Description

Garlic Butter Salmon with Spinach & Mushrooms in Creamy Sauce is a rich yet simple one-pan dish featuring seared salmon, sautéed mushrooms, and wilted spinach in a creamy garlic-butter sauce.


Ingredients

  • 2 (6 oz) salmon fillets
  • 1 Tbsp olive oil
  • 2 Tbsp butter
  • 8 oz mushrooms, sliced (button or cremini)
  • 3 cloves garlic, minced
  • 2 cups fresh spinach
  • ½ cup heavy cream (or light cream)
  • ¼ cup chicken broth (or wine for deglazing)
  • 1 tsp Dijon mustard (optional for tang)
  • 1 Tbsp fresh lemon juice (optional brightness)
  • Salt & black pepper, to taste
  • Optional: chopped parsley or thyme for garnish

Instructions

  1. Pat salmon fillets dry and season both sides with salt and pepper.
  2. Heat olive oil in a skillet over medium-high heat. Sear salmon skin-side down for 4 minutes, then flip and cook 3–4 more minutes. Remove and set aside.
  3. In the same pan, melt butter. Add mushrooms and cook 3–5 minutes until browned. Add garlic and sauté 30 seconds until fragrant.
  4. Add spinach and cook until wilted, about 1–2 minutes.
  5. Pour in broth and cream, stirring to deglaze. Add Dijon mustard and lemon juice if using. Simmer 2–3 minutes to slightly thicken.
  6. Return salmon to the pan, spooning sauce over fillets. Heat together for 1–2 minutes.
  7. Garnish with parsley or thyme and serve immediately.

Notes

  • Use coconut cream and vegan butter for a dairy-free version.
  • Red pepper flakes add a spicy kick to the sauce.
  • Trout, cod, or halibut can replace salmon.
  • Pairs well with mashed potatoes, rice, or low-carb options like cauliflower rice.
  • Store leftovers for up to 3 days in the fridge or freeze for up to 2 months.
