We report the results of infrared spectroscopic observations of embedded high-mass young stellar objects in the Large Magellanic Cloud. The CH3OH ice absorption band as well as the 3.47 μm absorption band are detected toward the embedded sources in the LMC. The properties of these spectral bands in the low metallicity environment are investigated based on comparisons with Galactic embedded sources.
