Instructions

  1. Step 1: Pat dry 4 steelhead trout fillets (6 oz each) and season both sides evenly with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat until shimmering. Place the fillets skin-side down and cook for 4-5 minutes without moving until the skin is crisp and golden.
  3. Step 3: Carefully flip the fillets over and cook for an additional 2-3 minutes until the fish flakes easily with a fork. Remove fillets to a serving plate.
  4. Step 4: Reduce heat to low, add 4 tbsp unsalted butter to the skillet and let melt. Stir in 2 tbsp fresh lemon juice, 1 tsp lemon zest, 2 tbsp finely chopped parsley, and 1 tbsp finely chopped dill. Let the sauce cook for 1 minute until fragrant and slightly thickened.
  5. Step 5: Spoon the herb lemon butter sauce generously over the trout fillets and serve immediately with your choice of side.
