Step One: Prepare the Potatoes

Variations and Add-ins for Classic Sweet Potato Casserole
Cooking the sweet potatoes: Instead of boiling the potatoes, you can just roast them whole on a baking sheet in a 425 f oven until they are tender when a fork is inserted in the center. Then just peel and mash them up.
Orange flavor: We use orange juice in the casserole to give it the slightest hint of that flavor, But, if you like more of an orange sweet potatoes casserole, you can add in some orange zest from fresh oranges or even some orange extract.
Streusel topping: If gooey marshmallows aren’t your thing and you prefer a topping with crunchy pecans, you can make a delicious streusel pecan topping. Just add chopped pecans, a little bit of flour, some melted butter, and brown sugar in a food processor and mix until it makes a crumbly, streusel-like topping. This Sweet Potato Casserole has a pecan and brown sugar topping you may want to try.
Maple syrup: Sweet potatoes and maple syrup go hand in hand if you ask me. You can add a small drizzle to the soft sweet potatoes along with all the other ingredients.
Can I Freeze This Southern Sweet Potato Casserole?
This is a wonderful dish to make ahead of time. You can mix it all up the night before then just bake it the next day. But you can also freeze it if you’re needing to make it weeks in advance.
To do so, just prepare it according to the instructions, but leave off the marshmallows. Wrap the whole casserole in plastic wrap then with a layer of foil and freeze it for up to a couple of months. For best results, you’ll want to thaw it overnight in the fridge before adding the marshmallows and baking it.
Can I Use Canned Sweet Potatoes Instead?
If you find yourself in a pinch for time, you can definitely use canned sweet potatoes. If you’re using the ones canned in syrup, I recommend draining them and rinsing them before mashing them up. This prevents the casserole from be way too sweet!
Are Yams and Sweet Potatoes the Same Thing?
Some people may be surprised to know the two are totally different vegetables. So how do you tell the difference? Well, good news is, what you find at most grocery stores in the United States are actually sweet potatoes. But here are the differences in the two in case you’ve ever wondered:
- Skin – Yams have a brownish peeling that looks sort of like tree bark. Sweet potatoes skin is mostly smooth and tan or orange in color.
- Flesh – Most of the time, true yams have a white or off-white color interior. You’ll also find some that have a purple of pink flesh. The flesh of a sweet potato is pale orange that darkens to a deeper color of orange when it’s cooked.
- Shape – Sometimes you’ll see yams that are shaped like sweet potatoes but for the most part, yams are more of a thick like cylinder shape.
- Taste – Yams have a much more neutral flavor than sweet potatoes which make them perfect for more of a savory sweet potato casserole or roasted with different root vegetables.
