Ingredients

1 ½ pounds large shrimp, peeled and deveined

4 ears corn, cut into thirds
12 ounces smoked sausage, sliced
½ cup unsalted butter, melted
6 cloves garlic, minced
2 tablespoons Old Bay-style seafood seasoning

How to Make Slow Cooker Garlic Butter Shrimp Boil

Step 1: Prepare the Potatoes

Wash the baby potatoes thoroughly.

Cut larger potatoes in half so they cook evenly.

Place the potatoes in the bottom of the slow cooker.

Because potatoes take longer to cook than shrimp and corn, they should go in first.

Step 2: Add the Sausage and Corn

Add the sliced smoked sausage and corn pieces over the potatoes.

Spread everything out as evenly as possible.

The combination of sausage, corn, and potatoes creates the hearty base of this easy Crock Pot seafood boil.

Step 3: Make the Garlic Butter Sauce

In a small bowl, combine:

Melted butter
Minced garlic
Seafood seasoning
Smoked paprika
Black pepper
Onion powder
Red pepper flakes

Stir until well combined.

Reserve a small amount of the garlic butter for serving if desired.

Step 4: Add the Broth

Pour the chicken or seafood broth into the slow cooker.

Drizzle about half of the garlic butter mixture over the potatoes, sausage, and corn.

Add the lemon slices.

Cover and cook on:

LOW for 4–5 hours

HIGH for 2–3 hours

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

Step 5: Add the Shrimp

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

Drizzle the remaining garlic butter mixture over the shrimp.

Gently stir to distribute the seasoning.

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

Shrimp cook much faster than potatoes, so adding them near the end helps prevent overcooking.

Step 6: Finish with Fresh Lemon and Parsley

Remove the lemon slices if desired.

Squeeze fresh lemon juice over the shrimp boil.

Sprinkle generously with chopped fresh parsley.

Taste and add more seafood seasoning or black pepper if needed.

Step 7: Serve

Serve the shrimp boil hot, either directly from the slow cooker or spread onto a large serving platter.

Add extra melted garlic butter and lemon wedges on the side.

What Does a Slow Cooker Shrimp Boil Taste Like?

This Crock Pot shrimp boil is buttery, garlicky, savory, smoky, and slightly spicy.

The potatoes absorb the flavorful broth and seasoning, while the corn adds natural sweetness. Smoked sausage brings a rich savory flavor, and the shrimp provide the star seafood element.

Fresh lemon juice brightens the dish and balances the richness of the garlic butter.

Every bite has a delicious combination of seafood, vegetables, sausage, and buttery seasoning.

The Secret to a Perfect Slow Cooker Shrimp Boil

The most important trick is not to add the shrimp too early.

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

For the best results, make sure the potatoes are nearly tender before adding the shrimp.

Tips for the Best Crock Pot Shrimp Boil

Cut the Potatoes Evenly

Similar-sized pieces cook at the same rate and help prevent some potatoes from becoming overcooked while others remain firm.

Add Shrimp Last

This is the key to tender shrimp.

Use Fresh Garlic

Freshly minced garlic gives the butter sauce a much stronger flavor.

Don’t Overcrowd the Slow Cooker

If possible, use a large slow cooker so the ingredients can cook evenly.

Add Lemon at the End

Fresh lemon juice adds brightness and keeps the dish from tasting too rich.

Can I Use Frozen Shrimp?

Yes. Frozen shrimp can be used, but thaw them completely before adding them to the slow cooker.

Pat them dry before adding them to the garlic butter seasoning.

Can I Use Shell-On Shrimp?

Absolutely. Shell-on shrimp can add extra seafood flavor and are traditional in many seafood boil recipes.

Peeled shrimp are simply easier to eat.

Can I Use Frozen Corn?

Yes. Frozen corn can be substituted for fresh corn.

Add it with the potatoes and sausage and adjust the cooking time as needed.

Easy Variations

Spicy Slow Cooker Shrimp Boil

Add extra red pepper flakes, cayenne pepper, or a spicy seafood seasoning blend.

Cajun Shrimp Boil

Use Cajun seasoning instead of—or alongside—the seafood seasoning for a bolder Southern-inspired flavor.

Garlic Parmesan Shrimp Boil

Add freshly grated Parmesan just before serving for an extra savory finish.

Seafood Crock Pot Boil

Add cooked crab legs or other seafood toward the end of cooking, following appropriate cooking and food-safety guidance for the seafood used.

Vegetable Shrimp Boil

Add sliced bell peppers, onions, green beans, or zucchini for extra vegetables.

What to Serve with Slow Cooker Shrimp Boil

This hearty meal can easily stand on its own, but you can serve it with:

Crusty French bread
Garlic bread
Cornbread
Coleslaw
Green salad
Steamed vegetables
Extra lemon wedges
Homemade garlic butter

Crusty bread is especially useful for soaking up the delicious garlic butter sauce.

How to Store Leftovers

Allow leftovers to cool promptly and transfer them to airtight containers.

Refrigerate within 2 hours and use within 3–4 days.

Reheat gently until everything is heated through.

Because shrimp can become tough when overcooked, avoid prolonged reheating.

Can You Freeze Shrimp Boil?

You can freeze some of the cooked ingredients, but the texture of shrimp and potatoes may change after freezing and thawing.

For the best quality, enjoy this recipe fresh or refrigerated.

Frequently Asked Questions

Can I make this shrimp boil without sausage?

Yes. Simply leave out the sausage and add extra shrimp or vegetables if desired.

Can I use other potatoes?

Absolutely. Baby red potatoes, Yukon Gold potatoes, and small russet potatoes can all work well.

How do I keep the shrimp from getting rubbery?

Add the shrimp near the end of cooking and cook only until opaque and cooked through.

Can I make this recipe spicy?

Yes. Increase the red pepper flakes or use a spicy seafood or Cajun seasoning.

Can I make this in a large Crock Pot?

Yes. A larger slow cooker is ideal when preparing the recipe for a family or gathering.
