Ryan Dow is given a chance to score his second of the game, but he is unable to generate enough power as he prods the ball into the arms of goalkeeper Kyle Letheren from 16 yards.
Dundee have a chance of a quick reply when a cross falls to Gary Harkins at the back post, but a superb block by Keith Watson from the midfielder's drive means the home side have to be satisfied with a corner.
Dundee United surely put the game beyond Dundee as they score a quick-fire third goal.
Paul Paton's free-kick to the near post finds Callum Morris with space and the defender who joined from Dunfermline Athletic in the summer powers his header into the net from eight yards.
Ryan Dow is booked for going behind the goal to celebrate his goal with the Dundee United fans.
It is Jim McAlister's turn to be punished for losing possession. John Rankin's tackle sends Ryan Dow racing towards the Dundee goal and he switches the ball to his left before driving low into the corner of the net from 16 yards.
Greg Stewart bursts into the United penalty box, but Sean Dillon cuts across the striker to end the danger and goalkeeper Radoslaw Cierzniak sweeps it clear for a corner. Stewart is penalised for barging Dillon, so Dundee don't even get the compensation of a corner kick.
Dundee United kick off the second half. They deserved to open the scoring, despite the controversial nature of the penalty award, but Dundee ended the first half on top.
Former Dundee goalkeeper Rab Douglas tells BBC Radio Scotland that he reckons there was minimal contact on Gary Mackay-Steven but that referee Steven McLean made the correct decision in awarding a penalty.
Pundit Craig Paterson on BBC Radio Scotland
"It has been stuffy. Dundee have not troubled the goalkeeper much and United have been better in that respect."
Paul Paton is the next United man to go into the referee's book for a foul on Philip Roberts.
Jim McAlister heads on to the roof of the net from 14 yards from the resulting free-kick.
Dundee United midfielder Chris Erskine goes into the referee's book for a clumsy challenge on Paul McGinn.
Dundee's share of the ground rises in expectation as Philip Roberts sends a side-foot effort into the side-netting.
From some angles, that would have looked like it rippled the other side of the net.
The former Arsenal midfielder was picked out by a sublime Gary Harkins chip, but the volley was not accurate enough.
JungleLion: Aberdeen can't wear red when they play Dun Utd now.....so why is the ref allowed?
Good question Jungle Lion...
Dundee supporters fire some ironic cheers in the direction of Gary Mackay-Steven as the winger slips and falls to the deck.
Was his earlier collapse in the penalty area deserving of a spot kick, or a booking for diving? Give us your thoughts. Text on 80295 or Tweet @BBCSportScot.
Dundee have a chance to draw level immediately, but Gary Harkins' curling free-kick is comfortably held by goalkeeper Radoslaw Cierzniak.
Former Scotland defender Willie Miller on BBC Radio Scotland
"There might have been a bit of contact, but there has to be more than that. It didn't see any intent or enough to take Mackay-Steven's legs away from him. But the referee was well up with the play."
