Grilled Shrimp Boil Foil Packets
These Grilled Shrimp Boil Foil Packets pack all the bold, buttery flavors of a classic shrimp boil into an easy, mess-free meal perfect for summer grilling. Ready in under 30 minutes with minimal cleanup!
The Ultimate Summer Dinner That Basically Cooks Itself
If you have been searching for the perfect summer meal that delivers massive flavor with almost zero effort, you have found it. These Grilled Shrimp Boil Foil Packets bring everything you love about a classic low-country shrimp boil, tender potatoes, smoky sausage, sweet corn, and buttery seasoned shrimp, and bundle it all up into a tidy little packet that the grill does all the work on. No giant pot. No draining. No mess.
This is the kind of recipe that makes a Tuesday night feel like a backyard party. It is equally perfect for dinner for 2 on the grill (just make two packets) or scaling up to feed a crowd. And because everything cooks sealed in foil, the steam keeps every single ingredient perfectly juicy and infused with that iconic Old Bay butter.
Why This Recipe Belongs in Your Summer Rotation
Let's talk about why foil packet cooking is genuinely one of the smartest small grill recipes you can add to your arsenal.
- Minimal cleanup. Serve the packets right on the plate and toss the foil. Done.
- Everything cooks together. One packet, complete meal.
- Completely customizable. Spicy, mild, extra garlicky, whatever you love.
- Works on the grill OR in the oven. Rain on your cookout? No problem.
This is also one of those secretly healthy recipes that doesn't feel like it. Shrimp is naturally lean and high in protein, and because everything steams in its own juices rather than sitting in a pool of oil, you get huge flavor for a surprisingly reasonable calorie count.
Chef's Tip: The single biggest mistake people make with shrimp on the grill is overcooking. Shrimp cook fast, so 12 to 15 minutes in a sealed foil packet at medium-high heat is all you need. Pull them the moment they turn pink and curl.
The Tools and Ingredients That Actually Matter Here
For foil packet cooking, the quality of your foil and your seasoning make a real difference. Heavy-duty aluminum foil is non-negotiable here; standard foil tears too easily and can let those precious buttery juices escape onto the grill grates. And if you can find a high-quality Old Bay or Cajun seasoning blend you love, it will absolutely elevate the whole dish.
Building the Perfect Shrimp Boil Packet
The secret to a shrimp boil foil packet that tastes like it came from a seaside restaurant comes down to layering your flavors and solving the one classic foil packet problem: vegetables that take longer to cook than protein.
The Par-Cook Trick
Potatoes and corn need more time than shrimp. If you toss everything in raw and seal it up, you will end up with either undercooked potatoes or overcooked rubbery shrimp. The fix is simple: microwave the potatoes and corn for 4 to 5 minutes first. They go into the packet already halfway cooked, so everything finishes at exactly the same moment.
The Butter Situation
Do not skip the butter. Each packet gets a full tablespoon of unsalted butter that melts down over everything as it cooks, blending with the Old Bay and garlic into a savory, slightly spicy sauce that pools at the bottom of the packet. That liquid gold is begging for crusty bread.
Seasoning Generously
Shrimp and potatoes can both handle a bold hand with the seasoning. Two full tablespoons of Old Bay for the whole batch sounds like a lot, but once it distributes across 1.5 pounds of shrimp, a pound of potatoes, sausage, and corn, it lands in exactly the right place. Taste your shrimp before sealing if you want to adjust.
Chef's Tip: Add a few thin lemon slices directly on top of the filling before sealing. As they heat, they release juice that brightens the whole packet and cuts through the richness of the butter beautifully.
Cheap, Cheerful, and Crowd-Ready
One of the best things about this recipe is how approachable it is as a cheap grill meal. Shrimp is one of the more affordable seafood options, especially if you buy frozen and thaw it yourself. A bag of baby potatoes, two ears of corn, and a link of andouille sausage round out the packet for a complete dinner that costs a fraction of what you'd pay for seafood at a restaurant.
