  We present 5-35 $\mu$m spectra, taken with the Infrared Spectrograph (IRS) on
the Spitzer Space Telescope, of five FU Orionis objects: FU Ori, V1515 Cyg,
V1057 Cyg, BBW 76, and V346 Nor. All but V346 Nor reveal amorphous silicate
grains in emission at 10 $\mu$m and 20 $\mu$m, and show water-vapor absorption
bands at 5.8 and 6.8 $\mu$m and SiO or possibly methane absorption at 8 $\mu$m.
These absorption features closely match these bands in model stellar
photospheres -- signs of the gaseous photospheres of the inner regions of these
objects' accretion disks. The continuum emission at 5-8 $\mu$m is also
consistent with such disks, and, for FU Orionis and BBW 76, longer-wavelength
emission may be fit by a model which includes moderate disk flaring. V1057 Cyg
and V1515 Cyg have much more emission at longer wavelengths than the others,
perhaps evidence of substantial remnant of their natal, infalling envelopes.
