Dyche guided the Clarets back into the top flight with a second-placed finish in the Sky Bet Championship.
As a result he and his coaching staff have been handed new deals.
"On the subject of key signings we are very pleased to announce that we have agreed new and improved contracts with Sean Dyche and his staff and we thank them all for their hard work," said co-chairmen John Banaszkiewicz and Mike Garlick in a letter to fans.
"This is in addition to the other key 'signings' we have already made in securing the services of some of our current players under new contracts, including, of course, Kieran Trippier and Danny Lafferty.
"We will continue to invest in the recruitment, sports science and scouting that has been so important to us over the years, to ensure we continue to build on this prolific pipeline of players into the future."
Burnley will kick-off the new season at home to Chelsea and by the time Jose Mourinho's side arrive Turf Moor will look slightly different from the last time they were in the top flight in 2010.
"We are in the process of upgrading facilities at Turf Moor as part of our Premier League obligations and also to deliver better facilities for the fans," added the chairman.
"Part of these plans include making the ground a more intimidating place for visitors and we are working on ideas to help generate a big atmosphere and help give the team a boost.
"We are also improving facilities for the playing and coaching staff at Gawthorpe, where we are looking to develop more pitches for our current and future players.
"We at the club are working 24/7 to have everything in place, from our playing staff to facilities, in time for the start of the coming season.
"We know that every Clarets player will wear the shirt with pride as we go up against some of the biggest clubs in the world and are working hard to identify the most suitable transfer targets to be assets for the club in the long term."
