A quick and flavorful Cajun shrimp boil cooked in foil packets, perfect for fuss-free summer meals with shrimp, sausage, corn, and potatoes infused with spicy, buttery goodness.

Ingredients

Scale
  • 1 pound large shrimp, peeled and deveined (fresh or thawed frozen)
  • 8 ounces andouille sausage, sliced
  • 1 pound baby potatoes, halved or quartered
  • 2 ears corn on the cob, cut into thirds
  • 2 tablespoons Cajun seasoning
  • 3 cloves garlic, minced
  • 4 tablespoons unsalted butter, softened
  • 1 lemon, sliced
  • A handful fresh parsley, chopped (optional)
  • Salt and pepper to taste

Instructions

  1. Preheat your grill to medium-high heat (about 400°F) or preheat your oven to 400°F (205°C).
  2. Rinse and halve the baby potatoes, cut the corn into thirds, slice the sausage, and peel and devein the shrimp if needed. Mince the garlic and slice the lemon.
  3. In a mixing bowl, combine softened butter, Cajun seasoning, minced garlic, salt, and pepper. Stir until well blended.
  4. Add the potatoes, corn, sausage, and shrimp to the bowl with the seasoning butter. Toss gently but thoroughly to coat evenly.
  5. Tear off four large sheets of heavy-duty aluminum foil (about 12×12 inches). Divide the mixture evenly among the sheets, spreading it out but leaving some space at the edges. Place a couple of lemon slices on top of each packet.
  6. Fold the foil over the ingredients and crimp the edges tightly to seal the packets, ensuring no gaps for steam to escape.
  7. Place the foil packets on the grill grates or on a baking sheet in the oven. Cook for 15-18 minutes, or until shrimp turn pink and opaque, potatoes are tender, and sausage is heated through.
  8. Carefully remove the packets using tongs or heat-resistant gloves. Let cool for a minute before peeling back the foil to avoid hot steam.
  9. Garnish with fresh parsley if desired and serve immediately.

Notes

Do not overcook shrimp to avoid rubbery texture; watch for pink color and curling. Seal foil packets tightly to trap steam and keep food moist. Potatoes can be parboiled for 5 minutes to speed cooking. For more smoky flavor, add liquid smoke to seasoning butter or cook packets above coals. Can be prepared ahead and refrigerated before cooking. Avoid microwaving leftovers to prevent rubbery shrimp.
