Fast caramelized taste for soup I want to make soup, a random soup. 
suppose that I want to to give it a deep taste, like a caramelized onion taste.

because I only need the taste, I don't care about texture.
can I get the equivalent of caramelized onion fast? like, 15 minute fast?

I read somewhere that I can brown onion fast if I fry it first without oil,salt or anything, destroying interior speed up the process of carammelizing and browning.

or is giving the soup a storebought caramel bar able to give equivalent deep taste? 
or caramelized carrots, garlics? 
I only need the caramelized taste, because the main flavour will be from spice and herbs.
the question is this:
what are the fast ways (under 16minutes) to give a soup a deep,caramelized taste?
You can add a little bit of sugar to your onions while cooking them; this will help them get caramelized faster. (or at least get some caramel flavors).

But you will need to check them often in order not to burn the sugar too much.
