buy a cheap mandoline to slice the onions. put onions in pan with oil and butter in to oven to caramelize. easy.

I'm never getting one of those finger slicing contraptions and it's not the same because all the tops go hard and crispy... You still have to stand around watching them like a hawk to make sure they don't go black...it's way more complicated than pumpkin or tomato or minestrone or borscht...

second that

caramelising onions isn't difficult, it's just surprisingly hard work

also i bought a mandoline a couple of months ago, and take it from me: you only have to slip a little bit in order to find yourself waiting in the A&E to be patched up

it takes a lot of soup to satisfy me.

Or a ton of bread with it

faux show. french onion soup with a roast beef sandwich works, too. /chomp

once i made french onion soup for 80 people. boy, did i cut a lot of onions.
