01 - Pat the salmon fillets dry with paper towels and season both sides generously with salt and freshly ground black pepper.
02 - Melt 2 tablespoons of unsalted butter in a large nonstick skillet over medium-high heat until foamy.
03 - Place the salmon fillets in the skillet skin-side down. Cook for 4 to 5 minutes until the bottom turns golden and the flesh becomes mostly opaque.
04 - Flip the fillets and add the remaining 2 tablespoons of butter, minced garlic, and lemon zest to the pan. Cook for 2 to 3 minutes, basting the salmon continuously with the melted garlic butter.
05 - Squeeze fresh lemon juice over the fillets and sprinkle with chopped parsley. Remove from heat when the salmon flakes easily with a fork.
06 - Serve immediately, garnished with lemon wedges and extra parsley if desired.
