Sweet Potato Casserole with Pecan Streusel

Tested & Perfected Recipes

In this down-home sweet potato casserole, a crunchy pecan streusel replaces the traditional marshmallow topping.

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 is always a big hit. It’s an old southern specialty that graces almost every holiday table.

Instead of the traditional marshmallow topping, I cover the mashed sweet potatoes with a crunchy brown sugar-pecan streusel. It makes the dish! Like most sweet potato sides, this one goes with dinner but you might be inclined to eat it for dessert. It’s “that dish,” the one everyone reaches their fork into long after the meal is done.

What you’ll need to make sweet potato casserole with pecan streusel

I’ve noticed that many grocery stores 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 supermarket, so if you see “yams,” you’re probably looking at sweet potatoes.

Reviews & Comments

  • I made this for the first time this Thanksgiving, and my husband BEGGED me to make it again for Christmas and again for his birthday! The topping is wonderful, but the mashed sweet potatoes themselves also have such a nice flavor. This is a must-make from now on for our holidays!

  • This is among my favorites of Jenn’s recipes! I make it every holiday (even in the spring!) because it is such a crowd pleaser. I have even frozen it and used it well after making it and it is remarkably good out of the freezer – which says a lot about the quality of the recipe, since I have never been encountered another recipe with streusel that freezes well. Thank you for another phenomenal dish that everyone loves!

  • Delicious. Family members who typically don’t eat sweet potato casserole tasted and liked it after hearing others rave over how good it is. This is a keeper.

  • Typically, like others, we only have sweet potato casserole during the holidays. This is one of those recipes that breaks that tradition. My family loved it so much that we make throughout the year, usually accompanied by a pork roast. It is simple and satisfying.

  • I’ve already bought a big can of Bruce’s Sweet Potatoes (Yams). I am sure I can just make your topping and put it on top, but should I add anything to the canned sweet potatoes, too? Thank you! Karen

    • Yes, I’d recommend adding the other ingredients (the butter, salt, sugar, nutmeg, and egg). Hope you enjoy!
