Instructions

  1. Step 1: Pat dry 4 Chilean sea bass fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper.
  2. 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.
  3. Step 3: In the same skillet, add 2 tbsp finely minced shallots and sauté over medium heat for 2 minutes until softened and fragrant.
  4. Step 4: Pour in 1/4 cup dry white wine and simmer until reduced by half, about 3 minutes.
  5. 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.
  6. Step 6: Season the sauce with salt to taste and stir in 1 tbsp chopped fresh parsley.
  7. Step 7: Spoon the citrus beurre blanc over the sea bass fillets and serve immediately with steamed vegetables or rice.

Frequently asked questions

How long does Pan-Seared Chilean Sea Bass with Citrus Beurre Blanc take to make?

Total time is about 25 minutes (10 min prep + 15 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

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). Store any fresh salsa or citrus-based garnish in a separate container — it keeps for up to 2 days.

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Pan-Seared Chilean Sea Bass with Citrus Beurre Blanc for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
