The 37-year-old made her decisive move with around 20 kilometres left, breaking away from a lead group that included defending champion Chantal van den Broek-Blaak (Boels–Dolmans) and her team-mate Gracie Elvin.
Van Vleuten opened up a gap of 15 seconds after descending off the Muur-Kapelmuur, and that lead only widened as she eventually crossed the finish line.
Marta Bastianelli finished second, with Floortje Mackaij third.
