Ingredients
- 4 pieces, 6 oz each, skin on salmon fillets
- 1 tsp salt
- 1 tsp black pepper
- 2 tbsp olive oil
- 2 tbsp unsalted butter
- 8 oz, sliced cremini mushrooms
- 3 minced garlic cloves
- 4 cups baby spinach
- 1/2 cup heavy cream
- 1/4 cup grated Parmesan cheese
- 1 tbsp fresh lemon juice
- 1 tbsp for garnish chopped fresh parsley
Instructions
- Step 1: Pat 4 salmon fillets dry and season both sides with 1 tsp salt and 1 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat.
- Step 2: Place salmon fillets skin-side down and cook for 5-6 minutes without moving until skin is crisp and golden. Flip and cook for 2-3 minutes until salmon is just cooked through. Remove and keep warm.
- Step 3: Reduce heat to medium and add 2 tbsp unsalted butter to the skillet. Add 8 oz sliced cremini mushrooms and sauté for 5 minutes until browned and tender.
- Step 4: Add 3 minced garlic cloves and cook for 1 minute until fragrant. Stir in 4 cups baby spinach and cook until wilted, about 2 minutes.
- Step 5: Pour in 1/2 cup heavy cream and 1/4 cup grated Parmesan cheese, stirring until sauce thickens slightly and coats the mushrooms and spinach, about 3 minutes.
- Step 6: Stir in 1 tbsp fresh lemon juice, season with additional salt and pepper if desired. Spoon sauce over salmon fillets and garnish with 1 tbsp chopped fresh parsley before serving.

How do I store leftover Pan-Seared Salmon with Creamy Spinach and Mushroom Sauce?

Can I substitute ingredients in Pan-Seared Salmon with Creamy Spinach and Mushroom Sauce?
Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut).
