🛒 Ingredients

For the Shrimp Boil

  • 1½–2 lbs baby potatoes, washed
  • 4 ears corn, cut into smaller pieces
  • 1½ lbs raw shrimp, peeled and deveined
  • 1 small yellow onion, cut into wedges
  • 4–5 cloves garlic, minced
  • ½ cup unsalted butter, melted
  • ½ cup chicken broth or seafood broth
  • 2–3 tablespoons Cajun seasoning, to taste
  • 1 teaspoon smoked paprika
  • ½ teaspoon black pepper
  • ½ teaspoon onion powder
  • ½ teaspoon garlic powder
  • ¼–½ teaspoon red pepper flakes, optional
  • 1 tablespoon fresh lemon juice
  • 1 lemon, cut into wedges
  • 2 tablespoons chopped fresh parsley

Optional Additions

  • 1 lb smoked sausage, sliced
  • Extra melted butter for serving
  • Old Bay-style seafood seasoning
  • Fresh parsley for garnish
  • Additional lemon wedges

👩‍🍳 Instructions

1. Prepare the Slow Cooker

Lightly grease the inside of your slow cooker or spray it with cooking spray.

Place the baby potatoes in the bottom of the slow cooker. Add the onion and corn pieces on top.

If you’re using smoked sausage, add the sliced sausage at this stage as well.

2. Make the Cajun Butter Sauce

In a small bowl, combine the melted butter, chicken or seafood broth, Cajun seasoning, smoked paprika, black pepper, onion powder, garlic powder, and red pepper flakes.

Stir everything together until well combined.

Add the minced garlic and fresh lemon juice, then stir again.

This buttery mixture is what gives the entire dish its bold, savory flavor.

3. Add the Sauce

Pour approximately two-thirds of the Cajun butter mixture over the potatoes, corn, onion, and sausage.

Toss gently so the vegetables are coated with the seasoning.

Cover the slow cooker with the lid.

4. Slow Cook

Cook on HIGH for about 3–4 hours, or on LOW for about 5–6 hours, depending on the size of your potatoes and the heat of your slow cooker.

The potatoes should be tender when pierced with a fork.

5. Add the Shrimp

Once the potatoes are nearly tender, add the raw shrimp to the slow cooker.

Pour the remaining Cajun butter mixture over the shrimp.

Cover and cook on HIGH for approximately 20–30 minutes, just until the shrimp are pink, opaque, and cooked through.

Avoid overcooking the shrimp, because they can become tough and rubbery.

6. Finish With Lemon & Parsley

Once everything is cooked, gently toss the shrimp, potatoes, corn, and sausage together so the buttery Cajun sauce coats everything.

Sprinkle with fresh parsley and squeeze fresh lemon juice over the top.

Taste and add additional Cajun seasoning or black pepper if desired.

🍳 Cooking Method

The secret to this recipe is adding the ingredients at the right time.

The potatoes need the longest cooking time, so they go into the slow cooker first. Corn, onions, and sausage can cook alongside them while they absorb the flavorful Cajun butter.

Shrimp cook much faster, so they should be added near the end. This keeps them tender, juicy, and full of flavor.

For especially large shrimp, allow a few extra minutes of cooking time, but keep a close eye on them.

🌶️ Flavor & Formation

As the ingredients slowly cook, the butter, garlic, Cajun seasoning, and broth create a rich sauce that works its way into the potatoes and corn.

The potatoes become tender and savory, while the corn develops a sweet contrast to the smoky Cajun spices. The shrimp are added at the end so they remain delicate and juicy.

A squeeze of fresh lemon brings everything together by adding a bright, zesty finish that balances the richness of the butter.

📖 A Little History

Seafood boils are strongly associated with Southern and Gulf Coast cooking traditions, where communal meals often bring together seafood, potatoes, corn, sausage, and bold seasonings.

Cajun cooking developed in Louisiana through a blend of cultural influences and a tradition of making flavorful, satisfying meals from locally available ingredients.

Traditional seafood boils are often cooked in large pots and served family-style. This slow-cooker version keeps the spirit of that comforting meal while making it easier for home cooks to prepare.

🍋 Serving Suggestions

  • Fresh lemon wedges
  • Extra melted garlic butter
  • Crusty bread
  • A simple green salad
  • Coleslaw
  • Steamed vegetables
  • Extra Cajun seasoning

For a fun presentation, spread the finished shrimp boil onto a large serving platter and drizzle it with a little extra melted butter.

💡 Helpful Tips

  • Don’t overcook the shrimp: Add them near the end of cooking.
  • Cut potatoes evenly: Similar-sized potatoes cook more consistently.
  • Adjust the spice: Use less Cajun seasoning or skip the red pepper flakes for a milder version.
  • Want more heat? Add extra Cajun seasoning or a pinch of cayenne.
  • Use fresh lemon: Lemon juice added at the end brightens the entire dish.
  • Add sausage: Smoked sausage makes the boil even heartier and adds a delicious smoky flavor.
  • Taste before serving: Cajun seasoning varies in saltiness, so adjust the seasoning at the end.
