It's better to provide a minimal example when asking such questions.
The following works fine for me.

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{minted}
\begin{document}
\begin{minted}{java}
enum Colors {RED, GREEN, BLUE};
\end{minted}
\end{document}

%%% Local Variables:
%%% coding: utf-8
%%% mode: latex
%%% TeX-master: t
%%% TeX-command-extra-options: "-shell-escape"
%%% End:
--8<---------------cut here---------------end--------------->8---

After invoking the LaTeX command, switch to the log buffer using `C-c
C-l'.  Its first line shows the actual command being executed.  What is
it?  Here, it is

  Running `LaTeX' on `minimal-minted' with ``pdflatex \
          -file-line-error -shell-escape --synctex=1 \
          -interaction=nonstopmode "\input" minimal-minted.tex''

I guess yours doesn't include the -shell-escape option although it
should.  Did you configure the "TeX"/"LaTeX" entries in
`TeX-command-list'?  Or did you configure `LaTeX-command-style'?

BTW: Why do you have a pdflatex `TeX-engine'?  That's not predefined in
AUCTeX.  When you want to compile to PDF, you only need to enable
`TeX-PDF-mode' which is actually the default since AUCTeX 11.88.

This means that pygmentize is not in PATH.

This means that pygmentize is in PATH when pdflatex is called from your
default shell.  I guess that's BASH.  Do you have something like

  export PATH="$PATH:/path/to/pygments/bin/"

in your ~/.bashrc?  If yes, that should probably go into a file that's
sourced by any shell, not only BASH.  On many distros that's ~/.profile.

Alternatively, you could adjust the PATH in emacs using:

,----[ C-h f setenv RET ]

`----

E.g., you could add something like

  (setenv "PATH" (concat (getenv "PATH") ":/path/to/pygments/bin"))

to your ~/.emacs.

I don't use nor recommend prelude (or any other mass-configuration
package).  But if it modifies `TeX-command-list' or
`LaTeX-command-style' or something like that, this might be the culprit.

I stick to the official support channel for AUCTeX which is this very
mailinglist.  Feel free to link here from the stackexchange entry.
