An out of the way sort of route (5)

I believe the answer is:

outre

I'm a little stuck... Click here to teach me more about this clue!

'an out of the way sort' is the definition.
I can't judge whether this definition defines the answer.

'of route' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'route' anagrammed gives 'OUTRE'.

Can you help me to learn more?

(Other definitions for outre that I've seen before include "Conspicuously unconventional" , "Extravagant; bizarre" , "Peculiar" , "off the beaten track" , "kinky?" .)

I've seen this clue in The Globe and Mail.
