01 - Preheat oven to 410°F. Line a baking sheet with parchment paper and lightly coat with oil.
02 - Pat fish fillets completely dry with 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, dill, lemon zest, garlic powder, paprika, salt, and pepper in the third.
04 - Dredge each fillet in flour, shaking off excess. Dip into beaten egg, then press firmly into crumb mixture to coat evenly on all sides.
05 - Place coated fillets on the prepared baking sheet. Drizzle or brush with olive oil to promote golden browning.
06 - Bake for 15 to 20 minutes until fish is opaque throughout and crumbs are deep golden and crisp.
07 - While fish bakes, combine Greek yoghurt, cucumber, dill, lemon juice, lemon zest, garlic, salt, and pepper in a bowl. Mix thoroughly and refrigerate until serving.
08 - Plate baked fish immediately with a generous dollop of cucumber yoghurt sauce and fresh lemon wedges on the side.
