Roast potato and cauliflower topping for pasta is a great dish for cold nights. If you substitute sauteed breadcrumbs for Parmesan cheese this meal is vegan.
I made it with spaghetti. A pleasant change from the multitude of cauliflower soup recipes and curry recipes (I am a bit if an Indian cuisine specialist, so I don't need to be told how to make curries). - 04 Jul 2015
I have to admit, I never made this recipe with the pasta, as instructed. Instead, I made the potato/cauliflower portion as a vegetable side dish for my last dinner party. I honestly cannot say how good it is with penne, but I can say that the potato/cauliflower portion was an excellent side dish! Everyone at the party raved about it, and it also made yummy leftovers. - 10 Jan 2007 (Review from Allrecipes USA and Canada)
This was really good. I would probably not use quite so much olive oil next time -- just a taaad less. I only made the cauliflower and potato portion of this, and didn't have onion or rosemary, so it was modified slightly out of necessity. But I would definitely recommend. - 30 May 2009 (Review from Allrecipes USA and Canada)
