Instructions

  1. Step 1: Pat 4 sea bass fillets dry, then season both sides with salt and pepper.
  2. Step 2: Heat 2 tbsp olive oil in a skillet over medium-high heat until shimmering. Place fillets skin-side down and cook 5-6 minutes until skin is golden and crispy. Flip and cook 3-4 minutes more until cooked through. Transfer to a plate and cover with foil.
  3. Step 3: Add 1 finely chopped shallot to the skillet and cook 2 minutes until softened. Add zest of 1 lemon and cook 1 minute until fragrant.
  4. Step 4: Pour in 1/2 cup white wine, scraping up browned bits, and simmer 3 minutes until reduced by half.
  5. Step 5: Reduce heat to low. Stir in 1/4 cup heavy cream and simmer 2 minutes until slightly thickened. Remove from heat and slowly whisk in 3 tbsp cold unsalted butter, one piece at a time, until glossy and emulsified.
  6. Step 6: Stir in 2 tbsp chopped fresh dill and season with salt and pepper. Pour sauce over sea bass and serve immediately.

Frequently asked questions

How long does Serious Pan-Seared Sea Bass with Lemon-Dill Beurre Blanc take to make?

How do I store leftover Serious Pan-Seared Sea Bass with Lemon-Dill Beurre Blanc?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish).

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 Serious Pan-Seared Sea Bass with Lemon-Dill 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.
