What Is Sweet Potato Casserole?

Surprisingly enough, sweet potatoes weren’t present on the first Thanksgiving. Sweet potatoes are native to Central and South America and colonists from Europe introduced the spuds to the new world. The first time sweet potatoes and marshmallows are mentioned together is in 1917, in a recipe booklet published by the Angelus Marshmallow company.

Sweet potato casserole with pecans is a recipe that originated in the South, and early variations of the recipe included different ingredients like cream or milk. This Southern sweet potato casserole recipe is my belove family recipe, made with brown sugar, maple syrup, buttermilk, and crunchy pecans.

Important Ingredient Notes

A complete list of ingredients with measurements, along with detailed recipe instructions can be found in the recipe card located at the bottom of this post.

  • Sweet potatoes. You will need about 3 ½ pounds of orange-fleshed sweet potatoes for this recipe, which is about 5 to 6 medium sweet potatoes. Sweet potatoes are sometimes labeled "yams" in grocery stores but are, in fact, sweet potatoes.
  • Brown sugar. Brown sugar is granulated sugar with molasses added, which gives it a richer, more caramel-like sweetness. The flavor of brown sugar complements the warm spices beautifully. I made this recipe with light brown sugar but you can also use dark brown sugar or just plain granulated sugar if that is what you have on hand.
  • Pure maple syrup. I recommend using good quality, pure maple syrup for this recipe for the best flavor and not maple-flavored syrup.
  • Eggs. Eggs give the casserole structure and make it sturdy. If you want to make this recipe vegan, feel free to omit the eggs. The casserole will not be as sturdy, but equally as delicious.
  • Vanilla extract. Use good quality pure vanilla extract and not vanilla flavoring. A bad vanilla extract can impart an "off" flavor or even an alcohol-like taste.
  • Spices. I love the flavors that cinnamon, nutmeg, and cloves add to this sweet potato casserole. Feel free to use different spices like ginger, cardamom, or allspice according to what you like.
  • Buttermilk. Buttermilk adds creaminess to the sweet potatoes and also adds the most delicious, subtle tanginess to the dish. If you prefer, you can also use regular whole milk instead.
  • Pecans. The streusel topping for this casserole is made with chopped pecans, which are sweet, buttery, and crunchy and a beloved Southern ingredient. If you are not a pecan fan, feel free to make the crumble topping with different nuts like macadamia nuts, almonds, walnuts, hazelnuts, or Brazil nuts.

How To Make This Recipe

  1. Bake the sweet potatoes. Wash the sweet potatoes, prick them all over with a fork, and bake them on a foil-lined baking sheet at 450°F for about one hour until they can easily be pierced with a fork. Allow the sweet potatoes to cool enough to handle.
  2. Make the sweet potato mixture. Peel the sweet potatoes, place them in a large mixing bowl, and break them apart. Beat the sweet potatoes with the butter using an electric handheld mixer until light and fluffy. Add the sugar, maple syrup, spices, vanilla, buttermilk, and eggs and beat until combined.
  3. Make the pecan crumble topping. Mix together the pecans, sugar, flour, melted butter, cinnamon, and salt in a medium mixing bowl with a fork.
  4. Assemble and bake the casserole. Pour the sweet potato mixture into a buttered baking dish, top evenly with the pecan streusel topping, and bake the sweet potato casserole in an oven preheated to 375°F for 35 to 45 minutes until set in the center and golden brown on top.

Frequently Asked Questions

What is the difference between sweet potatoes and yams?

While you may see "yams" for sale in many American markets, they are almost always sweet potatoes that are labeled yams. Real yams are mainly used in Caribbean and West African cooking.

Real yams are entirely different root vegetables from sweet potatoes that are more like yucca in texture and flavor. They have bumpy, tough brown skin with starchy, not sweet flesh.

Do I have to put eggs in sweet potato casserole?

Sweet potato casserole does need eggs to add structure and sturdiness to the dish. You may omit the eggs to make this recipe vegan, but you will have more of a baked sweet potato mash with a crumble topping. The recipe will still taste amazing, however!

When adding the eggs, be sure your sweet potatoes have cooled and are not still hot when combined with the eggs so that the eggs do not scramble.

Can I make sweet potato casserole ahead of time?

You can prepare and bake this sweet potato casserole as directed up to two days before, wrap it in plastic wrap, and store it in the refrigerator. Reheat the casserole in the oven, covered in foil, for 20 minutes the morning of. Remove the foil for the last few minutes to crisp the top.

How To Store Sweet Potato Casserole

Leftover sweet potato casserole can be stored in an airtight container in the refrigerator for up to five days.

You can also freeze leftover casserole by transferring it to a zip-top freezer bag, removing as much air as possible before sealing. Wrap the freezer bag tightly in plastic wrap and store it in a lying-down position in the freezer. The casserole will keep for up to 3 months in the freezer.

Equipment

  • Baking sheet
  • Mixing bowls
  • Electric handheld mixer
  • Measuring cups and spoons
  • 9 x 13 baking dish

Ingredients
  

  • 3 - 3 ½ pounds orange fleshed sweet potatoes - about 5-6 medium sweet potatoes
  • 6 tablespoons unsalted butter - softened
  • ¾ cup light brown sugar - dark brown or granulated sugar also works well
  • ¼ cup pure maple syrup
  • ½ cup buttermilk - or regular whole milk
  • 1 tablespoon vanilla extract
  • 2 teaspoons ground cinnamon
  • ½ teaspoon ground nutmeg

Pecan Crumble Topping

  • 1 cup chopped pecans
  • ¾ cup light brown sugar - or dark brown sugar
  • ½ cup all-purpose flour
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt
  • ¼ cup unsalted butter - melted

Instructions
 

  • Prepare the sweet potatoes by scrubbing them clean, pricking them all over with a fork, and placing them on a foil-lined baking sheet. Bake them in an oven preheated to 450°F for about 1 hour or until they can easily be pierced with a fork. Allow the sweet potatoes to cool enough to handle.
  • Lower your oven temperature to 375°F. Spray or butter a 9x13 baking dish and set it aside.
  • Peel the sweet potatoes and add them to a large mixing bowl. Use the beaters of an electric handheld mixer (with the mixer turned off) or a fork to break the sweet potatoes apart. Add the softened butter and beat the sweet potato mixture on medium-high with the handheld mixer for 2-3 minutes until light and fluffy.
  • Add the brown sugar, maple syrup, vanilla, cinnamon, nutmeg, cloves, salt, and eggs to the bowl with the sweet potatoes and beat on medium-high until well combined. Pour the mixture into the prepared baking dish, smooth it out into an even layer, and set it aside.
  • Add the pecans, brown sugar, flour, salt, and ground cinnamon to a small mixing bowl and mix with a fork until combined. Pour in the melted butter and continue mixing until a crumbly texture is reached.
  • Spoon the streusel topping over the sweet potato mixture in an even layer. Bake the casserole in the preheated oven for 35-45 minutes or until the casserole is golden brown and bubbly. Allow the casserole to cool for about 10 minutes then serve warm.

Notes

  • The sweet potatoes can be baked a day in advance for this recipe.
  • Use good-quality pure maple syrup and pure vanilla extract for the best flavor.
  • Leftover sweet potato casserole can be stored in an airtight container in the refrigerator for up to 5 days.

      Hi Kelli,

      You may omit the eggs! There is no need to replace them with anything. The casserole may be a little less sturdy but equally delicious. I hope you enjoy!
