Ingredients

Instructions

  1. Step 1: Pat dry 4 Chilean sea bass fillets and season both sides with 1 tsp salt and 1 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large non-stick skillet over medium-high heat. Add the fillets skin-side down and cook for 4 minutes until the skin turns golden and crisp, then flip and cook another 3 minutes until opaque and flaky. Remove and keep warm.
  3. Step 3: In the same skillet, reduce heat to medium and add 2 tbsp minced shallots. Sauté for 2 minutes until translucent.
  4. Step 4: Pour in 1/2 cup white wine and add 1/4 tsp saffron threads. Simmer for 3 minutes until reduced by half.
  5. Step 5: Stir in 1/4 cup heavy cream and simmer for 1 minute.
  6. Step 6: Remove from heat and whisk in 6 tbsp cold cubed unsalted butter gradually until the sauce is smooth and emulsified.
  7. Step 7: Finish with 1 tbsp lemon juice and season with salt and pepper to taste. Spoon the saffron beurre blanc over the sea bass fillets and serve immediately.
