The 'Beez in the Trap' rapper joined American Idol's judging panel in the summer of 2012 along with Mariah Carey and country music star Keith Urban.
In an interview with E! News, Minaj said she is still undecided about another season on the Fox reality competition.
"I don't know, we'll see," Minaj said. "See the thing is, we're only halfway done so, I am absolutely enjoying Idol but I don't know how I'm going to feel at the end of it."
Her tenure on American Idol has arguably been defined by her public feud with fellow judge Mariah Carey.
Minaj recently clarified that she and Carey have put aside any ill will, but she has since insisted that the two will never share the Idol stage for a special performance.
"I don't know. God bless her though… I mean, that'll never happen," she declared.
American Idol airs on Wednesdays and Thursdays on Fox. The show is broadcast on Thursdays and Fridays at 8pm on 5* in the UK.
