What's the best way to slice an onion?

Online Answer
If you are slicing the onions for making caramelized onions, it's best to slice them lengthwise, or from stem to root. This way the onion holds its shape better during long cooking. To slice an onion to be used raw in a salad or a sandwich, you can halve it and then cut it crosswise, for pretty, half moon shapes.
