01 - Preheat the oven to 410°F. Line a baking tray with parchment paper and lightly oil the surface.
02 - Pat fish fillets completely dry with paper towels. Season both sides generously with salt and freshly ground black pepper.
03 - Set up three shallow bowls: place flour in the first, beaten eggs in the second, and combine panko breadcrumbs, dill, lemon zest, garlic powder, paprika, salt, and pepper in the third bowl.
04 - Dip each seasoned fish fillet in flour, shaking off excess. Transfer to beaten eggs, allowing excess to drip off. Press firmly into crumb mixture, ensuring complete and even coating.
05 - Place coated fillets on the prepared baking tray in a single layer. Drizzle or brush olive oil evenly over the top of each fillet.
06 - Bake for 15-20 minutes until the fish is opaque throughout and the crumb coating is golden brown and crispy.
07 - While fish bakes, combine Greek yoghurt, diced cucumber, dill, lemon juice, lemon zest, minced garlic, salt, and pepper in a bowl. Mix thoroughly and refrigerate until serving.
08 - Serve hot baked fish fillets topped with chilled cucumber yoghurt sauce and accompanied by fresh lemon wedges.
