Ouattara, 19, held off two defenders to strike home the ball from close range after a breakaway attack in the third minute of stoppage time at the end of the first half.
The striker, who later got himself sent off, was set on his way by a pass from inside his own half from Blati Toure as the Burkinabe played a clever counterattacking game to advance to the last four of the tournament in Cameroon.
It is the third time in the last five editions of the continental championship that Burkina Faso have got to the semifinals and they will next take on the winners of Sunday’s quarterfinal in Yaounde between Senegal and Equatorial Guinea.
