A penalty from Zlatan Ibrahimovic and Urby Emanuelson's stunning solo effort secured a win for the rossoneri that never looked in doubt and heaped the pressure on Juve in the late game.
But helped by Alessio Cerci's first half dismissal, they cantered to victory with goals from Mirko Vucinic, Arturo Vidal, Claudio Marchisio, Andrea Pirlo and Simone Padoin.
It was a crucial success for Juve and only their second win in eight games but with 10 games left, Milan appear to have hit their stride at just the right time.
Their result was earned despite a host of important first team players such as Kevin-Prince Boateng, Mark van Bommel, Robinho, Alexandre Pato, Philippe Mexes and Alessandro Nesta being ruled out.
It meant Emanuelson playing in the 'trequartista hole' behind the front two.
"(Coach) Allegri plays me as a trequartista and asked me to move up front a lot with Ibra and (Stephan) El Shaarawy and I'm happy with this role," he said.
Ibrahimovic headed a chipped ball into the box back to Emanuelson whose goalwards shot hit Cristian Zaccardo's arm and the referee pointed to the spot.
Ibrahimovic sent Antonio Mirante the wrong way and the visitors had a 17th-minute lead.
It could have been worse for Parma as Mirante failed to hold Ibrahimovic's stinging free-kick but Emanuelson volleyed the bouncing ball high over the bar.
Parma did have their moments and a Gabriel Palletta header deflected off Thiago Silva before hitting the bar with Christian Abbiati well beaten.
Ibrahimovic should have had a second when a ricochet sent him clean through but he took a heavy touch allowing Mirante to charge out and clear the danger.
Milan doubled their lead on 55 minutes when Emanuelson beat two players and then ran through before rounding Mirante and slotting home.
But the goal also owed a lot to Ibrahimovic's vision in stepping over the ball as it came towards him with Emanuelson on the charge because he was in an offside position.
Such was Milan's comfort that coach Massimiliano Allegri even afforded Gennaro Gattuso a return to first team action for the first time since early September due to an eye problem.
But deep into injury time Sergio Floccari beat Abbiati with a shuddering effort only to see the ball rebound off the bar.
Juve had previously been struggling for goals and midfielder Pirlo said it might have been better to spread them around more.
"Today it was important to stay on Milan's heels and win," said former Milan star Pirlo.
"We've scored many goals but it would have been important to score a few less here and some in other situations.
"The extra man helped but we were already in front before Cerci's sending off and hence we'd started well from the off."
Juve gave an early sign of their intent when Vucinic took a quick shot that came back off the post and with the goal at his mercy Alessandro Matri could not sort out his feet and blazed over.
But on the quarter hour mark Vucinic curled home from outside the box.
Cerci then earned a straight red card for a kick at Paolo De Ceglie.
Vucinic then teed up Vidal to shoot home at the second attempt after goalkeeper Artur Boruc saved his first shot.
After the break Fiorentina went into total meltdown.
Marchisio arrived at the back post to head home Vucinic's cross and then the Montenegro forward also set up Pirlo to clip home over Boruc.
Pirlo then had a shot deflected leaving substitute Padoin with an easy tap-in from a couple of yards out.
