Why You’ll Love This Grilled Shrimp Boil in Foil Packets
Quick 35-Minute Seafood Dinner
This recipe comes together in just 35 minutes from start to finish. First, you prep the potatoes and corn. Then, everything cooks together in one neat foil packet.
Because the shrimp cooks quickly, dinner lands on the table fast. As a result, this meal works well for busy weeknights, summer cookouts, or casual family dinners.
Easy Grill or Oven Method
You can make Grilled Shrimp Boil in Foil Packets on the grill or in the oven. So, even rainy days will not stop you from making this seafood dinner.
The grill adds smoky flavor, while the oven gives steady heat and easy cooking indoors. Either way, the packets trap moisture beautifully.
Big Cajun-Style Flavor with Minimal Cleanup
Old Bay seasoning, garlic, butter, and smoked sausage create bold flavor in every bite. Meanwhile, the foil packets keep all those juices inside.
That means fewer dishes afterward. In fact, cleanup might be the best part besides the shrimp itself.
Ingredients You’ll Need
Shrimp, Sausage, Potatoes, and Corn
You will need:
- 1 pound baby potatoes, cut into 1.5 inch cubes
- 2 ears corn on the cob, sliced into rounds
- 1 pound raw shrimp, peeled and deveined
- 12 ounces Andouille smoked sausage, cut into pieces
The potatoes turn soft and buttery, while the corn adds sweetness. Meanwhile, the sausage gives the dish that smoky Cajun flavor.
Butter, Garlic, Onion, and Old Bay Seasoning
You also need:
- 4 tablespoons melted butter
- 4 garlic cloves, minced
- 1 small yellow onion, sliced
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 tablespoons Old Bay seasoning
The butter mixes with the spices and coats every ingredient. As a result, each bite tastes rich and savory.
Fresh Garnishes for Serving
Fresh parsley and lemon slices brighten the whole meal. So, do not skip them at the end.
The squeeze of lemon cuts through the richness and makes the shrimp pop with flavor.
Best Shrimp to Use for Foil Packets
Peeled and Deveined Raw Shrimp
Raw shrimp works best for Grilled Shrimp Boil in Foil Packets because it cooks right alongside the sausage and vegetables.
Peeled and deveined shrimp also makes eating easier later. Nobody wants to wrestle with shells at dinner time.
Thawed Shrimp for Even Cooking
Always thaw frozen shrimp before cooking. Otherwise, the shrimp may release too much water into the packets.
Thawed shrimp cooks more evenly and keeps the texture tender instead of rubbery.
How to Make Grilled Shrimp Boil in Foil Packets
Preheat the Grill or Oven
First, preheat your grill or oven to 400°F.
Meanwhile, cut four large sheets of heavy-duty foil and set them aside.
Parboil the Potatoes and Corn
Bring salted water to a boil. Then, cook the potatoes and corn for about 10 minutes until slightly tender.
Drain everything well before moving to the next step.
Toss Everything with Butter and Seasonings
In a large bowl, combine:
- Shrimp
- Sausage
- Potatoes
- Corn
- Onion
- Garlic
Next, pour in the melted butter. Add salt, pepper, and Old Bay seasoning. Then toss until evenly coated.
The smell at this stage already feels like a seafood boil party in the kitchen.
Assemble and Seal the Foil Packets
Divide the mixture evenly between the foil sheets.
Next, fold and seal each packet tightly so the steam stays trapped inside during cooking.
Grill or Bake Until the Shrimp Is Tender
Place the packets directly on the grill for about 15 minutes. Flip them halfway through cooking for even heat.
If using the oven, place the packets on a baking sheet and bake for about 15 minutes.
The shrimp should turn pink and tender once fully cooked.
Garnish and Serve with Lemon and Parsley
Carefully open the packets because hot steam escapes quickly.
Then top with chopped parsley and fresh lemon slices before serving.
Grill Method vs Oven Method
How Long to Cook Foil Packets on the Grill
Grilled Shrimp Boil in Foil Packets usually takes about 15 minutes on a 400°F grill.
Flip the packets halfway through so everything cooks evenly. As a result, the potatoes stay tender and the shrimp stays juicy.
How Long to Cook Foil Packets in the Oven
The oven method also takes about 15 minutes at 400°F.
Because the foil traps heat well, the cooking time stays nearly the same indoors or outdoors.
Tips for the Best Shrimp Boil Foil Packets
Use Heavy-Duty Foil
Heavy-duty foil prevents tears and leaks.
That matters because buttery seafood juices can easily escape from thin foil during cooking.
Don’t Overfill the Packets
Leave enough space inside each packet for steam to circulate.
Otherwise, the ingredients may cook unevenly.
Flip Packets Halfway Through Grilling
Flipping helps distribute heat evenly across the packets.
So, the sausage browns better and the potatoes cook more consistently.
Avoid Overcooking the Shrimp
Shrimp cooks very quickly. Therefore, check the packets around the 15 minute mark.
Once the shrimp turns pink and firm, dinner is ready.
Easy Recipe Variations
Swap the Potatoes or Onion
You can use regular potatoes instead of baby potatoes. Just cut them smaller for faster cooking.
White onion or pearl onions also work nicely here.
Add More Seafood
Crab legs, clams, or scallops fit beautifully into these foil packets.

Add Extra Vegetables
Bell peppers, zucchini, or mushrooms bring extra color and flavor.
Meanwhile, extra corn makes the meal even more satisfying.
Adjust the Seasoning Level
Add more Old Bay for stronger Cajun flavor. Or, sprinkle in cayenne pepper if you like heat.

What to Serve with Shrimp Boil Foil Packets
Lemon Wedges and Fresh Parsley
Fresh lemon and parsley keep the meal bright and balanced.
They also make the packets look beautiful right before serving.
Crusty Bread or Dinner Rolls
Warm bread works perfectly for soaking up buttery Cajun juices.
Honestly, nobody wants those flavorful drippings left behind.
Simple Salads and Summer Sides
Light sides balance the richness of the seafood boil.
Try this Fresh street corn salad with Greek yogurt side dish alongside dinner. You can also pair it with Fresh strawberry spinach salad with feta for summer meals.
For another easy shrimp dinner idea, this Quick cilantro lime shrimp tacos for fresh summer dinners always disappears fast at my table.
Make-Ahead Tips
Prep the Ingredients in Advance
Slice the sausage, onions, potatoes, and corn ahead of time.
You can also thaw and clean the shrimp earlier in the day.
Assemble Packets Right Before Cooking
Although prep can happen early, assemble the packets shortly before cooking.
That way, the vegetables stay fresh and crisp.
How to Store and Reheat Leftovers
Refrigerate Leftovers for Up to 2 Days
Store leftovers in an airtight container in the refrigerator for up to 2 days.
The flavors actually deepen a little overnight.
Reheat Gently to Keep Shrimp Tender
Reheat in the microwave using short intervals.
Avoid overheating because shrimp can turn tough quickly.
