Make a flavorful, low-fuss shrimp boil right on a sheet pan. This recipe combines plump shrimp, sausage, corn, and potatoes, all tossed in a rich Cajun garlic butter sauce for a simple, crowd-pleasing meal.

Ingredients

Scale
  • 2 lbs large shrimp, peeled and deveined
  • 1 lb smoked sausage (like Andouille or Kielbasa), sliced into 1-inch pieces
  • 1.5 lbs small red potatoes, halved or quartered
  • 4 ears of corn, cut into 2-inch pieces
  • 1 medium yellow onion, cut into wedges
  • 1/2 cup unsalted butter
  • 4 cloves garlic, minced
  • 2 tablespoons Cajun seasoning (use your favorite blend)
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon cayenne pepper (adjust for heat)
  • 1/4 cup fresh parsley, chopped (for garnish)
  • 2 lemons, cut into wedges (for serving)

Instructions

  1. Preheat your oven to 400°F (200°C). Line a large, rimmed baking sheet with parchment paper or foil for easy cleanup.
  2. In a large bowl, combine the potatoes, corn pieces, and onion wedges. Drizzle with 1 tablespoon of melted butter and toss with 1 teaspoon of the Cajun seasoning. Spread these vegetables in a single layer on the prepared baking sheet.
  3. Bake the vegetables for 15 minutes to give them a head start on cooking.
  4. While the vegetables bake, prepare the garlic butter sauce. In a small saucepan over low heat, melt the remaining butter. Add the minced garlic, remaining Cajun seasoning, smoked paprika, and cayenne pepper. Stir until the garlic is fragrant, about 1 minute. Remove from heat.
  5. Remove the baking sheet from the oven. Push the partially cooked vegetables to one side of the pan.
  6. Add the sliced sausage and the shrimp to the empty side of the sheet pan. Drizzle about half of the prepared garlic butter sauce over the shrimp and sausage, tossing gently to coat.
  7. Return the sheet pan to the oven and bake for another 8 to 12 minutes, or until the shrimp is pink and cooked through and the potatoes are tender.
  8. Remove the pan from the oven. Drizzle the remaining garlic butter sauce over everything on the sheet pan. Toss gently one last time right on the pan.
  9. Garnish generously with fresh chopped parsley and serve immediately with lemon wedges on the side.

Notes

  • For a true Low Country Boil flavor, add 1 tablespoon of Old Bay seasoning to your main spice mix.
  • If you prefer a spicier kick, increase the cayenne pepper or add a dash of hot sauce to the melted butter mixture.
  • You can substitute the smoked sausage with Andouille sausage for a more authentic Cajun flavor profile.
