Sweet Potato & Caramelized Onion Shells

Gorgonzola cheese and sweet potatoes add a fun and flavorful twist to classic stuffed shells. Delicious with a sprinkle of Parmesan, the pasta can be topped with leftover gravy, too. —Robin Haas, Cranston, Rhode Island

    Maybe this tastes better than it sounds. I like stuffed shells, but the weird combo of ingredients here seems a little too much like a clean-out-the-fridge experiment. Sorry, not something I would make..

    Question - "Apple cider or sherry" - VINEGAR or the real stuff?

    Certainly an unusual take on stuffed shells, but my husband and I really enjoy trying new rhings and we both loved these.

    This was a vary good dish and I definitely enjoyed the flavor combinations. The sweet potatoes provided a sweetness that mixed well with the caramelized onions and the gorgonzola provided a nice saltiness. My brother suggested adding bacon which I may try in the future. The gravy is a must as the shells tend to dry out a bit in the oven. Next time I will also add gravy to the bottom of the pan before baking. Other reviewers felt the gorgonzola taste was a bit strong so I only used 4 ounces and if anyone else prefers to use weight (like myself) 1.5 cups of sweet potatoes is about 13.5 ounces. Overall I enjoyed this dish and did not find it as time consuming as some others felt it was. I will be making this again.Kimmyjo62- Sweet potatoes are actually root vegetables, they just happen to be high in a type of carbohydrate known as starch. So what are you saying? Veggies and Pasta don't mix?

    My neighbor made these without the gravy and they were delicious. If you don't like gorgonzola though, you won't like them because that is the predominant flavor. I thought this was a very unusual, yet very tasty combo. I'll be making this myself very soon.

    I'll say up front, that I haven't made this. Who in their right mind would put these two starches together? Pasta & potatoes? I like all the ingredients, but sounds like this would be a litte all together. I could be wrong, but this does sound weird. I'll save my money and time and prepare something else.

    My family enjoyed this enough we had it as a side dish in our Thanksgiving meal.

    I thought it was delicious. Everyone at Thanksgiving dinner raved about them. But they were very time consuming to make.

    I am not sure I want to do the gravy either but I think it sounds yummy and I am thinking of making it this weekend for a pre-turkey-day turkey day!
