Recipe request: asyncio "spin off coroutine"

When you work with threads, it's pretty straight-forward to spin off
another thread: you start it. Your current thread continues, and the
other one runs in parallel.

What's the most straight-forward way to do this in asyncio? I know
this has been asked before, but threads keep devolving, and I can't
find back the one I want :| This seems like a recipe that needs to be
in the docs somewhere. Consider:

async def parallel():
    print("Doing stuff in parallel")
    await asyncio.sleep(1)
    print("Done stuff in parallel")

async def do_stuff():
    print("Doing stuff")
    asyncio.spin_off(parallel()) # ???
    print("Doing more stuff")
    await asyncio.sleep(2)
    print("Done doing stuff")

Whenever do_stuff gets called, I want it to run to completion in two
seconds, AND the parallel process should run to completion during that

What code should go on the "???" line to accomplish this?
