Make this classic Cajun shrimp boil in one pot for a flavorful and satisfying Southern seafood feast. This recipe features shrimp, sausage, potatoes, and corn coated in a simple garlic butter sauce, perfect for feeding a crowd with minimal cleanup.

Ingredients

Scale
  • 3 pounds large shrimp, peeled and deveined
  • 1 pound smoked sausage (like Andouille), sliced into 1-inch pieces
  • 2 pounds small red potatoes, halved or quartered
  • 4 ears of corn, cut into 2-inch pieces
  • 1 large yellow onion, quartered
  • 4 cloves garlic, minced
  • 1 cup unsalted butter
  • 1/4 cup Cajun seasoning (use more for extra spice)
  • 1 tablespoon Old Bay seasoning
  • 1 lemon, halved
  • Water, enough to cover ingredients

Instructions

  1. Place the potatoes, onion quarters, and enough water to cover the bottom of a large stockpot into the pot. Bring the water to a boil over high heat.
  2. Once boiling, add the Cajun seasoning and Old Bay seasoning to the water. Stir well to combine the spices into the broth.
  3. Add the sliced sausage to the boiling liquid and cook for 5 minutes.
  4. Add the corn pieces to the pot and cook for another 5 minutes.
  5. Add the shrimp to the pot. Cook until the shrimp turn pink and opaque, about 3 to 5 minutes. Do not overcook the shrimp.
  6. While the shrimp cooks, prepare the sauce: In a small saucepan, melt the butter over medium heat. Add the minced garlic and cook until fragrant, about 1 minute. Remove from heat.
  7. Once the shrimp is cooked, carefully drain most of the cooking liquid from the stockpot, leaving about 1 cup of liquid behind.
  8. Pour the melted garlic butter over the shrimp, sausage, potatoes, and corn. Squeeze the juice from the lemon halves over the mixture. Toss everything gently to coat evenly.
  9. Serve the shrimp boil immediately, traditionally dumped onto a newspaper-lined table or served in large bowls.

Notes

  • For an authentic Low Country Boil feel, serve this meal outdoors and let everyone dig in together.
  • If you prefer a less messy cleanup, you can transfer all ingredients to a large baking sheet after draining the liquid and toss with the butter sauce before serving.
  • Adjust the amount of Cajun seasoning based on your preference for heat.
