O'Hare, 49, has appeared in four episodes of the CBS legal drama as the famously liberal judge. His episode is scheduled to air at the end of January.
"We have missed him a lot," series co-creator and executive producer Robert King tells TVGuide.com. "He doesn't have to wear the burn makeup for this."
King is referring to O'Hare's current series gig on American Horror Story, as Larry "Burn Man" Harvey. He is also set to reprise his role as vampire king Russell Edgington on True Blood when the HBO drama returns for Season 5 next summer.
The Good Wife airs Sundays at 9/8c on CBS.
