Don't fry them in butter, get some garlic granules and put a shit load of olive oil in a pan, throw in the garlic for only a few seconds until it starts to brown, then fish the garlic out (as it will go sticky and brown quite quick), then your oil will taste of roasted garlic.
Bung in the potatoes and some fresh herbs when they're nearly done.
What he said ash, butter will just go greasy
Dead right they won't be nice. You could always lightly fry the potatoes instead of roasting them and can chuck in a bit of butter at the end - when it foams up swirls the spuds in them and they'll taste great. Tend to do this with new potatoes though
