01 - Pat the salmon fillets dry with paper towels. Season both sides generously with salt and freshly ground black pepper.
02 - Heat 2 tablespoons of butter in a large nonstick skillet over medium-high heat until melted and foamy.
03 - Place the salmon fillets in the skillet, skin-side down if using skin-on. Cook for 4–5 minutes until the bottom is golden and the salmon is mostly opaque.
04 - Flip the fillets and add the remaining 2 tablespoons of butter, minced garlic, and lemon zest to the pan. Cook for 2–3 more minutes, basting the salmon occasionally 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.
