Louise Élisabeth was able to leave Spain in 1748 when her husband was created Duke of Parma thanks to the Treaty of Aix-la-Chapelle (1748) which ended the War of the Austrian Succession. At Louis XV's instigation, Philip was given Parma as Louise Élisabeth had frequently asked him to bestow territory on her husband. En route to Parma, Louise Élisabeth went to Versailles arriving there in December 1748. During her stay she became acquainted with Madame de Pompadour. She arrived in Parma in October 1749 where she imported French court manners and "cuisine". She also redecorated the Ducal Palace of Colorno in the French style.
