01 - In a small bowl, whisk together the lemon juice, olive oil, minced garlic, sea salt, black pepper, and dried oregano or thyme until well combined.
02 - Arrange the fish fillets in a shallow dish and pour the marinade over them, turning each fillet to ensure even coating. Let marinate for at least 10 minutes or up to 30 minutes for deeper flavor.
03 - Preheat the oven to 400°F and line a baking tray with parchment paper, or alternatively heat a large non-stick skillet over medium heat on the stovetop.
04 - For oven baking, arrange the marinated fillets on the prepared tray and bake for 12 to 15 minutes until the fish turns opaque and flakes easily with a fork. For pan-searing, place fillets in the hot skillet and cook 3 to 4 minutes per side until golden brown and cooked through.
05 - Transfer the cooked fillets to serving plates, sprinkle generously with chopped fresh parsley, and accompany each portion with a lemon wedge.
