Save My neighbor showed up at my door one humid July afternoon with a bag of fresh shrimp and that mischievous grin that meant he'd discovered something worth sharing. He'd learned this foil packet method at a beach bonfire the weekend before, and within minutes we were tossing shrimp, sausage, and corn together like we'd been cooking Cajun food our whole lives. There's something about cooking inside foil that feels like opening a gift at the table, and that first waft of steam and spices made me understand why he couldn't wait to tell someone about it.
I made these for a small backyard gathering last summer, and I remember my friend Sarah cutting hers open so carefully, worried about the steam, then closing her eyes for a second when that first smell hit her. She asked for the recipe before she'd even finished eating, which is always the highest compliment. That's when I realized this dish doesn't need anything fancy to feel special, just good ingredients treated simply and a moment to appreciate them.
Ingredients
- Large raw shrimp (1 lb, peeled and deveined): Look for shrimp that smell like the ocean, not ammonia, and ask your fishmonger to devein them if you're squeamish about it.
- Smoked sausage (12 oz, sliced into 1/2-inch rounds): This is the flavor backbone, so don't skip the smoked variety or your whole dish loses that warm, rich character.
- Large onion (cut into wedges): The onion sweetens as it roasts and creates a bed that keeps everything from sticking to the foil.
- Corn (2 ears, each cut into 4 pieces): Fresh corn is worth seeking out, but frozen kernels work beautifully and honestly might be easier to wrangle in a foil packet.
- Baby potatoes (1 lb, halved or quartered): Cut them smaller rather than larger so they actually finish cooking in the time the shrimp needs.
- Garlic (2 cloves, minced): Don't use garlic powder here, fresh garlic becomes sweet and mellow in the steam and it's a completely different thing.
- Olive oil (2 tbsp): This keeps everything from sticking and helps the seasonings coat evenly, so it's not optional.
- Old Bay or Cajun seasoning (2 tsp): Old Bay leans more savory while Cajun seasoning has a bit more heat, so choose based on your mood.
- Smoked paprika (1/2 tsp): This adds a whisper of smokiness that makes people ask what your secret ingredient is.
- Black pepper (1/2 tsp): Fresh cracked is always better, and you can taste the difference.
- Salt (1/2 tsp): Taste as you go because sausage already brings saltiness to the party.
- Lemon (1, sliced): The acid brightens everything at the end and those slices steam right into the packet.
- Fresh parsley (2 tbsp, chopped, optional): A quick sprinkle after opening makes it look intentional and adds a peppery freshness.
Instructions
- Heat your cooking surface:
- Set your oven to 425°F or get your grill to medium-high heat, which takes about 10 minutes and gives you time to prep everything else without rushing.
- Combine everything in a bowl:
- Toss the shrimp, sausage, onion, corn, potatoes, and garlic together so they get to know each other before they steam. This is also when you can check if anything smells off or looks weird.
- Coat with seasonings:
- Drizzle with olive oil first so the seasonings stick instead of just sitting on top, then sprinkle everything on and toss like you mean it. You'll know it's right when you can't see much of the white shrimp anymore because it's all coated in that beautiful golden-orange spice.
- Prepare your foil packets:
- Tear off four sheets of heavy-duty foil, about 12 inches by 16 inches, and lay them out on your counter or a baking sheet. Heavy-duty matters here because regular foil can tear when you're juggling hot packets.
- Divide and arrange:
- Split the mixture evenly among the four packets, piling everything in the center of each foil sheet and then laying lemon slices on top like you're tucking them in. Leave some space around the edges so you can actually fold the foil closed without it being a wrestling match.
- Seal the packets:
- Fold the long sides of the foil up and over the filling, then fold and crimp the short ends tightly so nothing can escape. Imagine you're wrapping a present that has to survive being handled roughly, and you'll get the right idea.
- Cook until ready:
- Arrange packets on a baking sheet if using the oven, or straight on the grill grates if you're braver than me. Bake or grill for 20 to 25 minutes, until the potatoes are fork-tender and the shrimp have turned that opaque pink that means they're done.
- Open carefully and serve:
- Use tongs to move the packets to plates and let people open their own if you want that theatrical moment, or open them yourself in the kitchen and transfer the contents to bowls. Either way, warn them about the steam because nobody enjoys a surprise facial burn.
Save There's a moment when everyone at the table simultaneously opens their packet and that cloud of steam rises up carrying shrimp and garlic and corn butter, and suddenly you're all quiet for just a second before someone says oh wow. That quiet moment is why I keep making this dish, even though it's incredibly simple and honestly kind of silly in its straightforwardness. It doesn't try to be anything more than what it is, and somehow that's exactly enough.
Why This Method Works So Well
Steaming in foil is basically nature's own pressure cooker, where everything sits in its own moisture and seasonings instead of evaporating into your kitchen. The shrimp doesn't dry out because it's not exposed to direct dry heat, and the potatoes soften from both steam and gentle heat rather than getting battered around in a pan. I learned this matters because I once tried this recipe in an open skillet and the shrimp was rubbery while the potatoes were still crunchy, which was a sad Tuesday night dinner.
Customizing Your Packets
The beauty of this recipe is that you can rearrange it like a puzzle based on what's in your kitchen or what you're craving that particular day. Bell peppers are a natural addition, though they might cook slightly faster than potatoes so cut them bigger to balance timing. I've also played around with adding a tiny splash of white wine or even a drop of hot sauce mixed into the oil before tossing, and neither one broke anything.
Serving Suggestions and Final Touches
Crusty bread is non-negotiable here because there will be liquid gold at the bottom of each packet and you'll regret not having something to soak it up with. A simple green salad on the side makes you feel like you've balanced your plate, even though you're mostly just eating seafood and carbs. These packets are best eaten immediately while they're steaming, but leftovers actually reheat pretty well in a low oven if you're feeling practical about it.
- Serve with extra lemon wedges so people can brighten their own flavors to taste.
- Fresh parsley scattered on top right before eating adds a peppery note that nobody expects.
- A cold beer or crisp white wine feels right alongside this dish, though honestly it's not required.
Save This is the kind of recipe that reminds you why cooking together matters, not because it's complicated or impressive, but because it creates moments where simple food becomes a small celebration. Make it for people you like and watch what happens.
