This is a traditional, North-American side dish that is usually served during Thanksgiving dinner. The casserole consists of mashed sweet potatoes, usually blended with brown sugar, topped with a streusel topping, pecans, and marshmallows.

The dish tastes sweet, almost like a dessert. It is a classic recipe during the holiday season, and it blends perfectly with oven roasted turkey or other meats.

For exact ingredients measures and steps, please follow the recipe card below. Also, watch the short video tutorial attached as it will guide you better through the cooking process. The general steps are as follows:

  1. Cooking the potatoes – first, decide on a cooking method for the potatoes. Clean, peel and cook the potatoes.
  2. Toasting the pecans – preheat the oven, measure two cups of pecans, lay them on a baking sheet and toast in the oven for a few minutes. Check on them often to not burn them. Toasting the pecans is optional, but it will add more flavor to the dish.
  3. Prepare other ingredients – while the potatoes are cooking, gather the ingredients for the casserole. Melt the batter, slightly beat the eggs and measure the sugar and milk.
  4. Cinnamon filling – while they are cooking, mix the cinnamon sugar filling and set it aside.

This is hands down the best Sweet Potato Casserole I've ever made! This will definitely be my "go to" recipe from now on! I added a layer of the marshmallows in the middle and it was perfect! The only problem was there were no leftovers!

I actually make this recipe for Thanksgiving, Christmas, Christmas parties during the fall and winter months. Might I say that it is the best recipe for sweet potato in the world LOL. Why I just finished making a double batch for a post x mas party tonight. Night shift! It's a bit of work, but totally worth it. Thank you for the recipe.



Can you use yams instead of sweet potatoe?



Question: is there any harm in leaving out the pecans? Our sweet potato lover is also allergic to nuts so I'm always looking for a sweet potato casserole recipe that she can enjoy.


You can make it without the pecans!



Did you end up using oats?


Not in this recipe, but I tried it and it tastes great.

I was asked to bring a vegetable side to a Xmas dinner and after seeing sweet potato casserole in many American holiday based movies and tv shows I thought I’d bring one to my parents for a joke. It looks and smells wonderful, but not sure how this is going to go down for us Canadian/ Brits. Everyone here loves sweet potato, just not sure about the rest of the sweet.. recipe was easy, straightforward and looks just like the pics. Maybe let you know how it went down later.. cheers from Canada.. Merry Christmas



d when is white sugar instead of brown sugar used when mixing sweet potatoes, and how does it effect the recipe


brown sugar has more flavors and some caramel notes, but you can use white if you don't have brown on hand.
