01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease a suitable baking dish.
02 - Gently pat the haddock fillets dry with paper towels to remove excess moisture, then arrange them in a single layer on the prepared baking sheet.
03 - In a medium mixing bowl, thoroughly combine the fresh breadcrumbs, grated Parmesan cheese, finely chopped fresh parsley, lemon zest, dried thyme, paprika, salt, and black pepper.
04 - Evenly drizzle the haddock fillets with the melted unsalted butter, olive oil, and fresh lemon juice.
05 - Press the prepared breadcrumb mixture evenly over the top surface of each fillet, ensuring a gentle but firm adhesion.
06 - Bake for 15 to 20 minutes, or until the fish is opaque throughout, flakes easily with a fork, and the topping is golden brown.
07 - Serve the baked haddock immediately, garnished with fresh lemon wedges and additional chopped parsley if desired.
