    Orange-Spiced Sweet Potato Casserole

    Jump to Recipe Print Recipe

    Orange-Spiced Sweet Potato Casserole is an easy side dish that's delicious with a holiday meal, or any meal all year long. It combines naturally sweet mashed sweet potatoes with orange zest, butter, brown sugar and a touch of nutmeg and cinnamon. But it's the pillowy peppered marshmallows and crunchy pecans on top that just might steal the show.

    Ingredients for orange-spiced sweet potato casserole

    Choosing Sweet Potatoes

    You'll need about three pounds of sweet potatoes for this recipe, and since the size of each potato varies that may mean three large ones or 4-5 smaller, slender sweet potatoes. Use a scale in the produce section of your grocery store to be sure you buy enough.

    Prepping the Sweet Potatoes

    Oven roasting or baking helps to caramelize the natural sugars in sweet potatoes and it helps bring out the ultimate sweetness in this casserole.

    In a pinch, you could also microwave the sweet potatoes until tender, just use the potato cooking option on your microwave oven.

    You can tell the sweet potatoes are cooked once a fork easily slides into the potato. It will need to be tender and soft.

    Top Tips and FAQ

    Can I use yams instead of sweet potatoes?

    Yes. Although there is often confusion about the two, the yams that we buy in a standard U.S. grocery story are almost always just a different variety of sweet potato and yes, they will work great in this recipe.

    Scroll down for more details on the difference between yams and sweet potatoes.

    What about using canned yams?

    I've not made this recipe using canned yams, but if time is short I imagine that would be OK to substitute. You'll need about 6 cups of mashed, canned sweet potatoes or yams.

    Can this be frozen ahead and prepared later?

    Yes, simply leave the marshmallows and pecans off and freeze the sweet potato mixture in a freezer-safe dish. Defrost, then bake according to the recipe below.

    Mashed sweet potatoes in a bowl with a fork

    Mash or Smash

    Place the baked sweet potato filling in a large mixing bowl. I like to smash the sweet potatoes by hand using a potato masher and leave a few chunks of sweet potato in the filling. I like it a little lumpy.

    But my family prefers the filling to be fluffy and more like mashed potatoes.

    Add the remaining ingredients, except the marshmallows and pecans.

    If you like a soft, fluffy casserole - similar to the consistency of mashed potatoes - then use a hand mixer to blend the ingredients until you get the texture you like.

    I think this recipe is equally delicious when the ingredients are combined using a potato masher. It depends how you and your family prefer it.

    Either way, spread the sweet potato mixture evenly in a 13" x 9" glass baking dish or any oblong, 3 quart baking dish.

    Peppered Marshmallows

    Mini marshmallows in a bowl with orange zest and pepper

    Here's the secret to making your sweet potato casserole stand out in the crowd of holiday side dishes. Add pepper to the mini marshmallows then toss them with one teaspoon of orange zest.

    Each little pillowy marshmallow gets a light dusting of pepper and a touch or zest.

    It's a technique that gives candy-like marshmallows a savory touch.

    Spread the peppered marshmallows evenly across the top of the mashed sweet potatoes.

    A great side dish any time of year

    We often think of sweet potato casserole as a Thanksgiving or Christmas side dish, but since this recipe includes a touch of citrus and light spices it's delicious any time of year.

    Serving Suggestions

    Serve your Orange-Spiced Sweet Potato Casserole with turkey, prime rib, roast beef, ham or pork chops.

    The Difference Between Yams and Sweet Potatoes

    If you buy sweet potatoes from a standard U.S. grocery store, the odds are incredibly good that you will bring home a variety of sweet potato that will work beautifully in this recipe.

    Don't worry if you see them labeled as yams. The word yam is sometimes used to differentiate the soft variety of sweet potato from the firm variety.

    These were sold side-by-side in the grocery store, but the yams on the left are simply a different variety of sweet potato.

    But it gets confusing. Even canned yams are simply a different variety of sweet potatoes. But they are labeled as yams.

    To try and lessen the confusion, the U.S. Department of Agriculture requires labels with the term ‘yam’ to be accompanied by the term ‘sweet potato.’

    But true yams are native to Africa and Asia and have rough brown peels, almost like tree bark, (photo below) they have white flesh and a neutral flavor. They also won't work as a substitute for a recipe calling for sweet potatoes. These yams are often sold sliced, wrapped in plastic wrap and refrigerated.

    Unless you specifically search for true African "yams," which are usually found in an international market, rest assured, you are probably buying and eating sweet potatoes!

    Idaho Sweet Potatoes?

    The Crinkled Cookbook is based in Idaho and yes, our state is oh so famous for potatoes. But do sweet potatoes grow here? Nope. Not so much.

    Sweet potatoes are actually more closely related to the carrot than potatoes and they don't do grow well in Idaho because it takes about 150 frost-free days to grow sweet potatoes. It's pretty hard for Idaho weather to meet those conditions.

    The majority of U.S. sweet potatoes are grown in the southern states. Thank you North Carolina!

    Author: Melinda O'Malley Keckler

    Ingredients 

    • 3 pounds sweet potatoes
    • 5 tablespoons unsalted butter sliced
    • ½ cup light brown sugar
    • 2 teaspoons orange zest divided
    • ½ teaspoon cinnamon
    • ¼ teaspoon nutmeg
    • ¼ teaspoon salt
    • 3 cups mini marshmallows
    • ¼ teaspoon pepper freshly ground
    • ½ cup chopped pecans

    Instructions

    • Preheat oven 375° F
    • Line a baking sheet with foil or parchment paper.
    • Rinse the sweet potatoes, leave the peels on, and use a fork to prick holes in each one. Bake for 60 minutes or until a fork easily slides into the sweet potato. As an option, place the sweet potatoes on a paper towel in the microwave and use the potato setting on the microwave to cook until soft enough for the fork to slide easily into the potato.
    • Remove from the oven and cover lightly with a piece of aluminum foil. Cool the potatoes for 10-15 minutes. Using a small knife to slice the skins, they should easily separate from the sweet potato filling and the skins should come off easily.
    • Scoop out the sweet potato flesh and place in a large bowl. Add butter, brown sugar, 1 teaspoon of orange zest, cinnamon, nutmeg and salt. Use an electric mixer and whip until the the butter is melted and the potatoes are the consistency of mashed potatoes.
    • Grease a 9” x 13” baking dish or spray with Pam.
    • Spread sweet potato mixture into the baking dish.
    • In a medium-sized bowl, place marshmallows, the remaining 1 teaspoon of orange zest and ¼ teaspoon of pepper. Toss until the marshmallows are lightly seasoned with the zest and pepper.
    • Spread the marshmallows across the top of the sweet potato mixture then sprinkle with the pecans.

    Bake

    • Place in a 375° F oven for 15-20 minutes or until the marshmallows are lightly browned.

    To Make Ahead

    • Bake the sweet potatoes and follow each step in the recipe except for adding the marshmallow topping. Cover the sweet potato and refrigerate for up to two days ahead.
      About an hour before you plan to serve the casserole, remove the dish with the sweet potato mixture from the refrigerator. Let the dish sit at room temperature for 30 minutes.
      Preheat oven to 375° F.
      Add marshmallows and pecans. Cover with foil and bake for 15 minutes. Uncover and bake for another 10 - 15 minutes or until the marshmallows are lightly browned. Watch closely during the last few minutes to ensure the marshmallows don't burn.
