Mashed Sweet Potatoes with Sage and Walnut Topping

mashedsweetpotato.jpgThanksgiving isn't complete without some sort of sweet potato dish. There's the traditional marshmallow-topped sweet potato side dish or the classic dessert of sweet potato pie. Sweet potatoes are almost magical when cooked or baked. Their bright orange flesh turns soft and almost creamy. Roasting them heightens their natural sweetness even more. Many holiday recipes further improve upon the sweetness by adding brown sugar, honey, or maple syrup. With the holiday only one week away, it's time to start planning. I'll be making a few new recipes to add to my repertoire.

Sweet and savory flavors are the basis of many classic Thanksgiving recipes. This side dish strays from the typical in favor of something a bit more gourmet and savory. Roasted sweet potatoes are mashed with butter, cream, and maple syrup and then spread in a gratin dish. The mashed sweet potatoes are then topped with fluffy panko breadcrumbs, fresh sage, and chopped walnuts. It's then drizzled with melted butter and broiled, turning the top golden and crunchy. It's a side dish that's sure to please both sweet potato traditionalists and those looking for a new take on a holiday favorite.

The first thing to know about sweet potatoes is that they are not yams. Yams, which are native to Africa and Asia, are a completely different vegetable. Yams are white and starchy. Sweet potatoes are orange and sweet and are distantly related to white potatoes. This confusion only really exists in North America. Unfortunately the USDA continues to label sweet potatoes and yams, which adds to the confusion. Just know that sweet potatoes are what you're looking for to make this recipe.
