01 - Pat the cod fillets dry with paper towels and season both sides with salt and pepper.
02 - Heat 2 tablespoons of butter in a large skillet over medium heat until melted and foaming.
03 - Add the minced garlic and sauté for 30 seconds until fragrant, being careful not to burn it.
04 - Gently place the cod fillets in the skillet. Cook for 3–4 minutes on the first side, then carefully flip using a thin spatula.
05 - Add the remaining butter, lemon juice, and zest to the pan. Baste the fish with the melting butter sauce as it cooks for another 3–4 minutes, or until the cod is opaque and flakes easily with a fork.
06 - Sprinkle with chopped parsley and remove from the heat.
07 - Serve immediately, spooning extra lemon garlic butter sauce over each fillet. Garnish with lemon wedges if desired.
