Cook Time: 3½–4 hours
Total Time: About 4 hours
Servings: 4–6
Difficulty: Easy
Method: Slow Cooker

🛒 Ingredients

1 lb (450 g) raw large shrimp, peeled and deveined, tails on or off
1½ lb (680 g) baby potatoes, halved if large
4 ears corn, cut into 2–3-inch pieces
½ cup (113 g) unsalted butter, melted
2 tbsp seafood seasoning, such as Old Bay-style seasoning
1 tbsp Cajun seasoning
1 lemon, cut into wedges
2 tbsp fresh parsley, chopped
½ cup water or low-sodium chicken/seafood broth, optional, if your slow cooker needs additional moisture

Optional Additions

12 oz smoked sausage, sliced
4 cloves garlic, minced
½ tsp red pepper flakes
Extra melted butter for dipping
Hot sauce, for serving

👩‍🍳 Instructions

1. Prepare the Slow Cooker

Lightly grease the inside of a 6-quart slow cooker or simply add the ingredients directly to the crock.

Place the baby potatoes in the bottom.

If using larger baby potatoes, cut them in half so they cook evenly.

2. Make the Seasoned Butter

In a small bowl, combine the melted butter, seafood seasoning, and Cajun seasoning.

If using garlic, stir in the minced garlic as well.

Mix thoroughly.

3. Add the Potatoes and Corn

Arrange the corn pieces over the potatoes.

Pour about ⅔ of the seasoned butter mixture over the potatoes and corn.

Toss gently with a large spoon or silicone spatula so everything gets coated.

Squeeze the juice from 1–2 lemon wedges over the vegetables, then place several lemon wedges into the slow cooker.

4. Slow Cook the Potatoes and Corn

Cover and cook on:

HIGH for 2½–3 hours

LOW for 4–5 hours

The potatoes should be fork-tender before adding the shrimp.

Cooking times can vary depending on the size of the potatoes and the slow cooker.

🍤 5. Add the Shrimp

Pat the shrimp dry with paper towels.

Arrange them over the cooked potatoes and corn.

Drizzle the remaining seasoned butter over the shrimp.

Cover and cook on HIGH for approximately 15–25 minutes, or until the shrimp are pink, opaque, and cooked through.

Avoid cooking the shrimp for too long, as they can quickly become rubbery.

6. Finish With Lemon & Parsley

Remove the lemon wedges if desired.

Squeeze fresh lemon juice over the entire shrimp boil.

Sprinkle generously with chopped fresh parsley.

Gently toss the ingredients together so the buttery Cajun seasoning coats everything.

🍽️ 7. Serve

Transfer the shrimp boil to a large serving platter or spread it directly onto a parchment-lined table for a casual seafood-boil presentation.

Serve immediately with:

Extra melted butter
Fresh lemon wedges
Hot sauce
Additional Cajun seasoning
Crusty bread for soaking up the buttery juices

⭐ Chef’s Tips

Add the Shrimp Last

Shrimp cook much faster than potatoes and corn. Adding them during the final 15–25 minutes keeps them juicy and tender.

Don’t Skip the Butter

The seasoned butter carries the seafood and Cajun flavors throughout the dish and helps coat the potatoes and corn.

Check the Potatoes First

Before adding the shrimp, pierce a potato with a fork. It should be tender enough to pierce easily.

Cut Large Potatoes

If some baby potatoes are considerably larger than others, halve them so everything finishes cooking at roughly the same time.

Watch the Seasoning

Seafood seasoning and Cajun seasoning can both contain salt. Taste the finished butter sauce before adding any additional salt.

🌭 Optional Sausage Addition

For an even heartier shrimp boil, add 12 oz smoked sausage, sliced into 1-inch pieces.

Place the sausage over the potatoes before adding the corn.

The sausage will release its smoky, savory flavor into the seasoned butter as everything cooks.

🌶️ Make It Spicy

For a spicy Cajun-style boil, add:

½–1 tsp red pepper flakes
1–2 tsp hot sauce
Extra Cajun seasoning
Sliced fresh jalapeño

For a milder version, simply omit the red pepper flakes and use a mild Cajun seasoning.

🧈 Easy Garlic Butter Variation

For a richer garlic-butter flavor, add 4 minced garlic cloves to the melted butter.

Warm the butter and garlic together over low heat for about 1 minute before adding the seafood and Cajun seasonings.

This creates an especially fragrant sauce for dipping.

🥖 Serving Suggestions

A shrimp boil is perfect with simple sides such as:

Crusty French bread
Garlic bread
Coleslaw
Green salad
Hush puppies
Cornbread
Extra lemon wedges
Cajun dipping sauce

Don’t forget plenty of napkins—this is deliciously messy food!

🧊 Storage

Allow leftovers to cool before transferring them to an airtight container.

Refrigerate for up to 3 days.

Because shrimp can become tough when repeatedly reheated, reheat gently and only until warmed through.

Reheating

Place leftovers in a covered skillet over low heat with a small splash of water or broth.

Heat gently until warmed.

You can also microwave individual portions in short intervals, stirring between each interval.

🍤 Final Result

This Slow Cooker Shrimp Boil delivers all the fun of a traditional seafood boil with far less work.

You’ll get buttery Cajun shrimp, tender potatoes, sweet corn, bright lemon, and fresh parsley in every bite. Add smoked sausage for an even heartier meal, then serve everything with extra melted butter and plenty of crusty bread for soaking up that irresistible sauce.

Easy, buttery, spicy, and made for sharing! 🍤🥔🌽🧈
