The remaining ministers will stay in their posts under plans outlined by Prime Minster Mateusz Morawiecki on Friday evening.
Morawiecki said the new government would largely be a continuation of the existing one.
In one of the changes, the finance ministry will be taken over by Tadeusz Kościński, the current deputy minister. He will replace Jerzy Kwieciński, who is leaving the government.
Foreign Minister Jacek Czaputowicz is set to keep his job. But, in a key change, a separate European affairs department, headed by Konrad Szymański, will operate as part of the Prime Minister’s Office, Morawiecki announced.
Among other planned changes, a new climate ministry will be set up, separate from the environment ministry.
The conservative Law and Justice party, allied with two smaller groupings in a United Right coalition, secured a second term in power after winning Poland's October 13 parliamentary elections.
Morawiecki said on Friday that the Family, Labour and Social Policy ministry was set to be taken over by Marlena Maląg.
The head of the enterprise and technology ministry, Jadwiga Emilewicz, is set to become development minister.
The new government line-up was earlier on Friday approved by Law and Justice’s Political Committee.
The incoming Cabinet needs to be sworn in by President Andrzej Duda and receive a vote of confidence in parliament, where the conservatives have a majority.
The new parliament will convene on November 12, a spokesman for Duda has said.
Law and Justice leader Jarosław Kaczyński said ahead of the elections that his party would bring in a raft of new policies during the first 100 days of its next term in government.
