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 sear for 4 to 5 minutes per side until golden brown. Remove chicken and set aside.
03 - Reduce heat to medium. 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 dried Italian herbs. Simmer for 2 to 3 minutes, stirring frequently, until sauce slightly thickens.
05 - Incorporate spinach and artichoke hearts into the sauce. Cook for 2 to 3 minutes until spinach wilts.
06 - Nestle the seared chicken breasts back into the skillet, spoon sauce over them. Reduce heat to low, cover, and simmer for 8 to 10 minutes, or until internal temperature reaches 165°F.
07 - Sprinkle with fresh parsley if desired. Serve immediately.
