Sweet Potato Casserole Recipe

Sweet Potato Casserole is my favorite side dish at the Thanksgiving or Christmas table. When else do you get to eat basically a dessert and call it a side dish? I like using that excuse and add a hefty amount of this creamy goodness to my plate. 

There are many Sweet Potato Casserole recipes floating out there, however, once you try this one, you won’t need any other recipe ever. This casserole is loaded, in a good way. The potatoes are boiled and mashed, blended with some brown sugar, nutmeg, and cinnamon to elevate the fall flavors.

The best part of this casserole is the surprise brown sugar cinnamon filling, a delicious, mid-layer of cinnamon goodness. The topping is another highlight of this casserole. Made with toasted pecans, sweet marshmallow and more of the delicious cinnamon sugar filling mixture. Thanksgiving isn’t complete without a Homemade Sweet Potato Casserole. So, give this one a try, and you will see why it is so special! 

What is Sweet Potato Casserole?

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. 

How to prepare sweet potatoes for Sweet Potato Casserole?

  • First clean, peel and dice the potatoes
  • Wash them in cold water to remove some of the starch
  • Add diced potatoes to a dutch oven or large saucepan
  • Cover with water and boil until tender

Another way to prepare the sweet potatoes is by cooking them in the Instant Pot. You can use my Instant Pot Sweet Potato recipe. The sweet potatoes can also be baked, I just find that method more time to consume and resulting in a few dried potatoes.

How to make Sweet Potato Casserole?

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.
  5. Pecan topping – once the pecans have been toasted and chopped, use one cup to prepare the pecan topping.
  6. Assembling – combine all the ingredients for the casserole and layer it into the prepared baking dish.
  7. Baking – bake for 20-30 minutes is enough. Remove from oven and cover with foil to keep it warm. Spray the foil first with baking spray, to avoid marshmallows sticking to it.

Can you make Sweet Potato Casserole in advance?

Yes, the casserole can be made a few days in advance.

You can choose to just assemble it, wrap tightly in plastic wrap and bake when ready. If you do refrigerate it before baking, we would suggest removing it from the fridge at least 30 minutes prior to baking.

Also, you can bake it first, and let it fully cool. Then, wrap tightly in plastic wrap and refrigerate it. Cover with foil and warm it up in the oven before serving.

Amazing casserole, made this today and it is perfect!



What a delicious dish this is! My family came over the weekend and I wanted to use some sweet potatoes, and was looking for an easy and quick casserole! This one was superb! Super flavorful, it has the right amount of sweetness, it is buttery, and the topping is great! We love pecans so we used quite a lot of them, it made the casserole even crunchier, which is perfect when combined with the marshmallows! Also, had some leftover and enjoyed it this morning. All in all a gret recipe, and i am sure it will be now my family’s most requested sweet potato dish from now till Christmas time:))!!! Thanks


Thank you Sarah for your feedback! We are delighted that you and your family loved it. For sure, this is the main, classic Thanksgiving dish, that should be enjoyed by everyone!



This looks awesome! My potatoes are cooking in the crockpot now and I'm debating on whether or not to assemble the casserole today for Thanksgiving (2 days from now). Or maybe leaving everything separate and putting it together the day of? If I were to assemble ahead of time (today) how do the cinnamon and pecan layers hold up? I worry that things will get a little soggy in the fridge. What do you think would be best? Thanks!


It will hold up greatly! You can assemble it fully and just cook when you want to serve it!!



What an amazing dish. We had plenty of sweet potatoes to use, so this casserole was the perfect fit. It is buttery and very flavorful. We enjoyed it a lot! 👍👍👍


Kristina McClatchie

Julie Fassio

Can walnuts be substituted?

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!


haha yes no leftovers with this one, so happy that you liked it!!

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.
