Nana's creamy buttermilk-infused sweet potato dish brings total comfort! I've adjusted her traditional recipe by adding tangy buttermilk for that wow factor. Everyone at the table grins when they taste those smooth, spiced sweet potatoes topped with either gooey toasted marshmallows or that crunchy pecan mixture.
The Secret That Elevates This Dish
There's something wonderful when tangy buttermilk combines with sweet potatoes and cozy spices. What's great is how flexible it is—you can go sweeter with marshmallows on top or add fantastic texture with the nutty pecan layer. Whichever way you go, this dish always disappears first during our family holidays.

Delicious Topping Options
You'll win either way with toppings! Marshmallows get beautifully browned and bring that classic holiday feeling, while the pecan mix delivers amazing buttery crunch. I often split the dish down the middle with both toppings so everybody gets what they want.
Handy Cooking Shortcuts
Don't forget to drain those potatoes really well or you'll end up with soggy results. Use a shallow, wide container for maximum topping coverage. And here's a quick trick—warm up your potatoes before mashing and they'll turn out incredibly fluffy.
Smart Prep Strategies
This dish stays good in the fridge for several days after cooking. You can also get the potatoes and topping ready ahead of time and just heat everything up before assembly. This really saves you time when you're busy cooking other holiday foods.
Great Food Companions
This goes amazingly with Thanksgiving turkey or works as a sweet treat with a dollop of whipped cream. Sometimes I pour a bit of maple syrup over the top when I'm feeling fancy. It never disappoints, no matter how you serve it.

It makes the potatoes silky smooth with a slightly tangy flavor, without feeling heavy.

The blend adds a richer, layered sweetness, but using all light brown sugar is totally fine too.
