You will want to leave the root section on the onion as it will allow the "leftovers" to last longer in the fridge. Just for fun when my kid was little, when we got down to the root section, we put it in water to root it, then planted it. My kid loved that he "cloned" onions. He was really into gardening. We put the first "clone" into a glass jar so he could see the onion grow better.
My friend in Belgium would boil veggie "leftovers" that were not used in dishes to make a veggie broth.
