  • 4 tbsp salted butter melted
  • 3 tsp Cajun seasoning
  • 1 tsp Old Bay seasoning
  • 3 tbsp lemon juice
  • 1 1/2 lbs shrimp peeled and deveined
  • 1 lb crawfish
  • 1 lb Cajun sausage cut into 1 inch pieces
  • 2 ears of corn sliced into 2 inch disks
  • 2 cups baby potatoes halved
  • 4 grilling foil cut into 12X12" squares


  • 3 tbsp parsley finely chopped
  • lemon wedges


  1. Place the grill on medium high (at least 350 degrees). Add the melted butter, Cajun seasoning, Old Bay seasoning, and lemon juice in a small bowl. Whisk to combine.

    Melted butter, lemon juice, and Cajun seasoning is combined in a small bowl before it's tossed with shrimp.
  2. Add the shrimp, crawfish, sausage, corn, and baby potatoes to a bowl, then drizzle the melted butter mixture over it. Toss everything together with a large spoon until everything is well coated.

    The shrimp, crawfish, corn, potatoes, butter, and seasoning are tossed together in a bowl to evenly coat everything.
  3. Cut the grilling foil into 4 12X12" squares. Place 2 cups of the shrimp mixture in the center of the grilling foil.

    Shrimp, crawfish, sausage, corn, and potatoes are placed on the grilling foil before they are wrapped.
  4. Grab two parallel edges of the foil and clamp it to seal the edges. Grad the unsealed edges and roll them until it meets the shrimp mixture in the center. Do this to the other unsealed edge.

    The grilling foil is sealed to cook the shrimp mixture.
  5. Place the foil packets on the grill and cook for 15 minutes. Flip the packets and continue cooking for 7 more minutes. Remove the packets from the grill, then uncover and top with parsley and wedges of lemon. Mangia!

    The shrimp foil packet is cooked and unwrapped and ready to eat.
