The Australian No.1 has stormed into the final of this week's ATP event in s-Hertogenbosch, overwhelming Frenchman Adrian Mannarino, a former winner in Holland, 6-4 6-1 on Saturday.
Awaiting him in the final is Poland's world No. 76 Kamil Majchrzak who upset the third-seeded Russian, Daniil Medvedev, 7-6 (7-4) 6-1.
De Minaur turned on the power to take the last 10 games, transforming a close-fought contest into a one-sided parade to reach his 21st career final. Winner here two years ago, another success would bring up De Minaur's 12th ATP title.
Mannarino had initially looked like making a fight of it, leading 3-0 and 4-2 in the first set before a run of unforced errors as De Minaur hit the turbo-boost button ended the match as a contest.
There must be something restorative in the Holland air for De Minaur, the second seed, Â is on course for a rare Dutch double.
He won the ATP 500 trophy in Rotterdam in February and can now emulate local hero Richard Krajicek, the only player to have won both Dutch ATP Tour titles in the same season, 1997.
De Minaur declared himself "super happy" with the victory. "It was a very tricky match against a tricky opponent and tricky conditions.
"There was not a lot of top spin being played today, so it made some interesting rallies and I'm super happy to be here in the final."
Majchrzak is just the sixth Polish man to reach a tour-level championship match in the Open era and victory against De Minaur would see him break into the top 50 for the first time.
Australia's other Dutch hope, Ana Tomljanovic, fell in her attempt to reach the women's final, bowing out 6-4 6-2 to American Robyn Montgomery.
Defeat came hours after she had completed a quarter-final victory over another American, Caty McNally, in a match suspended overnight with the Aussie leading 6-4 4-1.
She took just minutes to dispel a 0-3 head-to-head record with McNally, polishing off a 6-4 6-1 success.
That put her through to her first tour-level semifinal since Rabat 2025, and first on grass since Birmingham 2024 - but a place in the final proved beyond her.
