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 ensure even coating. 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 baking: arrange the marinated fillets on a parchment-lined baking tray and bake for 12–15 minutes until the fish is opaque and flakes easily with a fork. For pan-searing: place the fillets in the hot skillet and cook for 3–4 minutes per side until golden and cooked through.
05 - Transfer the cooked fillets to serving plates, sprinkle with finely chopped fresh parsley, and serve immediately with lemon wedges on the side.
