I dunno about 10 minutes, but in my very limited experience it's easier to crank the heat up when you have several pounds of onions. Otherwise, if you're just carmelizing one onion, stirring doesn't really allow you to temporarily remove the onion from the heat, whereas if you have a large amount of onions you're basically turning over the whole lot.
I've only made French onion soup once or twice, but I make Italian sausage, peppers, and onions regularly. I'm not shy about cranking the heat up, but with just 1 onion and 2 bell peppers some of the onions invariably end up a little burnt even before they've begun to carmelize; but in that dish that's not necessarily a bad thing.
I use the microwave to make a dark Cajun gumbo roux. I'm curious if the microwave would work well for carmelizing a small amount of onion. Though, using the microwave for a roux isn't much faster than using a pan; it's just more difficult to fsck-up.
If you crank up the heat you're not caramelizing, you're browning (burning). Caramelizing is a chemical process which requires lower heat and longer time.
I think you can make it happen with a small amount of onions, but you have to watch it like a hawk, stir constantly, and add a small amount of water whenever it starts to go too far.
