Shepherd's pie is one of the most comforting one-dish, cold weather meals around. I mean, is there anyone who doesn't want to dig into a dish of savory seasoned beef topped with creamy, browned mashed potatoes on a chilly fall evening? The combination is about as comforting as it comes.
This Sweet Potato Shepherd's Pie from Lyniece North Talmadge's The Sweet Potato Lover's Cookbook takes the classic mashed potato topping and swaps it out for mashed sweets. The super savory filling is a mix of ground beef or turkey sautéed with tomatoes, thyme, and an umami blast of Worcestershire and shiitake mushrooms, rich and meaty enough to stand up to the sweetness of the sweet potato topping. This sweet and savory shepherd's pie is one of those recipes that's just asking to be tweaked to your tastes and with what happens to be in the fridge—the filling can be supplemented with extra veggies, and the sweet potato topping enriched with cheese, cream, or fresh herbs. If you happen to have a bowlful of leftover mashed sweet potatoes after Thanksgiving, this recipe is the perfect way to repurpose them.
