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. Season both sides with salt and black pepper. Arrange fillets in the prepared baking dish and drizzle lemon juice evenly over them.
03 - Combine crushed crackers, melted butter, parsley, garlic powder, paprika, and lemon zest in a medium bowl. Mix until crumbs are uniformly coated.
04 - Spoon cracker crumb mixture evenly over the tops of the cod fillets, gently pressing to adhere.
05 - Bake for 15 to 20 minutes, until cod is opaque and flakes easily with a fork and the topping is golden brown.
06 - Remove from oven and let rest for 2 minutes. Garnish with lemon wedges and additional parsley if desired. Serve immediately.
