01 - Preheat oven to 400°F and lightly grease a baking dish large enough to hold all fillets in a single layer.
02 - Pat cod fillets dry, season both sides with salt and black pepper, then arrange in the baking dish. Drizzle evenly with lemon juice.
03 - In a medium bowl, mix crushed crackers, melted butter, parsley, garlic powder, paprika, and lemon zest until fully incorporated.
04 - Evenly spoon the cracker crumb mixture over cod fillets, gently pressing to adhere.
05 - Bake for 15 to 20 minutes until fish is opaque, flakes easily, and topping is golden brown.
06 - Let rest for 2 minutes after baking. Garnish with lemon wedges and extra parsley as desired. Serve promptly.
