As a kid I LOVED marshmallows. So at Thanksgiving, the Sweet Potato Casserole was my favorite side dish. Yes, I also liked the traditional Thanksgiving dishes:

• turkey
• green bean casserole
• roasted brussels sprouts
• glazed carrots
• squash casserole 
• mashed potatoes
• creamed corn
• cranberry fluff
• cornbread dressing
• pumpkin pie
• Pumpkin Praline Bread Pudding
• Eggnog Tres Leches Cake
• Thanksgiving desserts

However, the Sweet Potato Casserole totally rocked! It is still a favorite out of all of my sweet potato recipes!

When I was maybe about 7 or 8 years old, my job at Thanksgiving was to add the marshmallows on top of the sweet potatoes and then I would scarf a couple of marshmallows for myself also. 🙂

So when it came to adding marshmallows (one of my favorite things in the world) in my 7 or 8-year-old mind, the more marshmallows the better!

So one year while no one was looking, I added more marshmallows, and then just a little more, and maybe a little more…as many as I could fit on top. I think I emptied the entire bag. Then in the oven, they went.

And the hardest part (especially to a kid) was the waiting. So I waited and waited.

Then the next thing I know I hear this BOOM! And then I smelled this horrible smell…..the smell of burning marshmallows.

My sister opened the oven door and the marshmallows had exploded all over the oven. The entire oven was covered with black burning marshmallows.

However, that mishap did not deter us. This Sweet Potato Casserole continued to be on our Thanksgiving table every year, year after year without any more marshmallow mishaps.

How could we not have it on the table? This Sweet Potato Casserole with Marshmallows was part of our Thanksgiving traditions.

Tips for the Perfect Sweet Potato Casserole

I will share just a few tips.

First, I recommend using fresh sweet potatoes. Yes, it can totally work with canned yams or canned sweet potatoes, but to me, the flavor of the fresh sweet potatoes is better.

Don’t overload the marshmallows. I recommend just 1 layer of marshmallows on top. Don’t stack the marshmallows on top of each other, unless you want a marshmallow casserole with a few sweet potatoes. If that is the case, then go ahead. Who am I to judge?

Make Ahead Sweet Potato Casserole

To manage time, I recommend baking the sweet potatoes the day before. You can even assemble the whole casserole, except for the marshmallows, the day before and keep refrigerated until you are ready to bake.

How To Cook Sweet Potatoes For Sweet Potato Casserole

You have a couple of choices when it comes to cooking the sweet potatoes for this dish.

1. Roast the sweet potatoes. This is my preferred method if I have time. It is a great option if you are making the Sweet Potato Casserole a day or two ahead of time.
2. Boil the sweet potatoes. If you don’t have as much time, you can peel and quarter the sweet potatoes and boil them on top of the stove. This is the method used in the video.

How To Make Sweet Potato Casserole With Marshmallows

1. At Thanksgiving, this sweet potato casserole with marshmallows is one of the dishes that I make a day before Thanksgiving. It lends itself perfectly to being made ahead of time.
2. Cook and mash the sweet potatoes a day ahead of time.
3. Mix together the sweet potato filling and assemble the casserole a day ahead of time. (I usually leave the marshmallows off the casserole until right before I put them in the oven.)
4. Then on Thanksgiving Day, all you have to do is add the marshmallows on top and bake the casserole in the oven. All the heavy lifting was done ahead of time.

Variations On Sweet Potato Casserole With Marshmallows

1. Add a Pecan Streusel.  One of the most popular variations on the sweet potato casserole is to add a pecan streusel in addition to the marshmallows. That gives it a sweet crunchy texture in addition to the sweet, creamy goodness.

How To Make a Pecan Streusel For Sweet Potato Casserole

1. In a bowl, stir together brown sugar, flour, melted butter, and pecans.
2. Sprinkle over the top of the sweet potatoes and marshmallows.
