01 - Pat the cod fillets completely dry using paper towels, then season both sides generously with salt and pepper. This ensures proper browning and flavor penetration.
02 - Place 2 tablespoons of butter in a large skillet over medium heat. Allow the butter to melt completely and begin foaming, indicating the pan is properly heated for cooking.
03 - Add the minced garlic to the melted butter. Sauté for approximately 30 seconds until fragrant, stirring constantly to prevent browning or burning.
04 - Gently place the seasoned cod fillets into the skillet. Cook for 3 to 4 minutes on the first side until a golden crust forms, then carefully flip each fillet using a thin, flexible spatula.
05 - Add the remaining butter, lemon juice, and lemon zest to the pan. As the butter melts, spoon the sauce continuously over the fish. Cook for another 3 to 4 minutes until the cod is opaque throughout and flakes easily when tested with a fork.
06 - Sprinkle the finely chopped fresh parsley evenly over the cod fillets. Remove the skillet from heat immediately to preserve the fresh herb flavor and prevent overcooking.
07 - Transfer each cod fillet to serving plates. Spoon the remaining lemon garlic butter sauce generously over the top. Garnish with fresh lemon wedges if desired and serve immediately while hot.
