Cajun Crockpot Shrimp Boil

Here is my favorite crockpot shrimp boil recipe, with tender potatoes, smoky andouille sausage, sweet corn, and perfectly cooked shrimp all simmered together in a flavorful Old Bay broth.

This shrimp boil is one of those meals that feels like a party on a plate, but couldn’t be easier to make. Just toss everything in the slow cooker and let it do all the work while you go about your day. My family loves spreading it all out on a big table with plenty of napkins and melted butter for dipping!

What Kind of Shrimp Should I Use?

For a crockpot shrimp boil, you’ll want to use raw shrimp rather than pre-cooked, since they’ll be simmering in the slow cooker and need that cooking time to soak up all the seasoning. Size-wise, large or jumbo shrimp (around 21-30 count per pound) work best because they won’t overcook as easily and are more satisfying to eat. You can buy shrimp with the shells on or off – shell-on will give you more flavor, but peeled and deveined shrimp are way more convenient and still taste great. Fresh shrimp is ideal if you live near the coast, but frozen shrimp works just as well for this recipe and is often fresher since it’s frozen right after being caught.

Options for Substitutions

This shrimp boil is pretty forgiving when it comes to swaps, so here are some options:

• Andouille sausage: If you can’t find Andouille, kielbasa or any smoked sausage works great. For a spicier kick, try chorizo, but go easy on the hot sauce since it’s already pretty spicy.
• Old Bay seasoning: This is really the star of the show, so try not to substitute it. But if you’re in a bind, you can make a quick mix with paprika, celery salt, black pepper, and cayenne pepper – though it won’t be quite the same.
• Red potatoes: Yukon gold or baby potatoes work just as well. You can even use sweet potatoes for a slightly different flavor, though they’ll cook a bit faster.
• Fresh corn: Frozen corn on the cob works in a pinch. Just add it during the last 15 minutes of cooking since it’s already partially cooked.
• Hot sauce: Any hot sauce you like will do – Tabasco, Louisiana, or Crystal all work. Adjust the amount based on your heat preference.
• Shrimp: Make sure to use raw shrimp for this recipe, not pre-cooked. If your shrimp still has tails on, that’s fine – some people actually prefer it that way for easier handling.

Watch Out for These Mistakes While Cooking

The biggest mistake you can make with this recipe is adding the shrimp too early, which will turn them rubbery and overcooked – they only need about 15 minutes once the liquid is hot, so wait until the very end when your potatoes are tender. Another common error is not draining enough liquid before serving, leaving you with a watery mess instead of a proper boil, so make sure to remove most of the cooking liquid while keeping just enough to keep everything moist. To get the best flavor, don’t skip the step of letting your potatoes cook for the full 2 hours before adding the sausage and corn, as this gives them time to absorb all those spices from the Old Bay and hot sauce. Finally, if your shrimp are different sizes, the smaller ones will cook faster than the larger ones, so try to use similarly-sized shrimp or add the larger ones first and the smaller ones a few minutes later.

What to Serve With Shrimp Boil?

A shrimp boil is pretty much a complete meal on its own since you’ve got potatoes, corn, sausage, and shrimp all in one pot, but I love adding a few simple sides to round things out. Crusty French bread or dinner rolls are perfect for soaking up all that seasoned broth and melted butter – trust me, you don’t want any of those flavors going to waste. A simple coleslaw with a tangy vinegar-based dressing cuts through the richness of the dish and adds a nice crunch. If you want to keep the Southern theme going, consider adding some hush puppies or a light cucumber and tomato salad on the side.

Storage Instructions

Store: Keep your leftover shrimp boil in an airtight container in the fridge for up to 3 days. I like to store the shrimp separate from the potatoes and corn if possible, since seafood is best eaten sooner rather than later. The sausage and veggies will actually taste even better the next day after soaking up all those flavors!

Reheat: Warm up your leftovers gently in a pot on the stove with a splash of water or broth to keep everything moist. You can also microwave individual portions for about 2 minutes, stirring halfway through. Just be careful not to overcook the shrimp or it’ll get rubbery.

Freeze: I don’t recommend freezing this one since shrimp and potatoes don’t hold up well in the freezer. The shrimp can get mushy and the potatoes tend to get grainy when thawed. It’s best to enjoy this fresh or within a few days from the fridge.

• Calories: 2100-2300

• Carbohydrates: 230-250 g

Ingredients

For the base:

• 1.5 lb red potatoes (halved or quartered into 1.5-inch chunks)
• 1 head garlic, cloves lightly smashed
• 2 bay leaves
• 6 cups water
• 1/3 cup old bay seasoning
• 1.5 tbsp hot sauce
• 1.5 tbsp lemon juice
• 1 tsp onion powder
• 1 tbsp Worcestershire sauce

For the boil additions:

• 1 lb andouille sausage (sliced into 1-inch thick rounds)
• 4 ears corn (shucked and sliced into thirds)

For finishing:

• 2 lb raw shrimp (peeled and deveined but tail-on for better presentation)
• 6 tbsp butter (melted)
• 4 tbsp parsley (freshly minced)
• 2 lemons (cut into wedges for serving)

Step 1: Build the Flavorful Broth Base

• 1.5 lb red potatoes
• 1 head garlic, cloves lightly smashed
• 2 bay leaves
• 6 cups water
• 1/3 cup old bay seasoning
• 1.5 tbsp hot sauce
• 1.5 tbsp lemon juice
• 1 tsp onion powder
• 1 tbsp Worcestershire sauce

Add the potatoes, smashed garlic cloves, and bay leaves to your crockpot.

Pour in the water and stir in the Old Bay seasoning, hot sauce, lemon juice, onion powder, and Worcestershire sauce until the seasonings are dissolved.

This creates a deeply seasoned broth that will infuse all the ingredients with flavor as everything cooks together.

Step 2: Cook Potatoes Until Tender

• broth mixture from Step 1

Cover the crockpot and cook on high for 2 hours.

The potatoes need time to become tender enough to absorb the seasoned broth—this foundation is crucial because potatoes take the longest to cook of all the ingredients.

I find that checking them around the 1.5-hour mark helps you gauge exactly when they’re fork-tender.

Step 3: Add Sausage and Corn

• 1 lb andouille sausage
• 4 ears corn
• cooked potato mixture from Step 2

After 2 hours, stir in the sliced andouille sausage and corn thirds.

These ingredients cook faster than potatoes but need time to heat through and allow their flavors to meld with the broth.

Cook on high for 2 to 3 hours, stirring occasionally, until the potatoes are completely soft and the sausage is heated through.

Step 4: Cook Shrimp Until Just Pink

• 2 lb raw shrimp
• cooked sausage and vegetable mixture from Step 3

Add the peeled and deveined shrimp to the crockpot and stir gently to distribute them throughout the broth.

Cook on high for 15 minutes—this is the critical window where shrimp transforms from translucent to opaque and pink.

I always set a timer for this step because overcooked shrimp becomes rubbery, so those 15 minutes are all you need.

Step 5: Finish and Serve

• 6 tbsp butter
• 4 tbsp parsley
• 2 lemons
• cooked shrimp and vegetable mixture from Step 4

Using a slotted spoon, transfer the potatoes, sausage, corn, and shrimp to a serving platter or large bowl, leaving most of the broth behind in the crockpot.

Drizzle the melted butter over the top and sprinkle generously with fresh minced parsley.

Serve immediately with lemon wedges on the side for guests to squeeze over their portions as desired.
