A quick and easy foil packet shrimp boil perfect for campfire or oven cooking, featuring shrimp, potatoes, corn, and a flavorful blend of garlic, lemon, and Cajun spices.

Ingredients

Scale
  • 1 pound medium shrimp, peeled and deveined (fresh or thawed frozen)
  • 1 pound baby potatoes, halved or quartered (Yukon Gold or red potatoes)
  • 2 ears corn on the cob, cut into thirds
  • 4 tablespoons unsalted butter, melted
  • 4 cloves garlic, minced
  • 1 lemon, thinly sliced
  • 1 tablespoon Cajun seasoning
  • 1 teaspoon Old Bay seasoning (optional)
  • 2 tablespoons fresh parsley, chopped
  • Salt and black pepper, to taste
  • Heavy-duty aluminum foil sheets for wrapping

Instructions

  1. Rinse and halve the baby potatoes, cut corn into thirds, peel and devein the shrimp if not prepped. Mince garlic and slice the lemon thinly.
  2. In a large bowl, combine melted butter, minced garlic, Cajun seasoning, Old Bay (if using), salt, and pepper. Stir until blended well.
  3. Add shrimp, potatoes, and corn pieces to the bowl. Toss gently to coat everything evenly with the butter mixture.
  4. Tear off four large sheets of heavy-duty foil (about 12×12 inches each). Divide the shrimp, potatoes, and corn mixture evenly among the sheets. Top each with 2-3 lemon slices and a sprinkle of fresh parsley.
  5. Fold the foil edges tightly to form sealed packets, ensuring no gaps are left open to trap steam.
  6. Place the foil packets on a campfire grill grate or directly on hot coals. Cook for about 15-20 minutes, turning once halfway through. Alternatively, bake on a sheet pan in a preheated oven at 400°F (200°C) for 18-20 minutes.
  7. Carefully open one packet to test doneness. Shrimp should be pink and opaque; potatoes tender when pierced with a fork. If needed, reseal and cook a few more minutes.
  8. Sprinkle with extra fresh parsley before serving. Be cautious of steam when opening packets.

Notes

Use heavy-duty foil or double layer to prevent tears. Do not overcrowd packets to ensure even cooking. Keep fire at medium heat and turn packets halfway through cooking. Parboil larger potatoes for even tenderness. Garlic burns easily if exposed directly to flames, so mix into melted butter. Lemon slices inside packets intensify brightness. Packets can be assembled up to 24 hours ahead and refrigerated before cooking.
