Instructions
- Step 1: Pat dry 4 Chilean sea bass fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper.
- Step 2: Heat 2 tbsp unsalted butter in a large skillet over medium-high heat. Add the fillets skin-side down and cook for 5-6 minutes until the skin is crisp and golden. Flip and cook for another 3-4 minutes until the fish is opaque and flakes easily. Remove fillets and keep warm.
- Step 3: In the same skillet, add 2 tbsp finely minced shallots and sauté over medium heat for 2 minutes until softened and fragrant.
- Step 4: Pour in 1/4 cup dry white wine and simmer until reduced by half, about 3 minutes.
- Step 5: Stir in 2 tbsp fresh lemon juice, 2 tbsp fresh orange juice, and 2 tbsp heavy cream. Slowly whisk in the remaining 4 tbsp unsalted butter in small pieces, stirring constantly until the sauce is smooth and slightly thickened.
- Step 6: Season the sauce with salt to taste and stir in 1 tbsp chopped fresh parsley.
- Step 7: Spoon the citrus beurre blanc over the sea bass fillets and serve immediately with steamed vegetables or rice.

How do I store leftover Pan-Seared Chilean Sea Bass with Citrus Beurre Blanc?
Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish).
