Ingredients
- 4 pieces, 6 oz each sea bass fillets
- 1 tsp salt
- 1/2 tsp black pepper
- 2 tbsp olive oil
- 6 tbsp, divided unsalted butter
- 2, finely minced shallots
- 1/2 cup dry white wine
- 3 tbsp fresh lemon juice
- 1, halved whole lemon
- 2 tbsp heavy cream
- 1 tbsp, chopped fresh parsley
Instructions
- Step 1: Preheat a skillet over medium-high heat and add 1 tbsp olive oil. Season 4 sea bass fillets evenly with 1 tsp salt and 1/2 tsp black pepper on both sides. Place fillets skin-side down in the skillet and cook for 4-5 minutes until the skin is crispy and golden, then carefully flip and cook the other side for 2-3 minutes until opaque and flaky. Remove fish and keep warm.
- Step 2: In a separate small pan over medium heat, place 1 lemon half cut-side down and char for 3-4 minutes until deeply browned and fragrant. Remove and set aside.
- Step 3: In a small saucepan, melt 2 tbsp unsalted butter over medium heat. Add 2 finely minced shallots and sauté for 2 minutes until translucent and fragrant but not browned.
- Step 4: Add 1/2 cup dry white wine to the shallots and simmer until reduced by half, about 4-5 minutes.
- Step 5: Squeeze the juice of the charred lemon half (about 3 tbsp) into the pan along with 2 tbsp fresh lemon juice and 2 tbsp heavy cream. Stir to combine.
- Step 6: Reduce heat to low and whisk in remaining 4 tbsp cold unsalted butter in small pieces, one at a time, until the sauce thickens and coats the back of a spoon.
- Step 7: Taste and season the beurre blanc with a pinch of salt if needed. Pour sauce over the sea bass fillets and garnish with 1 tbsp chopped fresh parsley before serving.
