Ingredients

Why this recipe works

Slow cooking allows the shrimp to cook gently in the butter sauce, keeping them plump and tender rather than rubbery. The low heat also gives the corn and potatoes time to absorb the Cajun spices, so every bite is infused with flavor. The sauce reduces slightly as it cooks, concentrating the garlic, paprika, and lemon into a rich, clingy coating.

The dump-and-go method eliminates the need for constant stirring or monitoring. You can prep the ingredients in minutes and let the slow cooker handle the rest. This hands-off approach is ideal for weeknights or when you want to entertain without being tied to the stove. The result is a dish that looks and tastes like you spent hours in the kitchen.

Notes and substitutions

Choose raw jumbo shrimp (21-25 per pound) for the best texture; they hold up well during slow cooking. Peeled and deveined shrimp save time, but if you prefer, you can leave the shells on for extra flavor—just warn your guests.

For the corn, use fresh ears and cut them into 2-inch rounds; frozen corn can be substituted, but reduce the cooking time by 15 minutes.

Cajun seasoning varies in heat and salt, so adjust the amount to your preference. If you're sensitive to spice, start with 1 tablespoon and add more at the end.

Unsalted butter lets you control the salt level, but if you only have salted, reduce the added salt. Baby red potatoes are ideal because they hold their shape and cook evenly; larger potatoes should be halved or quartered.

• Cajun seasoning: Use 1 tbsp paprika, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp cayenne, 1/2 tsp oregano, and 1/2 tsp thyme.
• Baby red potatoes: Substitute Yukon Gold or new potatoes, cut into 1-inch pieces.
• Unsalted butter: Use salted butter and reduce added salt to 1/4 tsp.
• Jumbo shrimp: Use large shrimp; reduce cooking time by 15-20 minutes.
