It's a fantastic choice for a weekend dinner or a special occasion, and it's surprisingly simple to make. The slow cooker does all the work, infusing every bite with warm spices and garlic.
Ingredients
- 4 split cold-water lobster tails
- 1 lb raw jumbo shrimp, peeled and deveined
- 4 ears sweet yellow corn, halved
- 1 lb baby red bliss potatoes
Cajun Butter Sauce
- 1/2 cup melted Cajun garlic-paprika butter
- 2 tbsp fresh lemon juice
Why this recipe works
Slow cooking allows the lobster and shrimp to gently cook in the seasoned butter, absorbing the Cajun spices without becoming tough or rubbery. The low, steady heat keeps the seafood moist and tender. The corn and potatoes also benefit from the long cooking, becoming sweet and perfectly soft as they soak up the sauce.
This method is incredibly convenient. There's no need to boil a large pot of water or stand over a hot stove. Just layer everything in the slow cooker, pour over the sauce, and let it cook.
The result is a restaurant-quality meal with almost no hands-on time, making it perfect for busy weeknights or when you want to impress guests without the stress.
Notes and substitutions
For the best flavor, use a good-quality Cajun seasoning or make your own blend of paprika, garlic powder, onion powder, cayenne, and dried herbs. The butter should be melted and well mixed to ensure it coats everything evenly. Adjust the amount of cayenne to suit your heat preference.
You can use frozen lobster tails and shrimp; just thaw them completely in the refrigerator before cooking. If your slow cooker runs hot, check the seafood at the 2.5-hour mark to prevent overcooking.
Baby potatoes are ideal because they cook evenly and hold their shape, but you can also use regular red potatoes cut into quarters.
- lobster tails: Use large sea scallops or extra shrimp for a more budget-friendly option.
- baby red potatoes: Substitute with Yukon Gold or baby potatoes, cut in half if large.
- Cajun garlic-paprika butter: Mix 1/2 cup melted butter with 2 tsp Cajun seasoning, 1 tsp garlic powder, and 1 tsp smoked paprika.
