In a small bowl, combine the grated Parmesan cheese, panko breadcrumbs, melted butter, minced garlic, chopped parsley, lemon juice, and dried oregano. Mix until all ingredients are well incorporated and the mixture has a slightly moist but crumbly texture.

Pat the flounder fillets dry with paper towels. This helps the topping stick better and ensures crispy results. Season both sides lightly with salt and pepper.

Arrange the seasoned flounder fillets on the prepared baking sheet, spacing them evenly. Generously spoon the Parmesan-garlic mixture over each fillet, pressing down gently to create an even layer that adheres to the fish.

Place the baking sheet in the preheated oven and bake for 12-15 minutes, or until the fish flakes easily with a fork and the topping turns golden brown and crispy.

Remove from the oven and let rest for a minute. Carefully transfer the fillets to serving plates, garnish with lemon wedges, and serve immediately while hot and crispy.
