I have always stayed away from sweet potatoes with marshmellos on them. I decided to give it a try because the corn flakes seemed intriging. It was wonderful. The corn flakes added a kind of nutty crunch. My guest all went home with this recipe.

I have always used honey almond granola in place of the Cornflakes. So much better!!

Best Sweet Potato Casserole!!

I've made this a couple of times and it was so delicious! I barely had any left over. I DID cut the sugar in half the second time, it was way too sweet as called for. Made with a mixture of half white, half brown sugar.  I don't know how anyone can call this recipe bland - it's incredibly good, and I typically hate sweet potato recipes with marshmallows. I think I liked it because it was a LESS syrupy, out of a can kind of recipe. Making again tonight, just because!

I have made this casserole for many years so of course it has become  staple on my holiday dinner table.  I have made a few adjustments which might be helpful to some of you.  I add a half teaspoon of finely zested orange peel while mixing the sweet potatoes with the other ingredients.  Also, if you watch the video, you can see how easily the skins slip off the sweet potatoes after they are baked.  There is no peeling involved. A big plus for me with these toppings is that some people do not like marshmallows and some do not like a crunchy topping.  Thus, this topping  gives everyone a choice.

I'm not sure what I did wrong.

Not a bad recipe, but the cornflake side of the topping came out soggy. I didn't make the topping ahead of time, I mixed it with the exact amount of butter and pecans right before I put it on the casserole, so I do not think I oversaturated it, so I'm not sure how to fix this problem.

Classic Sweet Potato Casserole

November 30, 2015
I made this today for Thanksgiving.  IT WAS THE BOMB!  I made a few minor adjustments to the recipe.  I added cinnamon to the potato mixture, doubled the vanilla and brown sugar, tripled the pecans, and substituted Raisin Bran flakes for the corn flakes.  For the final step, I put the marshmallows on first (evenly), sprinkled the pecans mixed with butter and brown sugar next, then topped it with the crushed bran flakes.  The topped was super crispy and the potato blend was soft and gooey.  We added vanilla ice cream on top and it DISAPPEARED even after the turkey dinner was consumed.  Best sweet potato recipe I have ever made.

Sweet potatoes should be used year round more!

Looks wonderful! Have not made yet but had to rate in order to ask these questions. Questions: The video shows 1 and 1/2 cups softened butter added to sweet potato mixture; the recipe calls for 1/2 cup softened butter to be added. Please, can someone clarify? Also, do you measure the corn flakes before or after crushing? Thanks!

I like my sweet potatoes straight with a little butter, salt and pepper but was asked to bring sweet potato casserole to Thanksgiving dinner so I gave this recipe a try. It was a hit although I would suggest cutting the granulated sugar by half so you might actually taste the sweet potato goodness!
