How to Make Slow Cooker Cajun Shrimp Boil

Prepare the Ingredients: Start by washing and halving the baby red potatoes, slicing the smoked andouille sausage, roughly chopping the yellow onion, and mincing the garlic. Shuck the corn and cut it into 3 to 4 smaller pieces. This ensures everything cooks evenly!
Layer in the Slow Cooker: In a 6-quart or 8-quart slow cooker, add the halved potatoes, sliced andouille sausage, chopped onion, and minced garlic. This delicious combination will create a flavorful base for your shrimp boil.
Add the Broth and Spices: Pour the broth over the ingredients, then sprinkle the Cajun seasoning and Old Bay seasoning evenly on top. Squeeze the juice from 1 lemon into the pot and toss in the squeezed lemon wedges. Stir gently to combine for that perfect blend!
Cook Low and Slow: Cover the crockpot with the lid and cook on LOW for 5 to 6 hours or on HIGH for 3 to 4 hours, until the potatoes are just barely fork-tender. Your kitchen will start to smell heavenly!
Incorporate the Corn: About 45 minutes before the cooking time is up, stir in the corn pieces. Cover and continue cooking on HIGH for that sweet crunch in every bite.
Add the Shrimp: Exactly 15 minutes before serving, stir in the raw shrimp. Cover and cook on HIGH for 10 to 15 minutes, watching closely until the shrimp turn pink and are fully cooked.
Finish and Serve: Turn off the slow cooker and carefully remove the cooked lemon wedges with tongs. Pour the melted butter evenly over the finished boil and sprinkle with chopped parsley. Serve hot directly from the crockpot, with fresh lemon wedges on the side for extra zing!

Optional: A sprinkle of extra Cajun seasoning adds an extra kick!

Slow Cooker Cajun Shrimp Boil Recipe FAQs

How do I choose the best shrimp for my Slow Cooker Cajun Shrimp Boil?
Absolutely! When selecting shrimp, look for extra-large raw shrimp that are firm to the touch and have a fresh ocean scent. Avoid any with dark spots or a strong fishy odor. For the best flavor, opt for shrimp that are still peeled but deveined with the tail-on, as they retain moisture and flavor during cooking.

What should I do if my shrimp boil turns out too spicy?
Very! If you find your shrimp boil is too spicy for your taste, you can balance the heat by adding more broth or some coconut milk to the pot.
