01 - Pat chicken breasts dry and evenly season both sides with salt and black pepper.
02 - Heat olive oil in a large skillet over medium-high heat. Add chicken breasts and sear each side for 4 to 5 minutes until golden brown. Remove chicken and set aside.
03 - Reduce heat to medium and add butter to the same skillet. When melted, add minced garlic and sauté for 1 minute until fragrant.
04 - Stir in heavy cream, chicken broth, Parmesan cheese, Dijon mustard, and Italian herbs. Simmer for 2 to 3 minutes, stirring frequently, until sauce slightly thickens.
05 - Add chopped spinach and artichoke hearts to the sauce. Cook for 2 to 3 minutes until spinach wilts.
06 - Return chicken breasts to skillet, nestling them into the sauce. Spoon sauce over top. Reduce heat to low, cover, and simmer gently for 8 to 10 minutes until chicken reaches an internal temperature of 165°F.
07 - Optionally garnish with chopped fresh parsley. Serve immediately while hot.
