01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease a baking dish.
02 - Pat the fish fillets dry with paper towels and arrange in a single layer on the prepared baking sheet.
03 - In a small bowl, whisk together olive oil, lemon juice, lemon zest, minced garlic, oregano, salt, and pepper until well combined.
04 - Drizzle the marinade evenly over the fish fillets, ensuring complete coverage on all surfaces.
05 - Bake for 15 to 20 minutes, or until the fish is opaque and flakes easily with a fork, depending on fillet thickness.
06 - Remove from oven, sprinkle with chopped parsley, and serve immediately with lemon wedges.
