Preheat oven to 425°F (220°C), or preheat grill to medium-high heat.
Step 2
In a large bowl, combine shrimp, sausage, onion, corn, potatoes, and garlic.
Step 3
Drizzle with olive oil, then sprinkle with Old Bay or Cajun seasoning, smoked paprika, salt, and black pepper. Toss until everything is evenly coated.
Step 4
Cut 4 large sheets of heavy-duty aluminum foil (about 12x16 inches each).

Divide the mixture evenly among the foil sheets, placing in the center of each. Top each with lemon slices.
Step 6
Fold the long sides of the foil over the mixture, then roll up the ends tightly to seal and create packets.

Zusatztipps für die Zubereitung

To ensure even cooking, cut your baby potatoes into small, uniform pieces so they become tender at the same time the shrimp finishes. Using heavy-duty aluminum foil is essential to prevent any tearing when you are moving the packets on the baking sheet or grill.

Varianten und Anpassungen

For a lighter version, substitute the smoked sausage with chicken sausage or add bell peppers for more color. If you prefer more heat, you can easily customize the seasoning by adding a pinch of cayenne pepper or a few dashes of hot sauce to the mixture before sealing the packets.

Serviervorschläge

Garnish the hot packets with fresh parsley and serve with extra lemon wedges for a bright finish. These packets are excellent when served alongside crusty bread, which is perfect for soaking up the flavorful, seasoned juices from the shrimp and sausage.
