Make a flavorful, restaurant-style Cajun Shrimp Boil easily on one sheet pan. This recipe combines juicy shrimp, sausage, corn, and potatoes tossed in a rich garlic butter sauce for a simple, low-cleanup seafood feast.

Ingredients

Scale
  • 2 lbs large shrimp, peeled and deveined
  • 1 lb smoked sausage (like Andouille or Kielbasa), sliced into 1-inch pieces
  • 1 lb small red potatoes, quartered
  • 4 ears of corn, cut into 2-inch pieces
  • 1 medium yellow onion, cut into wedges
  • 1/2 cup unsalted butter
  • 6 cloves garlic, minced
  • 2 tablespoons Cajun seasoning (use more for extra spice)
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 lemon, cut into wedges for serving
  • Fresh parsley, chopped, for garnish

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit. Line a large, rimmed baking sheet with aluminum foil for easy cleanup.
  2. In a large bowl, combine the potatoes, corn pieces, and onion wedges. Drizzle with 1 tablespoon of olive oil (not listed in ingredients, assume basic pantry item) and half of the Cajun seasoning. Toss to coat evenly.
  3. Spread the seasoned vegetables in a single layer on the prepared baking sheet. Roast for 15 minutes.
  4. While the vegetables roast, prepare the garlic butter sauce. In a small saucepan over medium heat, melt the butter. Add the minced garlic and cook for 1 minute until fragrant. Do not let the garlic brown.
  5. Remove the pan from the heat. Stir in the remaining Cajun seasoning, smoked paprika, salt, and pepper into the garlic butter.
  6. Remove the baking sheet from the oven. Push the vegetables to one side of the pan. Add the sliced sausage and shrimp to the empty side of the pan.
  7. Pour about two-thirds of the garlic butter sauce evenly over the shrimp and sausage. Toss gently to coat.
  8. Return the sheet pan to the oven and bake for another 8 to 10 minutes, or until the shrimp is pink and cooked through and the potatoes are tender.
  9. Remove the pan from the oven. Drizzle the remaining garlic butter sauce over everything. Garnish with fresh chopped parsley.
  10. Serve the Sheet Pan Shrimp Boil immediately with lemon wedges on the side.

Notes

  • For a Low Country Boil feel, you can boil the potatoes separately until just tender before adding them to the sheet pan.
  • If you prefer a spicier meal, increase the amount of Cajun seasoning or add 1/2 teaspoon of cayenne pepper to the butter sauce.
  • This recipe works well for feeding a crowd; simply use two sheet pans instead of one.
