To make Patti Labelle Sweet Potato Pies, you will need pre-made pie shells, sweet potatoes, brown sugar, evaporated milk, butter, vanilla extract, cinnamon, nutmeg, eggs, and salt. First, peel and boil the sweet potatoes until they’re tender. Then, drain and mash them in a large bowl. Add brown sugar, cinnamon, nutmeg, salt, and melted butter to the mashed sweet potatoes. Mix this together and add eggs, evaporated milk, and vanilla extract. Mix everything together until it’s smooth. Pour the mixture into the pre-made pie shells and bake for about an hour at 350 degrees. Refrigerate the pies for at least an hour before serving.
