Hazem al-Beblawi is the new PM, under the interim President Adly Mansour.
The swearing in followed another night of violence between security forces and Morsi supporters that left seven dead.
A spokesman for Morsi's Muslim Brotherhood called the interim government "illegitimate".
Morsi was ousted on 3 July in what many have said was a military coup.
The army said it was fulfilling the demands of the people after mass anti-Morsi protests.
