Does anyone have any tips for roasting sweet potatoes? Since - seems to me - they cook and break down much faster than normal potatoes I skipped the parboiling stage and just stuck them (peeled) in the oven to roast for 45-60 minutes.

However they still came out a somewhat soft and squidgy result. Roast for shorter time or some other methodology?

I suppose I am looking for a crisp texture something like a normal roast potato but keeping the orange colour and distinctive sweet taste of the sweet potato itself.
