Director of rugby Mark McCall, head coach Andy Farrell, technical director Brendan Venter, defence and forwards coach Paul Gustard, forwards coach Alex Sanderson and kicking coach Dan Vickers have all committed to the club.
And club chairman Nigel Wray believes the news is a massive boost for the club heading into the new campaign.
Wray said: "Not only do we have a talented group of coaches... they are also an exceptional group of people and that is just as important.
"We have stability within our coaching and playing staff, and they work fantastically hard for each other, which makes me so excited about the future."
Farrell, Gustard and Sanderson all joined the backroom staff after spells playing for Sarries, while Vickers made the move from Bath in 2006.
Former Ulster chief McCall replaced Venter as director of rugby at the turn of the year after initially arriving as head coach in 2009.
Venter guided Sarries to the Premiership final in 2010 before taking up the role as technical director so he could spend more time with his family.
