A creamy whipped Sweet Potato Casserole with buttermilk and cinnamon. Top with your choice of marshmallows or crunchy pecan praline.
Confession: Thanksgiving dinner has never been about the turkey for me. Sure, it’s the attention-hog of the feast. We agonize over it for days before our guests arrive, bathing it in buttermilk soaks and cider brines. We lovingly baste it for hours as it roasts to juicy, golden perfection (so we hope), before carving it up and presenting it as the glorious centerpiece to our holiday tables.
It’s good. Delicious even.
Despite all of the anticipation surrounding that eponymous bird (it is, after all, “Turkey Day”), I never eat more than one slice. For the best flavors of Thanksgiving, I go straight to the sides.
Sweet Potato Casserole has been a staple on our Thanksgiving table for as long as I can remember. I’m sure my initial attraction to the dish had nothing (everything) to do with the novelty of getting to eat marshmallows for dinner (“jackpot” to a four-year-old).
As a 30-something, I still dive fork-first into this casserole every year. The whipped potatoes are creamy and gently spiced, while the buttermilk lends a light tang to complement the sweetness. It’s a win-win for guests of all ages.
Did I mention that it’s easy? The recipe starts with cooked sweet potatoes. Use whatever method you prefer—boiling, microwaving, baking. I use an electric pressure cooker. It’s fast and frees up the stove for other uses.
In a pinch, canned yams (plain, not candied) can be substituted. Beyond that, the process is little more than Mix-Bake-Eat, leaving plenty of time and energy left to tend to that fussy turkey.
As for the topping? While toasted marshmallows make me nostalgic for my childhood, I’ve since come to love this casserole topped with a pecan praline crust. Instructions for both variations follow, so you and your family can choose your favorite.
The recipe makes a pretty big bowl, but worry not, the casserole also reheats well the next day. You may or may not catch me eating a scoop of these for breakfast every year on Black Friday. I plead the Fifth.
