Ajax, who finished the season two points above PSV Eindhoven, will bring the title back to Amsterdam for the first time since 2014.
The Dutch giants have now won the domestic double after they beat Willem II in the KNVB Cup earlier this month.
Ten Hag's side only needed a point from the clash against De Graafschap to see them crowned as champions.
But they secured the title in style after Lasse Schone and Nicolas Tagliafico scored before Dusan Tadic bagged a brace.
After the final whistle, Ajax fans went wild in the away end of the De Vijverberg.
Masked fans let off flares and climbed all over the barriers while they watched their players lift the trophy.
The celebrations continued on the streets of Amsterdam – where fans also used flares to fill the surrounding area with bright red smoke.

It could have come sooner for them, but the Eredivisie postponed an entire round of fixtures to give Ajax more time to prepare for their match against Spurs.
Ajax won the first leg 1-0, but Tottenham pulled off an incredible comeback in the next match to send them through on away goals.
