Ingredients

- 2 tablespoons olive oil: for a healthy base that helps the spices stick and caramelize
- 1 tablespoon Cajun seasoning: delivers the smoky spicy flavor profile essential to this dish
- 1 teaspoon smoked paprika: adds a deep smoky depth opt for Spanish smoked paprika if you can find it
- Half teaspoon garlic powder: adds rich pungency
- Half teaspoon onion powder: boosts savory complexity
- Half teaspoon black pepper: for gentle heat
- Half teaspoon salt: to enhance all flavors
- 1 tablespoon fresh lemon juice: brightens and balances the spices perfect just before grilling
Instructions
- Prepare the Shrimp:
- Ensure the peeled and deveined shrimp with tails on are thoroughly patted dry to help them absorb the marinade better and achieve a delightful char.
- Marinate Shrimp:
- In a mixing bowl gently toss shrimp with olive oil Cajun seasoning smoked paprika garlic powder onion powder black pepper salt and lemon juice. Let it marinate at room temperature for about 15 to 20 minutes to allow flavors to penetrate.
- Preheat the Grill:
- Set a gas or charcoal grill to mediumhigh heat. Clean and oil the grates to ensure the shrimp does not stick.
- Grill Shrimp:
- Thread shrimp onto skewers or use a grilling basket and cook for 2 to 3 minutes per side. Grill until shrimp turns opaque and shows vibrant grill marks careful not to overcook as shrimp become tough quickly.

- Plate the shrimp as soon as they are removed from the grill garnish with fresh lemon wedges or chopped parsley and serve promptly to savor their tender juiciness.

My favorite ingredient here is smoked paprika which I learned really elevates the smoky flavor more than regular paprika. I remember a family cookout where this spice became the star everyone kept commenting on how perfect the smokiness was without overpowering the shrimp.
Storage Tips
Keep leftover grilled shrimp in an airtight container in the fridge for up to two days. Reheat gently in a skillet or microwave for best texture. Avoid overcooking when reheating.
Ingredient Substitutions
Swap shrimp for scallops for a richer texture that still soaks up the Cajun spices well. Use Creole seasoning to soften the heat and add herbal notes if you prefer a milder spice. For a culinary twist try alligator meat as a unique protein that holds the seasoning nicely.
Serving Suggestions
Serve grilled Cajun shrimp alongside grilled corn salsa or creamy grits for texture contrast. Pair with chilled white wine or zesty cocktails to bring out the spice notes.

These grilled Cajun shrimp are quick to make and deliver big flavor for any gathering. Serve with lemon wedges and enjoy.
