Having started his challenge with a second round win over Jeffrey de Zwaan on Saturday evening, Van Gerwen averaged 107.60 in a dominant 6-1 defeat of Kyle Anderson in Sunday's third round.
He then edged out World Matchplay semi-finalist Daryl Gurney 6-5 in the quarter-finals, with the game's opening 10 legs all going with throw before the Dutchman produced the decisive break in the 11th leg by finishing 76 for a 12-darter with the Northern Irish ace waiting on 40.
Van Gerwen then came from two legs down to win 6-2 against Michael Smith in the semi-finals, with the former World Youth champion opening with legs of 11 and 14 darts but paying for missed doubles in leg three.
He then finished 80 and produced a 13-darter to lead 2-0 in the final against Beaton, who replied by taking out 52 for a 14-darter in leg three only to see the Dutchman pull clear.
A 70 finish restored Van Gerwen's cushion, a 12-darter broke and double one moved him 5-1 up before he landed a third 180 of the final and took out 77 to seal his 11th PDC title of the season.
Van Gerwen, who is and at the end of the year, told www.pdc.tv: "I think this has been a fantastic tournament. I played okay - I didn't play my absolute best but I feel good. I had a fantastic holiday and the month off with my wife and child. It's been a fantastic time and to kick off after my holiday straight away with a win is a dream.
"You know when you play Steve you have to do the right things at the right moments, make sure you are on him straight away and keep him under pressure and that's exactly what I did."
Beaton had won through the UK Qualifier just to secure a spot in Maastricht but showed some superb form - including beating UK Open champion Peter Wright in the semi-finals - as he searched for a first European Tour victory since 2013.
The 53-year-old said: "I got better and better as the tournament went on but this man just turns it on. It's frustrating because you think you've got a chance and he just takes it away from you. That's why he is number one ... fair play to him."
