Crustless Sweet Potato Pie, basically a sweet potato pie that has no crust.  It falls into the category of the famous Impossible Pies that was the rage from the introduction of Bisquick in the 80's.  

Sweet Potato Pie

This past weekend I wanted to try out an idea I had with some leftover sweet potatoes.  As Thanksgiving is approaching, I know this recipe is going to come in handy. Don't get me wrong--we love our leftovers, but there is a thing about you can only eat so many sweet potatoes, so that is how I came up with making this pie.  

Did you know that you can make a Sweet Potato Pie without a crust?  Yes, you can make a Crustless Sweet Potato Pie sometimes called Impossible Sweet Potato Pie. 

Sweet Potato Pie

Crustless pies have been around for years. The first ones I made was in the 80's using Bisquick, a Coconut Crustless Pie and don't forget the Impossible Bacon Pie.  

As the years go by, these crustless pie recipes become classics.  Basically, a crustless pie is made with an egg custard base, and a flour of some sort, all purpose or gluten free, is added so that when baked, forms its own crust. You can even take leftover  Sweet Potato Casserole and use it in a Crustless Sweet Potato Pie.  Just measure as you would for ordinary sweet potatoes use less sugar.
