Make the Blackening Seasoning: In a small bowl, whisk together the smoked paprika, garlic powder, onion powder, kosher salt, black pepper, oregano, thyme, and cayenne pepper until combined.

Prepare the Salmon: Pat the salmon fillets very dry with paper towels. This is important for creating a dark crust. Drizzle the salmon with olive oil, then generously coat all sides with the blackening seasoning.

Heat the Skillet: Heat a large cast iron skillet or heavy-bottomed pan over medium-high heat. Once hot, add a little olive oil.

Cook the Salmon: Place the salmon fillets in the skillet presentation-side down first. Cook undisturbed for about 4-5 minutes, depending on thickness, until a dark crust forms. Carefully flip and cook another 3-5 minutes until the salmon flakes easily with a fork and reaches your desired doneness.

Add Garlic Butter: Lower the heat slightly. Add the butter and chopped garlic to the skillet. Spoon the melted garlic butter over the salmon for about 30 seconds until fragrant.

Finish and Serve: Remove from heat and squeeze fresh lemon juice over the top and optional drizzle of honey. Garnish with parsley and serve immediately.
