Cut the potatoes into 1-inch chunks and slice the corn into 2-inch rounds. Slice the beef sausage, cut the onion into wedges, mince the garlic, and prepare the lemon wedges and parsley.

Bring a large pot of salted water to a boil. Add the potatoes and corn and cook for 10 minutes until slightly tender. Drain thoroughly and set aside.

Preheat your grill or oven to 400°F (200°C).

Cut four sheets of heavy-duty aluminum foil, approximately 18 inches long each.

In a large mixing bowl, combine the shrimp, beef sausage, onion wedges, garlic, potatoes, and corn.

In a separate bowl, whisk together the melted butter, salt, black pepper, Old Bay seasoning, smoked paprika, and Worcestershire sauce.

Pour the seasoned butter mixture over the shrimp mixture and toss until evenly coated. This helps create the signature flavor of these Spicy Grilled Shrimp in Foil Packets.

Divide the mixture evenly among the four foil sheets, placing everything in the center.

Fold and seal each packet tightly, leaving a little room for steam circulation.

Place the packets on the grill or on a baking sheet in the oven.

Cook for 15 minutes, flipping the packets halfway through cooking.

Carefully open the packets and check that the shrimp are opaque and the potatoes are tender.

Squeeze fresh lemon juice over each packet and sprinkle with chopped parsley.

Serve immediately.
