The 28-year-old joined the southern outfit in 2008 and has since made 164 appearances, scoring 14 goals.
The club did not disclose the length of the new deal.
"I am pleased that we have once again reached agreement," Schuster told the club's official website.
"I have experienced in Freiburg five-and-a-half great years as a professional and find the club to be my footballing home."
