01 - Pat chicken breasts dry and season both sides evenly with salt and black pepper.
02 - Heat olive oil in a large skillet over medium-high heat. Add chicken breasts and cook 4-5 minutes per side until golden brown. Remove chicken and set aside.
03 - Reduce heat to medium and melt butter in the same skillet. 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 2-3 minutes, stirring frequently, until sauce thickens slightly.
05 - Incorporate spinach and artichoke hearts into the sauce. Cook for 2-3 minutes until spinach wilts.
06 - Return chicken breasts to the skillet, nestling them into the sauce. Spoon sauce over chicken. Lower heat to low, cover, and simmer for 8-10 minutes until chicken reaches 165°F internal temperature.
07 - Optionally, sprinkle with chopped fresh parsley. Serve hot.
