Grilled Shrimp Boil in Foil Packets
This Grilled Shrimp Boil in Foil Packets delivers all the bold, buttery flavors of a classic seafood boil with almost zero cleanup, making it the ultimate summer dinner for two or a crowd.
The Easiest Summer Seafood Dinner You Will Ever Make
If you have been searching for the perfect summer time meal that feels impressive but asks almost nothing of you, you have just found it. These Grilled Shrimp Boil in Foil Packets pack every flavor of a classic Low Country boil into a tidy, self-contained bundle that cooks right on the grill and leaves you with almost zero dishes. Plump shrimp, smoky sausage, sweet corn, and buttery potatoes all tumble together in a garlic-laced Old Bay butter sauce, steaming inside their little foil pouches until everything is perfectly cooked and gloriously saucy.
This is the kind of recipe that wins you compliments at every cookout. It is one of those secretly healthy recipes that feels completely indulgent thanks to bold seasoning, even though it is packed with lean protein and vegetables. Whether you are cooking dinner for 2 on the grill or scaling up for a backyard crowd, these packets are endlessly flexible and practically foolproof.
Getting the right foil and seasoning really does make a difference here. A quality heavy-duty aluminum foil keeps the packets from tearing and trapping all that precious steam, while a generous hand with good Old Bay seasoning is what separates a great shrimp boil from a forgettable one.
Why Foil Packets Are a Summer Game-Changer
Foil packet cooking is one of the most underrated techniques for cheap grill meals that still feel special. Here is why this method works so well:
- Steam-cooking magic. The sealed packet traps heat and moisture, effectively steaming everything from the inside while the grill adds gentle smoky heat from the outside.
- No flare-ups. Because the food never directly touches the grates, you avoid charring and get even, controlled cooking every time.
- Built-in portion control. Each packet is its own serving, making this a natural fit for small grill recipes or intimate dinners for two.
- Zero cleanup. Dinner and the cooking vessel are one and the same. Just toss the foil when you are done.
Think of these packets as your personal little treasure chests. When you tear one open at the table and that cloud of garlicky, lemony steam rises up, the experience is half the fun.
The Secret to Perfectly Cooked Potatoes
The single most important trick in this grilled shrimp boil recipe is par-cooking your potatoes before they go into the packet. Potatoes take significantly longer to cook than shrimp, and if you skip this step you will end up with either rubbery, overcooked seafood or hard, crunchy potatoes.
A quick 4 to 5 minutes in the microwave with a splash of water is all it takes. You are not trying to cook them through, just soften them enough that they finish perfectly in the time it takes the shrimp to turn pink and opaque. It is a tiny extra step that makes the entire dish come together in harmony.
Chef's Tip: Do not skip the resting time after the packets come off the grill. Two full minutes of rest lets the steam settle and the temperature equalize throughout the packet. It also prevents a painful steam burn when you cut them open.
Building the Perfect Flavor Base
The butter sauce that coats everything is where the real flavor lives. A combination of melted butter and olive oil gives you richness without making the sauce feel heavy. The olive oil also raises the smoke point slightly so the butter does not scorch during cooking.
For seasoning, Old Bay is non-negotiable in a classic shrimp boil. It brings a complex blend of celery salt, paprika, and warming spices that is synonymous with seafood on the grill. Add fresh minced garlic and a pinch of red pepper flakes if you like a little heat, and you have a sauce that tastes like it took hours to develop.
The lemon slices laid directly on top of the seafood are not just for looks. As the packet heats, the lemon releases its juice and oils right into the dish, brightening all those rich, buttery flavors.
This recipe fits beautifully into your rotation of perfect summer meals because it genuinely adapts to whatever you have on hand. Swap the andouille for kielbasa, use shrimp of any size, or throw in some sliced bell peppers or zucchini to bulk it up. It is one of those flexible seafood foil packet recipes that rewards creativity.

Grilled Shrimp Boil in Foil Packets
This Grilled Shrimp Boil in Foil Packets delivers all the bold, buttery flavors of a classic seafood boil with almost zero cleanup, making it the ultimate summer dinner for two or a crowd.
Ingredients
- 1 1/2 lb large shrimp, peeled and deveined, tails on
- 1 lb baby red potatoes, halved
- 12 oz smoked andouille sausage, sliced into 0.5-inch rounds
- 2 corn on the cob, husked and cut into thirds
- 4 tbsp unsalted butter, melted
- 2 tbsp olive oil, extra virgin
- 2 tbsp Old Bay seasoning
- 4 garlic, cloves minced
- 1 lemon, thinly sliced, plus wedges for serving
- 2 tbsp fresh parsley, chopped, for garnish
- 1/2 tsp crushed red pepper flakes, optional, for heat
- 1/2 tsp salt
- 1/4 tsp black pepper, freshly cracked
Instruction
Preheat your grill to medium-high heat, about 400 degrees F (200 degrees C).
Place the halved baby potatoes in a microwave-safe bowl with 2 tablespoons of water. Microwave on high for 4 to 5 minutes until just barely fork-tender. This prevents them from being undercooked in the finished packets.
In a large mixing bowl, whisk together the melted butter, olive oil, minced garlic, Old Bay seasoning, red pepper flakes if using, salt, and black pepper.
Add the par-cooked potatoes, corn pieces, sliced sausage, and shrimp to the bowl. Toss everything together until evenly coated in the seasoned butter mixture.
Tear off four large sheets of heavy-duty aluminum foil, each about 18 inches long. Lay them flat on your work surface.
Divide the shrimp and vegetable mixture evenly among the four foil sheets, piling it in the center of each. Lay 2 to 3 lemon slices on top of each portion.
Fold the long sides of the foil up and over the filling to meet in the middle, then fold down in tight pleats to seal. Roll and crimp the short ends tightly so no steam can escape.
Place the foil packets on the preheated grill. Cook for 12 to 15 minutes, flipping the packets once at the halfway point, until the shrimp are pink and opaque and the corn is tender.
Carefully remove the packets from the grill. Let them rest for 2 minutes before opening, as the steam inside will be very hot. Use scissors or tongs to open carefully.
Garnish with fresh chopped parsley and serve immediately with extra lemon wedges and crusty bread for soaking up the juices.

Notes
Serving Ideas and What to Serve Alongside
These packets are a complete meal on their own, but a few simple additions turn dinner into a real spread:
- Crusty sourdough or French bread for mopping up every last drop of that garlic butter sauce
- A simple green salad with a bright vinaigrette to cut through the richness
- Cold beer, lemonade, or a crisp white wine like Sauvignon Blanc
- Extra lemon wedges on the table, always
For a true summer time meal experience, serve the packets right on the table and let everyone tear into their own. Line the table with kraft paper or newspaper for an authentic boil feel and pile on the napkins.
Making It a Dinner for Two
This recipe is incredibly easy to scale down for an intimate dinner for 2 on the grill. Simply halve all the ingredient quantities and make 2 packets instead of 4. The cook time stays exactly the same, making it one of the best small grill recipes when you do not want a mountain of leftovers.
However you serve it, this grilled shrimp boil is the kind of meal that brings people together around the table on a warm evening, and that is really what summer cooking is all about.
