01 - Season chicken breasts evenly with kosher salt and freshly ground black pepper on both sides.
02 - Heat olive oil in a large skillet over medium-high heat. Add chicken and sear each side for 4 to 5 minutes until golden brown and cooked through. Remove chicken and keep warm tented with foil.
03 - Reduce heat to medium. In the same skillet, sauté minced garlic for about 30 seconds until fragrant.
04 - Add fresh baby spinach and stir until wilted, approximately 2 minutes. Incorporate quartered artichoke hearts and combine thoroughly.
05 - Pour in heavy cream and low-sodium chicken broth. Bring mixture to a gentle simmer.
06 - Stir in grated Parmesan, dried Italian seasoning, and crushed red pepper flakes if using. Cook and stir until cheese melts and sauce slightly thickens, about 3 minutes.
07 - Nestle seared chicken back into the skillet sauce. Simmer for 2 to 3 minutes, spooning sauce over chicken until heated through.
08 - Plate immediately, garnished with additional Parmesan if desired.
