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 nonstick skillet over medium-high heat.
  2. Step 2: Place fillets skin-side down in the skillet and cook for 4-5 minutes without moving until skin is crisp. Flip fillets carefully and cook for an additional 2 minutes until fish is opaque and flakes easily.
  3. Step 3: Remove trout to a warm plate. In the same skillet, add 2 tbsp unsalted butter and 2 minced garlic cloves. Sauté for 1 minute until fragrant, then add 8 oz sliced mixed forest mushrooms and cook for 5-6 minutes until browned and tender.
  4. Step 4: Meanwhile, in a small bowl, mix 2 tbsp softened unsalted butter with 2 tbsp chopped parsley, 1 tbsp chopped chives, and 1 tbsp lemon juice.
  5. Step 5: Serve trout fillets topped with a dollop of the fresh herb butter alongside the sautéed mushrooms.
