Step-by-Step Instructions
- Prep the slow cooker insert: Clean your slow cooker and ensure the insert is dry and ready for stacking your ingredients.
- Layer the potatoes, corn, and sausage: Place the whole or halved Little Potato Company creamers, sweet corn cobs, and sliced smoked sausage at the bottom of the slow cooker insert.
- Add seasonings and butter: Scatter generous amounts of Old Bay seasoning and Cajun seasoning over the potatoes, corn, and sausage, then dot Land O’Lakes unsalted butter and fresh minced garlic across the top.
- Add lemon and broth (or water): Squeeze fresh lemon juice from the lemon halves over the mixture and drop the squeezed lemon rinds right into the slow cooker for extra citrus aroma.
- Slow cook the hearty base: Cover the slow cooker securely with its lid and cook on LOW for 3 to 4 hours (or on HIGH for 2 hours) until the baby potatoes and corn are fork-tender.
- Add the raw shrimp: Open the lid and add the SeaPak raw shrimp directly into the hot seasoned butter bath, stirring gently to submerge them.
- Cook the shrimp: Cover and cook on HIGH for an additional 15 to 20 minutes until the shrimp turn completely pink and opaque.

Storage & Reheating Instructions
Slow cooker cajun shrimp boil stores securely in an airtight container in the refrigerator for up to 2 days, though seafood is always best enjoyed fresh. When reheating, warm individual portions gently in a skillet over low heat with a small splash of water or melted butter until heated through, avoiding high microwave power to prevent the shrimp from becoming rubbery. Freezing is not recommended for cooked shrimp and potatoes.
Budget Note
Preparing gourmet coastal seafood at home is an incredible way to feed a family or a gathering luxuriously without paying expensive seafood restaurant prices. By utilizing frozen raw shrimp, baby potatoes, and pantry spices, you create a massive, high-yield meal that feeds a crowd affordably.

Frequently Asked Questions
- Can I use frozen shrimp without thawing? It is best to thaw the SeaPak raw shrimp and pat them dry slightly before adding them during the final 20 minutes so they cook evenly without releasing excess water into the slow cooker.
- Do I need to add extra water or broth to the slow cooker? No extra water or broth is necessary because the melting butter, juices from the sausage, and citrus from the lemons create all the braising liquid required.
- Why do you add the shrimp later instead of at the beginning? Shrimp cook very quickly; adding them during the final 15 to 20 minutes prevents them from overcooking and becoming tough while the potatoes and corn tenderize.
- What side dishes pair best with cajun shrimp boil? This hearty seafood boil is an entire meal on its own, but it pairs wonderfully with warm French bread, melted garlic butter for dipping, or a crisp green salad.
