Excellent recipe for Thanksgiving!

Great recipe! Since I am trying to reduce the sugar in our diet, I doubled the vanilla and reduced the brown sugar to 1/2 cup. It was amazing and everyone loved it!!!!

we used "fluff" which is not made with gelatin. Just as good!

A New Standard for Sweet Potato Casserole

This recipe is a perfect balance of sweetness - a new standard for sweet potato casserole.  I roasted my potatoes and omitted pecans to accommodate my diners.  A sprinkling of mini-marshmallows was all the topping we needed.

I'm typically not a sweet potato casserole fan, but this was amazing! Made this for Thanksgiving and all of our guests loved it. Personally, I really liked the texture the pecans added against the creamy sweet potatoes. I use vanilla bean paste in place of extract and that definitely added a rich flavor. Can't wait to make this again for a side dish on a chilly winter night.

I made this last Thanksgiving. Reviewing it now because i'm cleaning up my file. I remember this being relatively easy except for trying to figure out how many potatoes to use. Our celebration was small. I think it came out super sweet which is fine for me. Maybe cut down on the sugar next time. I'm tempted to make it with Splenda. That would allow me to probably justify eating too much. I will make it again.

Marshmallows are made from animal product.... so if you add them to your dish... it is NO longer vegetarian.

This is an awesome recipe, and it is going to be added to my Holiday menu from now on! I did make a couple of changes...I added about a handful more pecans to the mixture because my famiy loves pecans, and a whole teaspoon of vanilla. I also sprinkled a layer of brown sugar on the top of the casserole before adding the pecans and then the marshmellows on top. Everyone loved it! Also I made it the night before, put it in the oven for about 15 minutes to knock off the chill, added the marshmellows and baked. You will not regret making this recipe instead of candied yams, I promise.

Prepared this exactly to recipe. This is so delicious, it's the only dish I had thirds of-- and I adore my grandma's stuffing! It tastes like maple syrup heaven with marshmallow clouds of happiness.

I thought this was good, but the rest of the family felt it was too sweet. It tastes a lot like candied yams you make during the holidays, except, as my husband put it, candied yams are primarily only sweet on the outside. Mashing the sweet potatoes makes this sweet throughout.

This is the best sweet potato casserole I've ever had. We had it as part of our Thanksgiving dinner. Everyone loved it. The kids especially liked the marshmallow topping. We mixed it up the day before and stored it in the refrigerator. We took it out of the refrigerator about two hours before putting pouring it into a baking dish, adding the remaining pecans and topping with marshmallows. I was afraid the texture was too thick and it would be dry, but it was perfect. No one would ever guess that it is a "light" recipe.
