Aizawl failed to register a win in their last seven games under Meneses, leading to his sacking yesterday.
The Mizoram side is currently sixth on the league table with 17 points from 13 matches and is already out of reckoning for the title.
"Aizawl Football Club is delighted to announce the appointment of Santosh Kashyap as the new Head Coach for the senior team. Welcome Coach Kashyap, and all the best!" the club announced on its Twitter handle.
The 51-year-old Kashyap, an AFC pro licence holder, had coached some of the big clubs in the past like Air India, Mohun Bagan, Salgaocar, Rangdajied United and Royal Wahingdoh.
His last assignment was with Mumbai FC in the 2016-17 season of the I-League.
Kashyap will arrive in Aizawl with five games remaining to turn around their fortunes in this season. The Reds play Indian Arrows in their next fixture on February 16.
"It is a proud moment for me. Joining a club in the middle of the season is a big challenge for me as well, so I will use my experience to try and do something great for the club," Kashyap said.
"We will plan one match at a time, and with the help of the fans and the management we will give our best to put the club in a better atmosphere.
