CBS announced that it had renewed The Mentalist for a sixth season on March 27, 2013. It was revealed in July 2013 that the mystery of Red John will be revealed before the end of 2013.
On August 7, 2013, it was announced that characters Wayne Rigsby and Grace Van Pelt, played by Owain Yeoman and Amanda Righetti, both of whom had been on the series since the first episode, would be leaving. Emily Swallow and Rockmond Dunbar were cast as Kim Fischer and Dennis Abbott, two recurring characters with the potential to become series regulars. Dunbar was promoted to series regular on October 18, 2013, three weeks before his first episode had been broadcast. On November 15, Swallow was likewise promoted to series regular before her first appearance was aired.
Righetti and Yeoman's final episode, "White as the Driven Snow", aired on March 23, 2014.
The first episode of the season "The Desert Rose" was filmed in Bombay Beach, California. The production team created a sign for the fictional "Borrego Gas Diner" to stand-in for the local bar and restaurant Ski Inn.
