01 - Pat salmon fillets dry using paper towels. Generously season both sides with salt and freshly ground black pepper.
02 - Warm olive oil in a large nonstick skillet over medium-high heat.
03 - Place the salmon fillets skin-side down if using skin-on. Cook for 4 to 5 minutes, allowing the skin to crisp and the meat to turn opaque through most of its thickness.
04 - Carefully flip the fillets and continue to cook for 2 to 3 minutes, until just cooked through. Transfer salmon to a plate and loosely cover with foil.
05 - Reduce skillet heat to medium. Add unsalted butter, allowing it to melt, then stir in minced garlic. Sauté for 30 seconds until aromatic.
06 - Incorporate fresh lemon juice and zest, then stir in chopped parsley.
07 - Return salmon fillets to the skillet. Spoon garlic butter sauce over the fish for 1 to 2 minutes to warm through and glaze.
08 - Serve immediately, garnished with additional parsley and lemon wedges if desired.
