Use #+call lines with the :cache header argument set.  With a recent
version of Org-mode the following should work as expected.

#+Title: An Example of Using the Cache Header Argument with Call Lines

A long running code block.
#+name: foo
#+begin_src emacs-lisp :var bar="baz"
  (sit-for 5)
  (message "bar=%S" bar)
#+end_src

#+RESULTS: foo
: bar="baz"

This returns immediately thanks to the cached result.
#+call: foo("qux") :cache yes

#+RESULTS[49bbb37e59694c557889ca8fd4b06fe0d4fb6b25]: foo("qux"):cache yes
: bar="qux"

This does not return immediately, because the block must execute.
#+call: foo("quxxx")
