Ingredients You’ll Need

With just the basics and a handful of vibrant spices, every ingredient here plays a starring role in delivering that signature shrimp boil flavor. Don’t be tempted to skip or substitute too much — each piece adds something special to the taste, texture, or color of your Cajun Shrimp Boil in Foil.

• Corn on the Cob: Fresh, sweet corn adds juicy pops of flavor and soaks up all those Cajun spices beautifully. Cut it into smaller pieces for quicker cooking.
• Andouille Sausage: This spicy, smoky sausage brings a rich, savory layer to the boil, but any smoked sausage will work in a pinch.
• Argentinian Shrimp: Known for their butteriness and snap, these shrimp are the real stars — just be sure to peel and devein them.
• Baby Potatoes: Creamy, tender potatoes provide heartiness and balance; halve or pre-boil them for perfect timing with the rest of the ingredients.
• Paprika: Adds color and a gentle smokiness that’s a hallmark of Cajun flavor.
• Salt: Essential for bringing all the flavors forward.
• Pepper: A touch of heat and complexity in every bite.
• Garlic Powder: For that robust, aromatic backbone.
• Onion Powder: Rounds out the savoriness of the seasoning blend.
• Oregano: Herbs in Cajun dishes lend earthiness and depth — don’t skip it.
• Thyme: Another herbal note that brings Southern comfort to the boil.
• Cayenne Pepper: Optional but highly recommended for a true Cajun kick — add more or less depending on your heat preference.

How to Make Cajun Shrimp Boil in Foil

Step 1: Prep Your Vegetables and Protein

This first step is all about ensuring everything cooks evenly. Slice your andouille sausage into thick coins on a slight angle for maximum browning. Cut the corn into smaller rounds and halve or quarter your baby potatoes. If you’re short on time, parboil the potatoes and corn for a few minutes so they’re ready when the shrimp and sausage are done. Peel, devein, and wash your shrimp, making sure to remove the tails for the ultimate bite-sized experience.

Step 2: Mix Everything Together

Grab your biggest mixing bowl and toss in the corn, potatoes, sausage, and shrimp. Drizzle everything with a bit of oil, then sprinkle generously with all your seasonings: paprika, salt, pepper, garlic and onion powders, oregano, thyme, and that optional cayenne. Use your hands or a big spoon to mix until every piece is glistening with delicious spice.

Step 3: Assemble the Foil Packets

Lay out four large rectangles of heavy-duty aluminum foil (about 12 inches each). Evenly divide your Cajun Shrimp Boil mixture among the packs, piling it into the center. Now, bring the longer sides together and fold them over to seal, then fold in the short ends to make a little packet. Make sure everything’s snug inside so you trap all those flavors.

Step 4: Cook to Perfection

Cooking times vary based on your method. For a campfire: nestle the foil packets in the hot coals (not direct flame) or on a grill over the fire, and cook for 30 to 45 minutes, flipping once — check for doneness before serving. On a pellet grill or oven set to 425°F, bake the packets on a sheet pan for 20-25 minutes until everything is hot, bubbly, and deeply aromatic. The shrimp should be pink and curled, and the potatoes fork tender.

How to Serve Cajun Shrimp Boil in Foil

Garnishes

This Cajun Shrimp Boil in Foil absolutely shines when topped with a sprinkle of fresh parsley or a few lemon wedges. If you really want that Southern flair, a dusting of extra Cajun seasoning or a pat of melted butter right out of the oven makes every bite even more luscious.

Side Dishes

Keep things classic with some crusty French bread to soak up the flavorful juices, or serve alongside creamy coleslaw or a simple green salad. Cold drinks and cold beer complete the backyard-boil vibe — perfect for summer evenings or casual gatherings.

Creative Ways to Present

For a party, let everyone open their own foil packet at the table for that big, dramatic steam reveal! Or, empty the cooked contents onto a big platter lined with parchment for a vibrant, family-style spread. Either way, Cajun Shrimp Boil in Foil makes dinner feel like an experience worth savoring.

Make Ahead and Storage

Storing Leftovers

If you happen to have any of this Cajun Shrimp Boil in Foil left, simply transfer it to an airtight container and refrigerate. The flavors actually get even richer overnight and will keep for up to 2 days. Be sure to discard any leftover shells or tails for the best texture.

Freezing

While shrimp can sometimes go a bit rubbery after freezing, you can freeze the cooked mixture if needed. Cool everything completely, then seal in freezer-safe containers for up to one month. Thaw overnight in the fridge before reheating.

Reheating

To bring back that just-made magic, reheat leftovers in a covered skillet over medium-low heat, adding a splash of water or broth to help steam everything gently. Alternatively, wrap leftovers in foil and pop them in the oven at 350°F until heated through. Avoid microwaving if possible, as the shrimp can get tough.

FAQs

Can I use frozen shrimp for Cajun Shrimp Boil in Foil?

Yes! Just make sure to thaw the shrimp completely and pat dry before tossing them with the other ingredients. This helps prevent excess moisture and ensures everything cooks evenly.

What’s the best way to prepare potatoes and corn for this recipe?

For even cooking, cut potatoes into small, bite-sized pieces or parboil them for several minutes. Corn should be sliced into rounds. This way, they’ll finish at the same time as the shrimp and sausage in your foil packets.

Can I add other seafood or vegetables?

Absolutely! Add mussels, crab, or even chunks of fish for extra seafood goodness. Bell peppers or zucchini also work well if you want more veggie action in your Cajun Shrimp Boil in Foil.

Is this recipe spicy?

That’s entirely up to you. The cayenne pepper adds a classic Cajun heat, but you can tone it down or bump it up based on your taste preferences. The rest of the spices bring plenty of flavor without overwhelming heat.

Do I need to use heavy-duty foil?

Heavy-duty foil is highly recommended because it holds up better to the heat of the grill, oven, or campfire and helps prevent splitting or leaks. Double up regular foil if needed for extra strength.
