Pat salmon fillets dry and season thoroughly on all sides with salt, black pepper, and dried thyme.

Heat olive oil in a large skillet over medium-high heat. Sear salmon fillets flesh-side down for 3–4 minutes, flip, and cook another 3–4 minutes until opaque and just cooked through. Transfer fillets to a plate and set aside.

In the same skillet, add sliced mushrooms and cook over medium heat until browned and their liquid evaporates, about 3–4 minutes.

Add minced garlic to the mushrooms, stirring constantly for 1 minute until fragrant. Add fresh spinach and cook for 1–2 minutes until wilted.

Pour in the heavy cream and bring to a gentle simmer. Stir in grated Parmesan cheese until melted and sauce is smooth. Adjust seasoning with salt and pepper as needed.

Return salmon fillets to the skillet, nestling them into the sauce and vegetables. Spoon creamy sauce over each fillet and cook for 1 minute to gently reheat.

Sprinkle with chopped parsley if desired and serve immediately.
