The 29-year-old is currently on a season-long loan from Aston Villa, but has only managed four goals in his 18 appearances in all competitions so far.
Bent did find the net in the 1-1 FA Cup draw with Norwich City, and Meulensteen believes that the former England man can still have a big impact on the Cottagers' season.
"Darren's going to be important for us," he told the Daily Mirror. "Sometimes players get knocked out of their stride.
"It's how they respond and if they do it in the right way they come back stronger.
"His stats don't lie. He's still a very good striker that you want to have in your squad. Every forward thrives on that confidence to get that goal.
"He might be one of those players who gets in a rhythm where he can't stop scoring."
