As revealed in SportTimes yesterday, the midfielder has put pen to paper on an extended deal that will see him remain at Firhill until May 2017.
It has been a rapid rise to prominence for Fraser, who agreed a deal with Bolton following his release from Hamilton Accies last season and moved to Thistle on loan before signing a permanent move in January.
The 19-year-old was a key part of the Jags squad that retained their place in the SPFL Premiership for next season, with his superb strike in the 4-2 win over Hearts in the penultimate 90 minutes undoubtedly the highlight of his first season at Firhill.
Fraser follows midfield partner Stuart Bannigan in committing his long-term future to Alan Archibald's team this summer and admits he is loving life in red and yellow as he sets his sights higher.
He said: "It is brilliant [at Thistle]. I have enjoyed the season that I have spent here and I want to stay for longer.
"I want to stay in the team and help us push for the top six. Hopefully I can remain in the team as well and score goals.
"I have improved massively this season. Even the way I prepare before games and the way I do things, I feel I have matured.
"There is still a lot to come from me and I think I have yet to reach the level I know that I can play at.
"I want to add more goals to my game and get better with each game that I play.
"We deserve to be [in the Premiership] so everyone is happy.
"It was great knowing we didn't have to come back for the play-offs."
