In a large skillet, warm the olive oil over medium heat until shimmering. Place the salmon fillets in the skillet, skin-side down. Season generously with salt and freshly ground black pepper. Sear the salmon for about 4-5 minutes per side, or until the fish is opaque and golden brown. Once cooked to your liking, carefully remove the fillets from the skillet and place them on a warm plate; set aside.
In the same skillet, add the minced garlic and sauté for approximately 30 seconds, stirring constantly until fragrant—be cautious not to burn the garlic.
Introduce the halved cherry tomatoes to the skillet. Cook for about 3-4 minutes, allowing them to soften and pop, releasing their juices into the pan.
Stir in the fresh spinach leaves, cooking until they are just wilted—this should take about 1-2 minutes.
Pour in the heavy cream and bring the mixture to a gentle simmer. Reduce the heat, then add the freshly grated Parmesan cheese and dried Italian herbs. Stir thoroughly until the cheese is melted and the sauce is beautifully creamy.
Carefully return the seared salmon fillets to the skillet, spooning the luxurious creamy sauce over them. Allow everything to simmer together for an additional 2-3 minutes for the flavors to meld.
Taste the sauce and adjust the seasoning with more salt and freshly ground black pepper, if desired.
Serve your creamy Tuscan salmon on warm plates, generously topped with the sauce and garnished with torn fresh basil leaves for a vibrant touch.
Notes
For an elegant touch, serve over creamy mashed potatoes or alongside al dente pasta.
