Season both sides of chicken with salt, Italian seasoning, pepper, and paprika. Place in slow cooker.
In a medium mixing bowl, stir together heavy cream, chicken broth, garlic, pepper, Parmesan, and sun-dried tomatoes or peppers until combined. Pour on top of chicken.
Cook on low for 1.5-3 hours or until chicken is cooked to 165° F.
Once cooked through, remove chicken and set aside. Add spinach to slow cooker, stir, and cover.
Meanwhile, in a separate pot, boil pasta in water as directed on the packaging. Strain and add to the sauce. Stir until sauce completely coats the noodles.
Serve with chicken and enjoy!
