These individual foil packets capture all the vibrant flavors of a classic seafood boil in a convenient, mess-free format that's perfect for grilling season. Succulent shrimp mingles with sweet corn kernels, tender baby potatoes, and smoky andouille sausage, all bathed in buttery Old Bay seasoning that creates an irresistible aroma when the packets are opened. The foil steams everything to perfection while keeping cleanup minimal, making this ideal for outdoor gatherings where you want to spend more time with guests and less time in the kitchen.
The first time I made these for a backyard barbecue, I was amazed at how something so simple could create such excitement around the dinner table. Watching everyone carefully unwrap their packets and discover the perfectly steamed contents reminded me why the best summer foods are often the simplest ones. Now these have become our go-to meal for any outdoor gathering because they let me actually enjoy the party instead of being stuck cooking.
Essential Components
- Baby potatoes: Choose small, uniform potatoes about 1.5 inches in diameter for even cooking and tender texture
- Fresh corn on the cob: Select ears with bright green husks and tightly packed kernels, cut into thick rounds
- Large raw shrimp: Peeled and deveined shrimp hold up best to the cooking process and absorb flavors beautifully
- Andouille sausage: Quality smoked sausage provides the essential smoky, spicy base that defines this dish
- Yellow onion: Thinly sliced for sweetness and aroma that mellows during the steaming process
- Fresh garlic: Minced cloves add aromatic depth that permeates every ingredient in the packet
- Real butter: Melted butter helps seasonings coat evenly while adding richness and flavor
- Old Bay seasoning: The classic seafood boil blend of herbs and spices that brings authentic flavor
- Fresh lemons: Bright acidity cuts through richness and adds essential freshness to the finished dish
Detailed Preparation Process
- Grill Preparation:
- Preheat your outdoor grill to 400 degrees Fahrenheit, ensuring the grates are clean and ready. Prepare four sheets of heavy-duty aluminum foil, each approximately 12x12 inches, which will create spacious packets that won't tear during cooking.
- Vegetable Pre-Cooking:
- Bring a large pot of water to a brisk boil and add cut potatoes and corn rounds. Simmer for exactly ten minutes to partially cook these denser vegetables, ensuring they'll be perfectly tender when the packets finish cooking. Drain thoroughly to prevent watery packets.
- Ingredient Assembly:
- Combine the drained potatoes and corn with raw shrimp, sliced sausage, thinly sliced onion, and minced garlic in a large mixing bowl. This thorough mixing ensures even distribution of flavors and prevents any ingredients from clumping together during cooking.
- Seasoning Application:
- Drizzle melted butter evenly over the mixture, followed by salt, freshly ground black pepper, and Old Bay seasoning. Toss everything thoroughly to ensure every piece is coated with the buttery seasoning mixture that will create the signature flavor.
- Packet Formation:
- Divide the seasoned mixture evenly among the four foil sheets, creating generous but manageable portions. Fold the foil tightly around the filling, crimping all edges securely to create steam-tight packets that won't leak during cooking.
- Grilling Process:
- Place sealed packets directly on the hot grill grates and close the lid. Cook for approximately fifteen minutes, flipping the packets halfway through to ensure even heat distribution and proper cooking of all ingredients.
- Final Presentation:
- Carefully open each packet at the table, allowing the aromatic steam to escape dramatically. Top immediately with fresh lemon slices and chopped parsley for color, brightness, and that essential fresh finish that completes the dish.

These satisfying packets have become my favorite way to create a complete, nutritious meal that feels indulgent while providing substantial nourishment. The combination of lean protein from shrimp, complex carbohydrates from vegetables, and healthy fats from butter creates lasting satisfaction that keeps everyone energized. Even my health-conscious friends appreciate how this delivers comfort food satisfaction with genuine nutritional benefits.
Creative Serving Ideas
Serve these packets alongside crusty French bread for soaking up the flavorful juices, or provide small bowls for the aromatic cooking liquid that accumulates. A simple coleslaw or mixed green salad provides cool contrast to the warm, rich contents. For parties, set up a toppings station with hot sauce, extra lemon wedges, and additional herbs for customization.
Flavor Variations
Transform these packets by substituting chicken breast chunks for a different protein profile, or use turkey sausage for lighter options. Sweet potatoes create interesting flavor variations, while different seasoning blends like Cajun spice or Italian herbs offer completely new taste experiences. For spice lovers, add sliced jalapeños or a dash of hot sauce to individual packets.
Storage Solutions
Cool leftover packets completely before transferring contents to airtight containers for refrigerator storage up to three days. Reheat gently in the microwave with a splash of broth or water to restore moisture, or warm in a low oven. These also work well for meal prep, with assembled packets chilling until ready to cook fresh.

This recipe has taught me that some of the most memorable meals come from the simplest preparation methods that allow quality ingredients to shine. The foil packet technique transforms ordinary ingredients into something special through the magic of steam and concentrated flavors. Every time I make these, I'm reminded that the best summer foods are often the ones that bring people together around shared experiences, creating memories that last long after the last bite is finished.
