Sweet Potato Casserole Recipe Eating. Well. By Eating. Well User. Great low fat recipe. There may be other sweet potato dishes that fit the bill, but this one has been a favorite every thanksgiving for 5 or more years. My mom is on a special diet, but she can have this. It is also easy to modify, as needed to fit individual needs, for example, I have made it gluten free. The only change that I consistently make is oven roasting my potatoes whole first.
