Instructions Checklist
  • Preheat oven to 375 degrees. Place sweet potatoes in a large saucepan, and cover with cold water by 1 inch; salt generously. Bring to a boil; reduce to a simmer, and cook until easily pierced with the tip of a paring knife, 15 to 20 minutes. Drain, and return to pan. Heat over medium, stirring, until liquid has evaporated and a thin film covers bottom of pan, about 2 minutes.

Used evaporated milk and added a hint of cinnamon. Omitted the pepper and just added salt while boiling. Delish!

I added 1 cup of dark brown sugar on top of the yams before covering with marshmallows. Came out great except I would not use salt or pepper at all next time and use unsalted butter. The end result was to salty tasting with a hint of pepper. It was good but not what I was aiming for.

Just made this for Thanksgiving. PERFECT recipe! my family ate more of this casserole than they did mashed potatoes - AND THAT NEVER happens! I used fresh ground nutmeg. Also I threw a little sprinkle of brown sugar on top - but it didnt need it.

I just made this recipe for Christmas dinner & received rave reviews! I did sprinkle a little brown sugar on top, before I added the marshmallows. The roasted marshmallows give the casserole such a nice crunch & texture - delicious!! I will definitely be making this again! Thank Martha!

Yum!! I swapped out the nutmeg for cinnamon and added 1/3 cup of brown sugar. Also, like some people mentioned, 8 potatoes might be an awful lot for three pounds!!! In any case, the casserole was delish! Thank you Martha!

My family enjoyed this recipe on Thanksgiving. I usually make a much sweeter recipe with nuts etc., but this was extremely simple and surprisingly good!

I've been making this recipe for years, however, on occasion, I add 1/3 cup chopped walnuts. I always add 1/4 cup brown sugar as well. They have been my sons favourite since he was 3 years old and he still asks for my sweet potatoes at every family dinner and he's 40. They really are amazing.

My mom's secret has always been to add a dash of cooking sherry and very finely diced apples to her potatoes. They are to die for and every time I make them, people are trying to dissect the wonderful flavor and taste sensation.

I also used the large chopped marshmallows - I do not know how they look so dusted and white and puffy in the picture; mine kept their round shape and turned brown and glossy. It all still tasted great! (although there were so many potatoes there was not a great marshmallow-to-sweet potato ratio) Yummy, plenty of leftovers. :)

I picked out 8 sweet potatoes that came to nearly exactly 3 pounds. They did not all fit in a "large saucepan", I had to move the whole mess to a large pot. They also did not fit in a 2-quart baking dish; they were bursting out of my 2.5 liter dish. So, I would recommend fewer sweet potatoes. Probably 6. I mashed some brown sugar into mine as well.
