Ingredients

Instructions

  1. Step 1: Pat 4 trout fillets dry and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering.
  2. Step 2: Place the trout fillets skin-side down in the skillet and cook for 4-5 minutes until the skin is crisp and golden. Flip and cook an additional 2-3 minutes until the fish flakes easily.
  3. Step 3: Remove the trout from the skillet and set aside on a warm plate. Reduce heat to medium and add 6 tbsp unsalted butter to the same skillet.
  4. Step 4: Cook the butter, stirring occasionally, for 3-4 minutes until it turns golden brown and emits a nutty aroma.
  5. Step 5: Stir in 2 tbsp drained capers and 2 tbsp fresh lemon juice, cooking for 30 seconds until fragrant and the sauce thickens slightly.
  6. Step 6: Spoon the lemon-caper brown butter sauce over the trout fillets and garnish with 2 tbsp chopped fresh parsley before serving.

How do I store leftover Pan-Seared Trout with Lemon-Caper Brown Butter Sauce?

Can I substitute ingredients in Pan-Seared Trout with Lemon-Caper Brown Butter Sauce?

How do I scale Pan-Seared Trout with Lemon-Caper Brown Butter Sauce 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.
