The 'Belgian Bullet' – winner of the 2017 China Championship with a 10-5 final win over Shaun Murphy – secured victory at the Marshall Arena with a 3-0 win over Stuart Bingham, a 2-2 draw with Ryan Day and a nail-biting 2-2 draw with Ben Woollaston, who agonisingly fell one frame short of the title.
Englishman Woollaston watched Brecel make 67 in the opening frame of the final match knowing he needed a victory, but responded superbly as runs of 141, helped by an astonishing fluke on a pink, and 126 left him on the cusp of victory.
The composed Leicester potter saw a mid-range red somehow fall to drop in the final frame of the 64-man event, enabling Brecel to sweep home a glorious 111 to take the trophy back to Belgium by topping the table on five points.
For a match between the world number 37 Brecel and world number 38 Woollaston, it was a demonstration in how strong snooker is at the elite level.
Played behind closed doors and staged under strict UK government health guidelines with players and officials tested for COVID-19 in the Marshall Arena bubble, Brecel cut a calm, cool and collected figure.
He secured the £30,000 first prize from snooker's first tournament since March and also qualifies for the Champion of Champions tournament in November.
The event was a huge success story and Brecel certainly a worthy winner.
"It was the biggest test of my career that final frame because Ben was playing so well. It is just amazing," said Brecel, who did not lose a match over nine contests at the 11-day event.
"Most of the time I'm pretty cool under pressure, but this time I was very nervous, pretty shaky. I had to stay in quarantine for three days since Sunday, but if you win the tournament it doesn't matter. I'm over the moon, I don't know what to say.
"That's what made this final more special - knowing the winner would get to the Champions of Champions. It's a massive bonus for me and I'm really looking forward to that already."
Brecel made a flying start to the day as 2015 world champion Bingham was restricted to only 12 points in three frames as the 25-year-old from Dilsen-Stokkem powered home breaks off 105 and 106 in a resounding victory.
He continued his heavy scoring streak with further runs of 85 and 57 against Day before the Welshman rescued a 2-2 draw with a fine break of 105.
Woollaston had enjoyed a 3-1 win over Day aided by a 66 knock in the third frame, but lost to Bingham by the same scoreline as the 'Ball-run' kept alive his hopes running in 74 and 71.
With Day unable to win the group, Bingham knew he had to record a victory to stay alive, but was forced to settle for a 2-2 draw in a match that was blighted by some odd errors from both men.
Day moved 2-1 clear courtesy of a 71, but Bingham nicked a point with a closing 55 knowing that his chances of the title were over.
