The Red Devils were always in pole position having won the quarter-final first leg at Stamford Bridge 1-0 – and took complete control of the tie on 43 minutes when Javier Hernandez smashed home from close range following a fine cross from veteran Ryan Giggs.
Chelsea had started with Fernando Torres up front, but he was hauled off at half-time and replaced by Didier Drogba.
The visitors had Ramires, John Terry and Florent Malouda on yellow cards in the second half, and Ramires was sent for an early bath after clumsily fouling Nani to see yellow for a second time.
Drogba brought the tie to life on 77 minutes, though, when he latched onto a cracking Michael Essien pass and slotted past Edwin van der Sar.
United were ahead again in the same minute, however, as Giggs’ sublime lofted pass found Ji-Sung Park, who controlled and despatched a clinical left-footed strike into the net.
Sir Alex Ferguson’s troops now face Schalke or Inter Milan in the last four on April 11.
