Ingredients
  

Salmon
  • 4 (6 oz / 170 g each) skin-on salmon filets
  • 3 tbsp melted butter or avocado oil
Cajun Spice Crust
  • 2 tsp smoked paprika
  • 2 tsp ground cumin
  • 2 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp dried oregano
  • 1/2 tsp chili powder
  • 1/2 tsp cayenne pepper
  • 1 tsp salt
  • 1/2 tsp black pepper
Garnish and Finish
  • Juice of 1/2 lemon
  • 1 tbsp fresh parsley, chopped

Method
 

Preparation
  1. Mix smoked paprika, ground cumin, garlic powder, onion powder, dried oregano, chili powder, cayenne pepper, salt, and black pepper together in a small bowl.
  2. Dry the salmon filets thoroughly with paper towels.
  3. Coat both sides of the salmon filets with melted butter or avocado oil.
  4. Apply the spice mixture evenly over both sides of the salmon filets, pressing it gently into the surface.
Cooking
  1. Warm a cast-iron skillet over high heat until it begins to lightly smoke.
  2. Place the salmon in the hot skillet with the skin side facing down and cook undisturbed for 4 to 5 minutes.
  3. Turn the salmon carefully and continue cooking for another 3 to 4 minutes, until the crust has darkened and the fish flakes easily.
  4. Take the salmon off the heat, add lemon juice, and finish with chopped parsley.
  5. Serve the salmon when it reaches 145°F / 63°C internally for safe consumption.

Notes

For a milder spice level, use less cayenne pepper.
