Ingredients for Slow Cooker Shrimp Boil

The beauty of this recipe lies in its classic Southern flavors built from simple, easily available ingredients. Here’s what you’ll need for 4–6 generous servings:

IngredientAmount
Small red potatoes1 1/2 lb, halved if large
Garlic cloves5, lightly crushed
Yellow onion1, quartered
Kosher salt1 1/2 tsp
Dried thyme1/2 tsp
Bay leaf1
Creole seasoning1/4 cup, divided
Lemon1, halved (plus wedges for serving)
Large shrimp, peeled & deveined1 1/2 lb
Andouille sausage12 oz, sliced 1/4″ thick
Fresh corn on the cob2 ears, shucked, cut into thirds
Fresh parsley2 tbsp, chopped
Melted butter & hot sauceFor serving

Ingredient Notes and Tips

  • Shrimp: Large, peeled, and deveined shrimp work best. Buying them fresh is ideal, but high-quality frozen shrimp are a good substitute—just thaw before using.
  • Andouille Sausage: This smoked, spicy sausage is a backbone of Southern seafood boils. Substitute with another smoked sausage if needed.
  • Creole Seasoning: Provides classic Louisiana flavor, a robust blend of paprika, garlic, cayenne, thyme, oregano, and more. Old Bay or Cajun seasoning can be used for a different regional twist. Old Bay is milder and more herb-forward; Cajun blends typically have more heat.
  • Vegetables: Baby red potatoes and fresh corn give a creamy, sweet contrast to the spicy, smoky elements.
  • Lemon: A burst of citrus flavor both cooks with the vegetables and is served fresh at the end.

How to Make Slow Cooker Shrimp Boil

This recipe involves two simple cooking phases—first, simmering the potatoes and aromatics, then adding shrimp, sausage, and corn to finish. Here’s a step-by-step breakdown:

  1. Start with the Potatoes and Aromatics:
    Combine potatoes, garlic, onion, salt, dried thyme, bay leaf, and 2 tablespoons of the Creole seasoning in the slow cooker. Add 4 cups water, then squeeze in the juice from the halved lemon, adding the lemon halves as well. Cover and cook on low for 3 1/2 to 4 hours, or until potatoes are fork-tender.
  2. Add Protein and Corn:
    Once the potatoes are tender, add the shrimp, sliced andouille sausage, corn pieces, and the remaining Creole seasoning. Stir gently. Cover and cook on high for 30 minutes—the shrimp will become pink and firm, and the sausage will infuse its flavor throughout.
  3. Finishing Touches:
    Discard the bay leaf and lemon halves. Sprinkle chopped parsley over the mixture. Use a slotted spoon to transfer the shrimp, potatoes, sausage, and corn into bowls or onto a platter.
  4. Serve:
    Accompany with plenty of melted butter, lemon wedges, and hot sauce. Optionally, serve it right on a paper-lined table for that authentic boil experience!

Serving Suggestions and Pairings

A shrimp boil is all about the feast and fun. Serve your slow cooker shrimp boil with simple rustic sides to complement its bold flavors:

  • No-Knead Dinner Rolls: Perfect for soaking up the spicy, buttery broth.
  • Crispy Jalapeño Cornbread: Adds texture and echoes the meal’s Southern spirit.
  • Ranch Slaw or Cabbage Slaw: A fresh, creamy counterpoint to the spices and heat.
  • Cold Drinks: Sweet iced tea, lemonade, or ice-cold beer keep things cool and festive.

Tips for the Best Slow Cooker Shrimp Boil

  • Don’t Overcook the Shrimp: Shrimp cook quickly and become rubbery if overdone. Once added, keep an eye on the time—they need just 30 minutes.
  • Use the Largest Shrimp You Can Find: Bigger shrimp perform better in a slow cooker, remaining juicy and tender.
  • Shell-On vs Shelled Shrimp: Shell-on shrimp deliver more flavor but are messier to peel; shelled shrimp are easier to eat. Choose based on your guests’ preferences.
  • Customize the Heat: Adjust the Creole or Cajun seasoning to your crowd’s spice tolerance, and offer hot sauce on the side for extra kick.
  • Add More Seafood: For a special occasion, include crab, clams, or mussels in the last 30 minutes with the shrimp and sausage.

Frequently Asked Questions (FAQ)

Can I use frozen shrimp?

Yes, you can use frozen shrimp, but thaw them completely first and pat dry, so they cook evenly and don’t water down the slow cooker liquid.

What’s the difference between Creole and Cajun seasoning?

Creole seasoning is more herbaceous, typically including dried herbs like thyme and basil, while Cajun seasoning emphasizes heat from cayenne and chili peppers and is less focused on herbs. Old Bay is another alternative with its own unique flavor and less heat.

How do I make this recipe spicier or milder?

Increase or reduce the amount of Creole/Cajun seasoning for more or less spice. Always serve with extra hot sauce for those who want added heat.

Can I prepare this ahead of time?

You can prep all the veggies and sausage in advance, but wait to add shrimp until the final 30 minutes of cooking. Leftovers keep well in the refrigerator for up to 2 days—reheat gently to avoid overcooking the shrimp.

How should I serve a shrimp boil?

Traditionally, boil ingredients are heaped straight onto a paper or newspaper-lined table for communal feasting. For easy cleanup, line the table with parchment or butcher paper instead of newspaper. Ladle servings into big bowls for a less messy, more weeknight-friendly presentation.

Recipe Variations and Add-Ons

  • Other Seafood: Add clams, crab legs, or mussels during the last 30 minutes for a mixed seafood feast.
  • Vegetarian Twist: Skip the sausage and shrimp and double up on potatoes, corn, mushrooms, and zucchini. Use smoked paprika for depth.
  • Change Up the Sausage: Substitute kielbasa, chorizo, or any favorite smoked sausage for a new flavor profile.
  • Make it Low-FODMAP or Allergy-Friendly: Use garlic-infused oil in place of garlic cloves and avoid seasoning blends containing allergens.

Storing and Reheating Leftovers

Leftover shrimp boil keeps for up to 2 days in the refrigerator. Store the broth and solids separately, if possible. Reheat gently in the microwave or on the stovetop, being careful not to overcook the shrimp.

Nutrition Highlights

This dish is packed with protein (from shrimp and sausage) and dietary fiber (from corn and potatoes). Adjust the amount of sausage and butter to make it lighter or richer as desired. For a gluten-free meal, verify that your sausage and seasoning are gluten-free.
