Begin by seasoning the chicken breasts generously with salt, black pepper, and Italian seasoning on both sides to infuse them with flavor.
In a large skillet, heat the olive oil over medium heat. Once the oil is shimmering, carefully add the seasoned chicken breasts. Cook for approximately 6-7 minutes on each side, or until they are golden brown and cooked through. To ensure even cooking, check that the internal temperature reaches 165°F (75°C). Once cooked, remove the chicken from the skillet and set it aside on a plate to rest.
In the same skillet, add the minced garlic and sauté for about 1 minute. Stir continuously until the garlic becomes fragrant and slightly golden—be careful not to let it burn.
Introduce the halved cherry tomatoes to the skillet and cook for an additional 2-3 minutes, stirring occasionally, until they begin to soften and burst, releasing their juices.
Add the fresh spinach to the mixture, stirring it in until it wilts—this should take about 2 minutes. The vibrant color of the spinach will contrast beautifully with the other ingredients.
Pour in the heavy cream and stir to combine all the components. Allow the mixture to come to a gentle simmer, enhancing the flavors together.
Gradually add the grated Parmesan cheese, stirring constantly until it melts completely and the sauce thickens slightly. Taste the sauce and adjust the seasoning with additional salt and pepper if needed.
Carefully return the chicken to the skillet, spooning the rich and creamy sauce over each piece to ensure it's well coated. Allow it to simmer gently for another 2-3 minutes, just enough to heat the chicken through again.
Before serving, garnish with a few fresh basil leaves for a pop of color and additional flavor.
