Sweet Potato Casserole with Marshmallows

To make ahead: Prepare the recipe through Step 4, then cover the casserole with plastic wrap and refrigerate for up to 3 days. Bake for 45 to 50 minutes, or until hot all the way through. Top with marshmallows and bake for a few more minutes until the marshmallows have melted.

  • Prep time: 15 minutes
  • Cook time: 45 minutes
  • Yield: 8 to 10 servings

Ingredients

  • 8 sweet potatoes (about 4 pounds)
  • 1/4 cup plus 1 tablespoon unsalted butter, softened at room temperature
  • Finely grated zest of 1 orange
  • 1/2 cup fresh-squeezed orange juice
  • 1/2 teaspoon salt
  • 1/8 teaspoon pepper
  • 4 cups large marshmallows (about 12 ounces), cut in half with scissors

Method

1 Roast the sweet potatoes: Preheat the oven to 425ºF. Line a baking sheet with parchment and spray it with vegetable oil spray.

Scrub clean and dry the sweet potatoes. Slice them in half lengthwise.

Place the potato halves, cut side down, on the baking sheet. Prick each in several places with a fork and bake for 40 to 45 minutes, or until soft. Remove and let rest until potatoes are cool enough to handle.

2 Lower the oven temperature to 375ºF. Butter or coat with cooking spray a 3-quart or 9-x13-inch baking dish.

3 Remove the sweet potato skins: As soon as the potatoes are cool enough to handle, pull off the skins and discard. Transfer the inner flesh to the bowl of a stand mixer bowl fitted with the paddle attachment, or a large bowl.

4 Mash the potatoes: Add 1/4 cup of the butter, orange zest, orange juice, salt and pepper. Mix on low speed in the stand mixer until the potatoes are creamy, but not necessarily perfectly smooth. Taste and add more salt and pepper, if you like. Transfer the potatoes to the buttered baking dish.

Alternatively, mash with a potato masher and beat until creamy with a wooden spoon, then transfer to the baking dish.
