Prepare your ingredients by gathering all necessary items.
In a large skillet over medium heat, melt the butter. Add minced garlic and sauté until fragrant, about one minute.
Carefully place the salmon fillets in the skillet skin-side down. Season with salt and pepper and cook for about four minutes per side until golden brown.
Remove the salmon from the skillet. In the same skillet, add heavy cream, sun-dried tomatoes, and dried Italian herbs. Simmer for three minutes while stirring occasionally.
Stir in fresh spinach until wilted, about two minutes.
Return the cooked salmon to the skillet, drizzling with any remaining butter and spooning the sauce on top. Heat through before serving.
