My new favorite/go to holiday sweet potato recipe. So yummy! It’s a crowd pleaser. It does take a little effort to slice sweet potatoes but a mandolin with cut resistant gloves makes it go fast. I took off 1 star because in the picture it looks like it will get crunchy but it doesn’t. Instead the edges get caramelized giving the dish a sweet/savory flavor.
Made this for Christmas dinner. A few notes: I bought 6 sweet potatoes. When I got home I weighed them and didn't have nearly enough (I had more like 2.5 pounds). This turned out to be wayyyy too much. I sliced them on the mandoline and did have to use a fork to avoid slicing my fingers off, but I like the suggestion for cut-resistant gloves. In assembling the dish it seemed to me that it would be dry so I just poured the leftover liquid (there wasn't much) on top. The end result was probably a bit soggier than I would have hoped, but the dish was delicious and I'd make again, which is saying a lot because it was a lot of work. It was a hit at Xmas dinner but might be a better fit for a dinner without so many rich dishes. I might make it with a roast or a nice piece of meat so it has less competition.
Really, use a fork with your mandoline... dented blade, dull, and eventually unusable. Instead buy a very inexpensive cut resistant glove. I bought a three pack, (Amazon), for about $12. They have lasted two years so far, and I can run my hand across the blade without worrying about a cut. I do not have to ruin my mandoline with a fork! I am surprised at your suggestion.
