Slow Cooker Cajun Shrimp Boil

by

A traditional low-country shrimp boil usually requires a massive pot over an outdoor burner, but making a Slow Cooker Cajun Shrimp Boil lets you enjoy all those smoky, savory, and spicy flavors with almost zero effort. By letting the potatoes and corn tenderize slowly in a spiced broth before quickly steaming the shrimp at the end, everything comes out perfectly cooked and bursting with flavor.

Ingredients

  • 1.5 lbs raw large shrimp (peeled and deveined, or shell-on for maximum flavor)
  • 1 lb smoked andouille sausage or turkey sausage, sliced into coin rounds
  • 1.5 lbs baby red potatoes, washed and halved (or left whole if very small)
  • 3 ears of fresh corn on the cob, cut into thirds or quarters
  • 1 yellow onion, chopped into wedges
  • 4 cloves garlic, smashed
  • 2 cups low-income chicken broth or water
  • 2 to 3 tbsp Cajun or Creole seasoning (adjust based on how much heat you like)
  • 1 tbsp melted butter and fresh lemon juice (for finishing)
  • Fresh chopped parsley for garnish

Step-by-Step Instructions

  1. Cook the Hard Ingredients First: Place the halved red potatoes, chopped onion, and smashed garlic at the bottom of your slow cooker. Pour in the chicken broth and sprinkle 2 tablespoons of Cajun seasoning right over the vegetables. Toss to coat.
  2. Slow Cook: Cover and cook on HIGH for 3 to 4 hours (or LOW for 6 hours) until the potatoes are fork-tender.
  3. Add Corn and Sausage: About 45 minutes before the potatoes are finished, add the sliced smoked sausage and corn cob chunks into the slow cooker, pressing them down into the spiced broth so they absorb all the flavors. Cover and let them heat through.
  4. Quick-Cook the Shrimp: Shrimp cooks in minutes and can become rubbery if left in a slow cooker too long. In the last 10 to 15 minutes of cooking, lay the raw shrimp across the top of the mixture, sprinkle with the remaining pinch of Cajun seasoning, and cover. Once the shrimp turn pink and opaque, they are ready!
  5. Finish and Serve: Drizzle the melted butter and fresh lemon juice over the top, garnish with chopped parsley, and serve family-style right from the slow cooker or poured onto a large platter.

A Heart-Healthy & Low-Sodium Adaptation

To keep sodium levels balanced while keeping the signature Cajun kick, look for a salt-free or low-sodium Cajun seasoning blend, use low-sodium chicken bone broth, and load up on extra garlic, smoked paprika, and a dash of cayenne pepper for deep flavor without the heavy salt.
