01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease a baking dish.
02 - Pat the cod fillets dry with paper towels. Arrange fillets on the prepared baking sheet. Drizzle with lemon juice and season evenly with salt and pepper.
03 - In a medium bowl, combine crushed buttery crackers, melted butter, chopped parsley, garlic powder, and lemon zest. Mix until the crumbs are evenly moistened.
04 - Spoon the crumb mixture evenly over the tops of the cod fillets, pressing gently so it adheres.
05 - Bake for 15–20 minutes, or until the fish flakes easily with a fork and the topping is golden brown.
06 - Serve immediately, garnished with lemon wedges and extra parsley if desired.
