- Heavy Whipping Cream: Creates a silky, rich sauce that clings to the salmon and vegetables.
- Garlic & Butter: Unsalted butter and plenty of minced garlic cloves provide the aromatic base.

Step-by-Step Instructions
- Prep the Salmon: Pat 4 salmon fillets (about 6 oz each) thoroughly dry using paper towels. Season both sides with 1 teaspoon kosher salt, 1/2 teaspoon freshly cracked black pepper, and 1/2 teaspoon garlic powder.
- Sear the Salmon Fillets: Heat 1 tablespoon extra virgin olive oil and 1 tablespoon unsalted butter in a large skillet over medium-high heat. Add the salmon fillets flesh-side down and sear undisturbed for 4 minutes until a deep golden crust forms. Flip and cook for another 2 to 3 minutes until nearly cooked through. Transfer salmon to a warm plate and set aside.
- Sauté the Mushrooms: In the same skillet over medium heat, melt 2 tablespoons of unsalted butter. Add 8 oz of sliced cremini mushrooms and cook for 4 to 5 minutes until browned and tender.
- Add Garlic & Deglaze: Add 4 minced garlic cloves and cook for 1 minute until fragrant. Pour in 1/3 cup of dry white wine or chicken broth to deglaze the skillet, scraping up any browned bits stuck to the bottom with a wooden spoon. Allow the liquid to reduce by half (about 2 minutes).
- Build the Cream Sauce: Reduce heat to medium-low. Stir in 1 cup of heavy whipping cream and bring to a gentle simmer for 2 to 3 minutes until slightly thickened. Whisk in 1/2 cup of freshly grated Parmesan cheese until smooth and fully melted.
- Wilt the Spinach: Add 3 cups of fresh baby spinach into the skillet. Stir gently for 1 to 2 minutes until the spinach is completely wilted into the creamy mushroom sauce. Taste and adjust seasoning with salt and pepper.
- Reassemble and Serve: Return the seared salmon fillets back into the skillet, nesting them gently on top of the creamy spinach and mushroom sauce. Spoon the warm sauce over the fillets. Garnish with chopped fresh parsley and serve hot.Tip: Simmering the cream sauce on low heat after adding Parmesan prevents it from separating or becoming oily.

Storage & Reheating
Store leftover salmon with sauce in an airtight container in the refrigerator for up to 2 days.
Reheat gently in a covered skillet over low heat with a small splash of milk or cream for 3 to 5 minutes until warmed through. Avoid microwaving on high heat to keep the salmon from drying out and the cream sauce from breaking.

Frequently Asked Questions
Can I use frozen spinach instead of fresh? Yes, but thaw 1 cup of frozen chopped spinach completely and squeeze out all excess liquid using a clean kitchen towel before adding it to the cream sauce.
What white wine works best for cooking salmon? Use a dry, crisp white wine such as Pinot Grigio, Sauvignon Blanc, or Unoaked Chardonnay. Avoid sweet dessert wines like Riesling or Moscato.
How do I prevent my salmon from sticking to the skillet? Make sure the skillet and oil are hot before adding the fish, and pat the salmon fillets dry before seasoning.
