quickly once the slow cooker is hot.

Instructions
Layer and Season
- Layer the Seafood and AromaticsPlace the split lobster tails and peeled jumbo shrimp in the bottom of a 6-quart slow cooker in a single layer. Scatter the frozen sweet corn kernels and smashed garlic cloves evenly over the seafood. Do not stir — layering keeps the shellfish from overcooking on the bottom.Look for The slow cooker should look full but not overcrowded; the seafood and corn should be evenly distributed.Tip If the lobster tails are frozen, thaw them in the refrigerator overnight before splitting. Pat dry with paper towels before adding.
- Make the Chili-Lime ButterIn a small bowl, stir together the melted unsalted butter, fresh lime juice, and chili powder until well combined. Pour the mixture evenly over the seafood and corn. Sprinkle the chopped cilantro over the top.Look for The butter mixture should be a uniform amber color with the chili powder fully incorporated.Tip Melt the butter gently in the microwave or on the stovetop — it should be warm but not bubbling hot when poured over the seafood.
At the end of this phase, the slow cooker holds a colorful mound of raw lobster tails, pink shrimp, golden corn, and ivory garlic cloves, all coated in the amber chili-lime butter. The cilantro is scattered on top. The butter should be evenly distributed, and the garlic cloves should be nestled among the corn and seafood. This is the 'dump it in' stage — everything is ready to cook.
Slow-Cook
- Slow-Cook the Seafood BoilCover the slow cooker and cook on LOW for 2 hours, or until the lobster tails are opaque and the shrimp are pink and firm. Do not lift the lid during the first 90 minutes — the steam is what cooks the seafood gently.Look for The butter should be bubbling gently around the edges, and the aroma of garlic and chili should fill the kitchen.Safe temperature 145°F (63°C) internal temperature (shellfish)Tip Slow cookers vary; start checking at 1 hour 45 minutes if your model runs hot. The seafood is done when the lobster meat is white and the shrimp curl into a loose C shape.
After 2 hours on low, the slow cooker is bubbling gently. The butter sauce is glossy and fragrant with garlic and chili. The lobster tails have turned from translucent to opaque white, and the shrimp are pink and curled.
The corn is tender and has absorbed some of the butter. The kitchen smells rich and savory. Check that the seafood is cooked through — the internal temperature should be at least 145°F (63°C).
Serve
- Serve the Seafood Over RiceUsing a slotted spoon, lift the lobster tails, shrimp, corn, and garlic from the butter sauce and divide among serving bowls or plates. Spoon a little extra chili-lime butter over the top. Serve immediately with steamed jasmine rice and lemon wedges on the side.Look for The lobster tails should be glossy with butter, and the shrimp should be pink and tender.Tip For a prettier presentation, place the lobster tails on top of the rice and tuck the lemon wedges alongside. Squeeze fresh lemon over everything before eating.
The plated dish shows glossy lobster tails and shrimp over steamed jasmine rice, with corn and garlic scattered around. The butter sauce pools at the base of the bowl, and lemon wedges sit on the side. The seafood should be steaming hot, and the lobster meat should flake easily with a fork. A final squeeze of lemon adds brightness.
Common mistakes
Overcooking is the most common mistake — the low setting is essential; high heat will make the shrimp rubbery and the lobster tough. Don't stir the pot during cooking; the seafood is delicate and stirring can break it apart.
Avoid lifting the lid repeatedly, as each peek releases steam and extends the cooking time. If the sauce looks separated, it's fine — the butter and lime juice will emulsify when you spoon it over the seafood. Finally, don't skip the lemon wedges; the acidity brightens the rich butter.
How to tell it’s done
The dish is done when the lobster tails are opaque and the meat is white with a slight pink blush, and the shrimp are pink and curled into a loose C shape. The internal temperature of the thickest part of the lobster tail and the shrimp should reach at least 145°F (63°C).
The butter sauce should be bubbling gently around the edges, and the garlic should be soft and golden. If the shrimp are still translucent in the center, cook for another 10 minutes and check again.
- Shellfish: 145°F (63°C) in the thickest part
