The Tory MP sparked a furious outcry last week after he added the top role at the London publication to a string of high-paying jobs he has already signed up to since being sacked by Theresa May.
Labour this afternoon secured an urgent question over Mr Osborne's appointment, amid bemusement at how he can combine the demanding job with his role as MP for Tatton in Cheshire.
Since being told to leave government by the Prime Minister, Mr Osborne has also taken on a £650,000 per year job with a leading investment fund, been handed a role with the US-based with the McCain Institute, signed up to a lucrative speaking agency and assumed the chairmanship of the Northern Powerhouse Partnership.
Appearing in the House of Commons, Mr Osborne revealed he would "listen to what my colleagues have to say" as MPs debated his Evening Standard job, which he is due to start in May.
But the ex-Cabinet minister also made light of the row, joking how the proceedings had "missed the deadline" for his newspaper.
Mr Osborne told MPs: "When I heard that this urgent question had been granted I thought it was important to be here, although unfortunately we have missed the deadline for the Evening Standard.
"In my view this Parliament is enhanced when we have people of different experience take part in our robust debate and when people who have held senior ministerial office continue to contribute to the decisions we have to make.
"But I will listen to what my colleagues have to say in this debate, I'm interested to hear."
George Osborne has sparked fury by taking on the editor role at the Evening Standard
Unfortunately we have missed the deadline for the Evening Standard.
Labour's Andrew Gwynne described Mr Osborne's appointment as a "matter for great concern" that "does a disservice" to other MPs.
He claimed holding "several" jobs outside Parliament was "impossible to defend".
The SNP's Roger Mullin described the row as a "disgraceful shambles".
But a string of Tory MPs spoke in support of Mr Osborne over the criticism of his new job.
