The MP Motorsport driver scored 265 points in 2022, taking five wins and 11 podiums on his way to the title.
Theo Pourchaire was second on 164 points, with third-placed Liam Lawson on 149.
Speaking at the FIA Prize Giving in Bologna, Drugovich said it had been an “amazing season” which had “opened a lot of doors.”
Days after winning the title in Monza, Drugovich was announced as Aston Martin Formula 1 Team’s reserve driver for 2023 and the first member of its Driver Development Programme.
Drugovich said: “It’s been an amazing season, it’s hard to describe with words. I think we managed to put it all together.
“The main goal for me was just to win it, but also to do that I wanted to be really consistent and I managed to do that so I’m really happy with the results.
“It’s opened a lot of doors for me in the future.”
Asked whether he was surprised by the level of dominance with which he won the title, Drugovich added: “Yeah, I think I was.
“At the beginning of the season, I was quite good, then in the mid-season we had a little bit of a fall and we lost a bit of points compared to our competitors.
“Then we managed to gain a lot more back at the end so I’m really happy with that and yeah, I was quite surprised with the performance.”
Drugovich helped MP to score their first F2 titles, with the Dutch outfit also securing the teams’ championship with the help of team-mate Clement Novalak.
The Brazilian had driven for the team in his rookie F2 season in 2020, finishing ninth, before moving to UNI-Virtuosi for 2021.
But after a disappointing year, where he finished eighth, Drugovich returned to MP for 2022 and helped them to their biggest achievement to date.
He said: “I think after my second year in F2 I wasn’t really supposed to do a third year, and I got a call from the team late-December or something like that, which is normally when everything is done.
“They asked me if I wanted to join and I really thought about it because MP hasn’t won anything before this year, so I was like ‘okay, maybe we have to see.’
“But at the end I said yes because they helped me a lot also in every way, also financially which was the main issue, and I managed to get the job done.
“So I think it was the best decision I’ve ever made.”
