Marshmallow-Top Sweet Potato Casserole

Ingredients for Sweet Potato Casserole

To make this fan-favorite sweet potato casserole with marshmallows, you'll need the following ingredients:

• 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).

Here’s a quick overview of the steps to make this delectable sweet potato casserole with marshmallows. You’ll find the full, detailed recipe below:

1. Cook and mash the sweet potatoes: Peel and cube the sweet potatoes, then place them in a saucepan and cover with water. Boil over medium-high heat until tender, drain, and mash with a potato masher.
2. Mix and top the casserole: Once the sweet potatoes have cooled, use an electric mixer to combine them with brown sugar, margarine, cinnamon, and orange juice. Pour the mixture into a baking dish and top with marshmallows.

How to Store Sweet Potato Casserole with Marshmallows

To store leftovers, place the casserole in a shallow, airtight container and refrigerate for up to four days. Reheat in the microwave or oven when ready to enjoy again.

Is it Possible to Freeze Sweet Potato Casserole with Marshmallows?

Absolutely! We suggest freezing the casserole before baking and without the marshmallows, which can be added later.

To freeze, prepare the filling as per the recipe and transfer it to a foil baking dish. Seal the dish tightly with foil and freeze for up to three months. When ready, thaw it in the fridge overnight. Add marshmallows and bake as instructed.
