Grilling is the way to go for entertaining.  Season your dishes ahead of time and have everything ready to go on the grill for when you’re ready to eat.  I love recipes like this that are easy to entertain without stress like my  Grilled Steak with Bourbon Butter, Coconut Chicken on Skewers and Honey Mustard Pork Chops.  But if you want to cook the whole meal you can also do this easy Grilled Cajun Shrimp Foil Packets recipe.

This recipe is a twist on a Cajun Shrimp Boil recipe.  It’s common in the south to have a bbq and serve a shrimp boil.  When the weather gets hot the last thing I want to do is boil water so I make these make-ahead foil packets to grill for all the juicy flavors without heating up my kitchen in the heat!

Before I share the twist of a shrimp boil I should probably share more about the history of an authentic Cajun Shrimp boil first!

What is a Cajun Shrimp Boil?

A shrimp boil is an easy meal to use to entertain…. you boil all of the ingredients in a cajun spice flavored  broth then when its all done, you scoop out all the delicious creole cajun flavored shrimp, crawfish, potatoes and corn and throw it on to newspaper covered tables.

Nothing fancy but good eating.  The best part?  The clean-up is literally just using the newspapers to roll up all the remnants and tossing it in the trash!

What ingredients are in a shrimp foil packet?

  1. Shrimp or Crawfish
  2. Garlic
  3. Cajun Seasoning Spices
  4. Corn on the Cob
  5. Potatoes
  6. Sausage (usually Andouille)
  7. Onions

PRO TIME SAVING TIP:  Buy shrimp that is already cleaned and deveined to save time.  

In this photo, you can see how the shells are still on, but they have been cleaned.  I find shrimp goes on sale a lot and many times it’s already been cleaned.  Cleaning is easy to do, but it does take time and when I want a shortcut in cooking this is an easy one that doesn’t compromise in taste at all!

Raw uncooked shrimp being prepped for the grill

A few days ago I shared the recipe for homemade cajun seasoning that is perfect for use in shrimp boils.  It also works really well to season this easy make-ahead Cajun Grilled Shimp Foil Packet.  It has the garlic, onion, paprika, thyme, oregano and for some added heat there is cayenne pepper in it.

You’ll use the Creole/Cajun Seasonings in a couple of ways in this recipe.  Peel/clean the shrimp and then use some of the seasoning to marinate the shrimp. Don’t worry you’ll use more seasoning for the rest of the ingredients too, but by marinating the shrimp you’ll get the cajun flavor in every nook and cranny of each shrimp for great flavor in each bite.

Cajun Shrimp marinating to grill

After that, you will want to cut the corn into small manageable pieces.  This helps in two ways in the dish.  It allows for quick cooking on the grill (quick 20-minute meal for the win!) It also gives small bite-sized portions when eating.

Cutting corn to small discs for easy grilling

You’ll want to use very small potatoes for this recipe.  I highly recommend using small red potatoes if you don’t want to cook your potatoes ahead of time before placing them into the foil packet.  If your red potatoes are a little large you can cut them in quarters or halves for the packet.

I tried this recipe with russet potatoes, Yukon gold potatoes and even teeny tiny bite-sized potatoes. All of them were still kind of hard when they came off of the grill.  The red potatoes have just the right amount of starch in them to be able to only cook them in the packet.

TIP FOR SUBBING POTATOES:  Sometimes you can’t find the right potato or you don’t want to go to the store because you have baby fingerlings or russets available instead.  No problem, you can pre-cook them either by parboiling them or doing a quick 4-5 minutes microwave cook on them before you put them in the foil packet.

(HOW TO microwave:  Place bite-sized potatoes in a microwave-safe bowl and fill the bowl with water.  Then drizzle a little olive oil (about a teaspoon) into the water.  Stir the potatoes to have the oil be mixed throughout.  Then drain the water.  The oil will lightly coat the potatoes and a small amount of water will remain.  Cover and microwave on high for 4-5 minutes.  The water helps steam the potatoes and the oil makes it so they will not dry out. )

How do you grill shrimp?

Creating a simple foil packet is the easiest way ever. You’ll want to be sure and use heavy-duty foil or use a double layer of the regular foil.  Place all of the shrimp foil packets into the center of the foil.  Add the peeled shrimp, corn wheels, red potatoes, cajun seasoning and a little bit of butter or olive oil then seal the packet.

Once your grill is hot you’ll place the packets on and grill for 12-15 minutes flipping the packet one time.  At 12 minutes I carefully open one packet being mindful of the steam that will pour out once its opened.  I test one potato and look to make sure the shrimp is done.

Shrimp Boil Foil Packet in the oven

Preheat oven to 425° and cook for 18-20 minutes until shrimp is cooked thru and solid in color.

You can open the packet and serve them right in the foil packet or remove them from the packet and serve it on a plate!  No matter what way you eat it know the shrimp will be succulent and the corn will be cooked perfectly coated with the spicy cajun spices!
