Sweet Potato Casserole Ingredients
Here’s what you’ll need to make this top-rated sweet potato casserole with marshmallows:
- Sweet Potatoes: You’ll need about five sweet potatoes, peeled and sliced.
- Brown Sugar: Brown sugar is essential to the cozy, toasty, warmth we’re after when we make sweet potato casserole. Use light for a milder flavor or dark for a more intense flavor.
- Margarine: This recipe calls for reduced-fat margarine, but you can substitute regular butter if that’s what you have on hand.
- Orange Juice: Three tablespoons of orange juice gives this sweet potato casserole subtle brightness.
- Cinnamon: Just a pinch of cinnamon adds warmth and brings out the other flavors.
- Marshmallows: Of course, you’ll need a bag of miniature marshmallows (they’ll be the star of the show, after all).

“Made this last year and it was delicious,” says Kathy. “So easy to do and can be made the day before. Just add the marshmallows and bake and serve. Easy, simple, and a great hit. Doing it again this year!!”
“Fabulous,” raves TUCCI013. “It was a bit different from the sweet potato casserole of my childhood: I wasn’t accustomed to the OJ, but I found it to be the perfect addition. I added a layer of pecans and brown sugar under the marshmallows — YUM!”
“This recipe is amazing,” according to anne365. “Definitely a keeper, although I did make one slight change: I didn’t have any orange juice on hand, so I used about a teaspoon of fresh lemon juice instead.”
