Instructions

  1. Step 1: Pat dry 4 Chilean sea bass fillets (6 oz each) and season both sides with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat until shimmering. Add the fillets skin-side down and cook for 5-6 minutes until the skin is crisp and edges turn opaque.
  3. Step 3: Carefully flip the fillets and cook for an additional 3-4 minutes until fish is opaque and flakes easily.
  4. Step 4: Remove the fillets from the skillet and set aside on a warm plate.
  5. Step 5: Reduce heat to medium and add 3 tbsp unsalted butter to the same skillet. Once melted, stir in 2 minced garlic cloves and sauté for 30 seconds until fragrant.
  6. Step 6: Add 3 tbsp fresh lemon juice and 2 tbsp drained capers to the skillet. Cook for 1 minute until the sauce slightly thickens.
  7. Step 7: Remove from heat and stir in 2 tbsp chopped fresh parsley, then spoon the sauce evenly over the sea bass fillets before serving.
