Niasse was signed by Roberto Martinez in January 2016 from Lokomotiv Moscow and has had a roller-coaster Everton career, which has seen him dip drastically in and out of favour on occasion.
Martina joined the Blues in the summer of 2017 in a free transfer from Southampton, and was used primarily as left-back cover during the following term before falling out-of-favour.
Earlier this week, Maarten Stekelenburg was handed an extension until the end of the season, before leaving the club to join Ajax at the end of the term.
Everton's under-23s also confirmed departures with Morgan Feeney, Alex Denny, Matty Foulds, Manasse Mampala and Korede Adedoyin all to be released - while Kieran Phillips will complete his loan spell with Huddersfield before leaving the Blues.
Nathangelo Markelo and Con Ouzounidis have been offered new deals.
