01 - Pat the cod fillets completely dry with paper towels, then season both sides generously with salt and pepper.
02 - Heat 2 tablespoons of butter in a large skillet over medium heat until melted and beginning to foam.
03 - Add the minced garlic to the hot butter and sauté for approximately 30 seconds until fragrant, taking care not to brown or burn it.
04 - Gently place the seasoned cod fillets in the skillet. Cook for 3–4 minutes on the first side until golden, then carefully flip using a thin spatula.
05 - Add the remaining butter, lemon juice, and lemon zest to the pan. As the butter melts, continuously baste the fish with the sauce for another 3–4 minutes until the cod is completely opaque and flakes easily with a fork.
06 - Sprinkle the chopped parsley over the fish and remove from heat immediately. Serve hot, spooning the remaining lemon garlic butter sauce over each fillet. Garnish with fresh lemon wedges if desired.
