This slow cooker lobster tail recipe turns a fancy seafood dinner into a hands-off weeknight meal.
Split lobster tails and jumbo shrimp simmer in a rich parsley-garlic butter with bright lemon and briny capers, creating a golden sauce that begs to be spooned over rice. The slow cooker does all the work, delivering tender, buttery seafood every time.
Slow cooker seafood might sound unusual, but it’s one of the easiest ways to cook lobster tails and shrimp without constant attention. The gentle heat of the Crockpot poaches the seafood in a fragrant bath of white wine, lemon, and herb butter, so the meat stays moist and tender.
This recipe comes together in minutes—just layer the ingredients and walk away. Serve it over steamed rice or with crusty bread to soak up every drop of the sauce.
Ingredients
- 4 split cold-water lobster tails
- 1 lb raw jumbo shrimp, peeled and deveined
- 1 large Meyer lemon, thinly sliced
- 3 tbsp capers, drained
- 1/2 cup dry white wine
- 6 tbsp parsley-garlic scampi butter, softened
Why this recipe works
The slow cooker provides a gentle, even heat that is perfect for delicate seafood. Unlike high-heat methods that can easily dry out lobster tails, the low, moist environment of the Crockpot keeps the meat succulent and tender.
The butter and wine create a flavorful poaching liquid that infuses the seafood as it cooks.
Because everything goes into the pot at once, there is no need to stand over a hot stove. The hands-off method allows the flavors to meld and develop over a few hours, resulting in a deeply savory sauce.
The lemon and capers cut through the richness of the butter, while the garlic and parsley add aromatic depth.
Notes and substitutions
Use the best-quality lobster tails you can find—cold-water tails from Maine or New Zealand are sweet and tender. If using frozen tails, thaw them completely in the refrigerator before cooking. Jumbo shrimp (16–20 count) work best here because they hold up well during the low-and-slow cooking process.
The parsley-garlic scampi butter is the heart of this dish. You can make it by mixing softened butter with minced garlic, chopped fresh parsley, salt, and pepper. If you prefer a store-bought version, look for a garlic-herb compound butter. For a dairy-free alternative, use a vegan butter substitute.
- Meyer lemon: Regular lemon or lime for a brighter, slightly more acidic note.
- dry white wine: Seafood stock or chicken broth mixed with 1 tablespoon lemon juice.
- parsley-garlic scampi butter: Store-bought garlic butter mixed with extra chopped parsley.
- jumbo shrimp: Large sea scallops or a mix of shellfish, adjusting cooking time as needed.
