know your onions: be very knowledgeable about something. If someone says you know your onions, it means you are experienced in something or you know a lot about a particular subject.

Other ways of saying it, is 
- that you really know your stuff. E.g. When it comes to making cakes, my mum really knows her stuff.

- show somebody/know/learn the ropes

(informal) to show somebody/know/learn how a particular job should be done. E.g.  Tom's very experienced-he'll show you the ropes.  It will take me a couple of weeks to learn the ropes but after that I should be fine.  Don't worry about Sara's taking over that reporter's job-she already knows the ropes.
