slicing onions

[diego]

Is there any device, or trick, for getting whole circle slices from a big onion? My knife always walks off to the side to make either a wedge slice or a too thick side.

You can use a mandoline.

What sort of knife are you using? Serrated knives will wander 100% of the time. Short narrow-bladed utility knives do the same. I use a 10" chef's knife and get nice even slices.

if you are cutting a lot of big onions, you could do them on the meat slicer. stack a couple of them and don't use the auto feed.

Thanks everyone. The mandoline worked so well that I didn't get to trying the chefs knife. But I had been using a narrow utility knife and I am sure that the wide chefs knife would give me much less trouble.
