Instructions

  1. Step 1: Preheat grill to medium-high heat (about 400°F). Brush 4 sea bass fillets with 2 tbsp olive oil and season with 1 tsp salt and 1/2 tsp black pepper. Set aside.
  2. Step 2: In a small bowl, combine 1 tbsp chopped rosemary, 1 tbsp chopped thyme, 3 minced garlic cloves, 2 tbsp lemon juice, 1 tbsp chopped capers, 1/4 cup chopped flat-leaf parsley, and remaining 1 tbsp olive oil. Stir well to create the herb sauce.
  3. Step 3: Place the sea bass fillets skin-side down on the grill. Cook for 4-5 minutes until the skin is crisp and golden, then carefully flip and grill an additional 3-4 minutes until the fish is opaque and flakes easily with a fork.
  4. Step 4: Transfer the grilled sea bass to plates and spoon the Istrian herb sauce generously over each fillet while still hot. Serve immediately.
