# What You Need:

02 - 12 large shrimp, peeled and deveined, optional

→ Vegetables

03 - 2 ears corn, each cut into 4 pieces

→ Sausage

07 - 8 oz andouille or smoked sausage, sliced

→ Seasonings

08 - 2 tbsp Cajun seasoning blend
09 - 1 tsp garlic powder
10 - 1 tsp smoked paprika
11 - 1/2 tsp ground black pepper
12 - 1/2 tsp salt
13 - 1/4 tsp cayenne pepper, optional

→ Fats and Liquids

14 - 4 tbsp unsalted butter, melted
15 - 2 tbsp olive oil

→ Garnish

16 - 2 tbsp fresh parsley, chopped

# Steps:

01 - Preheat grill to medium-high heat, approximately 400°F.
02 - In a large bowl, combine crawfish tails, shrimp if using, corn, potatoes, onion, sausage, and lemon slices.
03 - Drizzle mixture with melted butter and olive oil. Sprinkle with Cajun seasoning, garlic powder, smoked paprika, black pepper, salt, and cayenne pepper. Toss thoroughly until all ingredients are evenly coated.
04 - Cut four sheets of heavy-duty aluminum foil, each approximately 16 inches. Divide seasoned mixture evenly among foil sheets, piling ingredients in the center of each.
05 - Fold up short sides first, then long sides, sealing each packet tightly to prevent liquid leakage.
06 - Place packets seam-side up on preheated grill. Cook for 20 to 25 minutes, turning once halfway through, until potatoes are fork-tender and seafood is heated through.
07 - Carefully open packets while watching for escaping steam. Garnish with fresh parsley and serve hot with additional lemon wedges if desired.

# Expert Suggestions:

01 -
  • Every packet is basically a complete meal that cooks hands-off while you chat with guests instead of fussing over a giant pot.
  • The foil keeps everything steaming in its own little buttery world, so flavors get concentrated and nothing dries out.
  • Cleanup is genuinely a breeze because there's no giant pot to scrub and your grill barely needs attention.
02 -
  • Heavy-duty foil is genuinely non-negotiable because regular foil will tear and you'll end up with butter all over your grill, a lesson I learned the expensive way.
  • Don't open the packets before checking that the potatoes are actually soft because undercooked potatoes will ruin the whole experience and there's no way to fix it once they're off the heat.
03 -
  • Write each person's name on their packet with a marker before grilling so you can easily keep track of who's got dairy-free or extra spice versions.
  • If your grill has hot and cool spots, rotate the packets from hot to cool halfway through so they cook evenly without any burnt edges.
