Former prime minister Alberto Otarola resigned after a local TV station released an audio recording where he can be heard attempting to influence the awarding of government work contracts, which critics slammed as illegal.
Otarola has denied wrongdoing.
Boluarte confirmed the rest of her current cabinet in their roles, including economy minister Jose Arista and energy and mines minister Romulo Mucho.
