Ingredients

Why this recipe works

Slow cooking the shrimp gently poaches them in the butter sauce, keeping them tender and juicy instead of tough and rubbery.

The low heat allows the flavors of the Cajun seasoning, garlic, and lemon to meld together without overcooking the seafood. This method is forgiving and foolproof, making it ideal for weeknight cooking.

The butter sauce acts as a cooking medium and a flavor carrier, coating every piece of shrimp and corn with a rich, savory finish. The corn releases its natural sweetness as it cooks, balancing the heat of the Cajun spices. The result is a cohesive dish where every component complements the others.

Notes and substitutions

Choose jumbo shrimp (21–25 per pound) for the best texture and presentation. They hold up well during the long cook time and stay plump.

Frozen corn works perfectly here and saves prep time; it thaws and absorbs the butter sauce as it cooks. Smashed garlic cloves, rather than minced, provide a mellow, sweet roasted flavor.

A 7-quart slow cooker is ideal for this quantity. If using a smaller cooker, reduce the shrimp to 1 1/2 pounds. Cajun seasoning varies in heat; start with 2 tablespoons and adjust to taste. For a milder version, use 1 tablespoon Cajun seasoning and 1 tablespoon smoked paprika.

• frozen sweet corn: fresh corn kernels cut from 2 ears (about 2 cups)
• unsalted butter: salted butter, reduce Cajun seasoning to 1 1/2 tbsp
• Cajun seasoning: 1 tbsp paprika, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp cayenne, 1/2 tsp black pepper
• jumbo shrimp: large shrimp, reduce cook time to 1 1/2 hours
