01 - Season the chicken breasts evenly with salt and black pepper on both sides.
02 - Heat olive oil in a large skillet over medium-high heat. Add chicken breasts and sear for 5 to 6 minutes per side until golden brown and cooked through. Transfer to a plate and cover loosely to keep warm.
03 - In the same skillet, add minced garlic and sauté for 1 minute until fragrant, being careful not to burn.
04 - Add cherry tomatoes and cook for 2 to 3 minutes until slightly softened and beginning to release their juices.
05 - Pour in chicken broth and scrape up any browned bits from the bottom of the skillet. Add heavy cream, Parmesan cheese, and Italian herbs. Stir well and bring to a gentle simmer.
06 - Add fresh spinach and cook until just wilted, about 2 minutes, stirring occasionally.
07 - Return chicken breasts to the skillet, spoon sauce generously over the top, and simmer for another 2 to 3 minutes until heated through.
08 - Taste the sauce and adjust seasoning if needed. Serve hot, garnished with additional Parmesan cheese if desired.
