How to Make Sweet Potatoes

Sweet potatoes are delicious when roasted, boiled, mashed and even slow-cooked—there are so many ways to make them! Even though sweet potatoes are often associated with Thanksgiving dinner, these colorful root vegetables are year-round favorites due to their mouthwateringly-sweet taste and their versatility in both flavor and preparation.

Wondering how to make sweet potatoes if you’re short on time? Try microwaving them! Just pierce your sweet potatoes with a fork and cook them in the microwave for 8 to 12 minutes, turning them over once halfway through the cooking time. Let them sit for one minute and then add your seasonings! Try serving your sweet potatoes with butter or margarine, brown sugar, maple syrup or honey and any of your favorite spices. We’re big fans of using cinnamon, allspice and nutmeg in sweet potato recipes!

How to Store Marshmallow Sweet Potato Casserole

If you end up with any extra spuds, don’t worry—there’s no need to discard your leftover sweet potatoes with marshmallows! Cooked sweet potatoes can be kept in the refrigerator in an airtight container up to 4 days. Leftover sweet potato casserole can be stored in the freezer in an airtight container for up to 2 months. Marshmallows do not freeze well, so we suggest removing them prior to freezing and adding additional marshmallows at the end of reheating time, if desired.

Ingredients

  • 3 cans (15-oz each) sweet potatoes, drained
  • 1/4 cup butter, melted
  • 1/4 cup firmly packed brown sugar
  • 1/2 teaspoon salt
  • 15 large marshmallows

Steps

  • 1
    Heat oven to 350°F. Spray 12x8-inch (2-quart) glass baking dish with nonstick cooking spray.
  • 2
    Place sweet potatoes in sprayed baking dish. Pour butter over potatoes. Sprinkle with brown sugar and salt. Top with marshmallows.
  • 3
    Bake at 350°F. for 25 to 30 minutes or until potatoes are thoroughly heated and marshmallows are lightly browned.

Tips from the Pillsbury Kitchens

  • tip 1
    Canned sweet potatoes, marshmallows, and a few pantry items make this an easy side dish to throw together.
  • tip 2
    No large marshmallows? Use 1 1/2 cups mini marshmallows so there’s no question everyone will get their fair share of the golden, gooey topping. Sprinkle mini marshmallows to cover potatoes and bake. Keep an eye on them so they don’t start to brown too quickly.
  • tip 3
    If the marshmallows start browning too quickly, loosely cover the baking dish with foil for last 10 minutes of baking time. The shiny nature of foil deflects the heat, slowing down the overall browning of ingredients that are high in sugar or fat.
