All eyes were on the mercurial Italy striker following his £19million arrival from Manchester City and he duly delivered a clinical brace, his first goal arriving in the 24th minute.
Gianpiero Pinzi pulled Udinese level in the second half and as Milan drifted towards a draw, Balotelli's head appeared to drop.
But he snatched up the ball with glee when Stephan El Shaarawy won a suspicious penalty from Thomas Heurtaux in the final minute of injury time.
Despite Udinese's angry protestations - Heurtaux appeared to make a clean tackle - Balotelli kept his head from the spot to fire his new employers into fourth place in Serie A.
