Create a flavorful, low-effort seafood feast using this sheet pan shrimp boil recipe. Shrimp, sausage, corn, and potatoes bake together, coated in a rich Cajun garlic butter sauce for minimal cleanup.

Ingredients

Scale
  • 1.5 lbs large shrimp, peeled and deveined
  • 1 lb smoked sausage (like Andouille or Kielbasa), sliced into 1-inch pieces
  • 1 lb small red potatoes, halved or quartered
  • 3 ears of corn, cut into 2-inch pieces
  • 1 large yellow onion, cut into wedges
  • 1/2 cup unsalted butter
  • 4 cloves garlic, minced
  • 2 tablespoons Cajun seasoning (use a high-CPC Cajun seafood boil blend)
  • 1 tablespoon Old Bay seasoning
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon cayenne pepper (adjust for spice level)
  • 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 aluminum foil for easy cleanup.
  2. In a large bowl, combine the potatoes, sausage, corn pieces, and onion wedges.
  3. In a small saucepan over low heat, melt the butter. Add the minced garlic, Cajun seasoning, Old Bay seasoning, smoked paprika, and cayenne pepper. Stir until the butter is fully melted and the spices are fragrant, about 2 minutes. This creates your seafood boil sauce recipe base.
  4. Pour half of the garlic butter sauce over the potato, sausage, corn, and onion mixture. Toss everything well to coat evenly. Spread the mixture in a single layer on the prepared sheet pan.
  5. Bake for 15 minutes.
  6. While the vegetables bake, place the peeled shrimp in the same bowl used earlier. Pour the remaining half of the garlic butter sauce over the shrimp and toss gently to coat.
  7. Remove the sheet pan from the oven. Push the vegetables to the sides and arrange the seasoned shrimp in the center of the pan in a single layer.
  8. Return the sheet pan to the oven and bake for another 8 to 10 minutes, or until the shrimp are pink and cooked through and the potatoes are tender.
  9. Remove from the oven. Sprinkle the entire sheet pan with fresh chopped parsley. Serve immediately with lemon wedges for squeezing over your easy shrimp dinner ideas.

Notes

  • For a true Low Country boil flavor profile, add 1 teaspoon of dry mustard powder to your butter sauce.
  • If you prefer a mess-free shrimp boil experience, you can assemble all ingredients (except shrimp) on the pan, bake for 15 minutes, then add the shrimp, top with foil, and bake for the final 10 minutes.
  • This recipe works well as a crawfish boil alternative when shrimp is the main focus.
