Season the Salmon
Pat the salmon fillets dry with a paper towel and season with salt and pepper on both sides.

Sear the Salmon
Heat olive oil and butter in a large skillet over medium-high heat. Place salmon fillets skin-side down and cook for 4–5 minutes per side, or until golden and cooked through. Remove from skillet and set aside.

Sauté Garlic and Mushrooms
In the same skillet, add olive oil if needed. Add garlic and sauté for 30 seconds until fragrant. Stir in mushrooms and cook for 4–5 minutes until browned and tender.

Add Spinach
Stir in spinach and cook for about 2 minutes until wilted.

Create the Creamy Sauce
Add Italian seasoning, red pepper flakes, heavy cream, chicken broth, and Parmesan cheese. Stir and simmer for 3–5 minutes until the sauce thickens slightly.

Return Salmon to Skillet
Place salmon back into the pan, spoon sauce over the top, and let it simmer for another 1–2 minutes.

Garnish and Serve
Sprinkle with chopped parsley and serve hot with your favorite sides.
