01 - In a small bowl, whisk together the fresh lemon juice, extra-virgin 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 coat evenly. Allow to marinate for at least 10 minutes, or up to 30 minutes for deeper flavor.
03 - Preheat the oven to 400°F if baking, or heat a large non-stick skillet over medium heat if pan-searing.
04 - For oven baking: Arrange the marinated fillets on a parchment-lined baking tray and bake for 12 to 15 minutes, until the flesh is opaque and flakes easily with a fork. For pan-searing: place fillets in the hot pan and cook for 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.
