Ingredients

Scale
  • 4 (6 ounce) salmon fillets, skin on or off
  • 2 tablespoons olive oil or butter, melted
  • 1 tablespoon smoked paprika
  • 1 tablespoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried oregano
  • 1 teaspoon dried thyme
  • 1 teaspoon cayenne pepper (adjust for spice level)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon dried basil
  • 1/4 teaspoon ground cumin
  • 1/4 cup unsalted butter, for searing

Instructions

  1. Prepare the spice blend: In a small bowl, mix together the smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, salt, black pepper, basil, and cumin. This is your best blackened seasoning blend.
  2. Pat the salmon fillets completely dry using paper towels. This step helps create a crispy skin and a better crust.
  3. Brush the tops and sides of each salmon fillet lightly with the melted olive oil or butter.
  4. Generously coat the oiled salmon fillets on all sides with the prepared Cajun spice rub, pressing gently so the seasoning adheres well.
  5. Heat a large, heavy-bottomed skillet (cast iron works best for that perfect sear) over medium-high heat. Add the 1/4 cup of unsalted butter to the skillet. Let the butter melt and foam, heating until it just begins to smoke slightly.
  6. Carefully place the seasoned salmon fillets into the hot skillet, seasoned-side down. Do not overcrowd the pan; cook in batches if necessary.
  7. Sear the salmon for 3 to 4 minutes without moving it to develop the dark, charred crust.
  8. Gently flip the fillets. Reduce the heat slightly to medium and cook for another 3 to 5 minutes, depending on the thickness of your fish, until the salmon is cooked through and flakes easily with a fork. The internal temperature should reach 145 degrees Fahrenheit.
  9. Remove the blackened salmon from the pan immediately and serve hot. This quick salmon dinner pairs well with rice or a fresh salad.

Notes

  • For extra crispy skin blackened salmon, ensure the skin side is down for the first sear, and keep the heat high enough to render the fat.
  • If you prefer a milder flavor, reduce the cayenne pepper in the rub or skip it entirely.
  • If you want a restaurant style salmon finish, serve with a simple lemon-dill yogurt sauce drizzled over the top.
