	abstract = {The bright emission from high-redshift quasars completely conceals their 
host galaxies in the rest-frame UV/optical, with detection of the hosts
in these wavelengths eluding even the Hubble Space Telescope (HST) using
detailed point spread function (PSF) modelling techniques. In this study
we produce mock images of a sample of z{\textasciitilde}7 quasars extracted from the
BlueTides simulation, and apply Markov Chain Monte Carlo-based PSF
modelling to determine the detectability of their host galaxies with the
James Webb Space Telescope (JWST). While no statistically significant
detections are made with HST, we find that at the same wavelengths and
exposure times JWST NIRCam imaging will detect {\textasciitilde}50\% of quasar host
galaxies. We investigate various observational strategies, and find that
NIRCam wide-band imaging in the long-wavelength filters results in the
highest fraction of successful quasar host detections, detecting {\textgreater}80\%
of the hosts of bright quasars in exposure times of 5 ks. Exposure times
of {\textasciitilde}5 ks are required to detect the majority of host galaxies in the
NIRCam wide-band filters, however even 10 ks exposures with MIRI result
in {\textless}30\% successful host detections. We find no significant trends
between galaxy properties and their detectability. The PSF modelling
underestimates the Sersic magnitudes of the host galaxies due to
residual flux from the quasar contaminating the central core, which also
results in a slight underestimation of the Sersic radii and significant
overestimation of the Sersic indices n. Care should be made when
interpreting the host properties measured using PSF modelling.},