For dinner for 2, just make 2 packets and halve the ingredient quantities. Planning a summer cookout? Make 8 packets, pop them all on the grill at once, and dinner is on the table in 15 minutes flat.
These packets work beautifully as summertime meals for camping trips too. Assemble them at home, keep them in a cooler, and cook them straight over the campfire grate.

Grilled Shrimp Boil Foil Packets
These Grilled Shrimp Boil Foil Packets pack all the bold, buttery flavors of a classic shrimp boil into an easy, mess-free meal perfect for summer grilling. Ready in under 30 minutes with minimal cleanup!
Ingredients
- 1 1/2 lbs large shrimp, peeled and deveined, fresh or thawed from frozen, tails on or off
- 1 lb baby red potatoes, halved or quartered if large
- 12 oz smoked andouille sausage, sliced into half-inch rounds
- 2 corn on the cob, husked and cut into 2-inch rounds
- 4 tbsp unsalted butter, divided among packets
- 2 tbsp Old Bay seasoning, or your favorite Cajun blend
- 4 garlic cloves, minced
- 1 lemon, thinly sliced, plus wedges for serving
- 2 tbsp olive oil, for drizzling
- 2 tbsp fresh parsley, chopped, for garnish
- 1/2 tsp crushed red pepper flakes, optional, for heat
- 1/2 tsp salt, to taste
- 1/4 tsp black pepper, freshly cracked
- 4 heavy-duty aluminum foil, large sheets, about 18 inches each
Instruction
Preheat your grill to medium-high heat, around 400 degrees F (200 degrees C). If using the oven, preheat to 425 degrees F (220 degrees C).
Place the halved potatoes and corn rounds in a microwave-safe bowl with a splash of water. Microwave on high for 4 to 5 minutes until just slightly tender but not fully cooked. This ensures everything finishes at the same time on the grill.
In a large bowl, combine the par-cooked potatoes, corn, sliced sausage, and shrimp. Drizzle with olive oil and toss with Old Bay seasoning, minced garlic, red pepper flakes, salt, and black pepper until everything is evenly coated.
Tear off four large sheets of heavy-duty aluminum foil, each about 18 inches long. Divide the shrimp and vegetable mixture evenly among the four sheets, mounding it in the center of each.
Top each mound with 1 tablespoon of butter and 2 to 3 lemon slices.
Fold the long sides of the foil up and over the filling, then fold the short ends in tightly to seal each packet completely. Make sure there are no gaps so steam stays trapped inside.
Place the foil packets on the preheated grill. Cook for 12 to 15 minutes, until the shrimp are pink and opaque and the potatoes are fork-tender. If using the oven, bake for 18 to 20 minutes.
Carefully open each packet away from you, as steam will escape. Garnish with fresh parsley and serve immediately with extra lemon wedges and crusty bread for dipping in the buttery juices.
Equipment
- Gas or charcoal grill (or oven)

Notes
Serving, Storing, and Switching It Up
How to Serve
Open each packet away from you at the table, since the steam is extremely hot. Serve directly in the foil for a true no-dishes experience, or tip everything out into a wide shallow bowl. Have extra lemon wedges, hot sauce, and plenty of crusty bread or rolls on the side for soaking up that incredible seasoned butter.
Variations to Try
- Make it spicier. Double the red pepper flakes or add a diced jalapeño to each packet.
- Go lighter. Swap the andouille for turkey sausage or skip it entirely and add extra shrimp.
- Add more vegetables. Sliced zucchini, bell peppers, or green beans all work well and add color.
- Oven method. Preheat to 425 degrees F and bake on a sheet pan for 18 to 20 minutes for an easy seafood foil packets oven version.
Storing Leftovers
Leftovers keep in an airtight container in the refrigerator for up to 2 days. Reheat on a baking sheet at 350 degrees F for about 8 minutes. The shrimp will be slightly firmer on the second day, so if you are planning ahead, consider saving the shrimp portion and reheating just the sausage and potatoes with freshly cooked shrimp.
