Ingredients

For the Salmon

4 salmon fillets (skin on or off, about 6 oz each)
Salt and freshly ground black pepper, to taste
½ teaspoon paprika
1 tablespoon olive oil
1 tablespoon unsalted butter

For the Sauce

2 tablespoons unsalted butter
4–5 cloves garlic, minced
8 oz mushrooms, sliced (button or cremini)
1 cup heavy cream
½ cup chicken or vegetable broth
½ cup freshly grated Parmesan cheese
½ teaspoon Italian seasoning
Salt and pepper, to taste

Vegetables

3 cups fresh spinach

Optional Garnish

Fresh parsley or thyme
Lemon wedges

Instructions

1. Season & Sear the Salmon

Pat the salmon dry with paper towels and season both sides with salt, pepper, and paprika.

Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Place salmon fillets in the pan (skin-side down if using skin). Sear for 4–5 minutes per side until golden and just cooked through. Remove salmon from the pan and set aside.

2. Cook the Mushrooms

In the same skillet, melt 2 tablespoons butter. Add sliced mushrooms and cook for 4–5 minutes until softened and lightly browned. Season lightly with salt and pepper.

3. Add Garlic

Stir in minced garlic and cook for 30 seconds until fragrant. Be careful not to burn the garlic.

4. Make the Creamy Sauce

Pour in chicken broth and simmer for 2 minutes, scraping up any flavorful bits from the pan. Add heavy cream, Italian seasoning, and Parmesan cheese. Stir and let the sauce simmer gently for 3–4 minutes until slightly thickened.

5. Add Spinach

Add spinach to the skillet and stir until just wilted, about 1 minute. Taste the sauce and adjust seasoning as needed.

6. Return the Salmon

Place the salmon back into the pan, spooning sauce over the fillets. Let everything simmer together for 2–3 minutes to meld flavors.

Tips for Perfect Results

Do not overcook the salmon; it should flake easily but remain moist inside.
Use freshly grated Parmesan for a smooth sauce.
If the sauce thickens too much, add a splash of broth or cream.
Cremini mushrooms add deeper flavor, but any mushrooms work well.

Serving Suggestions

Serve this creamy garlic butter salmon with:

Steamed rice or mashed potatoes
Pasta or creamy polenta
Crusty bread to soak up the sauce

A fresh green salad or roasted vegetables makes a perfect side.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 2 days.
Reheat gently on the stovetop over low heat to avoid separating the sauce.
