Before you start
Before you begin cooking, gather all your ingredients and prepare your workspace. Wash the cherry tomatoes and fresh parsley, and pat them dry. Peel and devein the shrimp if they are not already prepped, and keep them chilled in the refrigerator until you are ready to assemble.
Slice the smoked sausage into uniform half-inch rounds and cut the corn on the cob into one-inch thick wheels. Melt the butter and mince the garlic so the sauce is ready to be mixed. Finally, preheat your grill or oven to 400°F (204°C) and tear off four large sheets of heavy-duty foil.

Instructions
Preparation and Sauce Mixing
- Prep the Foil and IngredientsSlice the smoked sausage into uniform half-inch rounds and cut the corn on the cob into one-inch thick wheels. Lay out four large sheets of heavy-duty aluminum foil on a flat work surface. Keep the peeled and deveined shrimp chilled in the refrigerator until ready to assemble to ensure food safety.Look for The foil sheets should be large enough to wrap the ingredients completely with room for steam.Tip Using heavy-duty foil is crucial to prevent tearing and leaks during cooking.
- Mix the Garlic Butter SauceIn a small mixing bowl, combine the melted unsalted butter, minced garlic, and Cajun seasoning. Whisk the mixture thoroughly until the spices are evenly distributed throughout the melted butter and the sauce is fragrant.Look for The seasoning should be fully integrated into the butter without clumping.Tip Adjust the Cajun seasoning amount to control the heat level of the final dish.
At the end of this phase, your fresh vegetables and sausage are neatly sliced, the shrimp is cleaned and chilled, and the garlic butter sauce is fully whisked in a bowl, smelling intensely fragrant of garlic and spices. Your foil sheets are laid out flat and ready for assembly.
Assembling and Sealing the Packets
- Assemble the Foil PacketsDivide the chilled shrimp, smoked sausage medallions, corn rounds, and cherry tomatoes equally among the four prepared foil sheets. Arrange them neatly in rows in the center of each sheet to ensure even cooking.Look for The ingredients should be in a single, compact layer in the center of the foil.Tip Keeping the ingredients in rows makes for a beautiful presentation when opened.
- Drizzle and SealDrizzle the garlic butter sauce evenly over the arranged shrimp, sausage, and vegetables in each packet. Fold the long sides of the foil up and over the food, then fold the ends in tightly to create a completely sealed packet.Look for The packets must be sealed tightly to trap the steam inside.Tip Leave a little headspace inside the packet for steam to circulate and cook the food.
At the end of this phase, all four foil packets are fully assembled with neat rows of shrimp, sausage, corn, and tomatoes. The seasoned garlic butter is drizzled evenly over the top, and the foil edges are folded and tightly crimped to form a secure seal.
Cooking and Garnishing
- Grill or Bake the PacketsPlace the foil packets onto a preheated grill over medium-high heat (about 400°F / 204°C) or onto a baking sheet in a preheated oven at 400°F (204°C). Cook for 12 to 15 minutes, until the shrimp are pink and opaque, reaching a safe internal temperature of 145°F (63°C), and the tomatoes begin to burst.Look for The packets will puff up slightly from the steam when they are fully cooked.Safe temperature 145°F (63°C) internal temperature (shellfish)Tip Use tongs to handle the hot packets safely when removing them from the heat.
- Garnish and ServeCarefully open the hot foil packets, peeling the foil back slowly to allow the hot steam to escape safely. Garnish the hot shrimp, sausage, and vegetables with chopped fresh parsley and serve immediately.Look for The shrimp should be cooked through and the butter sauce should be bubbling.Tip Serve directly in the foil packets for a fun presentation and easy cleanup.
At the end of this phase, the foil packets are hot and slightly puffed from the internal steam. When opened, steam billows out, the shrimp are bright pink and opaque, the tomatoes are blistered, and a rich, bubbling garlic butter sauce pools at the bottom, finished with a bright sprinkle of fresh parsley.
Common mistakes
One of the most common mistakes when making foil packets is using standard, thin aluminum foil, which easily rips and lets all the flavorful juices leak out. Always use heavy-duty foil, or double-wrap the packets if you only have standard foil.
Another error is cutting the corn or sausage too thick, which results in unevenly cooked packets where the shrimp overcooks before the corn is tender. Keep the corn slices to one inch and the sausage to half an inch. Lastly, do not seal the packets too loosely; a tight crimp is essential to trap the steam that actually cooks the food.
How to tell it’s done
To ensure your garlic butter shrimp foil packs are perfectly cooked, check that the shrimp have turned completely pink and opaque, forming a loose 'C' shape.
The most reliable way to verify doneness is by inserting an instant-read thermometer into the thickest part of the shrimp; it must register a safe internal temperature of at least 145°F (63°C).
The smoked sausage should be heated through and sizzling, the cherry tomatoes should be soft and blistered, and the corn should be bright yellow and tender when pierced with a fork.
- Shellfish: 145°F (63°C) in the thickest part
