01 - Preheat the oven to 410°F. Line a baking sheet with parchment paper and lightly coat with oil.
02 - Pat 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, 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 flour, shaking off excess. Dip into beaten egg, then press firmly into crumb mixture, ensuring even coating 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 flakes easily with a fork and the crumb coating is golden brown and crispy.
07 - While fish bakes, combine Greek yogurt, diced cucumber, chopped dill, lemon juice, lemon zest, minced garlic, salt, and pepper in a bowl. Mix thoroughly and refrigerate until serving.
08 - Serve hot baked fish immediately with chilled cucumber yogurt sauce and fresh lemon wedges on the side.
