Blackening is a classic Cajun cooking technique that adds complex flavor and dark color to fish, as well as shellfish and chicken. This traditional seasoning recipe includes paprika, herbs, and cayenne pepper, as well as white and black pepper, garlic powder, and salt. The seasoning is rubbed on fish fillets which are then placed in an extremely hot cast iron skillet, creating a blackened, crusty coating with a little bit of spice.

Blackened Cajun fish goes well with a variety of side dishes, such as coleslaw, dirty rice, fresh corn fritters, cheese grits, and sweet potato fries. Serve with plenty of lemons for squeezing.

  • 1 tablespoon dried oregano

  • 1 tablespoon cayenne pepper

  • To use the seasoning mix, simply apply a generous amount of rub onto the flesh of the fish. Cook the fish in a hot skillet, flipping once, until the flesh is opaque.
  • This seasoning rub works on a wide variety of fish. Although catfish is the most popular, many types of fish can be blackened, including trout, red snapper, cod, tilapia, and even salmon. Thicker, sturdier fish can be grilled while more delicate varieties should be pan-fried.
  • The mixture can be made into a marinade as well. Add 1/4 cup oil and either 1/3 cup vinegar (white or cider) or citrus juices (orange, lemon, or lime) to a bowl and whisk together with seasoning rub. Marinate fish and shellfish for 20 to 30 minutes max; chicken can sit in the marinade for much longer, up to 12 hours. Pan-fry or grill until done.
