What is Blackened Shrimp?

Blackening, or “blackened”, is a cooking method associated with Cajun cuisine that is done by darkening a food with a spice mixture in a hot pan or cast-iron skillet. The specific spice blend used to blacken a food may vary from one recipe to the next, but it typically includes paprika, garlic powder, onion powder, dried oregano, cayenne pepper, and salt. Some blackened seasoning also includes brown sugar; however, this is optional.

Although commonly used on fish and poultry, like these blackened fish tacos and blackened salmon, any form of animal protein can be blackened with the spice mixture.Small white bowl with spices for blackening seasoning; smoked paprika, onion, garlic, oregano, cayenne pepper, and salt.

How to Make Blackening Seasoning

Once you’ve got the basics of the blackened seasoning down, you can easily mix and match the spice mixture to create the exact flavor combination that you enjoy. My version of blackened shrimp calls for paprika, garlic powder, onion powder, cayenne pepper, oregano, and salt, but a pinch of chili powder and brown sugar would mix in very nicely too.

Not only is blackened shrimp easy to make but it’s incredibly versatile. The cooked shrimp can be eaten on its own, with a dip, layered into tacos, wrapped in burritos, served in lettuce wraps, made into rice bowls, topped onto pasta, or topped onto your favorite salad for a quick, easy, and absolutely delicious meal.Bowl with rice, black beans, bell peppers, avocado and blackened shrimp with cilantro and lime wedges.

Storage + Reheating

To Refrigerate: Allow the blackened shrimp to cool completely and then store it in an airtight container in the fridge for 3 to 4 days.

To Freeze: Once cooled, place the cooked shrimp in an airtight container or freezer-safe bag and freeze for up to 3 months.


To Reheat: For the best results, once thawed, reheat the shrimp in a pan with a bit of oil on the stovetop on low-medium heat for 1-2 minutes or until warm. They can also be reheated in the microwave for 30 seconds to 1 minute.

Blackened Shrimp

Made with a Cajun-inspired spice mixture, this blackened shrimp recipe is packed full of flavor, while being quick and easy to make!


  • 1 pound deveined shrimp, raw, thawed if frozen
  • 3 teaspoons smoked paprika
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon cayenne pepper
  • 1/2 teaspoon salt
  • 1 tablespoon olive oil


  • In a small bowl, combine the spices; paprika, garlic, onion, oregano, cayenne pepper, and salt, and stir to combine.
  • Add raw shrimp to a medium bowl, cover with the spice mixture, and toss shrimp until well coated in the spices. If time permits, set aside 15 minutes to allow the shrimp to marinate, however, this is not necessary.
  • In a large cast-iron skillet or heavy bottom pan, warm olive oil. Add shrimp, arranging them in a single layer, and allow to cook 2-3 minutes per side until cooked through and lightly blackened on both sides.
  • Serve the cooked shrimp immediately on its own or with lime wedges and fresh cilantro or store in an airtight container in the fridge for up to 3 days.


If using frozen shrimp, ensure that they are completely thawed before cooking. If time permits, place them in an airtight container and allow them to thaw in the fridge overnight. If you are pressed for time, you can thaw frozen shrimp by placing them in a bowl with cold water for about 20 minutes.
