01 - Pat the cod fillets completely dry with paper towels. Generously season both sides with salt and pepper, ensuring even coverage.
02 - Place 2 tablespoons of butter in a large skillet over medium heat. Allow the butter to melt completely and begin foaming before proceeding.
03 - Add the minced garlic to the melted butter. Sauté for approximately 30 seconds until fragrant, stirring constantly to prevent burning.
04 - Gently place the seasoned cod fillets in the skillet, leaving space between each piece. Cook for 3-4 minutes on the first side until a golden crust forms.
05 - Carefully flip each fillet using a thin spatula. Add the remaining butter, lemon juice, and lemon zest to the pan. Spoon the melting butter sauce over the fish repeatedly as it cooks for another 3-4 minutes.
06 - The fish is done when it becomes completely opaque and flakes easily with a fork. Sprinkle with chopped parsley and remove from heat immediately.
07 - Transfer fillets to serving plates. Spoon the remaining lemon garlic butter sauce generously over each piece. Accompany with lemon wedges if desired.
