Season the chicken breasts with salt, pepper, and Italian seasoning on both sides.
In a large skillet, heat the olive oil over medium heat. Add the seasoned chicken breasts and cook for about 6-7 minutes on each side until golden brown and cooked through. Remove the chicken from the skillet and set aside.
In the same skillet, add the minced garlic and sauté for about 1 minute until fragrant.
Add the cherry tomatoes to the skillet and cook for an additional 2-3 minutes, until they start to soften.
Stir in the chopped spinach and cook until it wilts, about 2 minutes.
Lower the heat and pour in the heavy cream, stirring to combine. Add the grated Parmesan cheese and mix until the sauce is creamy and slightly thickened. Adjust seasoning with salt and pepper as needed.
Return the cooked chicken breasts back to the skillet, spooning the creamy sauce over the chicken. Simmer for 2-3 minutes to let the flavors meld.
Serve immediately, garnished with fresh basil leaves for an added burst of flavor.
Notes
Serve with pasta or crusty bread to soak up the sauce.
