Give your holiday sweet potato casserole a major upgrade by swapping the marshmallows for a brown sugar pecan streusel—it’s a game changer!

When it comes to Thanksgiving dinner, I think most of us would say, “Don’t get fancy on me, just make the standards really special.” That’s why this down-home sweet potato casserole recipe is always a big hit. It’s an old Southern side dish that graces almost every holiday table. Instead of the traditional marshmallow topping (yes, a classic, but let’s be honest, a gourmet dish marshmallows do not make!), I cover the sweet potatoes with a crunchy brown sugar-pecan streusel. It absolutely makes the dish. Like many Thanksgiving sweet potato sides, it’s almost sweet enough to be dessert. In my house, it’s “that dish”— the one everyone reaches their fork into long after the meal is done.

“My mom and I used your recipe for Thanksgiving and loved it so much that we are making it again for Christmas. Thank you for such an easy, delicious dish that we will enjoy for years to come!”

What You’ll Need To Make Sweet Potato Casserole

Sweet potato casserole ingredients including butter, eggs, and pecans.
  • Sweet potatoes – Note that most supermarkets use the names “sweet potato” and “yam” interchangeably. This can be confusing since yams aren’t sweet potatoes at all, but rather thick white tubers with dark brown skin. Chances are you won’t find real yams at the grocery store, so if you see “yams,” you’re probably looking at sweet potatoes.
  • Unsalted butter – Adds richness and flavor to both the sweet potato base and the streusel topping.
  • Salt – Enhances the flavor of the sweet potatoes and balances the sweetness.
  • Light brown sugar – Sweetens the base and adds a warm, molasses flavor to both the sweet potatoes and the crunchy streusel topping.
  • Ground nutmeg – Adds a hint of warmth and spice to the sweet potatoes, complementing their natural flavor.
  • Eggs – Help bind the sweet potato mixture and give the casserole structure.
  • Flour – The base of the streusel topping.
  • Ground cinnamon – Adds a warm, spiced flavor to the streusel topping.
  • Pecans – Incorporated in the streusel topping to lend a crunchy, nutty contrast to the sweet potato base.

Make-Ahead, Storage & Freezing Instructions

The assembled casserole can be refrigerated for up to 2 days or frozen for up to 3 months. If refrigerated, allow it to sit at room temperature for 30 minutes before baking. For a frozen casserole, thaw in the refrigerator overnight. In either case, add a few extra minutes to the baking time. For best results, bake just before serving.

For leftovers, cover the casserole with foil and reheat in a 350°F oven for about 20 minutes, or until warmed through. If you want a crispier topping, remove the foil for the last 5 minutes of reheating. It’s also delicious as a snack cold from the fridge!

  • I doubled the recipe so I could make two casseroles-one with the streusel and the other with a marshmallow topping for my daughter. For the 2nd one when do I put the marshmallows on? Before I bake or after and then broil? Thx

    • Hi Suzanne, I’d bake it for 20 minutes, top it with marshmallows, and then finish baking another 20 minutes. Hope everyone enjoys!

  • Thanks for replying to my question about adding a bottom layer! Any advice or direction you can give? Would a graham cracker or pecan (like your pumpkin torte) bottom layer taste best? Would I use the same quantity of ingredients that would work for a pie crust?
    Thanks again!!

    • You could go with either the graham cracker or pecan crust, but I may go the graham cracker route as you’ll have pecans topping the casserole. Keep in mind that this will make this dish taste even more like a dessert. And, yes, I’d use the same quantities that you would for a pie crust. 🙂

  • I always make this recipe for the holidays. These are the most flavorful sweet potatoes I’ve ever made. I never boil my sweet potatoes, I bake them at 425 for about 50 minutes on a parchment paper lined sheet, then I scoop out the insides. When I first made them I boiled the potatoes but found that baking them they taste the same and so much easier.

    • I love this idea 👍

    • I used your suggestion last year (2022), and had to find the post again for this year’s baking. Thanks for the tip, works perfectly.

    • When you bake the sweet potato, do you fork holes in it prior to the bake?

        • Re2 quart cssserole: is this a deep casserole or flat like a 9×9 baking pan? I have no idea which dish to use.

          • The baking pan should be about 2 inches deep.

  • Like everybody else, I love this casserole just the way it is! But I have some kids that don’t like nuts. Could I do everything as written except just put a perimeter of nuts around the edge and leave the center plain?

  • Hi Jenn-

    Is it possible to make this with a marshmallow top along with the streusel if I have a kid who loves the marshmallow?

    • Hi Suzanne, I think it would be too much with both the streusel and the marshmallow; I suppose you could cover half in the streusel and half with marshmallows.

  • Hi, Jenn,
    Could I use half the sugar in this recipe?
    Thanks!

    • Yep that’s fine. Enjoy!

  • Roast the sweet potatoes! The flavor is better.
    I have a nearly identical recipe. It’s a big favorite. The one thing I do differently — I roast the sweet potatoes. Let them cool a little. Then peel with a paring knife (the peels almost fall off). Then I mash and mix everything in my standing mixer. It’s easy! You can make ahead, so don’t worry about the the roasting taking up time and space in your oven on the big day. I also used only about half as much brown sugar. It’s still plenty sweet and good.

  • Question: Am allergic to nuts, what can I substitute? Would pumpkin or sunflower seeds give it the crunch, or should I just leave it out?

    • Hi Toby, You can use sunflower seeds if you’d like but it’s perfectly fine to omit them or replace them with oats. 🙂

  • Could this be prepared in a crockpot?

    • Hi Joan, I don’t think this is a great option for a crockpot — the topping wouldn’t crisp up at all (and that’s the best part).

  • I love sweet potatoes/ yams, however like them more plain. I love love all your recipes! This seems like it would be really sweet? Thoughts?

    • Hi Calley, So glad you like the recipes! Yes, this is definitely sweet so if you prefer something more plain, you could try this recipe (which has a hint of sweetness due to the maple syrup but is definitely not as sweet as the casserole).

      • Thanks, that sounds like a good option!
