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!

  • We made this around the holidays. It’s so fabulous it could almost sit alone in the dessert category, too. The pecans really balance the sweetness well.

  • This will be on our dinner table this Thanksgiving!

  • I was never a sweet potato fan until last year when I was introduced to some “outside the box” recipes. Now I know how good sweet potatoes can be, and this recipe looks great. Will definitely try it this holiday season.

  • Made the sweet potato pecan crisp for Thanksgiving dinner today. It was fantastic, very similar to one I’ve made in the past, but yours was much better. I just halfed the topping recipe. was able to make the sweet potato a day earlier and just added the topping before baking. My guests loved it. Thanks for another great recipe. Have tried several and they are all great. thanks,

  • Jenn,
    I really feel like you should do a cookbook at some point. I have tried so many of your recipes, and they are all amazing!!

    I’m making your sweet potato crisp, roasted carrots with thyme, and roasted brussels sprouts for Thanksgiving.
    For Christmas Eve, I’ll have Hot Buttered Apple Cider ready for my guests to enjoy, and later we’ll enjoy your mac n cheese as a side dish.
    And pretty much everyday I’ve been eating pumpkin muffins (made from your pumpkin bread recipe) for breakfast.

    I think it’s safe to say that I am a major contender for Once Upon a Chef’s biggest fan!

    Best regards,
    Danielle Foster

  • I have been making this dish, mostof my adult life. Not exactly the same but very close. It is just as good cold or even the next day. Wonderful side dish or desert. In my recipe though I also add some FROSTED FLAKES to the topping mixture. Just add it in with the other ingred. it makes for the best topping ever. Try it, you will surely love it.
