Instructions

  1. Step 1: Pat dry 4 sea bass fillets and season both sides with 1 1/2 tsp kosher salt and 1 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat. Add the fillets skin-side down and cook for 4-5 minutes until the skin is crisp and golden brown.

  5. Step 5: Pour in 1/2 cup dry white wine and 3 tbsp fresh lemon juice, simmering for 3-4 minutes until reduced by half.
  6. Step 6: Remove skillet from heat and whisk in 6 tbsp cold unsalted butter cubes one at a time until the sauce is smooth and emulsified.
  7. Step 7: Stir in 2 tbsp drained capers and 1 tbsp chopped fresh parsley, then spoon sauce over the sea bass fillets before serving.
