Instructions

  1. Step 1: In a shallow dish, combine 1/4 cup fresh lemon juice, 3 tbsp olive oil, 3 minced garlic cloves, 1 tbsp dried oregano, 1 tsp salt, 1/2 tsp black pepper, and 1 tsp lemon zest. Whisk until combined.
  2. Step 2: Place 4 sea bass fillets (6 oz each) in the marinade, turning to coat all sides. Cover and refrigerate for 30 minutes to 1 hour.
  3. Step 3: Preheat grill to medium heat (350-375°F). Oil the grill grates to prevent sticking.
  4. Step 4: Remove the fillets from the marinade and grill for 4-5 minutes per side, until the fish is opaque and flakes easily with a fork.
  5. Step 5: Transfer to a serving plate and sprinkle with 2 tbsp chopped fresh parsley before serving immediately.
