Enroute ZZZ - ZZZ1; upon reaching cruising altitude and starting to accelerate; I noticed a burning smell that was faint at first; but persistent and grew stronger. I asked the First Officer (FO) if he smelled it too; which he replied affirmatively. We then spoke with the Flight Attendant (FA) who also smelled the burning odor in the cabin. We immediately diverted to ZZZ2 with an expedited descent; all while running the QRH and normal checklists. After turning off the recirculation fan and gasper; the smell dissipated within 30 seconds. We landed without further incident and no passengers were injured.
EMB-145 Captain reported a fumes event during cruise. Flight crew diverted to a suitable alternate for a safe landing.
