Preparation
  1. Preheat your oven to 400°F.

  3. Tear off large sheets of heavy-duty foil, preferably double layers.
  4. Build each packet in this order: potatoes first, then corn, sausage (if using), followed by crab legs and shrimp.
  5. In a bowl, mix melted butter, minced garlic, Cajun seasoning, a squeeze of lemon juice, pepper, and salt.
  6. Spoon the butter mixture over the seafood and veggies in the foil.
  7. Seal the packets tightly and place them on a baking sheet.
Cooking
  1. Bake the packets for about 12 to 15 minutes until shrimp is pink and firm.
  2. If using large crab legs, allow a couple extra minutes while watching the shrimp carefully.

Notes

Serve directly in the opened foil for a fun, casual dining experience. Pair with crusty bread, coleslaw, or a crisp salad. Make ahead of time and refrigerate until ready to cook. Adjust seasoning to taste for spicy or mild options.
