Start by patting the chicken breasts dry with paper towels to ensure browning. Generously season both sides with Italian seasoning, along with sea salt and freshly cracked black pepper for enhanced flavor.
Heat olive oil in a large skillet over medium-high heat. Once hot, add the seasoned chicken breasts carefully. Cook for about 5-7 minutes on each side, or until they are golden brown and reach an internal temperature of 165°F. When done, remove the chicken from the skillet and keep it warm by covering with foil or placing it on a plate.
In the same skillet, reduce the heat to medium and add the minced garlic. Sauté for about 1 minute, stirring frequently until the garlic is fragrant but not browned, as burnt garlic can turn bitter.
Next, toss in the halved cherry tomatoes and fresh spinach leaves. Cook for about 2-3 minutes, stirring occasionally, until the spinach wilts and the tomatoes begin to soften and release their juices.
Slowly pour in the heavy whipping cream, then add the grated Parmesan cheese. Stir well to combine, allowing the cheese to melt into the cream. Let the sauce come to a gentle simmer while continually stirring until it thickens slightly.
Carefully return the cooked chicken to the pan, nestling it among the creamy sauce. Let it simmer for another 3-4 minutes, allowing the chicken to absorb the rich flavors of the sauce.
Remove from heat and enhance with a sprinkle of fresh basil on top. Serve the creamy garlic Tuscan chicken warm, generously spooning extra sauce over the chicken for added deliciousness.
Notes
Serve with garlic bread or over pasta for a complete meal.
