Begin by seasoning both sides of the chicken breasts generously with salt, pepper, and Italian seasoning. This will enhance the flavor of the chicken.
In a large skillet, heat the olive oil over medium-high heat. Once the oil is shimmering and hot, carefully add the seasoned chicken breasts. Sear them for approximately 5-7 minutes per side, or until they are cooked through (internal temperature reaches 165°F) and nicely golden brown. Once done, remove the chicken from the skillet and place it on a plate; cover to keep warm.
In the same skillet, lower the heat to medium and add the minced garlic. Sauté the garlic for about 30 seconds, stirring frequently to prevent burning, until it becomes fragrant and lightly golden.
Next, add the halved cherry tomatoes to the skillet. Cook for an additional 2-3 minutes, stirring gently, until the tomatoes begin to soften and burst, releasing their juices.
Stir in the fresh baby spinach and continue to cook until it is wilted, about 2 minutes.
Carefully pour in the heavy cream, stirring gently to combine. Bring the mixture to a gentle simmer. Gradually add the grated Parmesan cheese, stirring until it melts completely and creates a smooth, creamy sauce.
Return the seared chicken breasts to the skillet, allowing them to soak in the rich creamy sauce. Let the dish simmer together for an additional 3-5 minutes to meld the flavors.
Before serving, taste the sauce and adjust the seasoning with more salt and freshly cracked pepper if needed.
For a finishing touch, garnish your creamy garlic Tuscan chicken with fresh basil leaves right before serving.
