Create a flavorful, spicy, and savory crust on your salmon using this simple, homemade blackened seasoning blend. This rub is perfect for achieving that authentic Cajun-style char in your cast iron skillet.

Ingredients

Scale
  • 3 tablespoons smoked paprika
  • 2 tablespoons onion powder
  • 2 tablespoons garlic powder
  • 1 tablespoon dried oregano
  • 1 tablespoon dried thyme
  • 1 tablespoon cayenne pepper (adjust for heat preference)
  • 1 tablespoon salt
  • 1 teaspoon black pepper
  • 1 teaspoon ground cumin

Instructions

  1. Combine all the seasoning ingredients in a small bowl.
  2. Whisk the spices together thoroughly until the mixture is uniform. This ensures even flavor distribution.
  3. Store the homemade blackened seasoning mix in an airtight container in a cool, dark place for best flavor.
  4. To use, pat your salmon fillets dry with paper towels.
  5. Lightly brush the salmon fillets with melted butter or oil.
  6. Generously coat all sides of the salmon with the blackened spice blend, pressing gently so the rub adheres well. Use about 1 tablespoon of seasoning per 6-ounce fillet.
  7. Heat a cast iron skillet over medium-high heat until very hot. Add 1 tablespoon of high smoke point oil, like canola or grapeseed oil.
  8. Carefully place the seasoned salmon in the hot skillet. Cook for 3 to 4 minutes per side, depending on thickness, until a dark crust forms and the fish is cooked through. Do not move the fish until it is time to flip.

Notes

  • For best results, use a cast iron skillet to maintain the high heat needed for proper blackening.
  • If you do not have cayenne pepper, you can substitute with an extra teaspoon of paprika and a dash of chili powder for less intense heat.
  • This seasoning mix is also excellent on chicken breasts or pork chops.
  • This is a non-perishable salmon spice blend that keeps well for several months.
