01 - Sprinkle both sides of the chicken breasts with kosher salt and black pepper.
02 - Heat olive oil in a large skillet over medium-high heat. Cook chicken for 4 to 5 minutes on each side until golden and just cooked through. Remove and tent with foil.
03 - Lower heat to medium. Add minced garlic to the skillet and sauté for 30 seconds until fragrant.
04 - Add fresh spinach to the skillet and stir until wilted, about 2 minutes. Add quartered artichoke hearts and stir to combine.
05 - Pour in heavy cream and chicken broth. Bring to a gentle simmer, then add Parmesan cheese, Italian seasoning, and crushed red pepper flakes if desired.
06 - Stir continuously until the cheese melts and the sauce slightly thickens, approximately 3 minutes.
07 - Nestle the chicken breasts back into the sauce. Simmer for 2 to 3 minutes, spooning sauce over the chicken until heated through.
08 - Plate the chicken and sauce. Optionally garnish with additional Parmesan cheese. Serve immediately.
