To prepare a zesty sweet potato cheesecake recipe, you'll first need to prepare the sweet potatoes. Peel and cut the Sweet Potatoes in half lengthwise. Cut each half into 1/4-inch slices. Scoop out the flesh from the center of each slice. Place the slices in the bottom of an 8x8x2-inch baking dish. Pour the sour cream over the top of the pie. Bake for 35 to 40 minutes, or until the filling is bubbly and the topping is golden brown. Serve with whipped cream.
