Sweet Potato Crunch Casserole

You had me at brown sugar and pecans!

Many folks consider the turkey to be the true star of the Thanksgiving dinner, and for the most part, they’d be right. But what’s a turkey dinner without side dishes? Arguably the most important part of Thanksgiving isn’t the turkey but everything that surrounds those slices of juicy turkey on our plates. The usual suspects are all there: cranberry sauce, green beans, stuffing, and mashed potatoes. One side dish that is an absolute must at our dinner table is a sweet potato crunch casserole. The name says it all, sweet potatoes topped with a brown sugar and pecan crumble for crunch. Yum-yum!

Not everyone is a fan of sweet potatoes, but this recipe is sure to win over even the toughest of critics. Buttery sweet potatoes are mashed with more butter, brown sugar, and a little buttermilk to make the potato mixture smooth, creamy, and flavorful. While this bakes in the oven, we prepare a crumble topping with a little flour, more brown sugar, and chopped pecans. This bakes into a beautiful brown crust over top of orangy bronze sweet potatoes. It needs to cool down in order to set up a bit before it’s ready to be served to the hungry crowd anticipating a great meal.

If you’ve been asked to bring a side dish to the party, you’ll definitely want to arrive bearing this delicious sweet potato crunch casserole. It’s intended to be a side to the main course, but it has a dessert-like quality in its sweetness, making dinner extra indulgent. With all of the savoriness going on our dinner plates, it’s sometimes nice to have a contrast of sweetness to keep the whole meal nice and balanced. A sweet potato crunch casserole will team up beautifully with a tart cranberry sauce, a side of bright green beans, and of course a generous helping of the main event: the turkey.
