Using that snippet, I'm still seeing a window pop up containing the
contents of /etc/shadow when I run:

emacs -Q -l start-up.el
M-x sudo-test RET
<password> RET

where start-up.el contains the following code:

(add-to-list 'display-buffer-alist '("\\*Async Shell Command\\*"
                                     display-buffer-no-window (nil)))

(defun sudo-shell-command (command)
  (interactive "MShell command (root): ")
  (with-temp-buffer
    (cd "/sudo::/")
    (async-shell-command command)))

(defun sudo-test ()
  (interactive)
  (sudo-shell-command "cat /etc/shadow"))
