The government has seven new faces including Essam al-Marzouk who was named minister of oil, electricity and water.
Marzouk, a member of a merchant family, was a board member in national oil conglomerate Kuwait Petroleum Corp. and also the head of the Kuwait Bourse Company.
Besides Prime Minister Sheikh Jaber Mubarak Al-Sabah, the cabinet includes five members of the Al-Sabah family which has ruled Kuwait for two and a half centuries, as many as in the previous cabinet.
But Sheikh Mohammad Khaled Al-Sabah, the former interior minister and a senior royal, was moved to the defense post, apparently after many opposition lawmakers vowed to grill him over the revoking of citizenships of several opposition activists.
The defense minister in the previous cabinet, Sheikh Khaled Jarrah Al-Sabah, who is also a member of the ruling family, was given the interior portfolio, AFP reported.
Foreign Minister Sheikh Sabah Khaled Al-Sabah, a royal, was also retained.
Anas al-Saleh remained the finance minister in the new cabinet despite strong criticism for his economic policies which included reducing subsidies and raising the price of petrol.
Several MPs have vowed to question him if he was retained in the cabinet.
The government of the oil-rich Persian Gulf state resigned last month as required by the constitution following the November 26 general election in which the opposition and its allies won nearly half the seats in parliament.
The 50-member legislature is scheduled to start meeting on Sunday.
The opposition has vowed to oppose the government's austerity measures in the face of low oil revenues.
The reappointment of Sheikh Jaber, 73, who has held the post since late 2011, came despite calls by a number of opposition MPs for a new premier to reflect the result of last month's polls.
The opposition groups boycotted two general elections in 2012 and 2013 in protest at a change in the voting system brought unilaterally by the government.
Under Kuwait's constitution, the emir has the sole power to appoint the premier regardless of the outcome of polls as the country does not have a full Western-style multi-party system.
The new cabinet is not required to have a vote of confidence from parliament.
