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 coat evenly. Let rest for at least 10 minutes, or up to 30 minutes for deeper flavor.
03 - Preheat the oven to 400°F if baking, or set a large non-stick skillet over medium heat if pan-searing.
04 - For baking: place the marinated fillets on a parchment-lined baking tray and bake for 12 to 15 minutes until the fish is opaque and flakes easily with a fork. For pan-searing: lay the fillets in the hot pan and cook 3 to 4 minutes per side until golden and cooked through.
05 - Transfer the cooked fillets to serving plates, sprinkle with chopped parsley, and accompany each portion with a lemon wedge.
