Recipe: Garlic Butter Salmon with Spinach & Mushrooms in Creamy Sauce

Ingredients

4 salmon fillets (skin-on or skinless, about 6 oz each)
2 tablespoons olive oil
3 tablespoons unsalted butter
3 garlic cloves, minced
1 cup mushrooms, sliced (button or cremini)
2 cups fresh spinach leaves
1 cup heavy cream
½ cup chicken or vegetable broth
½ cup grated Parmesan cheese
1 teaspoon Italian seasoning
Salt and black pepper, to taste
Fresh parsley, for garnish

Instructions

Season and Sear the Salmon – Pat salmon fillets dry and season with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Sear salmon, skin-side down first, for 3–4 minutes per side until golden brown. Remove from the skillet and set aside.
Cook the Mushrooms – In the same pan, melt butter. Add garlic and sauté until fragrant (about 30 seconds). Stir in mushrooms and cook until tender and lightly browned.
Make the Creamy Sauce – Pour in broth and heavy cream, stirring to combine. Add Parmesan cheese and Italian seasoning. Simmer until the sauce thickens slightly, about 3–4 minutes.
Add Spinach – Stir in fresh spinach and cook until just wilted.
Return the Salmon – Place salmon fillets back in the skillet. Spoon the creamy garlic butter sauce over the top and let simmer for 2–3 minutes to absorb flavors.
Serve – Garnish with fresh parsley and serve hot with rice, pasta, or roasted vegetables.

Tips and Variations

Low-Carb Option: Serve with cauliflower rice or zucchini noodles instead of pasta.
Extra Flavor: Add sun-dried tomatoes or a splash of white wine to the sauce.
Cheese Lovers: Swap Parmesan for Pecorino Romano or Gruyère for a richer taste.
Spicy Kick: Add red pepper flakes for a hint of heat.
Meal Prep Friendly: Store leftovers in an airtight container and reheat gently for up to 2 days.
