A major conundrum of particle physics is what mass ordering (MO) follow neutrinos. The construction of next-generation neutrino detectors of unprecedented size, sensitivity and budget is underway and an answer is expected in the next decade through the combined study of reactor, atmospheric and accelerator neutrinos. In this Letter, the potential of an additional pathway is pointed out. Due to the MSW effect the flavor content of the neutrino flux from a Core-Collapse Supernovae (CCSNe) is highly dependent on the true neutrino MO. To exploit this feature, an analysis strategy robust to systematic uncertainties is identified for the first time and, by means of it, is shown that for a paradigmatic galactic CCSN a MO separation similar to 5~$\sigma$ can be achieved.
