01 - Preheat the oven to 410°F. Line a baking tray with parchment paper and lightly coat with oil.
02 - Pat the fish fillets thoroughly 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 panko breadcrumbs, chopped dill, lemon zest, garlic powder, paprika, salt, and pepper in the third bowl.
04 - Dredge each fish fillet in the flour, shaking off excess. Dip into the beaten egg, allowing excess to drip off. Press firmly into the crumb mixture, ensuring even coating on all sides.
05 - Place the coated fillets on the prepared baking tray in a single layer. Drizzle or brush the tops with olive oil.
06 - Bake for 15 to 20 minutes, or until the fish flakes easily with a fork and the crumb coating is golden brown and crispy.
07 - While the fish bakes, combine Greek yoghurt, diced cucumber, chopped dill, lemon juice, lemon zest, minced garlic, salt, and pepper in a bowl. Mix thoroughly and refrigerate until ready to serve.
08 - Serve the baked fish immediately with a generous portion of cucumber yoghurt sauce and fresh lemon wedges on the side.
