Ingredients
  

  • Salmon: 4 fillets (about 6 ounces each), skin-on preferred
  • Butter: 2 tablespoons, melted (or use oil for dairy-free)
  • Olive oil or avocado oil: 1–2 tablespoons for the pan
  • Lemon: 1, cut into wedges
  • Fresh herbs (optional): Parsley or cilantro for garnish
  • Cajun seasoning blend:
  • 2 teaspoons smoked paprika (or sweet paprika if you prefer)
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1/2–1 teaspoon cayenne pepper (adjust to taste)
  • 1/2 teaspoon brown sugar (optional, helps balance heat and aids browning)

Method
 

  1. Pat the salmon dry. Use paper towels to remove surface moisture. Dry fish browns better and sticks less.
  2. Mix the Cajun blend. In a small bowl, combine paprika, garlic powder, onion powder, thyme, oregano, salt, black pepper, cayenne, and brown sugar if using.
  3. Brush with melted butter. Coat the flesh side of the salmon lightly. This helps the spices cling and creates a better crust.
  4. Season generously. Sprinkle the Cajun mix over the salmon, pressing it in so it forms a uniform layer. Keep the skin side unseasoned.
  5. Preheat the pan. Heat a large cast-iron or heavy skillet over medium-high until hot. Add oil and let it shimmer.
  6. Sear flesh side down. Place salmon in the skillet, seasoned side down. Cook without moving for 2–3 minutes, until a dark crust forms.
  7. Flip and finish. Carefully flip and cook skin side down for another 3–5 minutes, depending on thickness. You’re aiming for medium doneness and a flaky center.
  8. Add a quick baste (optional). Spoon a little melted butter over the tops in the last minute for extra richness.
  9. Rest and serve. Transfer to plates, squeeze with lemon, and garnish with herbs. Serve immediately.
