The Hoops extended their unbeaten run to 22 games, while making it 11 straight victories in the league as they continue to brush aside all comers.
"I'm very pleased. The football we played in 1st half was exhilarating," Lennon told reporters after the game. "I thought Brown and Ledley were outstanding in midfield so it was a really good all-round team performance. I couldn't be happier with them.
"A lot our good football came through James [Forrest]. It's no coincidence that he's come back into the team and we are scoring goals at a very high rate at the minute."
Celtic will be looking to extend their unbeaten run further when they face St Mirren next weekend.
