Old Bay Butter Lobster Tails: Easy Crockpot Seafood Boil Tips, FAQ & printable recipe

Tips for success

For the best texture, avoid stirring the slow cooker during cooking. The seafood stays submerged in the butter and steams gently, which keeps it moist.

If you prefer a thicker sauce, remove the seafood after cooking and simmer the remaining butter on the stovetop until reduced.

Serve with crusty bread or steamed rice to soak up every drop of the garlic butter sauce. A squeeze of fresh lemon brightens the richness. If you have leftover sauce, refrigerate it and use it to sauté shrimp or vegetables later.

Variations

• Cajun Style: Replace Old Bay with Cajun seasoning and add a diced andouille sausage. The smoky sausage complements the seafood and adds a hearty bite. Increase the garlic and include a pinch of cayenne for extra heat.
• Lemon Herb: Add the zest and juice of one lemon to the butter mixture, and toss in fresh thyme and parsley. Omit the Old Bay and use a milder seasoning like paprika and black pepper. Serve with extra lemon wedges.
• Spicy Sriracha: Stir 2 tablespoons of sriracha into the melted butter before pouring it over the seafood. Reduce the Old Bay to 1 tablespoon to balance the heat. Garnish with sliced green onions and sesame seeds.
• Vegetable Boost: Add sliced mushrooms, corn on the cob, or baby potatoes to the slow cooker along with the other vegetables. The vegetables will absorb the butter sauce and become tender. Adjust cooking time if adding potatoes—they may need an extra 30 minutes.

Storage and make-ahead

Fridge

Store in an airtight container for up to 3 days. Reheat gently to avoid toughening the seafood.

Freezer

Freeze in a sealed container for up to 1 month. Thaw overnight in the refrigerator before reheating.

Reheat

Reheat in a skillet over low heat with a splash of butter or broth until warmed through.

Store leftovers in an airtight container in the refrigerator for up to 3 days. The seafood will absorb more flavor as it sits, but it's best eaten within a day or two.

Reheat gently in a skillet over low heat with a splash of butter or broth to keep it moist.

You can prep the vegetables and split the lobster tails a day ahead. Store them separately in the refrigerator.

Assemble the slow cooker in the morning and cook as directed. The sauce can also be made ahead and refrigerated; melt it before pouring over the seafood.

Serving ideas

Serve this seafood boil as a main course with steamed jasmine rice and lemon wedges. The rice soaks up the buttery sauce, while the lemon adds a bright contrast. For a low-carb option, serve over cauliflower rice or with a simple green salad.

This dish also works well as a party centerpiece. Set out the slow cooker with bowls of extra sauce and crusty bread, and let guests serve themselves.

The seafood is easy to eat with forks, and the vegetables are soft enough to scoop up with bread.

Old Bay Butter Lobster Tails: Easy Crockpot Seafood Boil

Prep 15 minCook 3 hTotal 3 h 15 minServes 4

Ingredients

• 4 split cold-water lobster tails
• 1 lb raw jumbo shrimp, peeled and deveined
• 1 cup diced red and green bell peppers
• 1/2 cup diced sweet Vidalia onion
• 1/2 cup celery ribbons
• 1/2 cup melted garlic herb butter
• 2 tbsp Old Bay seasoning

Instructions

1. Place the split lobster tails and raw jumbo shrimp in the bottom of a 6-quart slow cooker. Arrange them in a single layer if possible, so they cook evenly. Spread the diced bell peppers, sweet onion, and celery ribbons over the seafood.
2. Pour the melted garlic herb butter evenly over the vegetables and seafood. Sprinkle the Old Bay seasoning over the top, making sure to coat the exposed surfaces. Do not stir—the layers will meld as they cook.
3. Cover the slow cooker and cook on LOW for 2 1/2 to 3 hours, until the lobster meat is opaque and the shrimp are pink and firm. The butter will melt and bubble gently around the seafood.
4. Insert an instant-read thermometer into the thickest part of a lobster tail and into a shrimp. The temperature should read at least 145°F (63°C). The lobster meat should be white and tender, not translucent.
5. Using a slotted spoon, lift the lobster tails, shrimp, and vegetables out of the butter bath and onto a serving platter or individual plates. Spoon some of the garlic butter sauce over the top. Serve hot with steamed rice and lemon wedges if desired.
