Instructions
- Step 1: Pat dry 4 trout fillets and season both sides with salt and black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat. Place the trout skin-side down and cook for 4-5 minutes until the skin is crisp and golden, then carefully flip and cook for another 2 minutes until just cooked through. Remove trout and keep warm.
- Step 2: In the same skillet, add 1 tbsp olive oil and sauté 2 minced shallots and 2 minced garlic cloves for 2 minutes until fragrant and translucent. Add 8 oz sliced cremini mushrooms and cook for 5-6 minutes until softened and browned.
- Step 3: Pour in 1/4 cup dry white wine and simmer for 2 minutes until reduced by half. Stir in 4 tbsp unsalted butter, 2 tsp fresh thyme leaves, 2 tbsp chopped parsley, and 1 tbsp lemon juice until melted and the sauce thickens slightly, coating the mushrooms.
- Step 4: Spoon the mushroom sauté over the trout fillets and serve immediately, garnished with extra parsley if desired.
