An onion chopper includes a container having a bottom and a plurality of sidewalls extending upwardly and terminating in a rim. A lid is attached to the container at a pivot location for movement between a closed position adjacent the rim and an open position pivoted away from the rim. A tray is removably supported atop the container, and defines a central opening positioned between a forward end and a rearward end. A spiralizer insert is removably attached to the tray within the central opening, the spiralizer insert having a central spindle and a blade extending radially outward from the central spindle.
