01 - Season both sides of each chicken breast thoroughly with salt and black pepper, ensuring even coverage.
02 - Heat olive oil in a large skillet over medium-high heat. Place chicken breasts in the hot pan and sear for 5–6 minutes per side until golden brown and cooked through. Transfer to a plate and cover loosely with foil to retain warmth.
03 - In the same skillet, add minced garlic and sauté for approximately 1 minute until fragrant, being careful not to burn.
04 - Add halved cherry tomatoes to the skillet and cook for 2–3 minutes until they begin to soften and release some juices.
05 - Pour in chicken broth and deglaze the pan, scraping up any browned bits from the bottom. Add heavy cream, grated Parmesan, and Italian herbs. Stir continuously to combine and bring to a gentle simmer.
06 - Add fresh baby spinach to the simmering sauce and cook for about 2 minutes until just wilted, stirring gently.
07 - Return chicken breasts to the skillet, spooning the sauce generously over the top. Simmer for an additional 2–3 minutes until everything is heated through. Taste and adjust seasoning as needed before serving hot.
