01 - Pat salmon fillets dry with paper towels to ensure proper searing.
02 - In a small bowl, whisk together olive oil, lemon juice, lemon zest, cinnamon, smoked paprika, garlic powder, black pepper, and salt until fully incorporated.
03 - Brush the marinade generously over both sides of each salmon fillet, ensuring even coverage.
04 - Place a large non-stick or cast-iron skillet over medium-high heat and allow it to get thoroughly hot.
05 - Arrange salmon fillets in the hot skillet, skin-side down if using skin, and cook without moving for 4–5 minutes until a golden crust forms.
06 - Carefully flip each fillet and cook for an additional 3–4 minutes, or until the salmon is just cooked through and flakes easily when tested with a fork.
07 - Remove skillet from heat and let the salmon rest for 2 minutes to allow juices to redistribute.
08 - Transfer salmon to plates and serve warm, garnished with fresh lemon wedges and chopped parsley if desired.
