Recurring changing-look active galactic nuclei (CL-AGNs) are previously identified sources that have brightened again and reverted to their earlier spectral state, or vice versa, offering new constraints on the mechanisms driving these transitions. We present spectroscopic follow-up observations of nine CL-AGNs selected from Dark Energy Spectroscopic Instrument, whose recent optical fluxes from the Zwicky Transient Facility show trends consistent with their historical bright or faint states observed in the Sloan Digital Sky Survey. Using new optical spectra obtained with the 200 inch Hale Telescope and Gemini North Telescope, we find that three of the objects exhibit clear evidence for recurring changing-look behavior. Four others display stochastic variability without signs of a repeat transition, while two cases remain inconclusive due to limited spectral coverage. Importantly, we demonstrate that once the photometric flux returns to the same level as in the prior bright or faint state, timely spectroscopic follow-up can effectively confirm the recurrence of a CL transition, thereby constraining the real timescale of the phenomenon. The three confirmed recurring CL-AGNs constrain the timescale of repeat transitions to less than three years in recent events, favoring scenarios such as episodic accretion driven by disk instabilities or rapid inflow variations. More rapidly recurring CL-AGNs also provide a valuable opportunity to probe the physical structure and evolution of the broad-line region.
