Celtic survived a spirited Aberdeen fight-back to gain their first win in five games.
Jason Denayer put Celtic into an early lead and Kris Commons made it two just after half-time virtue of a helpful deflection off Dons defender Shaleum Logan.
David Goodwillie headed Aberdeen back into the game before Craig Gordon pulled off a string of saves.
The Dons continued to attack but could not find an equaliser.
It is a welcome three points for Celtic boss Ronny Deila after the Champions League knock-out to Maribor and a failure to win on the road away to Inverness and Dundee.
Aberdeen’s second-half performance will give manager Derek McInnes some encouragement, but it is a third defeat in five games as the Dons struggle for the same consistency they had last season.
Celtic were boosted by the earlier than expected return of captain Scott Brown, who made his first appearance of the season following a hamstring injury, while Aleksandar Tonev and Stefan Scepovic also made the starting line-up.
Jonny Hayes managed to shake off an ankle knock for the visitors but was forced to pull out due to his wife going into hospital to give birth.
