Filled with shrimp, crawfish, sausage, corn, and potatoes, then seasoned with Cajun seasoning, these easy Cajun Seafood Boil Foil Packets are packed full of flavor and have just the right amount of heat. Best of all, they’re an easy-to-make and easy-to-clean meal!
Seafood boils are one of the hallmarks of a Southern summer. They’re lots of fun, often messy, and always packed full of flavor!
However, a traditional seafood boil calls for cooking the ingredients in a gigantic pot outdoors, then dumping the cooked food out onto a newspaper-covered table for everyone to dig in. It also calls for a lot of ingredients and clean-up.
Wanting to enjoy that same seafood boil flavor on a smaller (and less messy) scale, I found another way to get that amazing taste — foil packets!
Y’all, this grilled Cajun Seafood Boil Foil Packets recipe keeps all the fun and tasty parts of a seafood boil without the need for large amounts of ingredients and a ginormous pot.
It’s incredibly easy-to-make and calls for very little prep and even less clean-up.
Another great thing about these foil packets is that you can make them ahead of time, put them in an airtight container, and refrigerate until you’re ready to grill!
This Cajun Seafood Boil Foil Packets recipe is sure to become a summertime fav!

Seafood Boil Foil Packet Ingredients
Packed with tons of flavor and just the right amount of heat, Cajun Seafood Boil Packets are a full meal in themselves. Each packet contains shrimp, Andouille sausage, crawfish tails, corn on the cob, and baby red potatoes.
What Type of Sausage Should I Use for a Cajun Seafood Boil?
This particular seafood boil recipe calls for using Andouille sausage. However, if you’re looking for an extra spicy Cajun shrimp boil recipe, then using Cajun-spiced sausage works perfectly!
How To Cook Cajun Seafood Boil Packets
Cajun Seafood Boil Foil Packets are typically cooked on a grill, but if it rains or you don’t feel like grilling or you don’t own a grill, you can make this same Cajun Seafood Boil in the oven, too. Either way, you can’t go wrong!
How to Make Cajun Seafood Foil Packets in the Oven
- Preheat oven to 425°F
- Prepare the packets just as you would if grilling them.
- Place packets on a cookie sheet and bake on the center rack 10 – 20 minutes, depending on how done you like your seafood and veggies.
- Serve and enjoy!
How to Cook Seafood Boil Foil Packets on the Grill
- Preheat the grill (if using a gas grill, you’ll want medium-high heat or about 425°F).
- Once the grill is hot, place the seafood foil packets (sealed side up) in the middle of grill.
- Cook 10 – 15 minutes until shrimp are cooked through and potatoes are tender.
- Allow the packets to rest for 2 minutes, then drain the excess juice from the pack.
- Serve and enjoy!
How Do I Avoid Overcooking the Shrimp?
Whichever way you decide to cook these seafood packets, remember that shrimp will cook quickly. To avoid overcooking, place the shrimp on top of the rest of the ingredients before you close the packets. Then, once they’re on the grill, keep an eye on them to ensure they don’t overcook.
How to Store and Reheat Seafood Boil Packets
While these seafood foil packets are best enjoyed the day they’re made, any leftovers can easily be saved for a day or two.
To Store: place any leftovers in an airtight storage container in the refrigerator for up to 2 days.
To Reheat: gently reheat the leftovers in the microwave (not in foil). I personally prefer to keep the shrimp separate as they tend to dry out easily when reheated. So I’ll serve them chilled or at room temperature instead.
Campfire Seafood Boil
This recipe can also be used for campfire cooking! You’ll follow the same instructions as you would if cooking on the grill. Just remember, the potatoes will take longer than the other ingredients, so either pre-boil them a tad or cut them into smaller pieces!
A few more campfire seafood boil foil packets cooking tips include:
- You’ll want to put the packets on the heat for about 15 minutes.
- Remove one of the packets early at about 12-13 minutes to check inside.
- When the potatoes pierce easily with a knife and the shrimp have just turned white, your Cajun Seafood Boil Foil Packets are ready to eat!
- Serve the packets in newspapers and allow each person to carefully open their own.
