Purple Sweet Potato & Chestnut Pie

I’m surprised I haven’t done this combo before. To be honest, this is super similar to my Kabocha & Chestnut Pie w/ Graham Cracker Oat Crust. Let’s make this Purple Sweet Potato and Chestnut Pie!

The amazing thing about this recipe is how easy and fast it is! You literally need 8 ingredients to make this awesome pie that I honestly eat for breakfast, lunch (if I could pack it well), and dessert!

When you make this recipe, the crust ratio really depends on what you like. This time, I wanted to add more oats as opposed to graham crackers. But, you can definitely use all oat flour, all graham cracker crumbs or a mix like I did.

For the filling, you can honestly use any puree/mash that you have. I used purple sweet potato and chestnut, two that are generally starchier.

This, naturally, means some have more moisture than others. In this case, you need to adjust the amount of water you add (less or more). So, don’t just use the amount of water I used. Add it bit by bit.

I honestly don’t think I have any other notes, that’s how easy this recipe is!

Recipe Notes

  1. You could also use agave syrup or honey (if not vegan).
  2. You could use tapioca starch but that may make the filling slightly chewy.
