Blackened Cajun Shrimp: Bold and Spicy

Blackened shrimp is proof that big flavor doesn’t require big effort. A bold, smoky Cajun spice blend. A screaming-hot skillet. Two minutes per side. That’s it. The spice creates a dark, flavorful crust that’s not burnt—it’s blackened. There’s a difference, and it’s delicious.

These shrimp are the ultimate weeknight hero. Serve them over rice, tucked into tacos, piled on a salad, or just eaten straight from the pan with your fingers (no judgment). From start to finish, you’re looking at 10 minutes. Cajun dinner? Done.

Ingredients

Serves 4.

For the Blackened Shrimp:

• 1½ lbs large shrimp, peeled and deveined (tails on or off)
• 2 tbsp olive oil or avocado oil (high smoke point)
• 2 tbsp unsalted butter (optional, for extra richness)
• Lemon wedges, for serving
• Fresh parsley, for garnish

For the Cajun Spice Blend:

• 1 tbsp smoked paprika
• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tsp dried oregano
• 1 tsp dried thyme
• ½ tsp cayenne pepper (adjust to your heat preference)
• ½ tsp black pepper
• ½ tsp salt
• ¼ tsp white pepper (optional, adds depth)

Step-by-Step Instructions

Step 1: Make the Cajun Spice Blend

1. In a small bowl, combine smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne, black pepper, salt, and white pepper (if using).
2. Mix well. Store any extra in an airtight jar—it’s great on chicken, fish, and vegetables too.

Step 2: Prep the Shrimp

1. Pat shrimp completely dry with paper towels. This is crucial for getting a good sear.
2. Place shrimp in a bowl and drizzle with 1 tbsp oil. Toss to coat.
3. Sprinkle the Cajun spice blend generously over the shrimp. Toss until every shrimp is well coated. You want a thick layer of spice—that’s what creates the blackened crust.

Step 3: Heat the Skillet

1. Heat a large cast-iron skillet or heavy-bottomed pan over medium-high heat until it’s ripping hot. It should be almost smoking.
2. Add the remaining 1 tbsp oil (and butter if using) to the pan.

Step 4: Sear the Shrimp

1. Add shrimp to the skillet in a single layer. Don’t crowd the pan—work in batches if needed.
2. Cook undisturbed for 1½-2 minutes until the underside is deeply darkened and crispy. The spice should look blackened, not burnt.
3. Flip and cook another 1-2 minutes until shrimp are opaque, curled, and cooked through.
4. Remove immediately to a plate—they continue cooking off the heat.

Step 5: Serve and Devour

1. Squeeze fresh lemon juice over the hot shrimp. Garnish with parsley.
2. Serve over rice, in tacos, on a salad, or straight from the plate.
3. Take a bite. Feel the heat. Smile. You just made Louisiana in your kitchen.

Storage Notes

Leftovers:

Store in an airtight container in the fridge for up to 2 days. Shrimp are best fresh but make excellent leftovers for salads or tacos.

Reheating:

Skillet (best): Reheat over medium heat for 1 minute per side. Air fryer: 350°F for 2-3 minutes. Microwave: 20-30 seconds at reduced power—watch carefully to avoid rubbery shrimp.

Make Ahead:

Mix the Cajun spice blend up to 3 months in advance. Prep shrimp up to 24 hours ahead and keep refrigerated. Season and cook just before serving.
