This was surprisingly good! I was cooking for two only so reduced the pasta; the pasta to other-stuff ratio was perfect. Had I cooked the full amount of pasta I think there wouldn't have been enough sweet potato and I probably wouldn't have liked it as much.
I didn't have any ricotta so just sprinkled on some grated parmesan and chunks of mozzarella - super! Had to up the pepper though, since it has such straight-forward flavors going on.
This dish has a beautiful combination of flavours: the sweetness of the potatoes and the pine-aroma of the rosemary work well together. I made this extra-creamy by mixing in the ricotta with the noodles, simulating the effect of a cream sauce, rather than laying the daubs on top as shown in the photo. An easy and tasty vegetarian main.
This dish was wonderful! I have made it several times since seeing it as part of the month of dinners. The recipe says sweet potatoes, but the picture is of yams. I bought the sweet potatoes then saw the picture so went back and got yams too. It was really nice. Best to dice even smaller than 1/2 inch cubes though. This recipe is a keeper!
