🛒 Ingredients
Baby Potatoes
Small potatoes provide the hearty foundation of this slow-cooker shrimp boil. They become tender and soak up the buttery, seasoned cooking juices. If your potatoes are larger than bite-size, cut them in half so they cook evenly.
Corn
Fresh corn on the cob adds natural sweetness and classic shrimp-boil flavor. Cut the corn into smaller pieces so it is easy to serve and eat.
Sausage
Smoked sausage brings savory, meaty flavor and pairs beautifully with the sweetness of the corn and shrimp. Kielbasa or another fully cooked smoked sausage works well.
Shrimp
Use large or jumbo shrimp, preferably peeled and deveined. Keeping the shrimp relatively large helps prevent them from becoming overcooked and rubbery.
Butter
Butter melts throughout the slow cooker, coating the potatoes, sausage, corn, and shrimp with rich flavor.
Cajun or Old Bay Seasoning
This is where the signature shrimp-boil flavor comes from. Cajun seasoning gives the dish a bolder, spicier kick, while Old Bay offers a classic savory seafood flavor.
Lemon
Fresh lemon juice brightens the rich butter and seasoning. Serve additional lemon wedges alongside the finished dish for squeezing over each portion.
Fresh Parsley
A sprinkle of parsley adds freshness, color, and a light herbal finish.
🍳 How to Make a Slow-Cooker Shrimp Boil
1. Prepare the Ingredients
Wash the baby potatoes thoroughly. Cut the corn into smaller sections and slice the sausage into bite-size pieces. If necessary, peel and devein the shrimp.
2. Start with the Potatoes
Place the baby potatoes in the slow cooker first. They take longer to become tender than the other ingredients, so positioning them toward the bottom helps them cook properly.
3. Add Corn and Sausage
Add the corn pieces and sliced sausage over the potatoes. The sausage will release savory juices as it heats, adding even more flavor to the dish.
4. Add Butter and Seasoning
Add the butter and sprinkle generously with Cajun or Old Bay seasoning. Toss the ingredients gently if your slow cooker allows enough room to do so.
5. Cook Until the Potatoes Are Tender
Cover and cook until the potatoes are fork-tender. The exact cooking time will vary depending on your slow cooker and the size of the potatoes.
6. Add the Shrimp
Add the shrimp toward the end of cooking rather than leaving them in the slow cooker for the entire cooking period. Shrimp cook quickly, and this helps keep them tender and juicy instead of rubbery.
Cook just until the shrimp are opaque and cooked through.
7. Toss and Finish
Gently toss everything together so the shrimp, potatoes, corn, and sausage are coated in the buttery seasoning. Sprinkle generously with fresh parsley.
8. Serve With Lemon
Transfer the slow-cooker shrimp boil to a large serving platter or serve directly from the slow cooker. Add plenty of fresh lemon wedges and let everyone squeeze lemon over their portion.

👩🍳 Pro Tips for the Best Slow-Cooker Shrimp Boil
Don’t overcook the shrimp. This is the most important tip. Shrimp need much less cooking time than potatoes, so add them near the end.
Cut the potatoes evenly. Similar-sized pieces will cook at approximately the same rate.
Use plenty of seasoning. Potatoes and corn can absorb a surprising amount of flavor, so season generously and adjust to taste.
Choose a fully cooked smoked sausage. Kielbasa and similar sausages work particularly well and make preparation especially easy.
Add lemon at the end. Fresh lemon juice provides a bright contrast to the buttery ingredients and shouldn’t be overlooked.
Want it spicy? Add extra Cajun seasoning or a pinch of cayenne pepper for additional heat.
Don’t overcrowd the slow cooker. If you’re making a larger batch, use a sufficiently large slow cooker so the ingredients can cook evenly.
