AIK came from two straight 0-1 losses away against Malmö and Halmstad.
But back at home, the Stockholm team convinced again.
The victory numbers were written to 3-0 against Östersund and AIK is thus still in the Allsvenskan gold battle.
Nicolas Stefanelli rolled in 1-0 to the home team in the 27th minute.
Left-back Erick Otieno broke into the penalty area and found the Argentine striker slanted backwards who could score the first goal of the match.
Stefanelli had a chance to extend the lead five minutes later.
The shot then came from the right wing and found Stefanelli clean in the penalty area, but the finish was far too tame.
AIK went to halftime break with a 1-0 lead.
Cannon goal by Elbouzedi
In the second half, the Irishman Zachary Elbouzedi struck.
With 62 minutes played, the visitors could have drawn level after Aly Keita came through the middle, but his kick went wide.
It was the Irishman's first goal in the Allsvenskan.
- I have had a bit of bad luck with the finishes.
But I'm so happy to get the goal and three points.
It is good to get a victory before the national team break, says Elbouzedi to Discovery +.
It also did not take long before AIK could put 3-0.
Elbouzedi found an independent Nabil Bahoui who put in 3-0 which was also the end result.
Then AIK had several opportunities to score additional goals.
Veteran Henok Goitom burned a giant position in overtime.
AIK now has three points up to Djurgården after 27 rounds played.
Malmö also plays on Sunday and can take over the league lead.
