An expandable food carton expands to a non-trapezoidal shape when in an open and expanded state. The expanded state creates a wider top opening which provides a larger access to the interior of the package and thus to the food product. The expandable carton has a bottom end with upstanding side panels therefrom, where each side panel has at least one score line that extends between an upper end region and a lower end region. The carton has a top flap attached at an upper end of each side panel, each top flap also having a score line that extends longitudinally between an upper end region and a lower end region at a midpoint region. Upon shifting the carton into the expanded state, the side panels of the carton shift outward along their respective score lines and the top flaps of the carton fold down adjacent respective side panels and shift outward along their respective score lines.
