01 - Preheat oven to 410°F. Line a baking tray with parchment paper and lightly coat with oil.
02 - Pat fish fillets completely dry using paper towels. Season both sides generously with salt and pepper.
03 - Arrange three shallow bowls: place flour in the first, beaten eggs in the second, and combine panko breadcrumbs, chopped dill, lemon zest, garlic powder, paprika, salt, and pepper in the third.
04 - Dredge each fish fillet in flour, shaking off excess. Dip into beaten eggs, allowing excess to drip off. Press firmly into crumb mixture, ensuring complete and even coating on all sides.
05 - Place coated fillets on prepared baking tray. Drizzle or brush olive oil evenly over the top of each fillet.
06 - Bake for 15 to 20 minutes until fish is cooked through and crumbs are deep golden brown and crisp.
07 - Combine Greek yoghurt, diced cucumber, chopped dill, lemon juice, lemon zest, minced garlic, salt, and pepper in a bowl. Mix thoroughly until well blended. Refrigerate until ready to serve.
08 - Plate hot baked fish with a generous portion of cucumber yoghurt sauce. Accompany with lemon wedges for squeezing over the fish.
