A catering tray is a large, rectangular or circular platter used for serving food at events or gatherings. It is often used by catering companies or restaurants to transport and display appetizers, entrees, and desserts.

To use a catering tray, the food is arranged in an attractive and organized manner on the tray, and then it is transported to the event or served to guests at the location.
