01 - Pat chicken breasts dry and evenly season both sides with Italian seasoning, salt, black pepper, and paprika.
02 - Heat olive oil and butter in a large skillet over medium-high heat. Add chicken breasts and sear for 5 to 6 minutes per side until golden brown and fully cooked. Remove and keep warm.
03 - Reduce heat to medium in the same skillet. Add minced garlic and sauté for 1 minute until aromatic.
04 - Pour in heavy cream and chicken broth to deglaze the pan, stirring to lift browned bits. Bring mixture to a gentle simmer.

06 - Add fresh baby spinach and cook for 1 to 2 minutes until wilted.
07 - Return the chicken breasts to the skillet, spoon sauce over them, and simmer for 2 to 3 minutes to heat through.
08 - Plate the chicken and sauce, garnishing with fresh basil and extra Parmesan if desired.
