Verdier specialised in history painting and religious subjects. He often worked with red chalk or grey washes to create a sense of volume. His work avoids the excessive ornamentation seen in later Rococo art. In pieces such as Scene from Ancient History: Siege of a Walled City and Saint Anatolia, he uses clear anatomical structures and balanced compositions. He focused on the clarity of the narrative. His figures possess a sculptural quality that suggests a study of classical reliefs and ancient statuary.

Modern collectors value Verdier for the architectural quality of his compositions. His drawings and prints offer a window into the formal logic of seventeenth-century French design. The monochromatic nature of many of his sketches makes them easy to integrate into contemporary interiors. These works provide a sense of historical depth without overcomplicating a room. They appeal to those who appreciate the disciplined draughtsmanship of the French Academic tradition.
