Instructions

  1. Step 1: Pat dry 4 trout fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large non-stick skillet over medium heat until shimmering.
  2. Step 2: Place the fillets skin-side down in the skillet and cook undisturbed for 4-5 minutes until the skin is crisp and golden. Flip and cook for an additional 2 minutes until just cooked through, then transfer to a warm plate.
  3. Step 3: In the same skillet, reduce heat to low and add 4 tbsp unsalted butter and 2 tbsp finely chopped shallots. Sauté for 2-3 minutes until softened and fragrant.
  4. Step 4: Add 1/4 cup dry white wine and let it reduce by half, then stir in 3 tbsp fresh lemon juice and 2 tbsp chopped parsley. Simmer for 1 minute until the sauce thickens slightly.
  5. Step 5: Spoon the lemon butter sauce over the trout fillets and serve immediately.
