Sigurdarson is out of contract at Molineux this summer.
Sigurdarson has failed to score in 15 appearances since recovering from a long-term injury midway through the campaign, though he has had an impact, according to Jackett.
“We’ve had games where he’s held the ball up very well and we’ve got goals from midfield,” the 54-year-old told Wolves' website.
“I do understand that supporters want to see strikers that can score goals, and it is for us to create those chances.
“We need to put in enough decent crosses and balls from midfield, and sometimes just have enough sustained pressure or for those forwards to be able to create something out of nothing, turn a bad ball into a good one and create a good one out of nothing.
“They are the options that we’re looking at and we want our forwards to be scoring one way or another - it’s what we need.”
Sigurdarson has scored just seven times for Wolves in four injury-hit years at Molineux, during which he has made 75 appearances.
The Iceland international, who cost a reported £2.5m from Norwegian side Lillestrom, is out of contract at the end of the campaign and a renewal seems unlikely at this stage.
However, Sigurdarson is not the only Wolves striker guilty of misfiring this season, with Adam Le Fondre finding the net three times in 25 appearances and Joe Mason on target just twice since his January switch from Cardiff City.
Jackett's midfield options have been further reduced by the loan recall of Jeremy Helan by Sheffield Wednesday and one of Conor Hunte or Jed Wallace is expected to replace the Frenchman in Saturday's visit of Rotherham United.
