The away team took the lead through a fine finish by Leif Davis. Ten minutes later, Bruno Fernandes scored his first goal of the match to make it 1-1.
After an own goal made it 2-1, it was Fernandes' turn again when he converted a penalty after the hour mark, before completing his hat-trick a few minutes later when he made it 4-1.
In the 82nd minute it became 5-1 when Brian Mbeumo scored his first goal of the season after a fine pass from none other than Bruno Fernandes.
In injury time, Ipswich reduced the deficit to 2-5 after a defensive mistake by Lisandro Martinez.
The victory is Manchester United's first of the season after the debacle away against newcomer Hull in the Premier League opener (0-2).
