A quick and satisfying grilled shrimp boil cooked in foil packets with shrimp, baby potatoes, corn, and a buttery, garlicky seasoning blend. Perfect for outdoor gatherings and minimal cleanup.

Ingredients

Scale
  • 1 pound large shrimp, peeled and deveined (wild-caught if possible)
  • 1 pound baby potatoes, halved or quartered (red or Yukon gold)
  • 2 ears corn on the cob, cut into thirds
  • 4 cloves garlic, minced
  • 4 tablespoons unsalted butter, melted
  • 2 tablespoons Old Bay seasoning
  • 1 teaspoon smoked paprika
  • Juice of 1 fresh lemon
  • 2 tablespoons fresh parsley, chopped
  • Salt and pepper to taste
  • Optional: sliced andouille sausage or kielbasa
  • Optional: pinch of red pepper flakes

Instructions

  1. Wash and halve the baby potatoes, then parboil them for about 8 minutes until just tender but not falling apart. Drain and let cool slightly.
  2. Cut corn into thirds and peel and devein the shrimp if not done already.
  3. In a bowl, combine melted butter, minced garlic, Old Bay seasoning, smoked paprika, lemon juice, salt, and pepper. Whisk well until evenly distributed.
  4. Tear off four large pieces of heavy-duty aluminum foil (about 12×12 inches each). Divide the potatoes, corn, and shrimp evenly among each piece.
  5. Drizzle the seasoned butter mixture generously over each portion. Add any optional extras like sausage slices or red pepper flakes.
  6. Fold the foil over the ingredients to create a sealed packet. Crimp edges tightly to trap steam inside. Double-layer foil if desired.
  7. Preheat grill to medium-high heat (around 375°F). Place foil packets on grill grates and cook for 6-7 minutes per side, flipping carefully halfway through.
  8. Remove packets from grill and let rest for 2 minutes before opening carefully to avoid hot steam.
  9. Sprinkle chopped fresh parsley on top before serving.

Notes

Parboil potatoes before assembling packets to ensure even cooking. Seal foil packets tightly to trap steam and prevent leaks. Use double layers of foil for extra durability. Avoid overcrowding packets for best results. Optional extras like sausage or red pepper flakes add variety. Can be baked in oven at 400°F for 15-20 minutes if grill is unavailable. Reheat leftovers gently in skillet or oven, avoid microwave.
