Ingredients

Instructions

  1. Step 1: Pat dry 4 sea bass fillets and season both sides with 1 1/2 tsp salt and 1 tsp freshly ground black pepper.
  2. Step 2: Heat 3 tbsp olive oil in a large non-stick skillet over medium-high heat. Add the fillets skin side down and cook for 4-5 minutes without moving until the skin is crisp and golden brown.
  3. Step 3: Carefully flip the fillets and cook for another 3-4 minutes until the fish is opaque and flakes easily with a fork. Transfer the cooked fish to a warm plate.
  4. Step 4: Reduce heat to medium and add 4 tbsp unsalted butter to the skillet. When melted, add 2 tbsp drained capers, 3 tbsp fresh lemon juice, and 2 minced garlic cloves. Cook for 1-2 minutes, stirring, until the garlic is fragrant and the sauce slightly thickens.
  5. Step 5: Pour the lemon-caper butter sauce over the sea bass and garnish with 2 tbsp chopped fresh parsley before serving.
