The Ghanaian teenager will be aiming to make a quick mark with the senior side of the Bebbi's as he spent most of his time with the reserve side of the club.
Essiam made four Swiss Super League appearances for the Bebbi's last season and also featured as the club reached the semi-finals of the UEFA Europa Conference League.
Basel have lined up a couple of friendlies before the start of the 2023/24 league season. They will face Portuguese giants Benfica on Sunday in a pre-season friendly match, with Essiam expected to feature in that game.
In January 2022, Essiam made a switch to Switzerland to join Basel from Berekum Chelsea.
