Flanker Tyler Ardron and prop Duncan Jones crossed for tries as the Ospreys are made to battle all the way for this win over Zebre.
Fly-half Matthew Morgan scored 20 points to put the Ospreys top of the Pro12 for at least a couple of hours.
The Welsh side have to wait and see how Munster fare against the Cardiff Blues later this evening to see if they stay top.
Flanker Filippo Cristiano and number eight Samuela Vunisa scored for Zebre.
The Ospreys, having lost six of their last seven matches in all competitions, were forced to come from behind in the first half at the Liberty Stadium.
The Welsh had second-half tries from Canadian flanker Aldron and veteran prop Jones - his first score for four years - to thank for this win.
Zebre, who had beaten the Blues 30-25 and drawn with the Scarlets already this season, made the home side fight all the way for the points.
The Ospreys had been boosted by the return of wing Hanno Dirksen, making his first Pro12 start since undergoing knee surgery in November 2012.
Zebre scored the only try of the first half through flanker Cristiano but still trailed 15-13 at the interval to five Morgan penalties.
After half-time the Ospreys went a long way to sealing their win with two tries in four minutes.
The first was a well-worked move started by some good link work between full-back Richard Fussell and Dirksen before scrum-half Tito Tebaldi's long pass put Aldron over.
Jones' try - only his fourth in 196 Ospreys appearances - after some good build-up work by centre Ben John.
Zebre responded with a try for Vunisa, but his sin-binning for a professional foul on the 69th minute ended any hopes the Italian side may have had of a comeback.
