Slice the pumpkin into slim wedges about 1 inch wide. The pumpkin will shrink significantly because of its high water content, so make sure your slices are big enough.
Place the pumpkin slices on a baking sheet. Bake them at 220F for 20-30 minutes or until pumpkin chips begin to crisp. Turn off oven and let pumpkins sit in the oven while the oven cools. Remove the chips after about 20 minutes, They should be crunchy. Dust the chips with ground cinnamon and serve.
Notes
Store the pumpkin chips in an airtight container up to a day. They are best the day they are baked because they will soften and become chewy after a day.
