01 - Preheat the oven to 400°F. Lightly grease a baking dish large enough to hold the cod fillets in a single layer.
02 - Pat cod fillets dry with paper towels and place them evenly in the prepared baking dish.
03 - Combine melted butter, minced garlic, lemon juice, sea salt, and freshly ground black pepper in a small bowl; whisk until blended.
04 - Pour the garlic butter mixture evenly over the cod fillets, ensuring full coverage.
05 - Bake in the preheated oven for 15 to 18 minutes, or until the fish flakes easily with a fork and appears opaque throughout.
06 - Remove from oven, sprinkle generously with chopped fresh parsley, and serve immediately with lemon wedges on the side.
