01 - Preheat the oven to 410°F. Line a baking tray 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 - Set up three shallow bowls: place flour in the first bowl, beaten eggs in the second, and combine all crumb mixture ingredients (panko, dill, lemon zest, garlic powder, paprika, salt, pepper) in the third bowl.
04 - Dip each fish fillet first in flour, shaking off excess, then in beaten egg, allowing excess to drip off, then press firmly into crumb mixture to coat evenly on all sides.
05 - Place coated fillets on the prepared baking tray in a single layer. Drizzle or brush with olive oil.
06 - Bake for 15 to 20 minutes until fish is cooked through and crumbs are golden brown 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 - Serve baked fish immediately topped with a generous portion of cucumber yoghurt sauce and lemon wedges on the side.
