30-Minute Shrimp Boil Foil Packets (Grill or Oven)

These shrimp boil foil packets pack all the flavor of a classic low country boil—sweet corn, tender potatoes, smoky sausage, and juicy shrimp—into a tidy, no-mess dinner. Everything steams inside its own pouch so the seasonings coat every bite, and cleanup takes about thirty seconds.

It’s a full meal that tastes like summer, and you can cook it on the grill or in the oven with the same straightforward method. The shrimp stay plump, the potatoes get creamy, and the butter and Old Bay turn into a spiced, garlicky sauce right in the packet.

Why These Shrimp Boil Packets Work

The enclosed foil pouch traps steam so the shrimp cook gently and never turn rubbery. Butter, lemon, Old Bay, and garlic melt together into a thin, savory sauce that clings to every ingredient, from the sweet corn to the halved baby potatoes.

You can assemble the packets ahead, toss them on the grill after work, and serve everyone straight from the foil. No pot, no colander, no standing over a hot stove. Just open and eat.

Ingredients

• 1 lb large shrimp, peeled and deveined: tail on or off is fine; use fresh or thawed frozen shrimp
• 2 ears corn, cut into thirds: fresh sweet corn works best
• 8 oz baby potatoes, halved: quarter them if they are larger than a walnut
• 6 oz andouille sausage, sliced into 1/2-inch rounds: smoked sausage or kielbasa works too
• 4 tbsp unsalted butter, melted
• 1 tbsp Old Bay seasoning
• 3 cloves garlic, minced
• 1 lemon: half juiced, the other half cut into wedges for serving
• Salt and black pepper
• Fresh parsley, chopped: for a quick finish

Variations and Swaps

• Swap the protein: Boneless chicken thighs cut into 1-inch chunks work well; add 2 extra minutes of cook time to reach 165°F.
• Add more vegetables: Zucchini coins, bell pepper strips, or halved mushrooms can be tossed right in with the shrimp mixture.
• Change the spice: Use Cajun seasoning instead of Old Bay for more heat, or add a pinch of cayenne.
• No andouille: Any smoked sausage, kielbasa, or even chorizo will give you the same savory backbone.
• Dairy-free: Swap the butter for olive oil or a dairy-free buttery spread.

How to Make Shrimp Boil Foil Packets

Step 1: Toss the Shrimp and Veggies in Butter and Seasoning

Preheat your grill to medium-high heat, about 400°F, or set the oven to 425°F (220°C). In a large bowl, combine the 1 lb shrimp, the 2 ears of corn (cut into thirds), the 8 oz halved baby potatoes, and the 6 oz sliced andouille sausage. Drizzle the 4 tbsp melted butter and the juice from half the lemon over the top, then sprinkle in the 1 tbsp Old Bay, the 3 minced garlic cloves, and a pinch of salt and pepper.

Toss everything with your hands or a big spoon until every piece is shiny with butter and flecked with seasoning. The Old Bay will hit your nose right away, and that’s a good sign it’s well mixed. The corn and sausage will give off a slight sticky gloss from the butter.

Step 2: Pile the Mixture onto Foil

Lay out four 12-inch squares of heavy-duty aluminum foil. Divide the seasoned shrimp mixture evenly among them, piling it right in the center of each square. Try to keep a bit of space around the edges so you can seal the packets without tearing.

The pile will look generous, with pink shrimp tails peeking through the golden corn and dark sausage rounds. If a few potato halves roll to the side, just nudge them back into the center. The dry seasoning that’s stuck to the bowl can be scraped over the top.

Step 3: Grill the Foil Packets

Bring the long edges of each foil square together and fold them down twice to create a tight seal. Then fold in the short ends, pinching firmly so no steam escapes. Place the sealed packets directly on the grill grates over direct heat, or set them on a baking sheet if you’re using the oven. Cook for 12 to 15 minutes on the grill (about 15 to 18 minutes in the oven), until you can hear the packets sizzle and smell the butter and sausage.

The foil will puff up slightly as the steam builds inside. Avoid opening one too early; that sudden release can cook off the liquid that keeps the shrimp tender. If you’re unsure after 12 minutes, carefully poke a tiny vent with a knife and peek inside—the shrimp should be opaque and the potatoes easily pierced with a fork.

Step 4: Open and Serve the Shrimp Boil Packets

Carefully transfer each packet to a plate or shallow bowl. Use a knife to split the foil open right at the table so the steam billows up. The lemon wedges, a sprinkle of chopped fresh parsley, and a final crack of black pepper make it feel complete.

Eat them right out of the foil while the butter sauce is still bubbling around the edges. The corn will be tender and sweet, the sausage a little crisp on the edges, and the shrimp perfectly plump.

A Few Things That Help

• Cut the potatoes small, no bigger than a walnut half, so they finish at the same time as the shrimp. A quick parboil of 3 minutes can help if your potatoes are stubborn.
• If your grill has hot spots, double-wrap each packet with a second layer of foil to prevent the bottom from scorching before the center cooks through.
• Don’t crowd the packets. Leave room around the pile for steam to move, otherwise the shrimp can steam unevenly.
• Check one packet a minute early. Shrimp go from tender to overdone fast, and you can always reseal and return it to the heat.

Cook times by method:

Storing Leftovers

Refrigerate any leftovers in an airtight container for up to 2 days. Reheat gently in a skillet over medium-low heat with a splash of water or broth so the shrimp stay moist. Microwaving works in a pinch, but the shrimp can tighten up quickly.

Frequently Asked Questions

Can I use frozen shrimp?

Yes, thaw them completely first and pat them very dry. Excess water will make the packets steam more and you’ll end up with a thinner, less flavorful sauce.

Can I make these foil packets ahead of time?

Assemble the packets and refrigerate for up to 8 hours before cooking. If you cook them straight from the fridge, add 2 extra minutes of cook time.

What can I substitute for Old Bay?

Mix equal parts celery salt and paprika, then add a pinch of black pepper and cayenne. Cajun seasoning is another solid stand-in.

My potatoes weren’t fully tender—what went wrong?

They were likely too large or the heat wasn’t high enough. Cut them smaller next time, and keep the grill or oven at the temperature called for so the steam builds quickly.

Can I add clams or mussels?

Yes, tuck a few into each packet during the last 3 minutes of cook time. Seal the packet again right away so the trapped steam opens them up.

Ingredients Method Notes

Ingredients

  

• 1 lb large shrimp, peeled and deveined
• 2 ears corn, cut into thirds
• 8 oz baby potatoes, halved
• 6 oz andouille sausage, sliced into 1/2-inch rounds
• 4 tbsp unsalted butter, melted
• 1 tbsp Old Bay seasoning
• 3 cloves garlic, minced
• 1 lemon, half juiced and half cut into wedges
• Salt and black pepper
• Fresh parsley, chopped

Method

 

1. Toss the shrimp, corn, potatoes, and sausage with the melted butter, lemon juice, Old Bay, garlic, salt, and pepper in a large bowl.
2. Divide the mixture evenly among four 12-inch foil squares, piling it in the center with space around the edges.
3. Seal the packets by folding the long edges twice and pinching the short ends, then grill over medium-high heat for 12–15 minutes or bake at 425°F for 15–18 minutes.
4. Open the packets carefully at the table, scatter parsley and lemon wedges over the top, and serve while the butter sauce is bubbling.

Notes

If you’re using the oven, the bottom of the packets may brown a little, and that’s completely fine. Serving directly from the foil keeps the casual feel and holds every drop of the sauce right where you want it.
