Ingredients You’ll Need

For the Cajun Shrimp

• 2 tablespoons Cajun seasoning – Adds bold smoky spice and authentic Southern flavor.
• 1 tablespoon olive oil – Helps the seasoning adhere while promoting beautiful grill marks.

For the Sandwiches

• 4 hoagie rolls or baguettes – Soft inside with a lightly crisp exterior after toasting.
• Shredded lettuce – Adds cool, refreshing crunch.
• Sliced tomatoes – Bring juicy freshness and color.
• Pickles – Add tangy contrast to the smoky shrimp.
• Mayonnaise – Provides creamy richness.
• Hot sauce (optional) – For an extra burst of heat.

Optional Garnishes

• Sliced avocado
• Green onions
• Fresh parsley
• Lemon wedges
• Remoulade sauce

Step-by-Step Instructions

Step 1: Preheat the Grill

Preheat your grill to medium-high heat.

Lightly oil the grill grates to prevent the shrimp from sticking.

Step 2: Season the Shrimp

In a large bowl, combine:

• Peeled and deveined shrimp
• Cajun seasoning
• Olive oil

Toss until every shrimp is evenly coated with the seasoning mixture.

Step 3: Thread the Shrimp

Thread the seasoned shrimp onto skewers.

If using wooden skewers, soak them in water for at least 30 minutes beforehand to prevent burning.

Step 4: Grill the Shrimp

Place the shrimp skewers on the hot grill.

Cook for 2–3 minutes per side, turning once, until:

• The shrimp are pink and opaque.
• Light grill marks appear.
• They curl into a loose “C” shape.

Avoid overcooking, as shrimp can become tough very quickly.

Step 5: Toast the Rolls

Place the hoagie rolls cut-side down on the grill.

Toast for about 1 minute, or until lightly golden and crisp.

Remove from the grill.

Step 6: Assemble the Sandwiches

Spread a generous layer of mayonnaise inside each toasted roll.

Layer with:

• Shredded lettuce
• Sliced tomatoes
• Grilled Cajun shrimp
• Pickles

Drizzle with hot sauce if you enjoy extra heat.

Step 7: Serve

Serve immediately while the shrimp are warm and juicy.

Pair with your favorite sides and enjoy.

Recipe Notes & Tips

• Don’t Overcook the Shrimp – Remove them from the grill as soon as they turn opaque.
• Use Large Shrimp – They stay juicier and are easier to grill.
• Toast the Bread – Lightly toasted rolls help prevent sogginess.
• Adjust the Spice – Add more Cajun seasoning or hot sauce for extra heat.
• Fresh Lemon Brightens the Flavor – A squeeze of lemon before serving enhances the seafood beautifully.
• Try Homemade Remoulade – Swap mayonnaise for remoulade sauce for an authentic Louisiana twist.

Storage & Serving Tips

• Reheat Gently – Warm the shrimp briefly in a skillet over medium heat or in the microwave for a short time.
• Assemble Fresh – Build the sandwiches just before serving for the best flavor and texture.

Creative Variations to Try

• Blackened Shrimp Po’ Boy – Cook the shrimp in a cast-iron skillet instead of grilling for a classic blackened crust.

• Surf and Turf Po’ Boy – Add sliced grilled Andouille sausage for an even heartier Cajun sandwich.

Troubleshooting Common Issues

• Shrimp Turn Rubbery – They were overcooked; grill only until pink and opaque.
• Bread Becomes Soggy – Toast the rolls and pat the tomatoes dry before assembling.
• Seasoning Doesn’t Stick – Toss the shrimp thoroughly with olive oil before adding the Cajun seasoning.
• Shrimp Stick to the Grill – Clean and oil the grates before grilling, and avoid moving the shrimp too soon.
