FC Hasental was founded by Gerd Kleemann, Eric Warner, Justin Carpenter, and Robbert-Jan Matthee.
The following season Hasental introduced their reserve team, who won the TCSL League Championship, beating cup holders Crown & Anchor Lions with a 1–1 draw in May 2009.
FC Hasental's reserve team won the TCSL Charity Shield in 2009/10, but relinquished their hold of the League Cup.
The club entered the Lamar Hunt US Open Cup in 2009 and 2010, through the Region IV USASA qualification tournament, but failed to qualify on both occasions.
Also in 2010, Hasental enjoyed victories over Hollywood United, Orange County Blue Star, Los Angeles Blues and PSA Elite, and tied 1–1 with Major League Soccer side Chivas USA, while the Hasental U23's lost 5–0 to the same Chivas USA team, and lost to the Maryland Bays in the U23 National Championship semi finals, in Overland Park, Kansas.
